本研究的目的是 (i) 描述和分析国际曲棍球队在竞技比赛中的替补战术，以及 (ii) 确定替补时间对重新进入活跃比赛时球员体力输出的影响。数据收集自 13 名职业男子曲棍球运动员在三场国际锦标赛中的数据。运动员的体能表现由高频局部位置测量系统记录。换人次数和时长通过观察获得。一场锦标赛比赛期间，平均换人次数为 58.0 ± 4.6 次，其中球员平均进行 4.7 ± 0.8 次个人换人，平均停顿时间为 5.4 ± 1.2 分钟，平均上场时间为 7.18 ± 2.14 分钟。在换人的第一分钟内，重新上场的球员的总距离（159.7 +/- 33.0 m.min(-1)）明显高于球队平均距离（139.4 +/- 33.3 m.min(-1)）。在换人后的第五分钟内，我们观察到身体表现显着下降。我们的研究结果表明存在“第一分钟冲刺效应”，即替补队员的总距离明显大于球队平均水平。此外，重新上场的曲棍球运动员在换人后大约四分钟就会出现明显的疲劳迹象。
The purpose of this study was to (i) describe and analyse the substitution tactics of an international field hockey team during competitive match play and (ii) to identify the impact of bench periods on the physical output of players when re-entering active game play.Data were collected from thirteen professional male field hockey players during three international tournament matches. The physical performance of the players was recorded by a high-frequency local position measurement system. The number and length of substitutions were obtained by observation.An average of 58.0 +/- 4.6 substitutions were registered during the course of a tournament match, where the average player performed 4.7 +/- 0.8 individual substitutions with an average pause duration of 5.4 +/- 1.2 min and an average on-field playing duration of 7.18 +/- 2.14 min. Within the first minute of substitution, re-entering players covered a significantly larger total distance (159.7 +/- 33.0 m.min(-1)) compared with the team average (139.4 +/- 33.3 m.min(-1)). A significant decrease in physical performance was observed within the fifth minute after substitution.Our findings suggest a ` first-minute-rush-effect', wherein substitutes covered a significantly larger total distance compared with the team average. Further, re-entering field hockey players experienced distinguishable signs of fatigue approximately four minutes after substitution.
