【摘要】 利用奥地利WEBA Sport公司的Rower Expert Light赛艇实船测试系统对4名女子公开级赛艇运动员进行单人双桨实船划桨测试。分析发现:随着桨频的增加,拉桨与推桨更加迅速,但推桨速度增加得更快。桨频的增加会使得拉桨速度加快但并没有伴随着拉力的显著增加,而拉力的大小对于艇速并不起决定性作用。在相同桨频下,较小的单次划桨时间,较小的推拉比有助于获得较快的艇速。运动员左右手拉力的不平衡以及最大力产生的位置不一致都会影响到赛艇的航向与航速。在三种测试桨频下4名运动员的入水角都大于出水角。随着桨频的增加,转桨角的变化幅度不大,但较大的转桨角有助于提高艇速。随着桨频的提高,正加速度和负加速度变得越来越大,但负加速度持续的时间以及在划桨周期中所占的比例在减小,这对于提高艇速显然是有利的。更多还原

【Abstract】 4 Chinese elite open-women rowers are chosen by making use of the "Rower Expert Light"(WEBA Sport) to collect the data of single scull rowing technique and analysis.It shows: with the increase of tempo,drive and recovery become more rapid,but push propeller speed increases even faster.There is no significant increase in the strength of drive,and the strength of drive for boat speed does not play a decisive role.Under the same tempo,and less single paddle time,the less ratio of push and pull will help get faster boat speed.The imbalance of right-left pulling force and the different position of the most strength of drive will affect the course and speed.In 3 tempos,4 athletes’ angle of entry always is greater than their angle of release.With the increase of tempo,the angle of hands away is of no significant change,but the bigger angle of hands away will help increase boat speed.With the increase of tempo,positive acceleration and negative acceleration are increasing too,but range of negative acceleration and the proportion of range of negative acceleration among stroke cycle time decrease,which obviously is in favour of increase boat speed.更多还原
