目的 :探讨渐进力量训练是否对上肢肌力、体成分、围度产生影响.方法 :45名健康男性大学生随机分为最大力量组、速度力量组和力量耐力组 ,进行为期6周的上肢力量训练 ,第3周调整训练量.每周练习2次 ,每次进行9~12组练习 ,练习时间约为30~45 min ;训练前、后进行上肢的形态测试、1 RM 测试和采用Lunar prodigy 双能X线对上肢体成分测试 ,同时采用GT3X+加速度计对受试者进行膳食和体力活动量的调查.结果 :1)训练前 ,各组受试者的年龄、身高、体重、BM I不存在组间差异 ;2 )训练前、后的膳食摄入量不存在差异 ,体力活动水平不存在差异 ;3)通过6周的训练 ,速度力量组和力量耐力组的上臂紧张围出现增长(P<0 .05) ,3组受试者的前臂围出现增长(P<0 .05);速度力量组、力量耐力组上肢的 LM 出现增长( P<0 .05 )、上肢体脂率出现下降( P< 0 .05 ) ,力量耐力组的 FM 出现下降(P<0 .05);3组受试者的上肢肌力、相对力量均出现增长(P<0 .05);4)速度力量组和力量耐力组的LM 提高幅度大于最大力量组( P< 0 .05 ) ,最大力量组和速度力量组的肌力和相对力量的提高幅度要大于力量耐力组(P< 0 .05).结论 :3种训练负荷都能提高上肢力量 ,最大力量组提高上肢肌力较其他组明显 ,速度力量组提高 LM 较其他组明显 ,而力量耐力组减脂作用较明显.

Objective :To explore the effects of progressive resistance training on strength ,com-position and girth of arm .Method :45 healthy 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 mi-nutes per session .The body composition of arm was assessed by dual energy x-ray absorptiom-etry ,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+ accelerome-ter .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 in-creased ( 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 .
