The purpose of this study was to assess the effect of 12 weeks of Taekwondo training on body composition, health-related fitness and isokinetic muscle strength in obese women. Thirty obese women aged 35~55 years, participated in this study. They were randomly assigned to a taekwondo training group (n=15), which trained 60 min a day, 3 days per week for 12 weeks, and a control group (n=15). Significant decreases were found for fat mass (p<.05), percent body fat (p<.05), and WHR (p<.001) in training group between pre and post-tests. Taekwondo training improved sit and reach (p<.001), sit-ups (p<.01) and VO2max (p<.01) during the study. Left extensor peak torque (p<.01), left flexor peak torque (p<.0001), left (p<.05) and right flexor total work (p<.01) were increased significantly in training group between pre and post tests. In conclusions, 12 weeks of Taekwondo training program reduced fat mass and percent body fat and improved health-related fitness and isokinetic muscle strength in obese women, which is effective to prevent obesity in middle aged women. Further study has be focused on development of Taekwondo training program to increase lean tissue with concomitant decrease of fat tissue.

Several nutrients are known to affect bone mineral density (BMD). However, these nutrients are combined with food intake and dietary patterns and little is known about the association of dietary patterns and BMD. The objective of this study was to investigate the association of dietary patterns with BMD in Korea Genome Epidemiology Study subjects. Among 2,884 women (40-69 yr) recruited at baseline study (2001), 861 subjects with BMD measurements at baseline and a 4-year follow up study (2005) completed the semi-quantitative food frequency questionnaire. BMD was measured by the Quantitative Ultrasound method. One hundred three food items were combined into 17 food groups and 4 dietary patterns were identified by factor analysis. Cluster analysis using factor score classified each subject into one of three dietary pattern groups named ``Rice and kimchi eating`` (n = 617), ``Contented eating`` (n = 124), and ``Healthy and light eating`` (n = 120). The ``Healthy and light eating`` group, characterized by higher intake of fruit, vegetables, fish, milk and dairy products, and younger age, more exercise, higher education, and higher income than other groups. The tibia BMD of the ``Healthy and light eating`` group was higher than the other groups after adjusting for the age. After the adjustment for the age BMI and exercise, the ``Healthy and light eating`` group showed significantly lower odds of tibia osteopenia/osteoporosis risk compared to the ``Rice and kimchi eating`` group both at the baseline [OR(95% CI) : 0.50(0.30-0.84)] and follow-up [OR(95% CI) : 0.59(0.36-0.97)] examinations. The dietary pattern with low calorie and high intakes of fruit, vegetables, fish, milk and dairy products may have beneficial effects on BMD in middle-aged women.
