Abstract

BACKGROUND
The purpose of this study was to examine the effect size analysis of an exercise program on body composition, blood pressure, and physical fitness in Korean adults.
METHODS
The subjects were 1,095 adults (men=76, women=1,019) older than 19 years who participated in the Fitness Promotion program at the centers for National Fitness Award Program in 2012. The subjects performed the regular combined exercise for 60-90 minutes per day, 2-4 days a week for 8 weeks. And the intensity of the exercise program was moderate (55-80% of maximum heart rate). In this study the effect size (ES) was calculated by the Cohen (1988) method.
RESULTS
The ES was 0.06-0.11 (average small ES) for body composition, 0.52-0.77 (average large ES) for blood pressure, and 0.08-0.48 (average medium ES) for physical fitness variables.
CONCLUSIONS
The estimated ES would be a useful reference to determine sample size for post-exercise experimental research.
