  • Objective:To explore the effects of progressive resistance training on strength,composition and girth of arm.Method:45healthy male college students were randomly divided into three groups:maximum power group(MG,n=15),speed-strength group(SG,n=15)and power endurance group(EG,n=15).Progressive resistance training was performed for six weeks,twice a week,each time was 9-12 group practice,practice time was about 30-45 minutes per session.The body composition of arm was assessed by dual energy x-ray absorptiometry,muscular strength was evaluated using a 1-repetition-maximum test.The dietary intake and physical activity energy were assessed by 24-hour dietary recalls and GT3X+ accelerometer.Result:1)Before training,age,height,weight,BMI is not differences between groups;2)Compared with baseline,the dietary intake and the level of physical activity were no difference.3)By six weeks of training,the forearm circumference during contraction of SG and EG increased(P<0.05);forearm circumference of three groups had increased(P<0.05);The LM of SG and EG had increased significantly,fat percent decreased(P<0.05),fat mass of EG decreased(P<0.05);the strength and the relative strength of three groups increased(P<0.05).4)The LM's increased amplitude of SG and EG was greater than MG(P<0.05,the strength and the relative strength's increased amplitude of MG and SG was greater than EG.Conclusion:Three kinds of training can increase arm strength,MG's increased amplitude is greater than other groups,LM's increased amplitude of SG is greater than other group,fat loss amplitude of EG is obvious.
