Abstract

The purpose of this study was to compare the most demanding scenarios (MDS) encountered by professional basketball players across game quarters and playing positions during official match-play. Ten professional bas- ketball players were monitored during 11 matches using a local positioning system. Peak physical demands were measured via total distance, distance >18 and >21 km·h -1 , number of sprints >18 and >21 km·h -1 , and number of accelerations and decelerations >2 and >3 m∙s -2 captured over 30, 60, 120, 180, and 300-s rolling averages. Linear mixed models and effect sizes (ES) were used to compare MDS encountered between game quarters and playing positions. Between Quarters 1 and 2, there was a reduction in the total distance (ES = 0.64-1.39) for all playing groups along with a reduction in distance >21 km·h -1 in centres (ES = 0.77-0.81) and a reduction in accelerations and decelerations >2 m∙s -2 in guards (ES = 0.66-0.78) across longer sample periods (180-300-s). Between Quarters 1 and 4, reductions in the total distance were evident for forwards and centres (ES = 0.64-0.91) as well as distance and sprints >21 km·h -1 in centres (ES = 0.64-0.97). Regarding positional differences, guards and forwards covered a higher total distance than centres across most quarters and sample periods (ES = 0.22-1.44). Our data suggest a decrease in MDS with game progression in basketball. In addition, MDS appear to be duration-specific and posi- tion-dependent in basketball. Therefore, practitioners should consider these differences in MDS based on game quarters and positional demands to optimise individual and team performance.
职业球员在最苛刻的篮球对抗赛场景下的比赛区域和位置差异
本研究的目的是比较职业篮球运动员在正式比赛中所遇到的最苛刻的场景(MDS)。10名职业篮球运动员在11场比赛中使用本地定位系统进行了监测。通过在30、60、120、180和300秒滚动平均时间内捕获的总距离、距离>18和>21 km·h -1、冲刺次数>18和>21 km·h -1以及加速和减速次数>2和>3 m∙s -2来测量峰值物理需求。使用线性混合模型和效应大小(ES)来比较游戏区域和游戏位置之间遇到的MDS。在第1季度和第2季度之间,所有比赛组的总距离都减少了(ES = 0.64-1.39),中心的距离减少了>21 km·h -1 (ES = 0.77-0.81),后卫的加速和减速减少了>2 m∙s -2 (ES = 0.66-0.78),时间更长(180-300-s)。在第1和第4季度之间,前锋和中锋的总距离明显减少(ES = 0.64-0.91),中锋的距离和冲刺>21 km·h -1 (ES = 0.64-0.97)。就位置差异而言,后卫和前锋在大多数季度和样本期间的总距离高于中锋(ES = 0.22-1.44)。我们的数据表明,随着篮球比赛的进展,MDS会减少。此外,在篮球运动中,MDS似乎是持续时间特异性和位置依赖性的。因此,从业者应该根据比赛场地和位置需求来考虑MDS的这些差异,以优化个人和团队的表现。
