Speranza, MJA, Gabbett, TJ, Greene, DA, Johnston, RD, and Sheppard, JM. Changes in rugby league tackling ability during a competitive season: the relationship with strength and power qualities. J Strength Cond Res 31(12): 3311-3318, 2017-This study examined the relationship between changes in tackling ability, and muscular strength and power during a semiprofessional rugby league competitive season. Twelve semiprofessional rugby league players (mean ± SD age, 23.3 ± 2.0 years) underwent tests of upper- and lower-body strength and power during the preseason period. Tackling ability was tested using video analysis of a standardized one-on-one tackling drill. Players repeated these tests after round 15 of a 25-match competitive season. Changes in 1 repetition maximum (1RM) squat (rs = 0.70; p < 0.02) and squat relative to body mass (rs = 0.73; p < 0.01) were significantly related to changes in tackling ability. Players with the greatest improvements in tackling ability (i.e., "responders") retained 1RM squat (effect size, ES = 0.85, p = 0.09) and squat relative to body mass (ES = 0.82, p = 0.15) to a greater extent than the "nonresponders." The results of this study suggest that players who retained lower-body strength were able to improve tackling ability during the competitive season, whereas reductions in lower-body strength were associated with decrements in tackling ability. This study highlights the importance of the development and maintenance of lower-body muscular strength for effective tackling performance throughout the rugby league season.
斯佩兰萨、MJA、加贝特、TJ、格林、DA、约翰斯顿、RD 和谢泼德、JM。在一个竞争赛季中橄榄球联赛触地得分能力的变化：与力量和力量素质的关系。J 强能力研究 31（12）：3311-3318，2017 年-本研究考察了在半职业橄榄球联赛竞争赛季中触地得分能力变化与肌肉力量和力量之间的关系。12 名半职业橄榄球联赛运动员（平均 ± SD 年龄，23.3 ± 2.0 岁）在季前赛期间接受了上下体力量和力量测试。使用标准化一对一触地得分练习的视频分析测试触地得分能力。球员们在 25 场比赛的 15 轮比赛后重复这些测试。1 次最大重复（1RM）深蹲（rs = 0.70；p <0.02）和深蹲相对于体重的变化（rs = 0.73；p <0.01）与触地得分能力的变化显著相关。触地得分能力提高最大的球员（即“反应者”）保持了 1RM 深蹲（效应量，ES = 0.85，p = 0.09）和深蹲相对于体重的变化（ES = 0.82，p = 0.15）的程度大于“非反应者”。本研究的结果表明，保持下半身力量的运动员能够在竞争赛季中提高触地得分能力，而下半身力量的下降与触地得分能力的下降有关。本研究强调了发展和维持下肢肌肉力量对于整个橄榄球联赛赛季有效触地得分表现的重要性。
