This study was designed to provide an overview of weightlifting performance as a function of age group and sex and evaluate the potential of countermovement jump height (CMJH) as a tool to gauge performance potential. Data from 130 youth athletes (female, = 65 & male, = 65) were used to examine progression of performance (Total and Sinclair total) and the relationship between CMJH and Sinclair total while considering interactions between CMJH and age and/or sex. ANOVAs with post hoc analyses revealed that both totals had a statistical first-order polynomial interaction effect between age group and sex and the difference between age groups of 12-13 and 14-15 years old was statistically greater for male than female. A linear model, developed to examine the relationship, revealed that CMJH and CMJH x sex x age rejected the null hypothesis. Our primary findings are that male youth weightlifters have a higher rate of performance progression, possibly owing to puberty, and CMJH may be a better gauging tool for older male youth weightlifters.
本研究旨在概述举重成绩与年龄组和性别的关系，并评估反向纵跳高度（CMJH）作为衡量成绩潜力工具的可能性。来自130名青少年运动员（女性，n = 65；男性，n = 65）的数据用于研究成绩（总成绩和辛克莱总成绩）的进展情况，以及CMJH与辛克莱总成绩之间的关系，同时考虑CMJH与年龄和/或性别的相互作用。方差分析及事后分析显示，两个总成绩在年龄组和性别之间均存在统计学上的一阶多项式交互作用效应，且12 - 13岁和14 - 15岁年龄组之间的差异在男性中比女性在统计学上更大。为研究这种关系而建立的线性模型显示，CMJH以及CMJH×性别×年龄拒绝了原假设。我们的主要发现是，男性青少年举重运动员的成绩进步速度更高，这可能归因于青春期，并且CMJH可能是老年男性青少年举重运动员更好的衡量工具。
