The Antioxidant Enzymes Activities in Blood of Physical Education Students after Eccentric and Concentric Training Activities

Physical activity is well known to induce free radicals and reactive oxygen species (ROS). There are enzymatic and non-enzymatic defense systems against ROS in aerobic organisms. The aim of this study was to investigate the acute effect of eccentric and concentric training on activities of the antioxidant enzymes in physical education student's blood samples. Twenty four females students volunteers participated in the study who were randomly assigned to three groups: control (age 20.52 ± 0.18 year, BMI 21.15 ± 0.43 kg/m ), eccentric 2 training group (age 21.37±0.49 year, BMI 20.82±0.49 kg/m ) and concentric training group (age 20.66±0.36 year, 2 BMI 21.46±0.58 kg/m ). Blood samples, collected 1h before and immediately after training and analyzed for 2 activities of the antioxidant enzymes, glutathione peroxides (GPx), glutathione educates (GR). The results shows no significant differences were found in GR activities between the groups. There was an significant (p<0.05) increase in GPx activities compared to control group (p<0.05). However after concentric training, an significant (p<0.05) increase was observed in GPx activities compared to before training and total Hb levels increase after training compared with before training. In conclusion may the eccentric and concentric training show an improved in blood antioxidant enzyme activities.
