Wade, JA, Fuller, JT, Devlin, PJ, and Doyle, TLA. Senior and junior rugby league players improve lower-body strength and power differently during a rugby league season. J Strength Cond Res 36(5): 1367-1372, 2022-This investigation evaluated lower-body strength and power changes across a rugby league season in elite junior and senior athletes. Twenty-five senior and 20 junior rugby league players performed an isometric midthigh pull and countermovement jump at 3 time points in a National Rugby League training season (mid-preseason, end-preseason, and in-season). Linear fixed-effects models were used to compare isometric midthigh pull force and countermovement jump power between player experience groups (senior vs. junior) across the season phases (mid-preseason vs. end-preseason vs. and in-season). Cohen's effect sizes (ES) with 95% confidence intervals were calculated for pairwise comparisons. For senior players, absolute and relative strength (ES = 0.38, p < 0.007) and power (ES = 0.64, p < 0.008) increases were observed at end-preseason compared with mid-preseason, but there were no changes in-season (ES = 0.02, p > 0.571). For junior players, strength did not change (ES < 0.01, p > 0.738) and absolute power decreased (ES = 0.29, p < 0.014) at end-preseason compared with mid-preseason; large increases were evident for absolute and relative strength (ES = 1.43, p < 0.001) and power (ES = 0.62, p < 0.001) in-season. This research demonstrates senior and junior rugby league players exhibit unique patterns of improvements in lower-body strength and power across different phases of the season. This highlights the importance for training programs to differ between junior and senior athletes and target different physical qualities for both groups at different times of the season, thus providing guidance for strength and conditioning coaches.
韦德、J.A.、富勒、J.T.、德夫林、P.J.和多伊尔、T.L.A. 高级和初级橄榄球联盟球员在橄榄球联盟赛季中提高下肢力量和功率的方式有所不同。《力量与体能研究杂志》36(5): 1367 - 1372, 2022 - 本调查评估了精英初级和高级运动员在整个橄榄球联盟赛季中下肢力量和功率的变化。25名高级和20名初级橄榄球联盟球员在国家橄榄球联盟训练赛季的3个时间点（季前赛中期、季前赛末期和赛季中）进行了等长大腿中部拉伸和反向移动跳跃测试。使用线性固定效应模型比较赛季各阶段（季前赛中期与季前赛末期与赛季中）球员经验组（高级与初级）之间的等长大腿中部拉力和反向移动跳跃功率。计算了两两比较的科恩效应量（ES）及其95%置信区间。对于高级球员，与季前赛中期相比，季前赛末期观察到绝对力量和相对力量（ES = 0.38，p < 0.007）以及功率（ES = 0.64，p < 0.008）增加，但赛季中没有变化（ES = 0.02，p > 0.571）。对于初级球员，与季前赛中期相比，季前赛末期力量没有变化（ES < 0.01，p > 0.738）且绝对功率下降（ES = 0.29，p < 0.014）；赛季中绝对力量和相对力量（ES = 1.43，p < 0.001）以及功率（ES = 0.62，p < 0.001）有明显大幅增加。本研究表明，高级和初级橄榄球联盟球员在赛季不同阶段下肢力量和功率的提高呈现出独特模式。这凸显了训练计划在初级和高级运动员之间存在差异的重要性，以及在赛季不同时间针对两组运动员的不同身体素质进行训练的重要性，从而为力量与体能教练提供了指导。
