紧身针织服对田径运动员下肢肌肉活动的影响

Effect of tight knit suit on lower limb muscle activity of athletes

为促进田径运动员更好发挥身体机能,提高田径项目的赛事成绩,通过分析紧身针织服对田径运动员下肢肌肉活动受力关系模型,从运动服装的改良和优化设计方面,提出一种基于多模旋转自由度运动学分解的田径运动员下肢肌肉活动力学分析模型.首先构建紧身针织服对田径运动员下肢肌肉运动学关系模型,进行田径运动员下肢7个自由度肌肉活动空间重构.然后分析紧身针织服对田径运动员下肢肌肉活动的力学模型,实现力学关系模型改进.仿真结果表明,采用该模型进行紧身针织服对田径运动员下肢肌肉活动影响受力行为特征分析,能准确反映运动员下肢肌肉活动特征,有效提高田径运动员的运动效果和成绩.

In order to promote athletes function of the body and improve their competition per- formance, through the analysis of tight knitted clothing for track and field athletes lower ex- tremity muscle activity force relation model, from sportswear for improving and optimizing de- sign, a lower limb muscle activity mechanics analysis model is put foward based on multimode rotational degrees of freedom kinematic decomposition. First of all a tight knitted clothing for athletes muscles of the lower limb kinematics model is bulk, athletes lower limbs seven freedom muscle activity spaces are reconstructied, the mechanical model is analyzed, and the mechanics model is achieved. Simulation results show that using the model to conduct influence force be- havior analysis can accurately reflect the characteristics of athletes lower limb muscle activity~ through tight knit wear design optimization, the athlete＇s movement effect and performance can be improved.
