The relationship between aerobic fitness and recovery from high-intensity exercise was examined in 197 infantry soldiers. Aerobic fitness was determined by a maximal-effort, 2,000-m run (RUN). High-intensity exercise consisted of three bouts of a continuous 140-m sprint with several changes of direction. A 2-minute passive rest separated each sprint. A fatigue index was developed by dividing the mean time of the three sprints by the fastest time. Times for the RUN were converted into standardized T scores and separated into five groups (group 1 had the slowest run time and group 5 had the fastest run time). Significant differences in the fatigue index were seen between group 1 (4.9 +/- 2.4%) and groups 3 (2.6 +/- 1.7%), 4 (2.3 +/- 1.6%), and 5 (2.3 +/- 1.3%). It appears that recovery from high-intensity exercise is improved at higher levels of aerobic fitness (faster time for the RUN). However, as the level of aerobic fitness improves above the population mean, no further benefit in the recovery rate from high-intensity exercise is apparent.
对197名步兵进行了有氧适能与高强度运动恢复之间关系的研究。通过2000米全力跑(RUN)来测定有氧适能。高强度运动由三次连续的140米冲刺组成,其间有几次方向变化。每次冲刺之间有2分钟的被动休息。通过将三次冲刺的平均时间除以最快时间得出疲劳指数。RUN的时间转换为标准化T分数,并分为五组(第1组跑步时间最慢,第5组跑步时间最快)。第1组(4.9±2.4%)与第3组(2.6±1.7%)、第4组(2.3±1.6%)和第5组(2.3±1.3%)之间的疲劳指数存在显著差异。似乎有氧适能水平较高时(RUN时间更快),高强度运动后的恢复情况会得到改善。然而,当有氧适能水平高于总体均值时,高强度运动恢复率并无进一步明显益处。
