摘　　要：随着体育事业的发展,传统体育项目越来越受重视.作为我国传统体育运动的重要组成部分,民俗体育运动的发展显得尤为重要.为研究民俗体育项目对健身效果的影响,组织多个对象分别进行一段时间内的角力类、竞足类和技巧类三类民俗体育运动训练,并观察对象训练后在身体形态、身体机能、身体素质三方面共计32个代表性身体指标的变化情况.进一步,以身体指标变化情况作为特征表示观察对象,采用随机森林算法预测不同对象在训练阶段进行民俗体育运动的种类,在过程中基于信息增益进行特征选择,从而度量不同类别民俗体育运动对各项身体指标的影响程度.将获得的不同运动对各项身体指标的影响程度与真实影响情况进行评估分析,揭示民俗体育运动与人身体机能的关联关系.此外,实验结果证明,和基准线算法相比,提出的算法有更高的预测准确性.With the development of sports,more and more attention has been paid to traditional sports.As an important part of Chinese traditional sports,the development of folk sports is particularly important.In order to study the influence of folk sports on the effect of physical fitness,this article organizes a number of subjects to conduct three types of folk sports training including wrestling,foot races and skills sports for a period of time,and observes a total of 32 representative body indicators in three aspects:body shape,physical function and physical fitness after training.As for a further comment,based on the changes of indicators,this article uses changes in physical indicators as features to represent individuals.Random forest algorithm is used to predict what kind of folk sports different objects will perform in the training phase.In the process,feature selection is based on information gain to measure impact.Thus,it measures the influence degree of different types of folk sports on body indicators.In this paper,the influence degree of different folk sports on body indicators and actual impact are evaluated and studied to reveal the correlation between folk sports and human body functions.In addition,the experimental results show that the proposed algorithm has higher prediction accuracy than the baseline algorithm.
