摘要:

背景:目前,国内外利用等速仪器针对铅球运动主要环节肌肉力量特征方面研究的文献较少。

目的:查找铅球运动员不同速度下各主要环节肌力配布特征和存在的不足。
方法:利用德国ISOMED2000等速肌力测试系统,对第十一届全运会男子铅球冠军膝关节、髋关节、腰背环节和肩关节进行慢速60 (°)/s和快速180 (°)/s等速测试。
结果与结论:①膝关节慢速左右侧屈伸肌比值为25.6%、39.4%,快速屈伸肌比值为28.5%、29.8%,屈肌群肌力较小。②髋关节在快、慢速时,右侧伸肌群分别为左侧的2.11和1.87倍,屈肌群为1.25和1.64倍,右髋非常显著性大于左髋。③腰背环节慢速屈伸肌比值为93.3%,快速测试屈伸肌比值为84.3%。④肩关节自然位屈伸,慢速屈伸肌力右肩分别为左肩的1.27和1.34倍,快速为左肩的1.40和1.92倍。⑤各环节根据人体模型相对质量按膝关节为基准膝、髋、躯干、肩为1∶2.38∶3.30∶0.70。结果表明:①膝关节屈伸肌群绝对肌力、快速屈肌群肌力均较弱,肌群配备不合理。②躯干肌力在右侧最大力量伸肌群、左右侧快速伸肌群非常薄弱,增加腰背肌力伸肌训练,特别是慢速和快速肌肉力量和伸展性训练。③右侧各环节伸肌群薄弱,加强右肩伸肌群的绝对肌肉力量。

Abstract:

BACKGROUND: At present, the detections of muscular strength of the main joints in shot putters by using isokinetic system are rarely reported.

OBJECTIVE: To find out the characteristics of muscular strength of the main joints in shot putters under different speed, and explore the existing shortcomings.
METHODS: Using German ISOMED2000 isokinetic test system, we detected the isokinetic muscular strength of knee joint, hip joint, waist-back segment, and shoulder joint of the men’s shot put champion in the 11th National Games, at slow 60°/s and fast 180°/s.
RESULTS AND CONCLUSION: (1) H/Q ratios of the left and right side of knee joint were 25.6%, 39.4% in slow speed, while 28.5%, 29.8% in high speed. In addition, flexor muscle group had small muscular strength. (2) The muscular strength of the right extensor group of hip joint was as much 2.11 and 1.87 times respectively as left side in high and slow speed. Meanwhile, flexor muscle group was 1.25 and 1.64 times and significance of right hip was greater than the left. (3) H/Q ratios of the waist and back joints were 93.3% and 84.3% respectively in high and low speed. (4) Under natural flexion of shoulder joint, myodynamia flexion in slow speed was as much 1.27 and 1.34 times respectively as the left, while 1.40 and 1.92 times respectively as the left in fast speed. (5) According to relative weight of the human body model, when each segment was compared to knee as a benchmark, the knees, hips, body and shoulder joints were 1:2.38:3.30:0.70. The findings indicate that, (1) in the knees joint, not only absolute myodynamia of flexor and extensor groups, but also myodynamia of fast flexor groups are weak, the equipment of myodynamia group is not reasonable as well. (2) The body myodynamia reaches the peak in the right side of extensor group, while rapid extensor myodynamia at the left and right side is very weak, therefore, we should increase the training of waist and back extensor, especially muscle strength training and extension training at the slow and high speed. (3) As extensor group on the right side is weak, we should strengthen the absolute extensor group muscle power of right shoulder and absolute muscle strength of flexion muscle group.
