This study investigated the physical qualities that discriminated state-based rugby league players competing for selection in a semiprofessional rugby league team, and determined the relationship between tests of physical qualities and physical match performance in these players. Thirty-two rugby league players (mean ± SD age, 24 ± 3 years) from a Queensland Cup rugby league squad participated in this study. The players performed tests of upper-body strength (3 repetition maximum [RM] bench press; 3RM weighted chin-up), upper-body strength endurance (body-mass maximum repetition bench press), lower-body strength (3RM squat), lower-body power (vertical jump), and prolonged high-intensity intermittent running ability (Yo-Yo intermittent recovery test, level 1). Global positioning system data, sampling at 10 Hz, were collected during 5 Queensland Cup rugby league matches. Selected players had greater (p < 0.05) 3RM squat, 3RM chin-up, body-mass bench press, vertical jump, and Yo-Yo intermittent recovery test performances than nonselected players. After controlling for playing position, players with better 3RM squat performances covered greater total distances (r = 0.98, p < 0.05) including greater distances at low (r = 0.98, p < 0.05) and high (r = 0.97, p < 0.05) speeds. Significant associations (r = 0.96, p < 0.05) were also found between 3RM squat performances and the number of repeated high-intensity effort bouts performed in competition. These findings highlight the importance of lower-body strength, upper-body strength and endurance, and prolonged high-intensity intermittent running ability to team selection in semiprofessional rugby league. Furthermore, our findings suggest that well-developed lower-body strength contributes to effective physical match performance in semiprofessional rugby league players.
本研究调查了区分参加半职业联盟球队选拔赛的基于州的橄榄球联盟球员的身体素质，并确定了这些球员身体素质测试与身体比赛表现之间的关系。来自昆士兰州杯橄榄球队的 32 名橄榄球运动员（平均±SD 年龄，24±3 岁）参加了这项研究。球员们进行了上身力量测试（3 次最大重复[RM]卧推；3RM 负重引体向上）、上身力量耐力测试（体重最大重复卧推）、下身力量测试（3RM 深蹲）、下身力量测试（3RM 深蹲）、下身力量测试（3RM 深蹲）、下身力量测试（3RM 深蹲）、下身力量测试（3RM 深蹲）和长时间高强度间歇跑能力测试（Yo-Yo 间歇恢复测试，水平 1）。在 5 场昆士兰州杯橄榄球比赛中，以 10 Hz 的频率收集全球定位系统数据。选定的球员比非选定的球员具有更高的（p<0.05）3RM 深蹲、3RM 引体向上、体重卧推、垂直跳跃和 Yo-Yo 间歇恢复测试表现。在控制比赛位置后，3RM 深蹲表现较好的球员覆盖的总距离更大（r=0.98，p<0.05），包括低速（r=0.98，p<0.05）和高速（r=0.97，p<0.05）的距离更大。还发现 3RM 深蹲表现与比赛中重复高强度努力回合的次数之间存在显著关联（r=0.96，p<0.05）。这些发现强调了下肢力量、上肢力量和耐力以及长时间高强度间歇跑能力对半职业橄榄球联盟球队选拔的重要性。此外，我们的研究结果表明，发达的下肢力量有助于半职业橄榄球联盟球员在身体比赛中表现出色。
