Rugby League is a game of physical contact that involves low-intensity, aerobic exercise, combined with periods of intermittent, intensive anaerobic exercise. Matches consist of two halves, each of 40 minutes, separated by a 10-minute recovery period, and are contested by 2 teams of 13 players (6 forwards and 7 backs). Whilst the amount of time spent by individual players on low-intensity exercise exceeds the duration of high-intensity exercise, the nature of the high-intensity efforts (involving sprinting, lower- and upper-body impacts and high force generation) is such that the overall intensity of the game is greatly increased. Individual players have been shown to cover distances of approximately 5000 to 8000m a game, and be involved in 20 to 40 tackles. Maximum oxygen uptake (VO2max) values of around 56 ml/kg/min have been reported for rugby league players, with no differences between the values of forwards and backs. Forwards have, however, been shown to generally have higher body mass, subcutaneous fat and fat-free mass levels than backs. Backs have been found to be quicker than forwards and produce greater leg power output when related to fat-free mass. The amount of physiological data on rugby league players and the sport of rugby league is very limited, and there is considerable scope for future research in this area.
英式橄榄球联盟是一项身体接触性运动，包含低强度有氧运动，以及间歇性的高强度无氧运动时段。比赛分为上下半场，各40分钟，中间有10分钟的休息时间，由两支各有13名球员（6名前锋和7名后卫）的队伍进行对抗。虽然单个球员进行低强度运动的时间超过高强度运动的时长，但高强度运动的性质（包括冲刺、上下半身碰撞和高力量产生）使得比赛的整体强度大幅增加。据显示，单个球员一场比赛的跑动距离约为5000至8000米，并参与20至40次擒抱。据报道，英式橄榄球联盟球员的最大摄氧量（VO2max）值约为56毫升/公斤/分钟，前锋和后卫的值没有差异。然而，前锋的体重、皮下脂肪和去脂体重水平通常高于后卫。后卫比前锋更快，并且在与去脂体重相关时能产生更大的腿部力量输出。关于英式橄榄球联盟球员和英式橄榄球联盟这项运动的生理数据非常有限，该领域未来的研究空间很大。
