To describe the repeated-high-intensity activity and internal training load of rugby sevens players during international matches and to compare the differences between the 1st and 2nd halves.
Twelve international-level male rugby sevens players were monitored during international competitive matches (n = 30 match files) using global positioning system technology and heart-rate monitoring.
The relative total distance covered by the players throughout the match was 112.1 ± 8.4 m/ min. As a percentage of total distance, 35.0% (39.2 ± 9.0 m/min) was covered at medium speed and 17.1% (19.2 ± 6.8 m/min) at high speed. A substantial decrease in the distance covered at >14.0 km/h and >18.0 km/h, the number of accelerations of >2.78 m/s and >4.0 m/s, repeated-sprint sequences interspersed with ≤60 s rest, and repeated-acceleration sequences interspersed with ≤30 s or ≤60 s rest was observed in the 2nd half compared with the 1st half. A substantial increase in the mean heart rate (HR), HRmax, percentage of time at >80% HRmax and at >90% HRmax, and Edwards training load was observed in the 2nd half compared with the 1st half.
This study provides evidence of a pronounced reduction in high-intensity and repeated-high-intensity activities and increases in internal training load in rugby sevens players during the 2nd half of international matches.
描述七人制橄榄球国际比赛中球员的重复高强度活动和内部训练负荷，并比较上下半场所存在的差异。
使用全球定位系统技术和心率监测对 12 名国际水平的男子七人制橄榄球运动员在国际比赛期间（n=30 场比赛）进行监测。
球员在整个比赛中相对总距离为 112.1±8.4 m/min。以总距离的百分比表示，35.0%（39.2±9.0 m/min）的距离为中速，17.1%（19.2±6.8 m/min）的距离为高速。与上半场所比，下半场所覆盖的 >14.0 km/h 和 >18.0 km/h 的距离、>2.78 m/s 和 >4.0 m/s 的加速度次数、≤60 s 休息时间间隔的重复冲刺序列和≤30 s 或≤60 s 休息时间间隔的重复加速序列均显著减少。与上半场所比，下半场所观察到平均心率（HR）、HRmax、>80% HRmax 和 >90% HRmax 的时间百分比、以及爱德华兹训练负荷均显著增加。
本研究为国际比赛中七人制橄榄球运动员在下半场所呈现的高强度和重复高强度活动明显减少，内部训练负荷增加提供了证据。
