Homer, KA, Cross, MR, and Helms, ER. A survey of resistance training practices among physique competitors during peak week. J Strength Cond Res 38(10): 1745-1752, 2024-Physique athletes are ranked by their on-stage presentation of muscle size, proportionality, and leanness. To acutely maximize muscle size, competitors manipulate resistance training (RT) variables in the days before the contest, commonly referred to as peak week (PW). Resistance training manipulations during PW may act synergistically with nutrition strategies such as carbohydrate loading. However, because little information exists on changes made to RT during PW, the purpose of this research was to determine the current practices of physique athletes and whether competitor characteristics were predictive of the RT variables manipulated. A total of 104 responses to the RT section of a survey on PW nutrition and training were analyzed through a series of multiple logistic regression models to examine the relationship between RT manipulations and competitor characteristics. Furthermore, to determine the magnitude of differences between PW and the week before PW (WBPW) for these variables, a McNemar-Bowker test, paired t-tests, and Wilcoxon signed-rank tests were conducted for nominal, continuous, and discrete outcomes, respectively. For all statistical analyses, p <0.05 was deemed significant. Competitors generally adjusted RT in a variety of ways, where proximity-to-failure was the most frequently manipulated and training frequency was the least; however, no competitor characteristic predicted any of the RT variables manipulated. Within those who manipulated RT variables during PW, frequency, volume, and intensity decreased while repetition ranges of compound exercises increased, empirically confirming that competitors seek to reduce training stress during PW. Such findings can be incorporated in future experimental designs examining the efficacy of peaking strategies to enhance the generalizability of results.
霍默、KA、克罗斯、MR和赫尔姆斯、ER。巅峰周期间健体运动员抗阻训练实践的调查。《力量与体能研究杂志》38(10): 1745 - 1752，2024年——健体运动员根据其在舞台上展示的肌肉大小、比例和体脂率进行排名。为了在短期内最大化肌肉尺寸，运动员在比赛前几天会调整抗阻训练（RT）变量，这通常被称为巅峰周（PW）。巅峰周期间的抗阻训练调整可能与诸如碳水化合物负荷等营养策略协同作用。然而，由于关于巅峰周期间抗阻训练变化的信息很少，本研究的目的是确定健体运动员目前的训练实践，以及运动员特征是否能预测所调整的抗阻训练变量。通过一系列多元逻辑回归模型，对一项关于巅峰周营养和训练的调查中抗阻训练部分的104份回复进行了分析，以检验抗阻训练调整与运动员特征之间的关系。此外，为了确定这些变量在巅峰周和巅峰周前一周（WBPW）之间的差异程度，分别对名义变量、连续变量和离散变量进行了麦克内马尔 - 鲍克检验、配对t检验和威尔科克森符号秩检验。对于所有统计分析，p <0.05被视为具有统计学意义。运动员通常会以多种方式调整抗阻训练，其中接近极限的训练是最常调整的，而训练频率是调整最少的；然而，没有任何运动员特征能够预测所调整的任何抗阻训练变量。在巅峰周期间调整抗阻训练变量的运动员中，训练频率、训练量和强度下降，而复合动作的重复次数范围增加，从经验上证实了运动员在巅峰周期间试图降低训练压力。这些发现可纳入未来的实验设计中，以检验巅峰策略的有效性，从而提高研究结果的普遍性。
