| 摘 要： | 运用生物力学测试手段对１０８ｋｇ以上级、国家健将级举重运动员姜凯的抓举动作进行分析，找出受试者抓举动作的主要问题是：１）在伸腿前俯和引膝提铃阶段伸腿不充分，使腿部力量没能很好地发挥出来；２）由于髋关节在引膝提铃阶段过早用力，使得伸膝范围受到限制，腰背力量不能完全发挥。并针对受试者的问题提出改进办法，已取得了一定成绩。

| Abstract: | By means of biomechanical measurement the snatch movements of Jiang Kai, the national masterweightlifter of the grade above 108 kg were analyzed. The main problems in his snatch movements werefound.,l) Owing to an insufficient leg extension in the phases of stooping down by stretching leg and bringingup by hip trust, his force of the legs could not be bought into play. 2 ) Owing to a premature effort of the hipjoint in the phase of bringing up by hip trust, the range of the extending knee was restricted, and the force ofthe waist and back couldn't be fully brought into play. Thus, methods for improving those problems were putforward, and certain results were achieved. |
