Abstract
Background and Aim: The aim of this study was to investigate the effect of eight weeks endurance training at different durations on plasma heat shock protein 27 in male rats. Materials and Methods: Forty adult Wistar male rats (eight weeks old, 189 ± 10g weight) were used for this study. Animals were divided into 4 groups including control, 30 min/session training, 60 min/session, and 90 min/session training groups. The training was included of treadmill exercise at 20 m/min (0% grade) in five days/week for eight weeks. Subjects were sacrificed 72 h after the last session of exercise for measurement of heat shock protein 27 levels in the plasma. Heat shock protein 27 content in the plasma was determined with EIA kit and ELISA system data were analyzed using one-way ANOVA and LSD at P≤0/05. Results: Findings showed that plasma concentrations of heat shock protein 27 were significantly (P < 0.05) higher in 60 min/session training group. Conclusion: This study show that chronic mild-duration exercise could yield to greater levels in heat shock protein 27 plasma concentrations compared to the less or more durations.
