ABSTRACTThis study investigated changes in body composition in women over 30 (n = 68) after a 12-wk weight training program. A control group (n = 27) was used for comparison of body composition measures only. The experimental group performed 13 exercises 3 days a week for 12 weeks. Initially there were no significant differences in gross body weight, % body fat, FFW, and sum of skinfolds between groups. The experimental group reduced their % body fat and sum of skinfolds while increasing their FFW. There were no significant changes in the controls. To determine the influence of age, the experimental group was subdivided into those under 40 (UF) and those over 40 (OF). Although there were no significant differences in gross body weight between UF and OF at pre or posttests, the UF had significantly lower % body fat and skinfold sums and higher FFW than the OF. As a result of the weight training program, neither age group's gross body weight changed significantly, but both groups significantly decreased their % body fat and increased FFW.
