摘要: 为了解我国优秀女子7人制橄榄球运动员在比赛中的跑动能力, 使用全球定位技术系统对国家女子橄榄球队12名主力运动员参加2015年IRB世界橄榄球巡回赛美国站5场比赛的数据进行时间-运动分析, 研究结果显示, 我国优秀女子橄榄球运动员在14 min的比赛中跑动距离为1 191.67±162.46 m, 其中, 休息与走占34% (405.33±64.53 m) 、慢跑占28% (334.33±47.82 m) 、中低速跑占9% (109.3±14.57 m) 、中高速跑占15% (176.33±23.12 m) 、高强度快速跑占6% (74.91±33.65 m) 、冲刺跑占8% (91.67±14.64 m) , 运动员的工作休息比约为1:0.5, 最大速度为6.97±0.38m/s, 平均速度为66±4.36 m/min, 冲刺跑5.62±0.58次;不同位置的我国优秀女子橄榄球运动员的整体跑动能力没有明显差别;与国外优秀女子橄榄球运动员相比, 我国优秀女子橄榄球运动员在跑动能力方面可能存在一定差距。Abstract: The purpose of this study was to understand running ability of Chinese elite female rugby players competing in rugby sevens matches. Time-motion analyses (global position system) were performed on data of 12 elite female rugby players during 5 competitive matches in series of IRB international tournament in USA. Data revealed that players covered an distance of 1 191.67±162.46 m per game (14 min) . Over this distance, 34% (405.33±64.53 m) was spent standing and walking, 28% (334.33±47.82 m) jogging, 9% (109.3±14.57 m) cruising, 15% (1 76.33±23.12 m) striding, 6% (74.91±33.65 m) high-intensity running, and 6% (91.67±14.64 m) sprinting. The players' work-to-rest ratio was about 1:0.5. The maximal speed, average speed and number of sprints over the game were as follows:6.97±0.38 m/s, 66±4.36 m/min and 5.62±0.58 sprints respectively. There were no differences between demands of running ability on our elite female rugby players at different position. Comparing with foreign elite female rugby sevens players, there were likely disadvantages in running ability of our players.
