Why the study?
To evaluate the effect of an identical training process on the functional state of high-level male and female sprint swimmers.
Does gender affect heart rate variability, central hemodynamics, and physical working capacity in high-level sprint swimmers undergoing an identical training process?
Does gender affect heart rate variability, central hemodynamics, and physical working capacity in high-level sprint swimmers undergoing an identical training process?
High-level male and female sprint swimmers undergoing identical training show no significant differences in heart rate variability and central hemodynamics, but males have a higher relative physical working capacity.
Leaves open whether identical training yields equivalent autonomic/hemodynamic adaptations by sex in elite swimmers; hypothesis-generating, needs prospective validation.
Purpose: to study the effect of an identical training process on the functional state of high-level sprint swimmers of both genders. Material and methods. The heart rate variability indices, central hemodynamic parameters and PWC170/kg measurements were compared between 86 male and 42 female swimmers with sports qualifications from first-class athlete to Master of Sports International Class, and separately, – between 38 males and 9 females (Masters of Sports and Masters of Sports International Class), 28 males and 16 females (Candidates for Masters of Sports), and 22 males and 17 females (first-class athletes). The results. In the general group (86 males vs. 42 females) only the greater value of PWC170/kg in males by 12.64 % (p<0.001) was revealed, without any differences in heart rate variability and central hemodynamics. Masters of Soprts and Masters of Sports International Class, as well as Candidates for Masters of Sports, didn't have gender differences in all indicators studied. In first-class athletes, there were no gender differences in heart rate variability and central hemodynamic parameters, except for PWC170/kg, which in males was greater by 11.27 % (p=0.036). Conclusions. A comparison of 86 male and 42 female swimmers with sports qualifications from first-class athlete to Master of Sports International Class, who differed by age and training experience, showed no significant differences in HRV and central hemodynamic parameters except for PWC170/kg, which was 12.64 % higher in males (p<0.001). There were no significant differences between all studied indices in 38 male and 9 female swimmers with sports qualifications Master of Sports and Master of Sports International Class, with no differences in age or training experience. Comparison of 28 male and 16 female swimmers with sports qualification Candidate for Master of Sports, not differing by age and training experience showed no significant differences in HRV and central hemodynamic parameters, except for PWC170/kg, which was greater in males by 11.27 % (p=0.034). In 22 male and 17 female swimmers with sports qualification first-class athlete, not differing by age (males have greater training experience) there were no differences between all studied indices.
