This study was to investigate the effect of swimming exercise in temperature difference on the expression of PGC-1α, Tfam, Mfn2 and irisin in skeletal muscles of the obese-induced rats by high fat diet.
Forty eight SD rats were assigned to 8weeks of ND and HFD. Thereafter, each group of the rats was divided into eight different groups: NC, NLE, NME, NHE, HC, HLE, HME, HHE. The exercise was accomplished by swimming the rats at 22˚C, 28˚C and 36˚C for 1hour/day, 5times/week during 8weeks. The expression of PGC-1α, Mfn2 and irisin in skeletal muscle(soleus) were examined by the Western blotting.
The weight of obese-induced rats was reduced by swimming exercise. The expression of PGC-1α and Mfn2 were significantly increased in all of swimming exercise group than non-exercise group(NC and HC), especially higher in NLE. The expression of irisin was increased other group excepting NHE and HLE. But the expression of PGC-1α, Mfn2 and irisin following obesity were no changed.
Therefore, it was concluded that swimming was helpful for improvement of exercise ability and a loss in weight because it made mitochondria of skeletal muscles improve and fat consumption stimulate. Especially, swimming in low temperature increased these effectiveness.
