对轮椅竞速运动员的100m测试进行录像跟踪拍摄,用录像分析法计算运动员不同阶段的平均速度(AV)、打轮频率(SF)、打轮距离(SL)、打轮节奏(SR);采用多元方差分析、独立样本T检验和Pearson相关分析等方法对数据进行统计处理。进行结果:轮椅竞速100m中优秀运动员不同运动阶段具有不同的技术特征;AV和SL在IAP、MP、FP阶段是逐步增加的,而SF和SR在这三个阶段是逐步减小的;MP和FP阶段男女运动员AV的差异主要由男女运动员不同的SL造成的;男女运动员在IAP、MP和FP阶段的AV都和总成绩有显著或极显著负相关。
The 100m test of wheelchair racing athletes was recorded by video tracking. The average speed (AV), the playing frequency (SF), the driving speed (SL) and the rhythm of riding (SR) at different stages of the athletes were calculated by video analysis. Multivariate analysis of variance, independent sample T test and Pearson correlation analysis were used to analyze the data. The results showed that the elite athletes in wheelchair race 100m had different technical characteristics in different stages of exercise. AV and SL increased gradually in IAP, MP and FP stages, while SF and SR decreased gradually in these three stages. MP The differences of AV between male and female athletes in FP stage were mainly caused by different SL of male and female athletes. The AV of male and female athletes at stage IAP, MP and FP had a significant or extremely significant negative correlation with the total score.
