Beach handball is a young discipline that is characterized by numerous high-intensity actions. By following up on previous work, the objective was to perform in-depth analyses evaluating external load (e.g., distance traveled, velocity, changes in direction, etc.) in beach handball players. In cross-sectional analyses, data of 69 players belonging to the German national or prospective team were analyzed during official tournaments using a local positioning system (10 Hz) and inertial measurement units (100 Hz). Statistical analyses comprised the comparison of the first and second set and the effects of age and sex (female adolescents vs. male adolescents vs. male adults) and playing position (goalkeepers, defenders, wings, specialists, and pivots) on external load measures. We found evidence for reduced external workload during the second set of the matches (p = 0.005, ηp2 = 0.09), as indicated by a significantly lower player load per minute and number of changes in direction. Age/sex (p < 0.001, ηp2 = 0.22) and playing position (p < 0.001, ηp2 = 0.29) also had significant effects on external load. The present data comprehensively describe and analyze important external load measures in a sample of high-performing beach handball players, providing valuable information to practitioners and coaches aiming at improving athletic performance in this new sport.
沙滩手球是一项年轻的运动，其特点是有许多高强度的动作。通过对先前工作的跟进，本研究的目的是对沙滩手球运动员的外部负荷（例如，跑动距离、速度、变向次数等）进行深入分析。在横断面分析中，使用局部定位系统（10 Hz）和惯性测量单元（100 Hz）对 69 名隶属于德国国家队或有潜力入选的球员在正式比赛中的数据进行了分析。统计分析包括对第一组和第二组数据的比较，以及年龄和性别（女青少年组、男青少年组和男成年组）和场上位置（守门员、后卫、边锋、专家和中锋）对外部负荷指标的影响。我们发现，比赛的第二组的外部工作量减少（p = 0.005，ηp2 = 0.09），这表明球员每分钟的负荷和变向次数明显减少。年龄/性别（p < 0.001，ηp2 = 0.22）和场上位置（p < 0.001，ηp2 = 0.29）也对外负荷有显著影响。本研究数据全面描述和分析了高性能沙滩手球运动员样本中的重要外部负荷指标，为实践者和教练提供了有价值的信息，旨在提高这项新运动的运动员表现。
