“…In contrast to the usual physical training in the purposeful sporting activity, the task of training athletes to achieve their ultimate motor, psychological and functional results is solved [13,17]. Therefore, in the process of training and competition athletes feel the burden on the body as a whole and on its separate systems.…”

The somatotypological characteristic of acrobats in the literature is insufficiently disclosed, especially from the position of the role of sports selection, training and competitive activities in the formation of somatotype in athletes, whose professional activity is marked by coordination, rhythm and artistic movements, and the early onset of the impact of intense physical activity on their body. The purpose of the work is to establish the peculiarities of the components of the somatotype of acrobats with a high level of sportsmanship of prepubertal, pubertal and postpubertal age. We conducted a survey of 122 girls acrobats of high-level sports skills. As a control group, 126 girls were examined, who were not engaged in sports and studied in schools of Vinnytsia. The girls’ passport age was between 8 and 21 years old. In order to determine the biological age, we used the scheme Avtandilov G. G. (1990). The examined girls were divided into three groups according to the degree of biological maturity: prepubertal period (36 acrobats and 39 girls of the control group); puberty period (31 acrobats and 35 girls of the control group); postpubertal period (55 acrobats and 59 girls of the control group). The somatotypological study was performed according to the estimated modification of the Heath-Carters method (1990). The analysis of the obtained results was carried out in the licensed package “Statistica 5.5” using parametric methods of estimation of indicators. It was found that in the prepubertal period of the ontogenesis in the acrobat and in the girls who were not engaged in sports, the group somatotype was ecto-mesomorphic. In this period, the fatty component of the somatotype in acrobats was significantly lower, and mesomorphic - significantly higher than that of non-sports girls. In the puberty period, the somatotype in control and acrobats had distinct features of the ecto-mesomorphic type. It was found that acrobats in this period had a greater linearity of the body, as evidenced by the significantly higher values of their ectomorphic component of the somatotype. In addition, the size of the endomorphic component was significantly lower in athletes than in the control group. In the postpubertal period of ontogenesis, the F- and L-components were not significantly different, unlike in the previous period, which was characterized by intense puberty development. Acrobats only showed a significant predominance of the mesomorphic component of the somatotype. It can be concluded that the peculiarities of acrobatic sports activity in prepubertal, puberty and postpubertal age have the most significant effect on the development of the fatty and muscular components of the somatotype.

“…This effect is probably not due to the apnea itself. Previous studies have shown that subjective estimates of time (in the range of seconds) may be affected by changes in heart rate (Meissner & Wittmann, ), including a reduction in heart rate during breath holding (Di Rienzo, Hoyek, Collet, & Guillot, ; Jamin et al, ). However, we measured changes in time estimation after participants had already resumed breathing, when heart rate is known to return rapidly to baseline levels (Andersson & Schagatay, ).…”

Manipulating the perception of time affects voluntary breath‐holding duration

et al. 2019

In this study, we examined how time perception, a psychological factor, impacts the physiological response to prolonged, voluntary breath holding. Participants (n = 26) held their breath while watching a distorted timer that made it appear as though time was moving up to 40% faster or slower than real time. We monitored total breath‐holding duration under different time manipulation conditions as well as the onset of involuntary breathing movements. This physiological breaking point marks the end of the “easy‐going” phase of apnea and the start of the “struggle” phase. Based on prior work showing that psychological factors, such as attention and motivation, can influence the length of the struggle phase, we hypothesized that manipulating the perception of time would affect overall breath‐holding duration by changing the duration of the struggle phase, but not the easy‐going phase. We found that time perception can be successfully manipulated using a distorted timekeeper, and total breath‐holding duration correlated with perceived time, not actual time. Contrary to our hypothesis, this effect was attributable to changes in the onset of the physiological breaking point, not changes in the length of the struggle phase. These results demonstrate that unconscious psychological factors and cognitive processes can significantly influence fundamental physiological processes.

“…The problem of the optimal functional state of the cardiovascular system in athletes is determined by the short-term tasks of preparation for a specific sport event, as well as its long-term status, which ensures high achievements of sports for a long period of time. The leading limiting chain in the degree of physical fitness of an athlete is the state of the cardiovascular system [6,7,8]. The functional state of the central hemodynamics enables the most rapid detection of signs of overwork and overtraining.…”

The aim was to determine the main differences in the external structure of the body and the of central hemodynamics parameters in of high-level sports skills volleyball players of the juvenile age with the role of libero, hitters and setters. Materials and methods: 116 volleyball players of high level athletic skill of the youth age from 16 to 20 years old. The control group included 140 practically healthy girls who were not engaged in sports of the corresponding age. Anthropometric investigation was performed according to Bunak’s V.V. and Martirosov’s E.G. method, rheographic – according to the method of Ronkin M.A. and Ivanov L.B. The reliability of the difference between independent quantitative values was determined using Mann–Whitney U-test. Results: It was established that volleyball players have significantly higher total, longitudinal, circumferential dimensions of the body, width of distal epiphyses, transverse diameters of the chest and pelvis in comparison with girls, who are not involved in sport. According to the most parameters of the body external structure the hitters are predominate than setters and libero. In hitters and setters, most anthropo-somatotypological parameters are larger than in nonathletes. The stroke and minute volumes, the impact index, the volume velocity of the blood and the capacity of the left ventricle in volleyball players are significantly higher. Specific peripheral resistance is significantly lower than that of girls who are not involved in sports. Between the volleyball players of different positions in the value of the central hemodynamics parameters, there were no significant differences, except for the impact index, which is significantly higher in libero than in the hitters. Conclusions: The external structure of the body, anthropometric parameters and indicators of central hemodynamics depend of volleyball player’s position and have some peculiarities.
