| 摘 要： | 运用三维运动学的研究方法,对参加2005年全国第十届体育运动会举重比赛的运动员石智勇的抓举技术进行运动学分析。结果表明,提铃过程中人杠重心间距控制合理,杠铃平均加速度超过2 m/s2,体现了优异的爆发力和出色的提铃技术;引膝阶段的技术与常规引膝技术已有了很大的改变,该阶段用时很短,膝关节角度也几乎没产生变化,通过对膝关节的制动充分发挥了腰背部肌肉力量,使抓举时杠铃最高加速度的值出现在引膝阶段而非发力阶段,这是最体现石智勇抓举技术特点的地方;抓举发力阶段,身体用力协调,各关节角度的把握也恰到好处;抓举下蹲支撑阶段技术动作堪称完美,人杠重心间距控制合理,杠铃回落距离仅为13.6 cm,人体重心向下的平均加速度为11.2 m/s2,两项均属于世界顶级选手的技术指标;在起立阶很好地利用了杠铃的弹性势能,与杠铃同步起立,同时人杠重心间距仅为0.002 m,确保了起立的稳定性。 |

| Abstract: | With the methods of 3D kinematic analysis,this paper made an analysis on Shi zhiyong's snatch technique in weightlifting competition of the Tenth National Games.The results showed that the gravity distance between Shi and the bar was reasonable in the barbell lifting and the average acceleration was over 2m/s2,which reflected the excellence of explosive power and barbell lifting skill.His knee movement technique changed greatly,the movement time being very short and the angle of knee joint almost had no cha... |
