  METHODS
  Sixty-eight high school girls with a BMI of over 25kg/m² were recruited to participate in this study.

The experimental group received the BodyThink program 6 times, scheduled once a week, with each session lasting 40~50 minutes. Test measures were completed before and after the 6 week intervention period for all participants. Collected data was analyzed using Shapiro-Wilk test, descriptive statistics, χ² test, independent t-test, Mann-Whitney U test with the SPSS/WIN 18.0 program.
  
  
  RESULTS
  The girls in the experimental group significantly improved their results in BMI(Z=-1.67, p=.042), percentage of body fat (Z=-3.01, p=.001), skeletal muscle rate (t=-3.50, p<.001), and self-esteem (t=2.66, p=.005) after the program, compared to the girls in the control group.
