Comparison of the Effect of 6 Weeks Resistance Training with and without Vascular Occlusion, on Serum Levels of CRP and LDH in Active Girls

Extreme sports are associated with immunological changes as well as changes in the indices of inflammation and muscle damage. So, the purpose of this study was to compare the effect of 6 weeks resistance training with and without vascular occlusion, on serum levels of CRP and LDH in active girls.
This study was a quasi-experimental one. 36 female students of physical education with an average aged 20.51 ±1.39 years and BMI 23.32 ± 2.79 kg/m2 were divided into three groups: resistance training without occlusion (exercise at 75% of one repetition maximum), resistance training with vascular occlusion (exercise at 30% of one repetition maximum with closing of tourniquet around the proximal arm) and the control group. Both training exercise groups performed a six-week training program consisting three sessions per week. During this period, the control group performed their daily activities. Blood samples were taken before the start of training and 24 hours after the last training session. Spectrophotometric and ELISA method was used for evaluating lactate dehydrogenise and CRP. Data were analyzed using paired sample t test, and one-way ANOVA. To compromise the results between three groups bonferroni test was used.
After 6 weeks of resistance training with and without vascular occlusion, index of muscle damage (LDH) revealed a significant increase in response to resistance training (p.05).
According to the results of the research, both types of resistance training have a positive effect on variables of inflammatory marker of muscle damage. But it seems that in vascular- occlusion group changes are more obvious.
