Abstract

Objective To explore the influence of different swimming exercises on c-fos expression in rat's dentate gyrus.MethodsFifty-five Sprague-Dawley male rats were randomly divided into control group(group A,n=5),endurance swimming group(group B,n=25),interval swimming group(group C,n=25).The rats in groups B and C were trained by different types of swimming for 6 weeks.The brains were removed at 0,0.5,1,2,4 h after the last swimming exercise.Immunohistochemistry was used to detect c-fos expression in rat's DG.ResultsThe expression of c-fos in groups B and C increased significantly at each time point compared with group A(P0.05).The expression of c-fos peaked at 0.5 h in group B while at 2 h in group C.There was significant difference at each time point between groups B and C(P0.05).ConclusionThe expression of c-fos may be influenced by different swimming exercises.
