摘要

The purpose of the study is to analyze the discus throwing hand raising height, throwing angle, primary throwing speed, time of reaching the highest point, height of the highest point, full-range time, and throwing distance, and analyze the candidate height, weight, and the best throwing distance, etc., with total 16 candidates of college male/female discus as study target, by applying 16mm camera to shoot the whole motion process of a candidate in throwing a discus. A film, after production, is laid into a film analyzer, to calculate each related dynamic element to discus sports, through quantity statistics and discussion analysis, the conclusions can be obtained as follows:I. Talking about physical shape, in the aspect of male candidate, the average height value of candidates is 181.25cm. In the aspect of female candidate, the average height value of candidates is 165.25cm. besides, talking about weight, in the aspect of male candidate, the average weight value of candidates is 105.625kg. In the aspect of female candidate, the average weight value of college candidates is 72.875kg.II. It is known from various dynamic data of male group discus that, the average value of hand raising height while throwing is 1.6075m, the average value of throwing angle is 33.875°, and the average value of primary throwing speed is 21.3125m/second. III. It is known from various dynamic data of female group discus that, the average value of hand raising height while throwing is 1.44m, the average value of throwing angle is 31.5°, and the average value of primary throwing speed is 20.2375m/second.IV. It is known from various dynamic data of male group discus that, the relativity of primary throwing speed and throwing angle r=0.94086, reaching extremely obvious relativity (P＜.01), the relativity of throwing angle and throwing speed r=0.97553, reaching extremely obvious relativity (P＜.01), the relativity of primary, throwing speed and throwing speed r=0.99185, reaching extremely obvious relativity (P＜.01).V.
