Background and Objectives: The effect of physical activity and training stress on the body's oxidative and antioxidative systems and consequently on the athlete’s performance is one of the topics that have been considered by exercise physiologists. The aim of the present study was to investigate the effect of six weeks of aerobic training plus grapefruit juice on serum MDA and SOD levels in young girls.
Methods: For this purpose, thirty young girls (weight: 55.46 kg, height: 1.63 m and BMI=20.84 kg / m2) voluntarily participated in this study and randomly divided into three groups (aerobic training group (n=10), grapefruit juice consumption group (n=10) and grapefruit juice + aerobic training group (n=10)). aerobic training groups were exercised for 6 weeks, 3 times a week and 60 minutes a day. training program in each session was consisted of general warm-up (10 minutes) and continuous running for 40 minutes (50-70%HRR) and cool down (10 minutes). Grapefruit juice Groups received five ml/kg of grapefruit juice (for six weeks and three times a week) 20 mins before exercise. Blood samples were collected 24hrs before first and after last session of exercise training to measure SOD and MDA. Data were analyzed by using paired-sample T-test and ANOVA.
Findings: The results showed that Six weeks of aerobic exercise with grapefruit juice consumption have no significant effect on serum MDA and SOD levels (P≥0/05). However, the results of paired T- test indicated a significant difference in pre and post-test SOD levels in training+ grapefruit juice group (P=0/033).
Conclusion: According to the results of this study, training protocol with grapefruit juice consumption could not have significant effect on MDA and SOD indices. However, it is likely that aerobic training and grapefruit juice may improve antioxidant conditions and reduce the factors contributing to cellular damage.
