“…A comparison of results obtained in high-class female swimmers, examined in 2006 (Mykhaliuk, 2006) and 2021 (Mykhaliuk et al, 2020;Mykhaliuk et al, 2021aMykhaliuk et al, , 2021b indicates that present-day swimmers were on average 0.5 years (p=0.345) younger, started swimming training 1.2 years (p=0.08) earlier, had no differences in body length, and had insignificantly greater body weight (p=0.152). For HRV parameters, Mo was significantly less by 14.22% (p=0.044), ARI � greater by 51.1% (p=0.029), SI by 78.6% (p=0.048) and the upward trend in AMo/D by 55.38% (p=0.108) was revealed.…”

Purpose: to investigate the influence of the training process of high-class and elite sprint swimmers of both genders on the parameters of the autonomic nervous system, central hemodynamics and physical working capacity. Material & Methods: in the preparatory period of the training process, 145 sprint swimmers (56 females and 89 males) with sports qualifications from CMS (high-class swimmers) to MS-MSIC (elite swimmers) were examined, of which 56 sprint swimmers (31 females and 25 males) in 2006 and 89 sprint swimmers in 2021 (25 females and 64 males). To assess the autonomic regulation of cardiac activity time- and frequency domain methods of HRV analysis were used. Central hemodynamic parameters were examined by an automated tetrapolar rheography. Physical working capacity was measured according to a common technique on a cycling ergometer using a submaximal PWC170 test and calculating the relative value of physical working capacity, i.e. PWC170/kg. Results: comparison of the studied parameters in sprint swimmers examined in 2006 and 2021 showed a significant decrease in PWC170/kg in present-day high-class sprint swimmers with sports qualification CMS (both females and males), by 23.84%, (p=0.0003) and 12.68% (p=0.018), respectively, and in elite male swimmers with sports qualifications MS-MSIC by 9.46% (p=0.017), as well as a downward trend in elite female swimmers with sports qualifications MS-MSIC by 18.28% (p=0.154). Differences in HRV and central hemodynamics parameters were statistically insignificant. Conclusions: in present-day high-class female swimmers, the predominance of the sympathetic arm of the ANS was revealed, the value of PWC170/kg was 23.84% (p=0.0003) lower than in female swimmers of the same level in 2006. There were no significant differences between all the studied indices of elite female swimmers in 2021 and the indices of female swimmers of the same level in 2006. In present-day elite male swimmers and high-class male swimmers, the value of PWC170/kg was lower, respectively, by 9.46% (p=0.017) and 12.68% (p=0.018) than in swimmers of the same level in 2006. A significant decrease in the functional state of modern swimmers-sprinters of both genders against an earlier achievement of qualification standards than their peers in 2006 may be due to a change in the modern methodology of the training process aimed at reducing the training load in the zone of development of general endurance (aerobic orientation) by increasing the load of speed and power (anaerobic) orientation.

“…L. and co-authors showed a significant difference in autonomic support depending on the sport class of swimmers. It has been proved, that the MS-MSIC swimmers, unlike the CMS-First-Class swimmers, were significantly older, had a greater experience in swimming, and body length and weight as well as relative physical performance, lower HR; they tended to have predominantly hypokinetic type of blood circulation, and there were mainly athletes with vagotonia among them [18].…”

The aim of this study was to compare the indices of heart rate variability, central hemodynamics and physical working capacity in female swimmers with different sports qualifications. Materials and methods. The indices of heart rate variability (HRV), central hemodynamics (CH) and physical development (PD) were studied in 44 female swimmers (mean age 15.00 ± 0.36 years, swimming experience – 7.40 ± 0.35 years) depending on their sports qualifications (MSIC, MS, CMS, first- and second-class athletes). To analyze the autonomic regulation of cardiac activity, power spectral and time-domain indices of HRV were used. CH were examined by the method of automated tetrapolar rheography according to W. Kubiček et al. (1970) in Y. T. Pushkar’s et al. modification (1970). Physical working capacity was measured according to the generally accepted technique on a cycling ergometer using the PWC170 submaximal test. The functional state index (FSI) was calculated using the formula patented by authors. Results. Significant differences were found between the indices of HRV, CH and PD in female swimmers with different qualifications. Thus, in the athletes with the MSIC–MS sports qualifications, heart rate was 61.0 ± 3.8 bpm, cardiac index (CI) – 2.978 ± 0.098 L·min-1·m-2 (there was a trend towards the eukinetic type of hemodynamics (TH)), stress index (SI) – 51.16 ± 12.66 relative units (r.u.), PWC170/kg – 16.98 ± 1.22 kgm·min-1·kg-1, FSI – 6.511 ± 0.422 r.u. A decrease in heart rate among them was correlated with a decrease in SI, and an increase in Mo – with a decrease in CI. In female CMS swimmers, heart rate was 61.37 ± 2.83 beats/min-1, CI – 3.021 ± 0.112 l -1min -1·m -2 , a trend towards the predominantly eukinetic TH, SI – 53.73 ± 9.41 r.u., PWC170 /kg– 14.66 ± 0.683 kgm·min-1·kg -1, FSI – 5.683 ± 0.324 r.u. Reduced values of SI and CI were associated with increased values of Mo and PWC170/kg. In first- and second-class female swimmers, heart rate was 63.05 ± 2.22 beats/min, SI – 50.62 ± 6.4 r.u. This group tended to be eytonic and eukinetic. The mean value of the PWC170/kg was 14.19 ± 0.589 kgm·min-1·kg-1 and FSI – 5.953 ± 0.337 r.u. Correlation analysis confirmed the relationship between the decrease in heart rate and CI and the increase in Mo and PWC170/kg. Conclusions. Long-term training in female swimmers at the distance of 50 to 200 meters is accompanied by the significant increase in the PWC170/kg values with qualification improving, 14.19 ± 0.589 kgm·min-1·kg-1, 14.66 ± 0.683 kgm·min-1·kg-1; 16.98 ± 1.22 kgm·min-1·kg-1, respectively, improvements in HRV (decrease in stress index and increase in Mo) and decrease in CI.
