【摘要】：目的:通过对比穿加压设计举重服、普通举重服和普通举重服佩戴腰带,来证明加压举重服能否在不违反比赛规则的前提下来增强脊柱稳定性、提高举重运动员的力量输出以及力量恢复的速度。方法:受试者选取10名高水平男子举重运动员,令其随机穿着3种测试举重装备进行85%1RM的连续抓举,利用红外光点捕捉系统和三维测力台进行数据同步采集,测得躯干偏移程度及下肢各关节三维角度来评价脊柱稳定性;通过内部和外部两个方面的力量表现来评价抓举时力量输出及恢复情况。运用重复测量双因素分析法确定不同举重装备和测试首末次对脊柱稳定性、力量输出及恢复的影响。结果:在力量输出外部表现上,加压举重服抓举总时间最短,普通举重服最长;前后、左右方向地面反作用力峰值和均值、地面反作用力冲量在穿着加压举重服时最低,而垂直地面反作用力峰值和均值在穿着加压举重服时最高;抓举发力阶段杠铃举起速度均值加压举重服最低,加速度峰值最高。在力量输出内部表现上,髋关节伸展力矩、膝关节内收力矩峰值在穿着加压举重服时最小;不同举重装备没有对下肢髋、膝、踝关节功率峰值及均值产生显著影响。在脊柱稳定性上,穿着加压举重服时躯干旋转峰值最小;穿着加压举重服时髋关节屈曲峰值明显大于普通举重服、内收外展角度峰值明显小于普通举重服。不同举重装备和测试首末次在所有指标上均未出现交互作用。结论:1、加压举重服更有利于举重运动员的力量输出;2、加压举重服相比举重腰带更有利于脊柱稳定;3、无法证明加压举重服更有利于举重运动员的力量恢复。
[Abstract]:Objective: to compare the wearing of weightlifting clothing with compression design, ordinary weightlifting suit and belt to prove whether the weightlifting suit can enhance spinal stability without violating the rules of the competition. Increases the speed of strength output and strength recovery of weightlifters. Methods: ten high level male weightlifters were selected to wear 3 kinds of test equipment to carry on 85%1RM continuous snatch. The data were collected synchronously by infrared spot capture system and three dimensional force measuring table. The degree of trunk deviation and three dimensional angles of lower extremity joints were measured to evaluate the stability of spine, and the power output and recovery of snatch were evaluated by internal and external strength performance. The effects of different weightlifting equipment and the first and last test on spinal stability, strength output and recovery were determined by double factor analysis of repeated measurement. Results: in the external performance of power output, the total time of snatch of pressurized weightlifting clothing was the shortest, that of ordinary weightlifting suit was the longest, and the peak and mean of ground reaction force in front and right direction, the impulse of ground reaction force was the lowest when wearing pressurized weightlifting suit. The peak value and mean value of vertical ground reaction force were the highest in wearing pressurized weightlifting clothes, while the barbell lifting speed average in the snatch stage was the lowest, and the acceleration peak value was the highest. In the internal performance of the strength output, the hip joint extension torque and the knee joint adductive moment peak value were the minimum in wearing the pressure weightlifting clothing; the different weightlifting equipment had no significant influence on the lower extremity hip, knee and ankle joint power peak and mean value. In terms of spine stability, the peak value of trunk rotation was the smallest when wearing pressurized weightlifting clothing, and the peak value of hip joint flexion was significantly larger than that of ordinary weightlifting suit, and the peak value of abduction angle was obviously lower than that of ordinary weightlifting suit. No interaction was found in all indicators of the first and last test of different weightlifting equipment. Conclusion: 1, pressurized weightlifting suit is more conducive to the strength output of weightlifters; 2, the weight lifting belt is more conducive to the stability of the spine; 3, it can not be proved that pressurized weightlifting suits are more conducive to the strength recovery of weightlifters.
