影响铅球运动员专项成绩的素质评价模型

Quality evaluation model of factors influencing shot athletes' event-related performances

将数理统计的因子分析模型、回归分析模型应用于运动员素质的评价。将直接影响运动员专项成绩的身体素质指标建立了相关的数学模型,研究了各身体素质指标与专项成绩之间的相关关系,提出对青少年运动员应优先发展其速度素质、爆发力素质和灵活性素质,并给出了身体素质指标与铅球成绩的预测与控制方案。

The mathematical factor analysis model and retrogression analysis model were applied in evaluat- ing the athletes＇ qualities. Relative mathematical model was set up concerning the athletes＇ physical fitness influencing their event-related performances. Relationships between physical fitness indexes and the performances were studied. It was proposed that speed quality, explosive quality and pliability should be given priority in training the juvenile athletes. Moreover, predication and controlling schemes for physical fitness indexes and shot performances were given.
