【摘要】：研究目的:本研究旨在通过探讨两种不同末端释放训练方法对于排球专业运动员下肢力量训练的比较,探讨其对排球运动员下肢爆发力及原地拦网起跳能力的效果研究。研究方法:本研究选取北京体育大学男子排球队14名优秀运动员,进行为期8周的力量训练,每周训练2次。所有运动员被随机分为两组,实验组和传统组。实验组进行6组30%1RM的负重蹲跳结合Cormax末端释放训练器及不连续性原地拦网跳练习,每组重复6次;传统组进行6组30%1RM的传统负重蹲跳及不连续性原地拦网跳练习,每组重复6次。采用Tendo Unit爆发力和速度反馈系统分别测得负重20kg、30kg、40kg和50kg半蹲跳的输出功率和动作速度;采用Kistler三维测力台测得三种不同起跳形式半蹲跳、下蹲跳及原地拦网跳的高度;采用Smartspeed红外激光测速仪测得拦网起跳反应时间。使用SPSS17.0统计学软件对测得数据进行独立样本T检验和配对T检验分析。研究结果:(1)实验组负重蹲跳输出功率和动作速度均低于传统组;两种训练方式的输出功率随负荷的增加而不断提高,呈上升趋势;动作速度随负荷的递减而不断提高,亦成上升趋势。(2)实验后实验组右腿下蹲跳成绩(0.174±0.059m,P0.05)显著高于实验前,相较于实验前增加了0.052m。实验组和传统组双腿下蹲跳和原地拦网跳成绩均有提高。两组实验后双腿半蹲跳成绩均有下降。(3)实验后两组拦网起跳反应时间均缩短,实验组反应时间缩短了0.068±0.089秒,传统组反应时间缩短了0.047±0.084秒。研究结论:(1)在同等负重下,无离心收缩阶段的末端释放蹲跳训练输出功率和动作速度均小于传统负重蹲跳。(2)两种末端释放训练方法都可以提高排球运动员比赛恢复期纵跳成绩,而无离心收缩形式的末端释放训练能够更有效提高排球运动员下蹲跳成绩。(3)末端释放训练方法虽然未能显著提高运动员原地拦网起跳高度,但排球场地移动拦网起跳反应时间均明显缩短。
[Abstract]:Objective: the purpose of this study was to study the effects of two different terminal release training methods on the lower limb strength training of volleyball professional athletes and their ability to take off in situ blocking nets.Methods: in this study, 14 elite men's volleyball players from Beijing University of physical Education were selected for 8 weeks of strength training, twice a week.All athletes were randomly divided into two groups, experimental group and traditional group.In the experimental group, the weight bearing squat jump of 30%1RM was combined with the Cormax terminal release training device and the discontinuous in-situ block jump exercise, which was repeated 6 times in each group, while the traditional group of six groups of 30%1RM were performed the traditional weight-bearing squat jump and the discontinuous in-situ block jump exercise.Repeat 6 times in each group.The output power and the action speed of the weight bearing 20kg / 30kg / 40kg and 50kg's half squat jump were measured by Tendo Unit explosive force and velocity feedback system respectively, and the height of the three different take-off forms, the squat jump and the in-situ blocking jump were measured by using the Kistler three-dimensional force measuring platform.The reaction time was measured by Smartspeed infrared laser velocimeter.SPSS17.0 statistical software was used to carry out independent T test and paired T test analysis of the measured data.The results showed that the output power and action speed of the experimental group were lower than those of the traditional group; the output power of the two training methods increased with the increase of the load, and the speed of the action increased with the decrease of the load.After the experiment, the score of the right leg squat jump in the experimental group was 0.174 卤0.059mP0.05) significantly higher than that before the experiment, and increased by 0.052mcompared with that before the experiment.In both experimental and traditional groups, the scores of squatting jump and in situ blocking jump were improved.After the experiment, the reaction time of the two groups was shortened, the reaction time of the experimental group was shortened by 0.068 卤0.089 seconds, and the reaction time of the traditional group was shortened by 0.047 卤0.084 seconds.Conclusion: under the same load, the output power and action speed of the end release squat jump training in the stage of no centrifugal contraction are lower than that of the traditional weight bearing squat jump. 2) both of the two end release training methods can improve the result of the vertical jump in the recovery period of the volleyball players.However, the end release training without centrifugal contraction can effectively improve the score of squat jump. 3) although the training method of terminal release can not significantly improve the take-off height of the athletes,However, the reaction time was shortened obviously.
