【摘要】：对田径运动员强度训练与心肌损伤关系建模,可以将运动损伤降低到最低点,是实现现代体育竞技的重要前提。进行强度训练与心肌损伤关系建模时,需要提取心肌功能相关的8项生化指标,并利用运动员在强度训练时各个指标状态间的关联性建立强度田径运动员强度训练与心肌损伤关系模型,而传统方法只是获取运动员在训练前后的肌酸激酶变化一个指标,利用上述指标进行关系建模,存在建模误差大的问题。提出基于改进条件概率约束的田径运动员强度训练与心肌损伤关系优化建模方法。先依据稀疏特征表达算法建立运田径运动员强度训练时的生化生理机制模型,提取运动员在训练对肌肉收缩的能源供应的磷酸原供能和糖酵解供能的变化特征,得到田径运动员强度训练后与心肌功能相关的8项生化指标,依据对8项指标性能指标关系的测度和运动员在大强度训练时各个指标状态间的关联性建立了精确的田径运动员强度训练与心肌损伤关系模型。仿真结果证明,田径运动员强度训练与心肌损伤优化建模可以为运动员优化训练提供科学依据。
[Abstract]:Modeling the relationship between intensity training and myocardial injury of track and field athletes can reduce the sports injury to the lowest point, which is an important prerequisite for the realization of modern sports. Eight biochemical indexes related to myocardial function should be extracted, and the relationship between intensity training and myocardial injury of athletes should be established by using the correlation between each index state during intensity training. The traditional method is only to obtain an indicator of the changes of creatine kinase before and after training, and use the above indexes to model the relationship. This paper presents an optimal modeling method for the relationship between strength training and myocardial injury of track and field athletes based on the improved conditional probability constraint. Firstly, the intensity training of track and field athletes is established based on sparse feature expression algorithm. Model of biochemical physiological mechanism, The changes of energy supply of phosphate and glycolytic energy supply to muscle contraction were extracted, and 8 biochemical indexes related to myocardial function of track and field athletes were obtained after intensity training. Based on the measurement of the relationship between the performance indexes of the eight indexes and the relationship between the state of each index during the heavy intensity training, a precise model of the relationship between the intensity training of track and field athletes and the myocardial injury is established. The simulation results show that, Intensity training and myocardial injury optimization modeling of track and field athletes can provide scientific basis for athletes' optimal training.
