Material and methods: Sixteen male Wistar rats (22-day, 60 ± 63 g) after one week of familiarization, were divided randomly into control and HIIT groups. Training protocol included 4 weeks (6 sessions/w) of treadmill running. HIIT protocol included one-minute of intervals with the specified speed and 2-3 minutes active rest between the intervals. Running speed was started with 16-22 m/min at the first week, and reached to 36-40 m/min at the last week. Forty-eight h after the last training session, performance was measured by the exhaustive endurance test. Animals were sacrificed 24 h after the end of the performance test. The liver tissue was removed and feezed at -80 ◦C. Malondialdehyde (MDA) and Total antioxidant capacity (TAC) levels were measured by Randox kit (England). Data were analyzed using Independent-sample T-test. The statistical significance was set at p≤0.05.
Results: HIIT group showed a non-significant decrease (46%) in the MDA level compared to the control group (P= 0.077). Also, there were no statistical differences in liver TAC levels among groups (P= 0.938).
Conclusion: HIIT may reduce oxidative stress in liver tissue during adolescence period. So, it can be administered for immature athletes. However, more research is needed in this area.
