External workloads associated Hockey 5 s, the new version of youth field hockey, were evaluated in 31 elite U16 male field players (15.4 ± 0.7 years) from three national teams. Mixed-longitudinal observations for the 31 players provided complete data for 33 forwards and 43 defenders. Activities of the players during games were monitored with the GPSports SPI Elite System with a sampling frequency of 10 Hz and were analysed with GPSports Team AMS (version R1 2015.14, Australia). Observed variables did not differ between forwards and defenders, and the three periods of play were differentiated only by maximal speed in the second and third periods. The greatest distances covered were in speed zone 3 (10.0-15.9 km h; 35.5-38.2%) and the smallest in speed zones 4 (16.0-22.9 km h; 14.8-15.6%) and 5 (> 23 km h; 0.4-1.4%). The trends indicated high intensity levels for the entire match and by position and periods. Active time of forwards and defenders accounted for about one-half of a game's duration (~ 15.7 of 30 min). Overall, the Hockey 5s format was highly demanding of players and included relatively short intervals for recovery. The results emphasize the need for preparation that includes specific mixed anaerobic and aerobic training and also the importance of recovery during breaks.
外部工作量与曲棍球 5 相关，这是青少年曲棍球的新版本，在来自三个国家队的 31 名精英 U16 男性曲棍球前锋（15.4±0.7 岁）中进行了评估。对 31 名球员的混合纵向观察为 33 名前锋和 43 名后卫提供了完整的数据。使用 GPSports SPI Elite 系统以 10 Hz 的采样频率监测球员在比赛中的活动，并使用 GPSports Team AMS（版本 R1 2015.14，澳大利亚）进行分析。前锋和后卫之间的观察变量没有差异，只有第二和第三阶段的最大速度区分了三个比赛阶段。覆盖的最大距离在速度区 3（10.0-15.9 km·h；35.5-38.2%），最小的速度区在速度区 4（16.0-22.9 km·h；14.8-15.6%）和速度区 5（>23 km·h；0.4-1.4%）。这些趋势表明整个比赛和根据位置和阶段的高强度水平。前锋和后卫的活跃时间约占比赛总时长的一半（约 30 分钟中的 15.7 分钟）。总的来说，曲棍球 5 格式对球员的要求很高，包括相对较短的恢复间隔。这些结果强调了准备工作的必要性，包括特定的混合无氧和有氧训练，以及在休息期间恢复的重要性。
