This study aimed to determine if ball position influences the risk of lower limb non-contact injury in hockey sweep pass. It also aimed to determine a ball position that minimises excessive strain placed on the lower limb joints of the lead leg during the sweep pass.
A cohort of 18 female hockey-playing volunteers (age: 19.7±1.5 years; height: 165.5±5.4 cm; body mass: 66.4±7.0 kg) were recruited. Participants performed the sweep pass using three different ball positions: in front, in line with, and behind the heel of the lead (left) foot.Motion analysis and force plate data were collected. Moments and angles in all three planes of motion for the three main lower limb joints were then calculated using Vicon software. Results were statistically analysed using SPSS software.
Significant differences (p<0.05) were found between the three tested ball positions for the mean maximum angles and moments, and mean ranges of motion produced at the lead three main lower limb joints. Positioning the ball in line with the heel of the lead foot resulted in the lowest moments and angles when compared with the other two ball positions.
The results indicate that positioning the ball in line with the heel of the lead foot is recommended to minimise the risk of injury to the lower limb joints during the hockey sweep pass. It is hoped that these findings will result in this position being implemented by players new to hockey or those returning to the sport following injury.
本研究旨在确定球的位置是否会影响曲棍球扫传球时下肢非接触性损伤的风险。同时还旨在确定一个球的位置，以使扫传球过程中支撑腿下肢关节所承受的过度压力最小化。
招募了18名女性曲棍球志愿者（年龄：19.7±1.5岁；身高：165.5±5.4厘米；体重：66.4±7.0千克）。参与者使用三种不同的球位置进行扫传球：在支撑（左）脚脚跟前方、与脚跟对齐、在脚跟后方。收集了运动分析和测力板数据。然后使用Vicon软件计算三个主要下肢关节在所有三个运动平面中的力矩和角度。使用SPSS软件对结果进行统计分析。
在三个测试的球位置之间，主要支撑腿三个下肢关节产生的平均最大角度和力矩以及平均运动范围存在显著差异（p<0.05）。与其他两个球位置相比，将球与支撑脚的脚跟对齐时产生的力矩和角度最低。
结果表明，建议将球与支撑脚的脚跟对齐，以尽量减少曲棍球扫传球过程中下肢关节受伤的风险。希望这些发现能使曲棍球新手或受伤后重返这项运动的运动员采用这个位置。
