【摘要】 <正> 一、引言一九八五年四月十七日在杭州举行的第十七届亚洲举重锦标赛75公斤级挺举比赛上,我国优秀运动员廖继光在第二次试举中成功地举起了185公斤,打破了当时的全国记录。在第三次试举中,廖继光试举190公斤向亚洲记录冲击。但是在完成上挺动作时,上肢将杠铃举过头顶之后,由于下肢没能支撑住,致使动作失败。是什么原因造成下肢支撑不住呢?在廖继光采用的半蹲式接铃技术中,下蹲动作应如何完成?本文的目的就是通过对廖继光上述两次试举的生物力学分析,更多还原

【Abstract】 The following conclusions were drawn from a biomechanical analysis of Liao Jiguang’s jerk technique: 1. Judging from the height to which the barbell was lifted and the result of computer simulation, Liao is capable of jerking 190 kg. 2. Liao’s failure in attempting a 190-kg jerk was mainly due to his excessive attention to the action of his upper limbs when he jerked, which pre-vented him from bringing his lower limbs into full play. As a result, his leg extension was too slow and inadequate for a successful jerk. 3. The squat jerk calls for a timely execution of the second leg extension and the completion of the stand-up action without any pause. This is themain feature distinguishing it from the split style.更多还原
