Oxidative stress biomarker response to concurrent strength and endurance training.
The purpose of this study was to investigate the effects of concurrent training on oxidative stress biomarkers in judokas, as well as to compare the effects of such training on performance characteristics in relation to usual training programs. A total number of 14 male judokas were divided into two groups: experimental (E) and control (C). Over 12 weeks, subjects from E group were included into specially designed training composed of concurrent strength and endurance training and perfecting of specific judo techniques. Subjects from C group were included into the same strength training and perfecting of specific judo techniques, but did not have any endurance training. The investigation protocol consisted of Wingate test for the upper extremities, estimation of maximum oxygen uptake, the assessment of body composition, special judo fitness test and determination of selected markers of oxidative stress. The results obtained suggest that usual training program pattern had no effects on oxidative stress levels in C group subjects, while concurrently performed training for strength and endurance induces the increases in anaerobic power and maximal oxygen uptake, but also affects oxidative stress biomarkers. A significant increase in erythrocyte malondialdehyde and plasma catalase can be considered negative effects of this training program.
