Objectives

Some researchers speculate that changes in body composition with strength training are due to increases in physical activity levels outside of training. To test this theory, 21 sedentary men & women 65-75 years of age were studied before and after a 24 week (3 times per week) total body strength training program using Keiser machines. Total daily physical activity and estimated energy expenditure were recorded during a 4 day period at the beginning, middle, and end of training.

Results

Both men and women substantially increased their 1 repetition maximum strength, and significantly increased their fat free mass. However, there were no significant changes in percent body fat. Total daily physical activity and estimated energy expenditure did not change significantly for the overall sample or within each gender. Some increases were noted in the resting metabolic rate of the men only.

Summary

Changes in body composition with strength training do not appear to be connected to increases in physical activity levels outside of training. Therefore the changes are a direct result of the strength training program.
