Abstract

Research for index weight of aerobics performance evaluation based on multiple regression

Author(s): Yuanqing Xia

In the paper, the many indexes related aerobics sports performance are obtained bymaking a survey to aerobics specialist, eventually, fromwhich nine indexes are selected. Experts score 9 indicators and give the total score. Scoring index results is just taken into account without considering the factors of special grade. On the basis of the 9 indexes data, multiple regressions is used to make fitting analysis to data using SPSS, and then forecasting model ofAerobics result is finally obtained. Results show that the model can better predict the total scores of aerobics performance, meanwhile, coefficient of index determine the weight of theAerobics index in the total results.Multiple regression models can predict performance of Aerobics athletes reasonable and scientifically, and provide an important basis for Aerobics training
