Response of 40 and Over Aged Military Personnel to an Unsupervised, Self-Administered Aerobic Training Program,
Abstract
The Army recently extended mandatory physical training and testing to include personnel 40 yrs of age and older. The purpose of this study was to describe the profile of aerobic fitness in a representative group from this age population and to evaluate the response of such a group to a self-administered, unsupervised training program. Maximal oxygen uptake (VO2 max) and percent body fat (%BF) were assessed in 295 military personnel (40-53 yrs of age) before and after 6-months of physical training consisting of a progressive walk/run mode of exercise. The mean + or - SD for VO2 max and %BF for all subjects was 38.1 + or - 6.2 ml/kg min and 26.1 + or - 4.7%, respectively. Subjects were divided into three groups based upon their initial level of physical activity determined by interview as follows: inactive, moderately active and active. Upon retesting after 6 months, 40% of the inactive group had not participated to any appreciable degree in the program and subjects of this group who did participate showed only a slight and insignificant increase (4.4%) in VO2 max. The pretraining level of VO2 max for the total population studied was similar to that reported in other studies on comparably aged subjects. However, changes with training were well below those seen with supervised group programs of 6 months duration.
