Abstract [eng] The aim of the present study was to establish the infl uence of concentric contraction on muscle fatigue and muscle damage depending on temperature and gender. The participants of the study were 10 healthy males, aged 19—23 years; height — 177.8 ± 5.8; weight — 78.2 ± 6.1; body fat — 7,5% (body fat mass — 5.6 kg) and 10 females, aged 18—23 years; height — 166.4 ± 5.6; weight — 56.2 ± 6.1; bodyfat — 17% (body fat mass — 10.7 kg). The participants of the study were tested on isokinetic dynamometer (Biodex Medical System PRO 3). The type of concentric contraction was automatically established by the system exercising in isokinetic regimen. Control measuring (3 times of leg extension and leg fl exion in the knee joint at the fi xed speed of 180º / s) was performed before the load, after 10 min, 30 min, 60 min and 24 h after the load; concentric load — 50 leg extensions and fl exions in the knee joint at the fi xed speed of 180º / s. Before and after muscle cooling or heating and after physical load we measured muscle temperature with needle thermometer (Ellab A / S, tipe DM 852, Denmark). Creatine kinase activity in blood serum was estimated 1 hour prior to load and 24 hours after it. Muscle pain was estimated subjectively using a 10-point scale after 24 hours after the load. The evaluated parameter was the peak torque (measured in N•m). There was a signifi cant increase (p < 0.05) in creatine kinase (CK) activity in the blood serum of both men and women after 24 hours after concentric load, compared to the control value, when the muscle was at its usual temperature, as well as after warming and cooling. A comparison of CK activity in the blood serum of men’s and women’s muscles at control temperature (1 hour prior to the load) and at their usual temperature after 24 hours after the load revealed a statistically signifi cant difference (p < 0.05).[...].
