“…At the same time, with increasing tension regulating heart rhythm appears strengthening neuro-hormonal activation centers and parasympathetic parts of the autonomic nervous system. This result confirms data from other authors (Lucini et al, 2014).…”

A longitudinal study of the dynamics of physiological indicators of highly qualified handball players was proposed to conduct. The challenges of studying the characteristics and dynamics of the indicators of the cardiovascular system, exercise capacity, heart rate, functional state, heart rate variability, autonomic regulation and energy of highly qualified handball players during the annual macro cycle have been analyzed. Data led to the conclusion that the adaptive response of the athletes' bodies at the training load in the run proceeds with different voltage regulation systems. It was revealed that some athletes achieved high level of fitness and was accompanied by considerable stress adaptive mechanisms of the cardiovascular system in violation of the regulatory function of the autonomic nervous system. There was defined no significant differences in terms of heart rate and stroke volume were observed. However, in the competitive period marked economization in the vascular unit of blood circulation and decrease in activity of the sympathetic influences was determined. The balance of the autonomic nervous system was characterized type of vegetative regulation of cardiac rhythm. There has been a slight increase in activity of the parasympathetic autonomic nervous system alone, which combines the high ability to mobilize sympathetic activity. In fact, this may indicate a functional imbalance of the cardiovascular system of athletes. It is expected that the analysis of heart rate provides a fairly informative data on the functional status of athletes and allows to make adjustments in the proper training and preparation of the recovery process.

“…Simultaneously with increasing of heart rate regulation's intensity of older age group's wrestlers there appears activation of neurohumoral centers and parasympathetic link of vegetative nervous system. The received result proves the data of other authors [14,19] about increasing of neurohumoral mechanisms of heart rate's vegetative regulation in conditions of sportsmen's intensive muscular functioning.…”

Purpose: the aim of the work was to study the characteristics of vegetative regulation of cardiac rhythm in athletes of high qualification of different age groups. Material: 26 wrestlers of Greco-Roman style of high qualification aged 19-34 years old were studied. Vegetative regulation was assessed by statistical analysis of heart rate variability using cardiac monitors «Polar RS800CX». Results: the results showed that the wrestlers of older age group has a greater level of tension of regulation of heart rhythm for compared with young athletes. This is confirmed by the reduced values of the mean square deviation RR-intervals and triangular index. According to the results of spectral analysis of cardio revealed activation of parasympathetic tone of the autonomic regulation of the heart rhythm of wrestlers in older age group, compared with young athletes. The increase of tension of regulation of heart rate in the wrestlers of older age group accompanied by a slowdown of aperiodic and periodic oscillations of cardio intervals. Conclusions: the high level of tension of regulation of heart rhythm in older wrestlers group (26)(27)(28)(29)(30)(31)(32)(33)(34) accompanied by the activation of neurohumoral centers and parasympathetic link of vegetative nervous system. Key words: vegetative regulation of heart rate, wrestlers of high qualification, age groups, spectral analysis of cardio intervals.

“…Therefore, a question remains: what could explain the differences in postexercise parasympathetic reactivation between the three exercise modalities? Nowadays, it is widely accepted that HRR and HRV dynamics after exercise are affected mainly by exercise intensity (Lucini et al 2014 ). In the present study, maximal effort was attained in all exercise modes, but for different absolute values of VO 2 and HR to satisfy the energy demands of working muscles (see Table 2 ).…”

PurposeThe main purpose of this study was to investigate parasympathetic reactivation of the heart [evaluated through heart rate recovery (HRR) and HR variability (HRV)] after maximal cardiopulmonary exercise testing (CPET) using three different exercise modalities.MethodsTwenty healthy men, aged 17 to 28 yr, performed three maximal CPETs (cycling, walking, and running) separated by 72 h and in a randomized, counter-balanced order. HRR was determined from the absolute differences between HRpeak and HR at 1–3 min after exercise. The root mean square of successive R-R differences calculated for consecutive 30-s windows (rMSSD30s) was calculated to assess the parasympathetic reactivation after maximal CPET.ResultsLower HRpeak, VO2peak and energy expenditure were observed after the cycling CPET than the walking and running CPETs (P < 0.001). Both HRR and rMSSD30s were significantly greater during recovery from the cycling CPET compared to the walking and running CPETs (P < 0.001). Furthermore, Δ rMSSD (i.e. resting minus postexercise rMSSD every 30 s into the recovery period) was positively related to the resting high-frequency component (HF), rMSSD, and standard deviation of all normal R-R intervals (SDNN) (rs = 0.89 to 0.98; P < 0.001), and negatively related to the resting low-frequency component (LF) and sympathovagal balance (LF:HF ratio) after all exercise conditions (rs = −0.73 to −0.79 and −0.86 to −0.90, respectively; P < 0.001).ConclusionsThese findings support that parasympathetic reactivation after maximal CPET (as assessed by HRR and rMSSD30s) depends on exercise modality and cardiac autonomic control at rest.
