| Abstract: | Using main component and factor analysis method, an analysis was made of the strength quality of 21 outstanding hammer athletes in our country. The results show:1.Different strength indes numbers lead to different sequence of strength factors. To ensure the accuracy of the sequence of strength factors, the numbers of the strength index of all the main factors should be the same.2.of all the main factors of strength quality, special throw strength factor has the greatest, speed strength the second, basic strength the least impact on the effect of hammer throw. |
