Headquartered near Chicago, CompTIA is a nonprofit trade association made up of more than 2,000 member organizations and 3,000 business partners. Although the organization focuses on educating and certifying IT professionals, CompTIA also figures prominently in philanthropy and public policy advocacy.

CompTIA certification program overview

CompTIA’s vendor-neutral certification program is one of the best recognized in the IT industry. Since CompTIA developed its A+ credential in 1993, it has issued more than two million certifications.

In early 2018, CompTIA introduced its CompTIA Infrastructure Career Pathway. While you’ll still see the same familiar certifications that form the bedrock of the CompTIA certification portfolio, this new career pathway program more closely aligns CompTIA certifications to the real-world skills that IT professionals need to ensure success when managing and supporting IT infrastructures.

CompTIA certifications are grouped by skill set. Currently, CompTIA certs fall info four areas: Core, Infrastructure, Cybersecurity and Additional Professional certifications.

  • Core Certifications: Designed to build core foundational skills, CompTIA offers four Core certifications: IT Fundamentals+ (a pre-career certification focused on IT foundation framework), CompTIA A+ (focused on user support and device connectivity), CompTIA Network+ (targeting core system connections with endpoint devices), and CompTIA Security+ (focused on entry level cybersecurity skills).
     
  • Infrastructure Certifications: Designed to complement the Network+ credential, you’ll find three Infrastructure certifications: CompTIA Server+ (focused on issues related to server support and administration), CompTIA Cloud+ (covering hybrid cloud, virtual system administration and deploying network storage resources), and CompTIA Linux+ (focused on Linux operating system administration and management).
     
  • Cybersecurity Certifications: CompTIA offers three cybersecurity credentials: CompTIA CySA+ (CySA stands for Cyber Security Analyst, and targets IT security behavioral analysts), CASP+ (CompTIA Advanced Security Practitioner; focuses on professionals who design and implement security solutions), and the CompTIA PenTest+ (Penetration testing, targets professionals who conduct penetration and vulnerability testing).
     
  • Additional Professional Certifications: This category includes several credentials which don’t readily fit into any of the foregoing CompTIA career paths, including: CompTIA Project+, CompTIA CTT+ and CompTIA Cloud Essentials.

CompTIA Core Certifications

CompTIA IT Fundamentals+

CompTIA IT Fundamentals+ is ideal for beginners with a basic understanding of PC functionality and compatibility as well as familiarity with technology topics, such as hardware basics, software installation, security risks and prevention, and basic networking. It’s also ideal as a career planning or development tool for individuals beginning their IT careers or those seeking to make a career change. A single test is required to earn the credential. CompTIA launched a new IT Fundamentals+ test (Exam FC0-U61) in September 2018. This new test focuses on computing basics, database use, software development and IT infrastructure. The English version of the prior test (Exam FC0-U510) retires on July 15, 2019. Exams in other languages retire on December 1, 2019.

CompTIA A+

The CompTIA A+ certification has been described as an “entry-level rite of passage for IT technicians,” and for a good reason. This certification is designed for folks seeking a career as a help desk, support, service center or networking technician. It covers PC and laptop hardware, software installation, and configuration of computer and mobile operating systems. A+ also tests a candidate’s understanding of basic networking, troubleshooting and security skills, which serve as a springboard for CompTIA networking or security certifications or those offered by other organizations.

According to CompTIA, more than one million IT professionals hold the A+ certification. The A+ is required for Dell, Intel and HP service technicians and is recognized by the U.S. Department of Defense. CompTIA released new “Core” exams for the CompTIA A+ credential on January 15, 2019. These new exams provide additional focus on operational procedure competency and baseline security topics. Candidates must pass the Core 1 (exam 220-1001) and Core 2 (Exam 220-1002) exams. The Core 1 test targets virtualization, cloud computing, mobile devices, hardware, networking technology and troubleshooting. The Core 2 exams focuses on installation and configuring operating systems, troubleshooting software, operational procedures and security.

CompTIA Network+

Many IT professionals start with the A+ certification. While the A+ credential is recommended, if you have the experience and don’t feel a need for the A+, you can move directly to the CompTIA Network+ certification. It’s geared toward professionals who have at least nine months of networking experience. A candidate must be familiar with networking technologies, media, topologies, security, installation and configuration, and troubleshooting of common wired and wireless network devices. The Network+ certification is recommended or required by Dell, HP and Intel, and is also an accepted entry-point certification for the Apple Consultants Network. The Network+ credential meets the ISO 17024 standard and just like the A+, it is recognized by the U.S. DoD. A single test is required to earn the certification.

CompTIA Security+

CompTIA Security+ covers network security concepts, threats and vulnerabilities, access control, identity management, cryptography, and much more. Although CompTIA does not impose any prerequisites, the organization recommends that cert candidates obtain the Network+ credential and have at least two years of IT administration experience with a security focus. To obtain the Security+ certification candidates must pass on exam, SY0-501.

Infrastructure Certifications

CompTIA Linux+

The CompTIA Linux+ Powered by LPI certification is aimed at Linux network administrators with at least 12 months of Linux administration experience. Such experience should include installation, package management, GNU and Unix commands, shells, scripting, security and more. The A+ and Network+ certifications are recommended as a preamble to this certification but are not mandatory. Candidates must pass two exams (LX0-103 and LX0-104) to earn this credential. The exams must be taken in order, and candidates must pass test LX0-103 before attempting LX0-104. In 2018, CompTIA began testing a new beta test (XK1-004). The beta test offering ended October 22, 2018. New exams generally follow beta test tests so interested candidates should check the Linux+ web page for updates.

CompTIA Cloud+

As the cloud computing market continues to grow by leaps and bounds, the CompTIA Cloud+ certification has been keeping pace. This certification targets IT professionals with two to three years of experience in storage, networking or data center administration. A single exam, CV0-002, is required. It tests candidates’ knowledge of cloud technologies, hybrid and multicloud solutions, cloud markets, and incorporating cloud-based technology solutions into system operations.

CompTIA Server+

CompTIA Server+ aims at server administrators with 18 to 24 months of experience with server hardware and software technologies, and the A+ certification is recommended. The Server+ credential is recommended or required by HP, Intel and Lenovo for their server technicians. It is also recognized by Microsoft and the U.S. Department of Defense (DoD). A single exam, SK0-004, is required to achieve this credential.

CompTIA Cybersecurity Certifications

CompTIA Cybersecurity Analyst (CySA+)

As cybercrime increases, the requirement for highly skilled information security analysts will continue to increase as well. The Bureau of Labor Statistics (BLS) reports anticipated growth of 28 percent for information security analysts between 2016 and 2026, the fastest rate of growth for all occupations. One of the newer additions to the CompTIA certification portfolio is the Cybersecurity Analyst (CySA+) certification. The CySA+ credential is specifically designed to meet the ever-growing need for experienced, qualified information security analysts.

CySA+ credential holders are well versed in the use of system threat-detection tools, as well as the use of data and behavioral analytics to secure applications and systems from risks, threats and other vulnerabilities. CySA+ certification holders are not only able to monitor network behavior, but analyze results and create solutions to better protect against advanced persistent threats (APTs), intrusions, malware and the like.

CompTIA describes CySA+ as a bridge cert between the Security+ credential (requiring two years’ experience) and the master-level Advanced Security Practitioner Certification (CASP), which requires 10 years of experience. To earn a CySA+, candidates must pass a performance-based exam.

CompTIA Advanced Security Practitioner+ (CASP+)

While CompTIA no longer uses the “master” designation, the highly sought-after CASP+ certification is most certainly a master-level credential. Targeting practitioners, CASP is the only performance-based, hands-on certification currently available from CompTIA. This certification is designed for seasoned IT security professionals who plan, design and implement security solutions in an enterprise environment.

Although this certification doesn’t impose any explicit prerequisites, it’s not a bad idea to earn the Network+ and Security+ certifications before tackling the CASP exam. You should also have 10 years of IT administration experience plus a minimum of five years of technical security experience (thus securing this certification’s place as a “master” credential).

Booz Allen Hamilton, Network Solutions and Verizon Connect, among other companies, require CASP+ certification for certain positions. The U.S. Army and U.S. Navy also accept CASP+ as an industry-based certification required by employees and contractors who perform IT work in DoD data centers. The CASP+ certification requires that candidates pass the CAS-003 exam, which consists of 90 multiple-choice and performance-based questions.

CompTIA PenTest+

The existing additional to the CompTIA certification family is the CompTIA PenTest+. An intermediate-level credential, PenTest+ is designed to complement the CySA+. While CySA+ is defensive in nature (focusing on threat detection and response), the PenTest+ credential is offensive, focusing on using penetration testing to identify and manage network vulnerabilities across multiple spectra.

There are no mandatory prerequisites, but the Network+ and Security+ (or equivalent skills) are highly recommended, along with a minimum of two years of information security experience. Candidates pursuing the cybersecurity career path may take the PenTest+ or CySA+ credential in any order.

The test was released in July 2018, and is focused on communicating and reporting results, analyzing data, conducting penetration testing and scanning, and planning assessments. The test also tests a candidate’s knowledge of legal and compliance requirements.

Additional Professional Certifications

CompTIA Project+

The CompTIA Project+ certification focuses exclusively on project management and is ideal for project managers who are familiar with project lifecycles from planning to completion, who can finish a project on time and under budget. Project managers interested in this certification should have at least one year of project management experience overseeing small- to medium-sized projects. The Project+ credential requires that candidates pass a multiple-choice exam, PK0-004.

CompTIA Cloud Essentials

The CompTIA Cloud Essentials certification is geared toward individuals who understand the business aspects of cloud computing and how to move from in-house to cloud storage. In addition, they should be familiar with the impacts, risks and consequences of implementing a cloud-based solution. A single test is required to earn the credential.

CompTIA CTT+

The CompTIA Certified Technical Trainer (CTT+) certification is perfect for anyone interested in technical training. It covers instructor skills, such as preparation, presentation, communication, facilitation and evaluation, in vendor-neutral fashion. Adobe, Cisco, Dell, IBM, Microsoft and Ricoh all recommend CTT+ to their trainers and accept it in lieu of their own in-house trainer certifications.

Two exams are required for the CTT+ credential: CompTIA CTT+ Essentials (TK0-201) and either CTT+ Classroom Performance Trainer (TK0-202) or CTT+ Virtual Classroom Trainer (TK0-203).

The CTT+ Classroom Performance Trainer and CTT+ Virtual Classroom Trainer are performance-based exams. In this case, you must submit a video or recording of your classroom (or virtual classroom sessions), and complete a form that documents your training preparation, delivery and student evaluations.

In addition to certification levels, CompTIA groups its certifications into several career paths:

  • Information security
  • Network and cloud technologies
  • Hardware, services and infrastructure
  • IT management and strategy
  • Web and mobile
  • Software development
  • Training
  • Office productivity

The CompTIA Certifications page lets you pick a certification level and/or a career path and then returns a list of certifications to focus on. For example, one of the most popular career paths in IT is network administration. CompTIA’s Network and Cloud Technologies career path offers numerous certifications that can help you advance your network administration career, such as IT Fundamentals+, A+ and Network+ (Core certs), along with Cloud+ and Linux+ (Infrastructure certifications) and Cloud Essentials.

Those interested in network security (one of the fastest growing fields in IT) should consider the certifications in CompTIA’s Information Security career path. This includes all four of the Core credentials (IT Fundamentals, A+, Network+ and Security+) along with all cybersecurity certifications (CySA+, PenTest+ and CASP+).

CompTIA provides a comprehensive IT certification roadmap that encompasses certifications from CompTIA as well as a variety of other organizations, including Cisco, EC-Council, Microsoft, (ISC)2, ISACA, Mile2 and more.

Because CompTIA credentials do not focus on a single skill (such as networking or virtualization), CompTIA credential holders may find themselves in a variety of job roles depending on their experience, skill levels and areas of interest. Here are just a few of the possible careers that CompTIA credential holders may find themselves engaged in:

  • A+: Typically, A+ credential holders find work in support roles, such as support administrators, support technicians or support specialists.
     
  • Network+: Network+ professionals primarily work in network-related roles, such as network analysts, administrators or support specialists. Credential holders may also work as network engineers, field technicians or network help desk technicians.
     
  • CySA+ Security Analyst: Common roles for professionals interested in cybersecurity, information security and risk analysis may engage in roles that include security engineers, cybersecurity analysts or specialists, threat or vulnerability analysts, or analysts for security operations centers (SOCs).
     
  • Security+: Security spans a variety of jobs, such as network, system or security administrators, security managers, specialists or administrators, and security consultants.
     
  • Server+: Roles for server professionals include storage and server administrators, as well as server support or IT/server technicians.
     
  • Linux+: Linux professionals often work in roles such as Linux database administrators, network administrators or web administrators.
     
  • Cloud+/Cloud Essentials: Cloud+ credential holders typically work as cloud specialists, developers or system and network administrators. Cloud Essentials professionals tend to work in areas related to cloud technical sales or business development.
     
  • CASP+: Common roles for CASP+ credential holders include cybersecurity specialists, InfoSec specialists, information security professionals and security architects.
     
  • Project+: Project+ credential holders typically engage in project leadership roles, such as project managers, coordinators and directors, or team leads.

While the examples above are by no means exhaustive, they provide an overview of some available careers. Your career choices are limited only by your interests, imagination and determination to achieve your personal goals.

Killexams : Bridging Industry With Classrooms For Women In Tech
Bridging Industry With Classrooms For Women In Tech

Bridging Industry With Classrooms For Women In Tech

New Delhi:

As businesses open up post the Coronavirus pandemic, there is an increasing need to think smart and think 360 degree. IBM has joined hands with Aspire For Her Foundation to help young Indian girls acquire the 360 degree knowledge and skill to make a seamless transition from classrooms to professional pitch in their tech careers.

18 year old Sneha Ganesh, a First Year student has just completed the IBM’s Open P-tech programme and is excited about the opportunities it offers. Sneha says, ”Such an amazing course! As the name suggests, the course was completely suited for anyone who is a beginner. It was very easy to grasp the concepts as they were taught in a visual manner with many real world examples. Not to mention the opportunity that was offered to chat with one of the world's best AI powered chatbots!

I love the Open P Tech platform and can't wait to explore many more courses and earn several badges!”

To girls like Sneha, who are aspiring to make a career in Data Science, this allows to add digital badges to their resume, that point to tangible learning. They are learning at their own pace, own time and beyond their classrooms.

This is a CSR initiative of IBM in India and they have partnered with Aspire For Her foundation, that was launched on Women’s Day 2020 ‘to motivate young women pursue amazing careers,’ says Madhura Dasgupta Sinha, the founder, a banker turned social entrepreneur.

The lockdown began soon after its launch but that did not hinder the growth of this community that now has over 15,000 strong members. There has been a surge of support from Corporates, institutions and individuals for these women.

Madhura says,” All of us at Aspire For Her are excited to launch this learning partnership with IBM's Open P Tech platform.

India lags behind in the Global Gender Gap index, as women do not enter the workforce or drop out early. Aspire For Her wants to change this story. The mission of Aspire For Her is to motivate young women to pursue amazing careers, we want to build a community of more than a million women to unleash the hidden power in the economy of our country.”

IBM is helping this community of women to come close to their dream tech careers.

Research shows that there is a low participation of women in STEM and STEM related roles (Science, Tech, Engineering and Maths). To change that is the aim of both IBM and Aspire For Her.

The course is free for the Aspire For Her members and supporters - ones who sign up on the platform. It is a global platform where they connect with Open P-Tech students across the globe.

While girls acquire knowledge through this programme and become industry ready, Aspire For Her provides opportunities to connect with great organisations looking to hire diverse talent.

Madhura says,” We are building winning mindsets - through career resources like mentors, role models, career previews and of course, through world-class learning opportunities like IBM's Open P Tech - which will take our members one step closer to their dream careers. With forward looking partners like IBM, we are certain that we will be able to attract more women in technology and bridge the gap between their aspirations and action. With many more exciting partnerships and alliances coming up, we are just getting started.”

Jayita Gupta, who pursued a course in Artificial Intelligence says, “The quality of content is beyond amazing! The course got me so hooked that I can't stop myself from going to the next chapter to see what's in store for me, I am absolutely loving it!”

Yashasvi Ghadale’s Quantum Computing lessons with Open P-Tech has taken her close to a dream career. She says,” Quantum Computing is something that I was deeply intrigued about since I first heard about it. With Learning@ASPIRE and IBM Open P-Tech, I was able to learn the science behind Quantum Computing and also explore what opportunities a career in this field holds!”

So why did IBM decide to partner with AFH on this journey?

Rumi Mallick Mitra, Leader, Strategy and New Initiatives for IBM Social Responsibility, India, says, “There is an urgent need for young learners to develop relevant skills that will help them to be successful in the job market. As a leading technology company, we believe this is not only a huge opportunity but also a responsibility that we have, and hence with Open PTECH we are striving to boost skillsets of young learners and provide a way to jump-start their careers.

The courses made available on Open PTECH like cybersecurity, blockchain, design thinking, AI and machine learning are critical 21st century skills for the digital era.

Through Open PTECH we ensure that access to these specialized courses are democratised and available freely. At IBM, we have a strong focus to enable and support women for success in life and STEM careers and ensuring this will contribute to our nation’s success also.

Through Aspire For Her, and with its stellar network of industry experts and mentors, we hope to be a part of the journey that can help these girls and young women to pursue their dreams.”

Just the help women in STEM need to leap to the careers they aspire for!

Killexams : Relation between physical exertion and heart rate variability characteristics in professional cyclists during the Tour of Spain

Many changes in physiological variables occur with chronic exposure to intense training loads. When these training loads become excessive, a broad class of terms is used to describe the attenuation in subsequent training and performance response. The most common are overexertion, overreaching, and overtraining, all of which typically involve unfavourable cardiovascular, neuromuscular, and/or hormonal alterations.1,2 To overcome the need for continual invasive measurements, exercise physiologists, coaches, and athletes often use resting heart rate (HR) to monitor fatigue and recovery relative to repeated training stimuli.1 However, the data on resting HR are equivocal, showing lower, normal, and faster resting HR in athletes suffering from these maladies.3,4 The reason for this disparity is not completely understood. Some theories suggest that these responses are due to exhaustion of the neuroendocrine system or a decrease in catecholamine sensitivity.3–6 Several studies suggest that alterations in autonomic balance that accompany strenuous exercise can be examined non-invasively by assessing heart rate variability (HRV).7–13 Overtraining induced by heavy training increases cardiac sympathetic modulation during supine rest and attenuates baroreflex mediated response during an orthostatic manoeuvre.12,14 Conversely, optimal exercise training increases cardiac vagal activity in relation to sympathetic activity.15,16

HRV is a function of the synergistic action between the two branches of the autonomic nervous system, which act in balance through neural, mechanical, humoral, and other physiological mechanisms to maintain cardiovascular variables in an optimal range during changing external or internal conditions. Disease, emotional stress, and physical stress can all influence autonomic balance. accurate reports also show that HRV is inversely related to all-cause and cardiovascular disease mortality.17,18 Thus, the examination of HRV relative to parasympathetic activity alone or in combination with sympathetic nervous activity may provide a functional, non-invasive assessment of cumulative exertion and related fatigue.

A syllabu not fully examined in the literature related to chronic physiological stress is relative training volume and intensity. We theorise that a technique that may help in the examination of chronic exertion and HRV is to account for exercise training volume and intensity by using the TRIMPS concept initially proposed by Banister and Calvert19 and modified by Foster et al20 where TRIMPS stands for training impulse. In this paper, we examine the HRV response of professional road cyclists competing in a three week stage race known as the Vuelta a España, the third of the three annual classic stage races after the Giro d’Italia (April) and Tour de France (July). This type of race typically lasts 21–22 days, entails 70–90 hours of competition, and covers 3000–3500 km with only two days of rest. Despite the long duration of the daily stages (four to five hours and 150–200 km), exercise intensity is often high during the more physically taxing events, such as riding over high mountain passes, time trials, sprints, and “breakaways”.21 On the basis of a report suggesting that the basal activity of the pineal gland, adrenal glands, and testis is decreased after such an event,6 we believe that the nature of this race lends itself to the examination of HRV during chronic exposure to prolonged heavy exertion.

METHODS

We recruited eight male cyclists from one of the world’s leading professional cycling teams. All were highly competitive in the professional category. Several finished within the top 10 of the Giro d’Italia, Vuelta a España, or Tour de France between 1995 and 2002. Their age (mean (SEM) 27 (1) years), height (179 (1) cm), body mass (65.5 (2.3) kg), and percentage body fat (8.3 (0.1)%) were assessed earlier in the season and before the race. Body fat was estimated using a skinfold method described elsewhere.6 Maximum rate of oxygen consumption (V˙o2max) for each rider was assessed four to five weeks before the race. All the subjects were in good health without arrhythmic events, as established by a normal physical examination including electrocardiograph and echocardiograph evaluation during the preceding year. All had normal endocrine and metabolic functions and no family history of diabetes mellitus. Written, informed consent was obtained from each subject in accordance with the regulations of the Universidad Complutense, Madrid, Spain.

Characteristics of the 2001 Vuelta a España

The Vuelta a España begins in late August/early September on the Spanish Mediterranean coast. In 2001, it included 21 daily race stages, with two days of rest (day 10 and day 17) (table 1). During this three week period, a total of 2989 km were covered and the total time raced for the overall winner was ≈ 71 hours. The average total speed for this event was 42.5 km/h. The mean (SEM) daily distance covered per stage was 143 (13) km at altitudes ranging from sea level through to 2000 m above sea level. Most daily stages started at about 1330 hours and finished between 1700 and 1730 hours. Temperature ranged from 17°C to 30°C. Nutrition, hydration, timing of food intake, and sleep were kept constant throughout the entire three week period. This is normal practice in cycling competitions to maintain circadian rhythms and consistency among riders.22 Mean daily food intake during this type of competition is about 840 g carbohydrate, 200 g protein, and 158 g fat corresponding to about 23.5 MJ.22

Laboratory exercise testing and race monitoring

During the four to five weeks before the race, all subjects performed an incremental exercise test to determine reference HRs corresponding to the ventilatory threshold (VT) and the respiratory compensation point (RCP). All tests were performed on a bicycle ergometer and followed a ramp protocol until exhaustion. Workload during these tests increased 25 W/min until exhaustion. These methods have been described in detail elsewhere.21 HR was continuously recorded during the tests with a telemeter (Polar S710; Polar Electro, Oy, Finland). The workload corresponding to VT was determined using the criteria of an increase in both the ventilatory equivalent of oxygen (Ve/Vo2) and end tidal partial pressure of oxygen (Peto2) with no concomitant increase in the ventilatory equivalent of carbon dioxide (Ve/Vco2).23 The workload eliciting the RCP was determined using the criteria of an increase in both Ve/Vo2 and Ve/Vco2 and a decrease in end tidal partial pressure of carbon dioxide (Petco2).23

We also recorded HR for each rider during each stage of the race using the Polar S710 telemeter. All data recorded were analysed using a computer program (Polar Precision Performance 3.02; Polar Electro), which allows the user to select reference HR values relative to established levels of exercise intensity. To examine the exertional intensity/volume relation for each rider during the race, we divided recorded HR values into three phases according to the reference values obtained during a previous ramp cycle ergometer test. These phases were: I (light intensity; <VT); II (moderate intensity; between VT and RCP); III (high intensity; >RCP).

To estimate the exertional volume and intensity for each rider, we adopted a modified approach proposed by Foster et al19 to the original TRIMPS concept published by Banister and Calvert.20 This modified TRIMPS model integrates total exercise participation time and relative HR based on the phases outlined above into an exercise volume/intensity measurement. This measurement is obtained by taking the rider’s HR for the time spent in each phase and multiplying the accumulated time spent in this phase by a multiplier. Specifically, HR during phase I is scored as 1, HR during phase II is scored as 2, and HR in phase III is given a score of 3:

Total TRIMPS  =  (min of phase I HR min × 1) + (min of phase II HR min × 2) + (min of phase III HR min × 3)

HRV analysis

To assess HRV we collected baseline (day 0) RR intervals two days before the race and during the two allotted rest days after stages 1–9 (day 10) and stages 10–15 (day 17). We used these days because our data were obtained under field testing conditions in which rider time was at a premium relative to their competition schedule. We were unable to collect data on the last day of the event because this was not a rest day and riders were preparing for the final day of racing (table 1). We used an IBM compatible PC equipped with a program for signal processing and HRV analysis (Polar Precision Performance SW 3.02). A two channel electrocardiograph signal was detected by a Polar Heart Rate Monitor and transmitted online to a Polar S810 watch receiver. The computer program labelled each QRS complex, and the resulting signal was passed through a filter that eliminates ectopic beats and artifacts. In addition, an RR interval tachogram was displayed for manual editing, and areas of ectopy or artefact were identified and removed by manual deletion. Each edited RR interval was replaced with an average value. Segments containing more than 15% of edited RR intervals were interpreted as a premature beats and excluded from data analysis. These segments accounted for <2% of edited 10 minute intervals in every subject. The filtering techniques are described in previous reports.24,25

Resting RR intervals were collected in the supine position for 15 minutes during baseline on day 10 and day 17. HRV was estimated from the last four minutes of data collection. Data were collected on subjects each test morning when they woke up in a semidarkened room. The stability and reliability of time and frequency domain measures of short term resting HR and HRV assessed day to day for five consecutive days in healthy active men has been reported previously. The authors of these reports suggest that, when HRV is measured in early morning, after an overnight fast and before any strenuous activity, the measurements are highly reproducible (intraclass correlation coefficient >0.97 for all HR and HRV indices).26 This was the procedure followed in our study, HRV measurements on days 10 and 17 being performed in early morning after an overnight fast. Because we were operating under field conditions, all subjects breathed spontaneously. Frequency and time domain methods were used to calculate HRV.

Time domain analysis

To assess the time domain measures, we analysed the standard deviation of all RR intervals (SDNN) over the given measurement period and the square root of the mean of the sum of the squares of differences between adjacent RR intervals (rMSSD). SDNN reflects the parasympathetic and sympathetic influence, and rMSSD is considered to be an index of parasympathetic modulation of HR.27

Frequency domain analysis

We used an autoregressive model to estimate the power spectrum densities for the frequency domain. The power spectra were quantified by measuring the area in three frequency bands. We reported the high frequency power (PHF; 0.15–0.40 Hz; measures the beat to beat variability and appears to be mediated by variations in parasympathetic activity), low frequency power (PLF; 0.04–0.15 Hz; thought to reflect both vagal and sympathetic activities), and total frequency power (PT; 0.04–0.40 Hz; represents overall variability).27

Statistical analysis

We began our analysis using a repeated measures multivariate analysis of variance to determine overall statistical effects for HR and HRV indices. If a significant statistical result was noted, a Fisher’s least significant difference, post hoc analysis was undertaken. TRIMPS data were examined for absolute values, as well as for relative contributions—that is, TRIMPS/day. To normalise their distribution, we applied a natural logarithmic transformation (ln) to all HRV variables analysed in the frequency domain (PHF, PLF, PT). We used a Pearson product-moment correlation analysis to examine the relation between the exercise volume and intensity—that is, TRIMPS—and resting HR and HRV.

RESULTS

The mean (SEM) physiological characteristics of the riders in this study included a V˙o2max of 75.6 (2.2) ml/kg/min, maximal power output of 498 (14) W, and HRmax of 191 (1) beats/min. Average VT occurred at a power output of 325 (13) W (78.9 (2.5)% of V˙o2max) and a HR of 152 (3) beats/min (79.6 (1.5)% HRmax). Average RCP occurred at a power output of 438 (12) W (91.3 (1.4)% of V˙o2max) and a HR of 176 (3) beats/min (90.5 (1.1)% HRmax).

Overall, our repeated measures multivariate analysis of variance showed significant effects for TRIMPS and all resting HR and HRV variables (p<0.001). Only the TRIMPS data showed significant post hoc effects after an analysis of group means. However, significant correlations were found for all HRV indices accumulated in stages 10–15. Details of these findings are outlined below.

Trimps

Stages 1–9 of racing were characterised by 1235 km of riding inclusive of two days of time trials (56 km), five days of flat, mass start stage racing (823 km), and two days of mountain stages (356 km). Total TRIMPS experienced for riders during this period was 2466 (90) (274 (10) TRIMPS/day; table 2). Day 10 was a rest day. Stages 10–15 were characterised by 923 km of riding inclusive of one up hill or mountain time trial (17 km), two days of flat, mass start stage racing (377 km), and three days of mountain stages (529 km). Total TRIMPS experienced for riders during this time period was 2055 (65) (343 (11) TRIMPS/day).

Table 2

 TRIMPS accumulated for professional cyclists participating in the 2001 Vuelta a España

Comparisons of total TRIMPS showed that even though overall TRIMPS for stages 1–9 were greater than for stages 10–15 (p<0.0002), average TRIMPS/day was greater during stages 10–15 (p<0.01). Specific phase comparisons showed a greater accumulation of TRIMPS for phase I (p<0.007) and phase III (p<0.0005). However, no differences were noted for phase II absolute TRIMPS. When expressed as TRIMPS/day, in phase I (p<0.02) and phase II (p<0.001) they were greater for stages 10–15 than for stages 1–9, despite four fewer days of racing during the latter time period.

HRV analysis

Post hoc analysis examining group mean HRV comparisons showed no significant statistical effect between baseline (day 0), day 10, and/or day 17 (table 3). Furthermore, no significant correlation was observed between TRIMPS or TRIMPS/day accumulated during stages 1–9 and either time domain HRV indices (fig 1A, C) or frequency domain HRV indices (fig 2A–F). However, a significant inverse correlation was observed for total TRIMPS accumulated in stages 10–15 and each HRV component: rMSSD (r  =  −0.93; p<0.001; fig 1B), SDNN (r  =  −0.94; p<0.001; fig 1D), lnPLF (r  =  −0.79; p<0.02; fig 2B), lnPHF (r  =  −0.94; p<0.001; fig 2D), and lnPT (r  =  −0.97; p<0.001; fig 2F). The same results were observed when we expressed the data as TRIMPS/day for each HRV index (data not presented).

DISCUSSION

The principal finding from this trial is the observation that changes in supine resting HRV are inversely related to exercise volume and intensity. Although several other groups have examined the relation between “overtraining” and HRV,8–13 this is the first paper to examine the relation between HRV and chronic exposure to heavy exercise after adjustment for the training volume/intensity relation. Although we did not examine overtraining/overreaching per se, we believe that adjusting for the volume/intensity relation is important for future studies investigating the relation between HRV and periods of heavy physical exercise for the following reasons. Firstly, athletic training and competition are stochastic and prone to changing intraindividual responses to an imposed exercise challenge. Inherent within this paradigm is the idea that adaptation is, in and of itself, allostatic and dependent on a variety of mechanisms including psychosocial, neuroendocrine, musculoskeletal, and cardiovascular responses. A fundamental difficulty in using HRV to examine changes associated with chronic bouts of heavy physical exertion is accounting for individual responses to and from a training stimulus.

For example, during each one of the professional three week stage races (Giro d’Italia, Tour de France, Vuelta a España), some riders are selected to try to win stage victories and are often protected by drafting techniques. This reduces physical exertion in an effort to “save” that cyclist for greater effort needed later in the race or overall competition in general. To accomplish this, other riders, known as domestiques, play a supportive role by blocking and working for the rider selected to attempt a stage win. Inevitably, these riders expend a greater amount of energy during competition and training (fig 3). Examining the group means in our study suggests a trend for various HRV indices to increase from baseline to day 10, and then generally be maintained through to day 17 of stage racing (table 3). Although not significant, all HRV indices tended to increase during the first 10 days of racing and remain higher than baseline through to day 17. However, the statistical error—that is, SEM—surrounding the mean of the data suggests that there is great intraindividual variability in HRV during race conditions, which will prevent differences in the mean group variables between time points reaching statistical significance. Therefore, quantifying physical exertion relative to training volume and intensity seems to be a more logical way of examining the relation between an athlete’s response to exercise training and competition. To adequately examine the relation between HRV and physical exertion in the field, it is necessary to account for the relative degree of physical effort expended by each rider. We illustrate this in our present study using a modified TRIMPS concept.

(B, D) Data for a domestique. Black represents phase I, white phase II, and grey phase III. The letter “R” on the x axis represents rest days, when riders performed light intensity recovery rides lasting about 120 minutes.

From these results, there seems to be little correlation between HRV and exercise volume during stages 1–9. However, strong inverse correlations are observed between HRV and exercise volume and intensity in stages 10–15. One of the most distinguishing features between these two periods is the average TRIMPS/day accumulated by the riders. Even though each rider rode a greater distance and accumulated more TRIMPS in stages 1–9 than in stages 10–15, it is notable that more TRIMPS/day were accumulated during the second time period. Overall, however, we suggest that the HRV alterations observed are due to the cumulative physical effort over all 15 stages of racing. This pattern is observed by examining the HRV response of a team leader and domestique in figs 1 and 2: a decrease in HRV is observed for the domestique after 15 stages of racing, whereas there is little change in the HRV values of the team leader. Unfortunately, there are no similar trials with which to compare our results. The closest may be those reports examining HRV, exercise, and/or “overtraining.”

For example, Uusitalo et al28 examined changes in baroreflex sensitivity, plasma volume, and resting HR and blood pressure variability induced by heavy training in female endurance athletes. During this trial, nine athletes increased their training intensity and volume component by 100–130% for six to nine weeks. In five overtrained athletes, defined as having a decrease in V˙o2max, PLF increased during supine rest. The same group, using a similar trial design, later confirmed the results of this trial.12 Again, five subjects were defined as being overtrained, showing a decrease in V˙o2max, and an increase in low frequency spectral power PLF during supine rest. Changes in total spectral power PT during standing correlated positively with changes in V˙o2max. The authors concluded that heavy training can increase cardiac sympathetic modulation during supine rest and attenuated biphasic baroreflex mediated response appearing just after shifting to an upright position.

In contrast, Hedelin et al29 reported HRV findings in nine elite canoeists involved in a six day training camp consisting of cross country skiing and strength training totalling about 13 hours, which corresponded to a 50% increase in the athletes’ training load. During this short period of vigorous training, time to exhaustion, V˙o2max, and maximal lactate decreased. However, no group changes in HRV were found at rest or after a tilt test. Although resting HR did decrease, this was attributed to an increase in plasma volume. The authors concluded that HRV did not seem to be affected by short term “overtraining.” In a case study presented by the same group, however, increased high frequency and total powers (PHF and PT) in the supine position were observed in one athlete after a diagnosis of overtraining.9 Interestingly, the authors concluded that there is a shift toward increased HRV, particularly the high frequency range, together with a reduced resting HR. They further suggest that this causes a cardiac autonomic imbalance with extensive parasympathetic modulation when overtrained. Thus, some disagreement exists in the literature about HRV and overtraining. We hypothesise that true overtraining and heavy exertion would attenuate the HRV response for several reasons. Firstly, HR is intrinsically regulated by the balance between the sympathetic and parasympathetic nervous system. In brief, stimulation of the sympathetic nervous system increases HR through the release of adrenaline (epinephrine) and noradrenaline (norepinephrine), which accelerate depolarisation of the sinoatrial node. The same catecholamines also increase cardiac contractility. Parasympathetic activity is regulated by the release of acetylcholine, which acts on the vagus nerve to attenuate sinus discharge. Both of these factors can influence HRV and are referred to as autonomic balance. Optimal exercise conditioning, coupled with adequate recovery, creates a healthy “imbalance” per se between the activities of the sympathetic and parasympathetic nervous system in favour of greater vagal dominance. This is due to an increase in parasympathetic activity and possibly a decrease in sympathetic activity.30,31 In addition, training may also decrease the intrinsic rate of firing of the sinoatrial node pacemaker tissue,32,33 which accounts for the bradycardia associated with highly conditioned athletes.32,33 Thus, if excessive training were to alter the high frequency component of HRV—that is, parasympathetic tone—one would expect to see a decrease in the variable.

Secondly, and in support of this premise, overtraining syndromes are characterised by a decreased intrinsic sympathetic activity and sensitivity of target organs to catecholamines, as indicated by decreased catecholamine excretion, decreased β adrenoceptor density, decreased β adrenoceptor mediated responses, and increased resting plasma noradrenaline concentrations and responses to exercise.34 Earlier studies on athletes showed that changes in activity of the autonomic nervous system, as assessed by HRV during a dynamic orthostatic test, may detect signs of fatigue that may result in overtraining. An impaired baroreflex response after the tilt is such a marker.12,14 Although we attempted to perform an “orthostatic test” by having the cyclists stand for six minutes after supine HRV data had been collected, the orthostatic test is typically performed using a tilt table. Our data are not shown because we feel that they are inconsistent and show great variability—that is, SD and SEM. We attribute this to several possibilities including accessory muscle movement while the athletes were maintaining their balance or “fidgeting.” In addition, HRV in general has been shown to be greater in athletes than in those predisposed to cardiovascular events,17,18,22,26 further suggesting that HRV would increase during a “state of health” or decrease during a state of disease or stress.

Using as an example the study of Hedelin et al,29 the athletes (canoeists) were probably not overtrained, but simply overreached. Moreover, although the training was intense, it only amounted to about two hours a day. Although strenuous and tiring, it may have been insufficient to elicit any change in autonomic balance in such a short period of time. This is supported by data in our study showing no changes in HRV after 10 days of competitive riding at about four to five hours a day. Support for our hypothesis comes from the study of Pichot et al13 who monitored the HRV of seven middle distance runners undertaking three weeks of heavy training, followed by a relatively restful week. The results showed a significant and progressive decrease in parasympathetic indices (by 41%) during the three weeks of heavy training. This was followed by a 46% increase during the rest week. Conversely, indices of sympathetic activity followed the opposite trend. The most obvious explanation for the fact that we did not find HRV differences across the three measurement periods in our study is the individual variance in TRIMPS. Thus, the HRV comparison within the whole group is probably affected by individual volume and intensity of exercise expended during the race, which is supported by our observation that HRV correlated negatively with TRIMPS.

Another explanation for our findings relates to cardiac fatigue and alterations in the neuroendocrine axis, which is accompanied by a reduction in cardiac β adrenergic responsiveness associated with exercise.35 One cause of these responses may be the sustained tachycardia of nearly 21 days of continuous professional racing. Left ventricular function has been shown clinically to be transiently decreased after supraventricular tachycardia(s) or rapid pacing.36–38 These types of change, in addition to a reduction in cardiac β adrenergic responsiveness, have been noted after as little as one hour of exercise,35,39 as well as after the completion of an Ironman triathlon.40 The reduced responsiveness to catechols also correlates closely with the degree of cardiac fatigue, as measured by a reduction in ejection fraction. Another factor that may also explain the inverse relation between TRIMPS and HRV indices is the potential for adrenal exhaustion associated with 21 day stage races. Previous work from Lucia et al6 during the 1999 Vuelta a España has shown a decrease in basal concentrations of several hormones associated with the basal activity of the pineal gland, adrenal glands, and testis, suggesting a degree of adrenal exhaustion in professional riders during this type of activity.

Our study has several limitations because of its nature as a field study. Firstly, we did not have a control group with which to compare our data. This may be partially overcome through our analysis, which accounted for each rider’s relative degree of exercise volume and intensity. Secondly, we were not able to control for breathing during this trial, as this was performed under professional racing conditions and “extracurricular” rider time was at a premium. Previous research has shown that uncontrolled breathing may cause a shift of the respiratory peak, as assessed by frequency domain analysis, from high frequency to the lower frequencies and result in an increase in low frequency power (PLF) and a decrease in high frequency power (PHF).27 However, riders were compared against themselves under consistent resting conditions and showed no decrease in high frequency power, which has been shown not to influence HRV outcomes appreciably.41 Lastly, it should be mentioned that alterations in HRV are influenced by simultaneous training induced changes that are also non-linear.42,43 Thus, the best way to study true autonomic balance would be by the use of drugs to block the sympathetic and/or the parasympathetic system, as HRV only gives an indirect estimation of autonomic balance. However, this approach would be impractical in day to day monitoring of training athletes.

Take home message

Overtraining and overreaching are not clearly understood or easily monitored. The use of HRV shows promise in diagnosing these maladies, but may be confounded if group mean responses that do not account for individual differences are examined. The TRIMP concept offers a solution to this problem that is simple to administer by accounting for the individual exertion response of each athlete to a training stimulus.

Our data strongly suggest that changes in HRV are directly related to volume and intensity of exercise, as athletes who showed the greatest cumulative physical exertion also showed the largest decrease in supine HRV. We therefore suggest that future investigations of the relation between long periods of chronic physical exertion should devise means of quantifying the intensity/volume relation of the athletes under investigation. Given the extent and ease of use of HR monitors today, this can be easily accomplished for most endurance athletes using this type of HR monitoring technology.
