Abstract:

The purpose of this study was to determine if varied amounts of running and movement mileage affect overall fitness improvement. Subjects were male U.S. Navy recruits N 1703, 25 divisions, ages 17-35 yr mean age 20.1 - 2.9 yr, who attended boot camp from April 1996 through August 1996. During the first week of training, recruits performed a 1.5-mile run to determine baseline fitness levels. The results from the initial run were compared with a final 1.5-mile run conducted 7 wk later. Based on an age-adjusted fitness scale for a 1.5-mile run time, about one third of the recruits began recruit training in Excellent-Superior condition N 558, one third began in Good condition N 582, and one third began in Poor-Fair condition N 563. Running mileage among divisions ranged from 11.5 to 43.5 miles for the entire 7 wk training period mean 22.7 - 7.2 miles 8-22 run days, mean 13 - 4 days. In addition to running, the divisions accumulated many movement miles 110-202 miles mean 145 - 26 miles while marching in formation. Recruits who began training in Poor-Fair condition improved the most with an average decrease in run time of 155 - 106 min. The Good group improved by 47 - 37 s, and the Excellent-Superior group improved by 17 - 32 s. Conclusion The magnitude of fitness improvement, as measured by run time improvement, was directly related to incoming fitness level but not related to movement mileage or high intensity run mileage accrued during training.
