|
The effects of 8 week weight training, PNF training, and the complex training on the anaerobic power, and blood stress anaerobic capacity and blood stress variables were inves-tigated among 21 collegiate Taekwondo playes. Seven sub-jects were randomly assigned to each group, and under-went 8 week training programs. Each variable was meas-ured before and 4 and 8 weeks after the training. For the maximum and the average powers were analyzed for the anaerobic power. The amount of creatine phosphoki-nase(CPK) and the Cortisol hormone indicating the level of muscle damage were analyzed for the blood stress variables. There were 3 experimental groups and 3 data col-lection sessions. The anaerobic power(maximum and aver-age power) significantly increased in all the training groups after 8 weeks. There was no significant change of the blood stress factors (CPK and cortisol) in the weight training group after the training, the PNF and the combination groups showed significantly decreased CPK levels after the 8 weeks. The cortisol levels in both groups weren’t sig-nificantly different from the pre-tests.
