Abstract

The aim of the present study was to establish the influence of muscle heating and cooling on knee flexors and extensors for males and females. Methods of the study: The participants of the study were 10 healthy male, age: 19-23 years; height – 177.8 ± 5.8; weight – 78.2 ± 6.1 and 10 female, age: 18-23 years; height – 166.4 ± 5.6; weight – 56.2 ± 6.1. The participants of the study were seated in isokinetic dynamometer. In the control panel the isokinetic regimen was selected. The type of concentric contraction is automatically established by the system exercising in this regimen. Control measuring prior to load and 10 min, 30 min, 60 min and 24 h after it (3 times of leg extension and leg flexion in the knee joint at the fixed 450°/ s speed); isokinetic load – 50 leg extensions and flexions in the knee joint at the fixed 4500/ s speed. Before and after muscles cooling or heating we measured muscles temperature with needle thermometer. Creatine kinase activity in blood serum was estimated 1 h prior to load and 24 h after it. The evaluated parameters were: peak torque (measured in N • m). Results and discussion: After individual analysis of values we have found that muscle heating or cooling before exercise didn't decrease power in max speed of knee extensors and flexors for males and females. A comparison of CK activity in the blood serum of men's and women's muscles at control temperature (1 h prior to load) and at their usual temperature 24 h after load has revealed a statistically significant difference (p < 0.05). The main conclusion: Passive muscle warming and cooling, irrespective of gender, increased neither muscle contraction power or muscle contraction force and caused no changes in the rate of muscle resistance to fatigue and their recovery after isokinetic load performing 50 leg extensions-flexions at high (450° / s) speed. Both muscle warming and muscle cooling caused a decrease in an indirect symptom of muscle damage – the amount of creatine kinase 24 h after isokinetic load. Verf.-Referat
