Abstract:
Objective Through morphometric methods,the effects of soy hydrolyzed peptides(SHPs) supplementation on histological and ultrastructural damages of skeletal muscle after intensive training were investigated.Methods 150 male Sprague-Dawley rats were randomly divided into 15 groups according to different supplementations(placebo,ISP and SHPs),exercise or not and different sampling phase after exercise.Rats in exercise groups ran 120 minutes at speed of 20?1m /min and-16? of slope.All rats were respectively fed with 2ml beverage containing 15% SHPs,15% ISP or placebo for 1 week before exercise.Results HE staining results showed that the skeletal muscle structure changed obviously in 24～48hr after exercise and the ultrastructure of skeletal muscle changed evidently in 12～24hr after exercise.With ISP or SHPs supplementation,the histological and ultrastructural damages of skeletal muscle reduced obviously.Moreover,SHPs supplementation showed better protective effects than ISP supplementation.
