Abstract

This investigation determined differences in lower body strength and power between elite junior (17-20 years) and elite senior (open-aged) rugby league athletes. Twenty junior and 25 senior athletes performed an isometric mid-thigh pull, countermovement jump, repeated jump, and broad jump tests during a National Rugby League pre-season. The effects of age (junior vs. senior) and position (adjustables vs. hit-up forwards vs. outside backs) on test results were investigated using a two-way analysis of variance. Cohen’s d effect sizes (ES) and 95% confidence intervals were calculated for pairwise comparisons. Isometric mid-thigh pull absolute peak force was greater for senior players compared to junior players (ES=0.88, p<.05). Countermovement jump absolute peak power was greater for outside backs (ES=1.12) and hit-up forwards (ES=1.23) compared to adjustables (p<.05), greater for senior outside backs compared to junior outside backs (ES=1.53, p<.05), and greater for junior hit-up forwards compared to senior hit-up forwards (ES=1.00, p<.05). This research demonstrated the differences in strength and power of rugby league athletes between playing age and position. Improving lower body strength should be prioritised for athletic development of junior rugby league athletes, with consideration given to requirements across different playing positions.

下半身峰值力量而非力量是精英高级橄榄球联盟球员的重要判别因素

这项调查确定了精英青少年（17-20岁）和精英（开放年龄）橄榄球联盟运动员在下半身力量和力量方面的差异。在国家橄榄球联盟季前赛中，20名初级和25名高级运动员进行了等长大腿中部提拉、反动作跳跃、重复跳跃和跳远测试。使用双向方差分析研究了年龄（初级与高级）和位置（可调整性与命中前锋与外线）对测试结果的影响。计算Cohen的d效应大小（ES）和95%置信区间用于成对比较。与初级球员相比，资深球员的等长大腿中拉绝对峰值力更大（ES=0.88，p<.05）。与可调整球员相比，外后卫（ES=1.12）和上前锋（ES=1.23）的反跳绝对峰值力更强（p<.05，与高级前锋相比，初级前锋的力量更大（ES=1.00，p<.05）。这项研究表明，橄榄球联盟运动员在比赛年龄和位置之间的力量和力量存在差异。青少年联盟运动员的运动发展应优先考虑提高下半身力量，并考虑不同比赛位置的要求。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
