“…It seems HR rest should not be condemned, even though it is mostly the HRV analysis being often used for these purposes (Bisschoff, Coetzee & Esco, 2016).  Heart rate variability analysis (HRV): Already introduced "classical" indicators of HRV, such as spectral performance and its density in the established frequency ranges, are a part of athlete monitoring in the scope of overreaching prevention (Makivić, Djordjević, Wilis, 2013;Novotný, 2013;Botek, Krejčí & McKune, 2018). Athletes who are well-rested and well-adapted to the physical load, such as marathon runners, reach a high spectral performance in the HF range, which is an indicator of a higher parasympathetic activity at rest and after a load.…”

“…Stejskal et al (2002) has created a new method of evaluating HRV with associated indicators of spectral analysis from three 5-minute intervals at ortho-clinostatic test (lying -standinglying) -Overall Score (OS), Vagus Activity Index (VA), Sympathicus -Vagus Balance Index (SVB), Functional Age (FA). Botek et al (2018) has added that based on his studies the first interval of lying could be shortened to 1 minute as it does not negatively influence the quality of results. Same author (Botek et al, 2018)…”

The article introduces the issue of monitoring intensively training athletes who wish to avoid overtraining and want their training to be as effective as possible. The current definitions of overreaching and overtraining are addressed, together with the summary of causes, development and prevention of such conditions. The focus of the article is on the overview of relevant diagnostic methods including the latest non-invasive biochemical methods. The complex approach to the selection of psychological and physiological methods to establish the degree of the internal load of athletes is emphasised. A three-degree concept of athlete monitoring according to the demandingness and periodicity of diagnostic methods usage is presented.

Purpose: Many high performance and especially top athletes are still at risk or suffer from total fatigue. Therefore, sports science seeks to develop an objective, sensitive and reliable method of early diagnosis of this fatigue (e.g. heart rate variability – HRV as a modern ob-jective method). The aim of the study was to evaluate whether the HRV monitoring could be a complementary diagnostic tool for overreaching / overtraining in young athletes. Already introduced “classical” indicators of HRV, such as spectral performance and its density in the established frequency ranges, are a part of athlete monitoring in the scope of overreaching prevention We were monitoring the heart rate variability parameters at three different phases of the year-long training cycle and to find out whether in one of these phases we could find athletes showing symptoms of overreaching. Methods: 48 young athletes (33 boys 14.8 ± 1.5 years, 15 girls 14.9 ± 1.7 years) were involved in the study, consisting of 38 boys and 10 girls. There were 15 swimmers (with training volume 9x 1.5‒2 hours a week), 12 artistic gymnasts (with training volume 9x 2‒2.5 hours a week) and 21 badminton players (with training volume 4x weekly 1.5‒2 hours a week). Monitoring was carried out in athletes in three training periods: at the end of the transition period, at the end of the prepared period, at the end of the competition period. Measurements were carried out in the morning. The DiANS PF8 system was used to measure the heart rate variability, the measurements were performed at five-minute intervals: lying-standing-lying. Time and spectral parameters of HRV were monitored. Results: Results of HRV in three periods (HR + rMSSD in lying). Boys: HR (61 ± 8, 64 ± 7, 64 ± 8), rMSSD (85 ± 64; 80 ± 54; 88 ± 59), TS (-0.56 ± 1.53; -0.87 ± 1.4; -0.42 ± 1.44). Girls: HR (65 ± 8; 64 ± 7; 65 ± 8), rMSSD (74 ± 37; 79 ± 35; 83 ± 43), TS (-0.58 ± 1.57; -0.72 ± 1.35); -0.18 ± 0.18). Statistically significant differences (at the significance level = 0.05) among sports were found in Kruskal-Walls ANOVAby Ranks: boys in LF-standing, HF standing, FV, SVB and TS; girls in HF-lying, HF-standing, rMSSD, TP-lying, TP-standing, FV, VA and TS. Conclusion: Monitoring of heart rate variability seems to be a practical tool for prevention of overtraining even in young age. To monitor heart rate variability, we recommend monitoring these parameters: RR, rMSSD, VA, SVB, TS.
