Abstract

Understanding the influence of contextual factors on physical demands is essential to maximize performance in handball. The purpose of this study was to explore and compare the influence of contextual factors (halves of the match, level of the opponent, match outcome and player role) on external load during official matches in women's handball. Twenty-two semi-professional female players from the Spanish 2nd Division were monitored across 13 official home matches. Total distance covered (TDC), high-speed running distance (HSR), high-intensity breaking distance (HIBD), accelerations (ACC), decelerations (DEC) and PlayerLoad (PL) were collected in absolute and relative values (normalized by playing time) using a local positioning system (WIMU PRO, Realtrack Systems S.L., Almería, Spain). HSR, HSR/min and HIBD/min decreased during the second half (p < 0.05; small effects). Regarding the level of the opponent, high-level and middle-level teams elicited higher TDC/min, HIBD/min and PL/min than low-level teams (p < 0.05; small-moderate effects). Additionally, starter players exhibited higher absolute values of external load (TDC, HSR, HIBD, ACC, DEC and PL) compared to non-starters (p < 0.05; moderate-large effects). Match outcome did not affect the physical demands (p > 0.05). The study indicated that halves of the match, level of the opponent, and player role influenced external load experienced by players during official matches; specifically, starter players showed higher absolute values of external load compared to non-starters. This information should be considered in managing load and developing strategies to minimize fatigue and enhance performance during matches.

所有比赛都需要同样的努力吗?正式女子手球比赛中环境因素对体力需求的影响。
了解环境因素对体力需求的影响对于最大限度地提高手球运动成绩至关重要。本研究的目的是探索和比较女子手球正式比赛期间的环境因素(半场比赛、对手水平、比赛结果和球员角色)对外部负荷的影响。在 13 场正式主场比赛中,对 22 名来自西班牙乙级联赛的半职业女子手球运动员进行了监测。使用本地定位系统(WIMU PRO,Realtrack Systems S.L.,西班牙阿尔梅里亚)收集了总距离(TDC)、高速奔跑距离(HSR)、高强度断裂距离(HIBD)、加速度(ACC)、减速度(DEC)和球员负荷(PL)的绝对值和相对值(按比赛时间归一化)。下半场的 HSR、HSR/min 和 HIBD/min 均有所下降(P < 0.05;影响较小)。在对手水平方面,高水平和中等水平球队的 TDC/min、HIBD/min 和 PL/min 均高于低水平球队(p < 0.05;小-中等影响)。此外,与非首发球员相比,首发球员表现出更高的外部负荷绝对值(TDC、HSR、HIBD、ACC、DEC 和 PL)(p < 0.05;中-大影响)。比赛结果对体能要求没有影响(p > 0.05)。研究表明,半场比赛、对手水平和球员角色会影响球员在正式比赛中承受的外部负荷;具体而言,首发球员的外部负荷绝对值高于非首发球员。在管理负荷和制定策略时应考虑这些信息,以尽量减少疲劳并提高比赛表现。
