Abstract
Resistance exercise is associated with increased oxidative stress. However, it is not completely obvious how resistance training intensity can affect the rest levels of oxidative stress indexes. Therefore, the aim of the present research was to study the effect of moderate resistance (MR) and high resistance (HR) training on oxidative stress. 20 males (age: 20.6±0.7 yr, height: 1.74±0.06 m, weight: 71.1±4 kg) voluntarily participated in the research and were randomly assigned to one of the HR and MR groups. Blood samples were collected before and after the training program and activities of creatine kinase (CK), malondialdehyde (MDA) and total antioxidant capacity (TAC) were measured. The training program was performed for eight weeks, three sessions per week. HR and MR subjects performed the training with 85-90% and 65-70% of one repetition maximum (1RM) respectively. The results showed no significant difference in CK, TAC and MDA in the interaction of group and time of two resistance training protocols (P≥0.05). However, both MR and HR groups decreased MDA significantly after the training (P≤0.05). But there were no significant changes in CK and TAC compared with the pretest (P≥0.05). It can be concluded that both MR and HR training can decrease MDA and oxidative stress. It seems that this decrease is separate from the intensity of the training.
