The relationship between aerobic fitness and recovery from high-intensity exercise in infantry soldiers.
Israel Defense Forces-U.S. Army Conference on Military Medicine. Jerusalem (ISR), 1996/11.
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.
