The purpose of this study was to examine for the first time the match running demands and heart rate (HR) responses associated with elite rugby sevens referees. Twelve referees were analyzed over 38 games, using Global Positioning System. Referees covered an average distance of 1665.2 ± 203.5 m per game (15.1 ± 0.5 minutes). Over this distance, 22.3% (371.8 ± 48.9 m) was spent standing and walking, 25.9% (431.2 ± 92.6 m) jogging, 12.4% (206.5 ± 53.2 m) cruising, 23.8% (395.6 ± 94.3 m) striding, 8% (133.3 ± 61.6 m) high-intensity running, and 7.6% (126.7 ± 87.3 m) sprinting. The average maximal distance of sprints, the number of sprints, and the mean sprint distance over the game were 31.3 ± 13.4 m, 5.76 ± 3.6 sprints, and 19.9 ± 7.8 m, respectively. The referee's work-to-rest ratio was 3.5:1. There were no statistical differences between the first and second half in any of the running variables analyzed. The average HR in the second half (160 ± 9 b·min(-1); 86 ± 5% maximal heart rate (HRmax) of the estimated) was higher (p < 0.05) than the HR recorded in the first half (154 ± 11 b·min(-1); 83 ± 6% of the estimated HRmax). This study also suggests that the physical demands of referring in rugby sevens are quite different from those encountered in other rugby codes, and the training regimes need to meet the increased overall running demands and high-intensity running activity.
本研究旨在首次检验精英七人制橄榄球裁判的比赛跑动需求和心率（HR）反应。对 12 名裁判在 38 场比赛中的数据进行了分析，使用了全球定位系统。裁判每场比赛平均跑动距离为 1665.2 ± 203.5 m（15.1 ± 0.5 分钟）。在这段距离内，22.3%（371.8 ± 48.9 m）是站立和行走，25.9%（431.2 ± 92.6 m）是慢跑，12.4%（206.5 ± 53.2 m）是巡航，23.8%（395.6 ± 94.3 m）是大步跑，8%（133.3 ± 61.6 m）是高强度跑，7.6%（126.7 ± 87.3 m）是冲刺跑。平均最大冲刺距离、冲刺次数和每场比赛的平均冲刺距离分别为 31.3 ± 13.4 m、5.76 ± 3.6 次和 19.9 ± 7.8 m。裁判的工作与休息比为 3.5:1。在分析的所有跑动变量中，上半场和下半场之间没有统计学差异。下半场的平均心率（160 ± 9 b·min(-1)；86 ± 5%最大心率（HRmax）估计值）更高（p < 0.05）比上半场记录的心率（154 ± 11 b·min(-1)；83 ± 6%最大心率（HRmax）估计值）。本研究还表明，七人制橄榄球裁判的身体需求与其他橄榄球比赛截然不同，训练方案需要满足整体跑动需求和高强度跑动活动的增加。
