【摘要】 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。更多还原

【Abstract】 the video tracking records were completed during 100m tests for wheel-chair racing athletes.And the video analyzing methods were used to analyze the average velocity(AV)、stroke frequencies(SF)、stroke length(SL)、stroke rhythm(SR) in three phases.And the multivariate ANOVA、independent samples T test and person correlation methods were used to do the statistic process for data.The results show that: there are different technique features during different phases in 100m for elite wheelchair race athletes;AV and SL are gradually increasing during IAP、MP、FP phases whereas SF and SR are gradually diminishing;The differences in AV between men and women athletes during MP and FP phases are mainly due to the differences in SL during these two phases.The AV during IAP、MP and FP phases is significant or highly significant negatively correlated with the performances in 100m either for men or for women.更多还原
