High-intensity interval training increases thermogenesis and metabolism through changes in regulatory proteins

Abstract

The present study aimed to investigate the effect of 4 weeks of high-intensity interval training on the amounts of metabolic proteins like Sarcolipine, PGC1α and FNDC5 in SOL and EDL muscles of male Wistar rats. In the present study, 14 adult male Wistar rats were randomly divided into experimental (n = 7) and control (n = 7) groups. The training group performed high-intensity interval training for 4 weeks and 5 sessions per week, including high-intensity (90% vVO2max) and low-intensity (45% vVO2max) two-minute intervals. Finally, the SOL and EDL muscles of the research groups were extracted, and also independent statistical t-test (p <0.05) was used for statistical analysis. The results showed that the amounts of SLN, PGC1α, and FNDC5 proteins in the experimental group were significantly different from the control group in SOL muscle, but the amounts of FNDC5 protein in the EDL muscle of the HIIT group were not significantly different from the control group. The results showed that by observing the changes in the amounts of regulatory proteins related to cellular metabolism due to high-intensity interval training, this training method could be suggested to increase metabolism and improve the lipid oxidation process in a short time.
