Abstract

ABSTRACT Instruction: Effective playing time in soccer is typically < 60 min per game and while players may reposition themselves when the ball is out of play, it is likely the physical demand decreases during this period. Therefore, if this period is included in data when quantifying match demands, it may under-report the physical requirements of soccer players. This study investigated an alternative method for quantifying external workload called ball in play (BiP), which analyses the data excluding stoppages, and thus potentially offers a more insightful analysis of match demands.Methods: Whole match demands as typically recorded via GPS, were compared to those based on BiP, and maximum BiP, with the latter representing worst case scenario phases of play. The 25-elite male youth soccer players (age: 17.9 ± 0.6 years; height: 174.8 ± 6.2 cm; body mass: 66.3 ± 8.1 kg) who participated in this study were also categorised in to positional groups (defender, midfielder, and forward) to assess differences in positional demands.Results: While no differences were noted based on position, whole match metrics were significantly lower than mean and maximum BiP metrics (p < 0.05). There was also a significant difference for maximum BiP outputs across different in-play durations, when comparing 30-60 seconds, 60–90 seconds, and > 90 seconds.Conclusion: This data allows practitioners to gain a deeper understanding of the physical demands imposed on players and plan sessions using targets that better represent match demands.

优秀青年男子足球运动员在比赛中使用球与整场比赛数据的比赛需求比较
摘要:足球比赛的有效比赛时间通常小于60分钟,当球出球时,球员可能会重新定位,在此期间,身体需求可能会减少。因此,如果在量化比赛需求时将这段时间纳入数据,可能会低估足球运动员的身体需求。本研究研究了一种量化外部工作量的替代方法,称为比赛中球(BiP),该方法分析了不包括暂停的数据,从而可能提供更有洞察力的比赛需求分析。方法:通常通过GPS记录的整个比赛需求,与基于BiP和最大BiP的需求进行比较,后者代表游戏的最坏情况阶段。25名优秀青年男子足球运动员(年龄:17.9±0.6岁;高度:174.8±6.2 cm;体重:66.3±8.1 kg)的参与者也被分为位置组(后卫、中场和前锋),以评估位置需求的差异。结果:虽然体位差异无统计学意义,但整体匹配指标显著低于平均和最大BiP指标(p < 0.05)。在30-60秒、60-90秒和> - 90秒之间,在不同的游戏持续时间内,最大BiP输出也存在显著差异。结论:这些数据使从业者能够更深入地了解球员的身体需求,并使用更好地代表比赛需求的目标来计划训练。
