Anaerobic capacity of upper extremity muscles of male and female swimmers
Study aim: To assess the anaerobic capacity of upper extremity muscles of male and female swimmers by applying two exercise tests.
Material and methods: Male and female swimmers (n = 9 and 6, respectively), aged 19 - 23 years and having training experience of over 10 years, were subjected to two tests: 30-s Wingate for upper extremities and semitethered swimming test. The following variables were determined: body fat content (from 4 skinfolds), maximum power output, heart rate (HR) and lactate (LA) concentration in blood.
Results: Relative power outputs in the Wingate test and swimming force in semi-tethered swimming test (maximum and mean) were significantly (p<0.001) higher in male than in the female swimmers. Maximum LA concentrations were higher in male than in female swimmers, but maximum LA values related to relative power output were in both genders alike. Maximum force produced in the semi-tethered swimming test was strongly (r = 0.765; p<0.001) correlated with maximum relative power output in the Wingate test.
Conclusions: Both tests may be interchangeably applied to determine the anaerobic capacity of upper extremity muscles in swimmers.
