To ascertain the typical metabolic power characteristics of elite handball players of different positions, and whether changes occur within matches.
414 elite male handball players were included. During all 65 matches of the EURO 2020, local positioning system data were collected, yielding 1853 datasets. Field players were categorised into six positional groups: centre backs (CB), left/right wings (LW/RW), left/right backs (LB/RB) and pivots (P). Metabolic power, total energy expenditure, high-power energy, and the equivalent distance index were calculated. We used linear mixed models with players as random and positions as fixed effects models. Intensity models adjusted for time-dependency by incorporating the duration of play.
LW/RW spent most time on the court, expanded most total energy, and most relative energy per kg body weight in the high-intensity categories. CB played at the highest mean metabolic power (7.85 W/kg; CI [7.67, 8.03]). Playing intensity decreased by 2.5% (0.2 kJ/kg/s; CI [0.17, 0.23]) per 10 min played.
Positional differences in metabolic power parameters exist. In general, wing players had the highest volume and CB the highest intensity of match-play. Analysis of metabolic intensity in handball should take position and players' time on the court into account.
确定不同位置的精英手球运动员的典型代谢功率特征，以及比赛中是否会发生变化。
纳入414名精英男性手球运动员。在2020年欧洲杯的所有65场比赛中，收集了局部定位系统数据，得到1853个数据集。场上球员被分为六个位置组：中后卫（CB）、左/右翼（LW/RW）、左/右后卫（LB/RB）和中锋（P）。计算代谢功率、总能量消耗、高功率能量和等效距离指数。我们使用以球员为随机效应、位置为固定效应的线性混合模型。强度模型通过纳入比赛时长来调整时间依赖性。
LW/RW在场上花费的时间最多，在高强度类别中消耗的总能量和每千克体重的相对能量最多。CB的平均代谢功率最高（7.85 W/kg；置信区间[7.67, 8.03]）。每比赛10分钟，比赛强度下降2.5%（0.2 kJ/kg/s；置信区间[0.17, 0.23]）。
代谢功率参数存在位置差异。一般来说，边锋球员的比赛量最大，中后卫的比赛强度最高。手球代谢强度分析应考虑位置和球员在场上的时间。
