Tenisçilerde Orta ve Yüksek Şiddetteki Antrenmanın Oksidatif Stres ve Bazı Antioksidan Aktiviteler Üzerine Etkisi

Abstract

The aim of this study is to examine the effects that moderate and high intensity training has on oxidative stress and some antioxidant activities in tennis players. A total of 31 volunteers, 15 active tennis players and 16 healthy individuals who did not play sports, aged between 18-26, with no reported health problems and who did not take external antioxidant supplements, participated in the study. Each group was given light jogging, warm-up and gymnastic exercises and technique training. Afterwards, the athletes had a training match. In the research, to determine oxidative stress and some antioxidant activities, blood samples were taken from both groups before and after the training. Serum MDA and GSH levels and CAT, SOD and GPx activities were measured using spectrophotometric methods. The data distribution was checked. The Paired samples t-test statistical analysis was used for the data not showing normal distribution and Wilcoxon test statistical analysis is used for data with normal distribution. In the research findings, during the warmup, it was determined that the MDA values increased for both groups, while the SOD, CAT and GSH values were found to decrease significantly (p<0.05). Pre-exercise MDA and GSH values of the experimental group were found to be low when compared to the control group, while SOD and CAT values were found to be high (p<0.05). As a result, it can be said that moderate and high intensity training in tennis players causes oxidative stress and negatively affects antioxidant capacity.
