Abstract

Background and Objectives: The aim of this study was to investigate effects of eight weeks of High intensity interval training (HIIT) on Myostatin (MSTN) and Follistatin (FLST) expression in fast and slow twitch muscles of Wistar rats. Methods: First, 12 male 8-week old male Wistar rats were randomly divided into two groups of exercise (n=6) and control (n=6). The exercise group performed progressive HIIT, five times a week for eight weeks. The training protocol included alternating sprint running for 30 min/session, divided into three 4-min bouts (35-50 m/min, >90% VO2 max) separated by a 2-min active recovery period (30-50% VO2 max). The level of MSTN and FLST expression in soleus (SOL) and extensor digitorum longus (EDL) muscles were measured by real-time RT-PCR. Results: Following HIIT, MSTN level decreased significantly in the SOL muscle and increased significantly in the EDL muscle (P<0. 001). Moreover, FLST expression increased significantly both in the SOL and EDL muscles (P<0. 001). Conclusion: Based on the results, eight weeks of HIIT can significantly inhibit MSTN expression and increase FLST expression in fast and slow twitch muscles.
