Abstract:
It was well known that the damage of skeletal muscle occurred and exercise performance declined after one prolonged eccentric exercise.But there were few studies on the adaptation to the continuous eccentric exercise in skeletal muscle.The purpose of this study was to investigate the effects of downhill running once(group B) and for one week(group C ) on α-actin gene expression of rat gastrocnemius muscle.Serum CK and LDH were determined, too.The results showed that the training had obvious effects on α-actin gene expression of rat gastrocnemius muscle in group B and C.In group B, serum CK and LDH recovered obviously 7 days after training, but not to the normal value.In group C, it recovered to the normal.These results suggest that the recovery of the damage after first training had been accelerated by the continuous eccentric exercise, the subjects gradually adapted to exercise.
