Effect of Intensity and Volume of Exercise Training on Serum Levels of Ceruloplasmin and Malondialdehyde in Elite Handball Player Girls

Imbalance between the production of free radicals and the antioxidant defense system leads to oxidative stress. The purpose of this study was to investigate the effect of four weeks of high intensity interval training (HIIT) versus four weeks of aerobic training on serum levels of ceruloplasmin and malondialdehyde in elite handball player girls.

Thirty young handball player girls (mean aged 16.85±1.4 years), with four years of membership in handball team of North Khorasan province, were selected and randomly divided into two groups of training and one control group. Subjects in experimental groups participated in four weeks of HIIT [running at intensity of 95-90 percentage of maximum heart rate and resting intervals of 1-3 minutes running at 60-50 percentage of maximum heart rate] and aerobic training (running at 50-70 percentage of maximum heart rate, 45-60 minutes per session), three sessions per week. The blood samples were taken factors before and 48 hours after last training session to assess blood factors. Data analysis was done by One-way ANOVA, paired t-test, and Pearson correlation, and P<0.05 considered significant.

Serum levels of MDA decreased significantly following aerobic training (P=0.044). Moreover, weight (P=0.009), body mass index (BMI) (P=0.002) and body fat percent (P=0.036) decreased significantly following HIIT. Furthermore, aerobic training resulted in significant decline in weight (P=0.008), BMI (P=0.015) and body fat percent (P=0.013).

It seems that the volume of training influences on serum levels of MDA; however, ceruloplasmin levels was affected by neither intensity nor volume of training.
