Abstract

Background: Obesity has become the main health problem worldwide in children, teen, adult and is influenced by genetic and environmental factors. One of the recommended exercises to prevent obesity is aerobic training such as running. Core training is another form of exercise to do. Purpose: to compare the effect of regular running to combination of regular running and core training on body fat percentage and bone mass. Method: This research is experimental with two groups pre and post test design. Twenty six participants were divided into two groups: 30 minutes running and 30 minutes running with core training. The body fat percentage and bone mass were measured by bioelectrical impedance analysis (BIA). The body fat percentage and bone mass before and after intervension were analyzed using Wilcoxon test, while the difference between intervension were analyzed using Mann-Whitney test. Significance is determined by p value of <0.05 Result: Body fat percentage in the combination training group is significant (p= 0,013) but the running only group shows no significant result with p= 0,649. The difference between both groups is significant (p= 0,07). The bone mass in both groups shows no significant result with p= 0,102. Conclusion: An 8-week combination training program is effective to reduce body fat percentage but does not increase bone mass.
