The present study aimed to analyse the influence of speed and power abilities in goal situations in professional football. During the second half of the season 2007/08, videos of 360 goals in the first German national league were analysed by visual inspection. For the assisting and the scoring player the situations immediately preceding the goal were evaluated. The observed actions were categorised as: no powerful action, rotation (around the body's centre-line), straight sprint, change-in-direction sprint, jump, or a combination of those categories. Two hundred and ninety-eight (83%) goals were preceded by at least one powerful action of the scoring or the assisting player. Most actions for the scoring player were straight sprints (n = 161, 45% of all analysed goals, P < 0.001) followed by jumps (n = 57, 16%), rotations and change-in-direction sprints (n = 22, 6% each). Most sprints were conducted without an opponent (n = 109, P < 0.001) and without the ball (n = 121, P < 0.001). Similarly, for the assisting player the most frequent action was a straight sprint (n = 137, P < 0.001) followed by rotations (n = 28), jumps (n = 22) and change-in-direction sprints (n = 18). The straight sprints were mostly conducted with the ball (n = 93, P = 0.003). In conclusion, straight sprinting is the most frequent action in goal situations. Power and speed abilities are important within decisive situations in professional football and, thus, should be included in fitness testing and training.
本研究旨在分析速度和力量能力对职业足球进球情况的影响。在 2007/08 赛季的下半赛季,通过视觉观察分析了德国甲级联赛的 360 个进球视频。对助攻球员和进球球员在进球前的情况进行了评估。观察到的动作被分为:无强力动作、旋转(绕身体中线)、直线冲刺、变向冲刺、跳跃或这些类别的组合。298 个(83%)进球前,至少有一名得分或助攻球员有强力动作。得分球员的大多数动作是直线冲刺(n = 161,占所有分析进球的 45%,P < 0.001),其次是跳跃(n = 57,16%)、旋转和变向冲刺(n = 22,各占 6%)。大多数冲刺都是在没有对手(n = 109,P < 0.001)和没有球(n = 121,P < 0.001)的情况下进行的。同样,对于助攻球员,最常见的动作是直线冲刺(n = 137,P < 0.001),其次是旋转(n = 28)、跳跃(n = 22)和变向冲刺(n = 18)。直线冲刺大多是带球进行的(n = 93,P = 0.003)。总之,直线冲刺是进球情况中最常见的动作。力量和速度能力是职业足球决胜时刻的重要因素,因此应包括在体能测试和训练中。
