Abstract
Introduction: Aging is a time-dependent biological and degenerative process. The purpose of this study was to investigate the effect of Sprint Interval Training (SIT) on the oxidative-antioxidant status of the gastrocnemius muscle in aged male rats.
Methods: In this experimental study, twelve adult male rats were maintained in the laboratory environment until reaching old age (20 months) and then divided into either a control group or an SIT group. The SIT protocol lasted for eight weeks, with three sessions per week. Each session consisted of 4-6 repetitions of maximum-speed running for 10-15 seconds, with 60-90 seconds of rest between repetitions. After the intervention period, the levels of Carbonylated Protein (PC), Superoxide Dismutase (SOD) activity, and Glutathione Peroxidase (GPx) activity were measured in the gastrocnemius muscle. An independent t-test was used for data analysis at a significance level of p < 0.05.
Results The results showed a slight but non-significant decrease in carbonylated protein levels in the exercise group compared to the control group (P=0.870). SOD enzyme activity showed a non-significant 14.6% increase in the sprint interval training group (P=0.181). The change in GPx enzyme activity was also not statistically significant (P=0.953).
Conclusion: Based on the results of this study, sprint interval training with short 10-15 second repetitions did not induce significant oxidative stress in the gastrocnemius muscle of aged male rats. However, the lack of statistical significance and limitations such as sample size prevent definitive conclusions regarding the safety or efficacy of this protocol.
