The purpose of this study was to investigate the influence of the task conditions on 20-m side foot-kick accuracy among Swedish first league women's soccer players. Twenty-three players performed three side foot-kick tests under different task conditions: stationary ball using match-relevant ball speed (SBRS) and maximal ball speed (SBMS) and a 5-m run with the ball from different approach angles (0°, 30°, and 60°) to a predetermined position, where passing of the ball on the move was executed using match-relevant ball speed (RBRS). With each test, the players performed 30 side-foot kicks, alternating between kicking legs with the aim of hitting a target stick. The accuracy was determined using video analysis. The side foot-kick accuracy was significantly greater for SBRS, compared to RBRS and SBMS. For all three test variables, the preferred leg displayed greater accuracy. The preferred leg's accuracy was greater for the approach angle of 30° compared to both 0° and 60°. A significant deviation from the target stick was found for the straight-ahead approach, in which the right-foot and left-foot kicks deviated to respectively the left and right of the stick; in contrast, for the approach angle of 60°, the deviation from the target stick was on the opposite side of the approach side for both legs.
本研究的目的是调查任务条件对瑞典甲级女子足球运动员20米侧踢准确性的影响。23名运动员在不同任务条件下进行了三次侧踢测试：使用与比赛相关的球速（SBRS）和最大球速（SBMS）踢固定球，以及从不同接近角度（0°、30°和60°）带球跑5米至预定位置，在移动中传球时使用与比赛相关的球速（RBRS）。每次测试时，运动员进行30次侧踢，两腿交替，目标是击中一根目标杆。使用视频分析确定准确性。与RBRS和SBMS相比，SBRS的侧踢准确性显著更高。对于所有三个测试变量，优势腿表现出更高的准确性。与0°和60°相比，优势腿在30°接近角度时的准确性更高。发现直线接近时与目标杆有显著偏差，其中右脚和左脚踢分别偏向杆的左侧和右侧；相反，对于60°接近角度，两腿与目标杆的偏差都在接近侧的相反一侧。
