Objective: A meta-analysis was conducted on the effect of overload training on resting HR, submaximal and maximal exercise HR (HR), and heart rate variability (HRV), to determine whether these measures can be used as valid markers of over-reaching. Methods: Six databases were searched using relevant terms and strategies. Criteria for study inclusion were: participants had to be competitive athletes, an increased training load intervention had to be used, and all necessary data to calculate… 

Monitoring Athletic Training Status Through Autonomic Heart Rate Regulation: A Systematic Review and Meta-Analysis

Increases in vagal-related indices of resting and post-exercise HRV, post-Exercise HRR, and HR acceleration are evident when positive adaptation to training has occurred, allowing for increases in performance.

Monitoring training status with HR measures: do all roads lead to Rome?

This review contends that most of the contradictory findings are related to methodological inconsistencies and/or misinterpretation of the data rather than to limitations of heart rate measures to accurately inform on training status, and provides evidence that measures derived from 5-min recordings of resting and submaximal exercise heart rate are likely the most useful monitoring tools.

A pilot study on quantification of training load: The use of HRV in training practice

This study confirms that HRV changes during exercise and recovery phase are affected by both intensity and physiological impact of the exercise, and provides an objective and rational TL index.

Minimally Invasive Ways to Monitor Changes in Cardiocirculatory Fitness in Running-based Sports: A Systematic Review.

In summary, when executed, analyzed, and interpreted appropriately, submaximal protocols can provide valuable information regarding changes in athlete cardiocirculatory fitness.

Submaximal heart rate seems inadequate to prescribe and monitor intensified training

(Sub)maximal heart rate decreased after the TFL, however, this decrease is unrelated to the change in performance and heart rate seems inadequate to prescribe and monitor intensified training.

Heart Rate Variability Monitoring During Strength and High-Intensity Interval Training Overload Microcycles

Moves of HR and Ln RMSSD during an orthostatic test could reveal different autonomic responses following ST or HIIT which may not be discovered by supine or standing measures alone, and the use of rolling averages may alter these relationships differently on group and individual level.

Evaluation of nocturnal vs. morning measures of heart rate indices in young athletes

It is concluded that HR and RMSSD obtained during nocturnal sleep and in the morning did not differ significantly and provide a potential tool for long-term monitoring of young endurance athletes.

Training Adaptation and Heart Rate Variability in Elite Endurance Athletes: Opening the Door to Effective Monitoring

How longitudinal HRV monitoring in elites is required to understand their unique individual HRV fingerprint is revealed and it is demonstrated for the first time how increases and decreases in HRV relate to changes in fitness and freshness, respectively, in elite athletes.

Reliability and validity of time domain heart rate variability during daily routine activities – an alternative to the morning orthostatic test?

Summary Study aim: To determine the reliability and validity of a time domain heart rate variability (HRV) index during free-living physical activity (FLPA). Material and methods: Eight white-collar

Investigating the use of pre-training measures of autonomic regulation for assessing functional overreaching in endurance athletes

Examination of resting HRV and ProCVT in FOR athletes found same-day resting autonomic measures are insufficient in predicting alterations to performance or exercising HR measures following overload training.

Relation between heart rate variability and training load in middle-distance runners.

This study confirmed that heavy training shifted the cardiac autonomic balance toward a predominance of the sympathetic over the parasympathetic drive, and heart rate variability appeared to be a better tool than resting heart rate to evaluate cumulated physical fatigue, as it magnified the induced changes in autonomic nervous system activity.

Heart rate variability measures: a fresh look at reliability.

It is concluded that short-term HRV parameters are subject to large day-to-day random variations and reliability indexes tended to improve during paced breathing.

Abruptly intensified physical training results in an altered autonomic cardiovascular activity towards parasympathetic inhibition and sympathetic activation that can be monitored by means of HRV and BRS analyses and might provide useful markers to avoid the overtraining syndrome.

Heart Rate Variability in Athletes

There is a strong need for basic research on the nature of the control and regulating mechanism exerted by the autonomic nervous system on cardiovascular function in athletes, preferably with a multidisciplinary approach between cardiologists, exercise physiologists, pulmonary physiologists and coaches and biomedical engineers.

Night heart rate variability during overtraining in male endurance athletes.

HRV during sleep does not seem to be a valid marker of overtraining in male endurance athletes, and longitudinal studies with elite or sub-elite athletes are needed to determine if spontaneously developed overtraining results in the same response.

Heart Rate Monitoring

There appears to be a small day-to-day variability in HR and a steady increase during exercise has been observed in most studies, and the effects of overreaching on submaximal HR are controversial, with some studies showing decreased rates and others no difference.

Reliability of postexercise heart rate recovery.

It is concluded that passive postexercise HR recovery reliability is heterogeneous, and raw HR is the desired method to describe it.

Variation in Heart Rate During Submaximal Exercise: Implications for Monitoring Training

Heart rates were determined during each of the 4 exercise intensities of increasing intensity and during the 1‐minute recovery period after each stage and the standard error of measurement of submaximal heart rate was 1.4%.

Poincaré plot parameters are suggested to be used to indicate fatigue and/or prevent OT and corroborate the traditional time‐ and frequency‐domain analysis assessment of HRV.
