Otaegi, A and Los Arcos, A. Quantification of the perceived training load in young female basketball players. J Strength Cond Res 34(2): 559-565, 2020-The purposes of this study were (a) to compare training session, match, and weekly perceived training load (TL) between U15 and U16 female basketball players and (b) within the teams, to assess the relationship between perceived TL and the changes in physical fitness performance during an in-season 9-week period. Twenty-one female players from U15 and U16 female teams from the same Spanish club participated in the study. Before and after the study, players were tested to determine physical fitness performance (using Yo-Yo IR1, countermovement jump, T-Test, and 15 m sprint). Each player declared her perceived exertion (PE) for the whole training session and match using Foster's 0-10 scale. Training week perceived TL was higher for the U16 players than the U15 players; U16 players considered the training and matches to be more difficult. In both teams, the perceived TL of the last training session of the week was significantly lower (Effect sizes = large-very large) than the other sessions. Although substantial negative associations (r = 0.52-0.78) were detected between the changes in physical fitness performance and the accumulated volume, sum of PEs and perceived TL in the U15 players, these associations were unclear in the U16 players. The basketball coaches-periodized training goals are to attain the highest session perceived TLs in the middle of the week and to reduce it considerably in the last training session. The U16 and U15 players accumulated perceived TL in different ways. Although the practice volume was similar in both teams, the older players consider the sessions more difficult. The relationship between the perceived TL and the changes in physical fitness performance varied between teams. Based on our findings, we propose that the PE-based dose-response model should be applied with caution in young female basketball players.
大埃吉和洛斯阿科斯，年轻女篮球运动员感知训练负荷的量化。J 力量与调节研究 34(2)：559-565，2020-本研究的目的是：(a) 比较 U15 和 U16 女篮球运动员的训练课、比赛和每周感知训练负荷 (TL)；(b) 在各队中，评估感知 TL 与赛季中 9 周期间体能表现变化之间的关系。来自同一西班牙俱乐部的 U15 和 U16 女子篮球队的 21 名女运动员参加了这项研究。在研究前后，运动员的体能表现(使用 Yo-Yo IR1、反跳、T 测试和 15 m 冲刺)都要进行测试。每位运动员都用福斯特的 0-10 量表来表示她对整个训练课和比赛的感知用力。U16 球员的训练周感知 TL 高于 U15 球员；U16 球员认为训练和比赛更难。在两个队中，周中最后一次训练课的感知 TL 明显低于其他训练课(效应大小=大-非常大)。尽管在 U15 运动员中，体能表现的变化与累积量、PE 总和和感知 TL 之间存在显著的负相关关系(r = 0.52-0.78)，但在 U16 运动员中，这些关系并不明确。篮球教练们的训练目标是在周中达到最高的感知 TL，并在最后一次训练课中大大降低它。U16 和 U15 球员以不同的方式积累感知 TL。尽管两个队的练习量相似，但年龄较大的运动员认为训练课更难。感知 TL 与体能表现变化之间的关系在两个队之间有所不同。根据我们的发现，我们建议在年轻女篮球运动员中谨慎应用基于感知用力的剂量反应模型。
