摘　　要：背景:振动训练作为一种新兴的肌肉力量训练方法,在国外众多领域得到广泛开展。足球作为下肢引导类运动项目之一,对下肢力量素质提出了更高的要求。目的:通过对比分析振动训练和传统力量训练对足球运动员膝关节屈伸肌群肌肉力量的作用,探讨振动训练对足球运动员力量训练的意义。方法:将20名大学生男性足球运动员随机分为2组,每组10人。振动组采用连续8周、30 Hz频率、2 mm振幅的振动训练,对照组采用无振动的传统下肢力量训练。训练前后分别在60 (°)/s和180 (°)/s角速度下对运动员膝关节屈、伸肌群峰力矩、到达峰力矩的时间及总功进行测试。结果与结论:①训练后2组在60,180 (°)/s角速度下峰值力矩均显著升高(P <0.05),在60 (°)/s角速度下2组组间比较峰值力矩差异显著(P <0.05),180 (°)/s角速度下组间峰值力矩比较无显著差异(P> 0.05);②在180 (°)/s角速度下与训练前比较,2组到达峰值力矩时间显著降低(P <0.05),组间比较无显著差异(P>0.05);③在60,180 (°)/s角速度下2组总功训练后显著升高(P <0.05),振动组屈、伸肌总功显著大于对照组(P <0.05);④结果说明,采用连续8周、30 Hz频率、2 mm振幅的振动训练方案可有效提高大学生足球运动员膝关节屈、伸肌最大力量、爆发力和肌肉耐力;在提高最大力量和肌肉耐力方面,振动训练优于传统力量训练;在提高肌肉爆发力上,振动训练与传统力量训练相比未见明显优势。BACKGROUND:Vibration training,as a new emerging method for muscular strength training,has been extensively applied in various fields at abroad.Football is a kind of exercise of guiding lower extremity,so it requires high quality of low limb strength.OBJECTIVE:To compare and analyze the effects of vibration training and traditional strength training on the strength of knee flexors and extensors of football players,and to explore the significance of vibration training on the strength training of football players.METHODS:Twenty college football players were randomly divided into vibration and control groups(n=10 per group).The vibration group received vibration training(30 Hz,2 mm,8 weeks),and the control group received traditional training of lower limb strength without vibration.The peak torque,time to peak torque and total work of knee flexors and extensors were measured before and after training at 60 and 180(°)/s angular speeds.RESULTS AND CONCLUSION:(1)The peak torque at 60 and 180(°)/s angular speeds in the two groups was increased significantly after training(P<0.05).There was significant difference between two groups at 60(°)/s angular speeds(P<0.05),but there was no significant difference between two groups at 180(°)/s angular speeds(P >0.05).(2)The time to peak torque at 180(°)/s angular speeds in the two groups was decreased significantly after training(P<0.05),but there was no significant difference between two groups(P >0.05).(3)The total work at 60 and 180(°)/s angular speeds in the two groups was increased significantly after training(P<0.05).The total work of flexors and extensors in the vibration group was significantly higher than that in the control group(P<0.05).(4)These findings indicate that vibration training program of 8 weeks,30 Hz frequency and 2 mm amplitude can effectively improve the maximum strength,explosive force and muscle endurance of knee flexor and extensor of college football players.Vibration training is superior to traditional strength training in terms of maximum streng
