Abstract:
This study was designed to investigate the effects of 8-week resistance exercise by using dumbell on the body composition, serum hormone profiles and feeding patterns in young and healthy female students with over 30% of body fat, aged 22 years in Masan, Korea. The subjects were all six, performed successfully the entire exercise-program. Anthropometry, serum lipid and neurohormone profiles of subjects were analyzed at 0, 4 and 8 weeks after exercise. And also their food and nutrient intakes were self-reported by 3-day record and food frequency questionnaire. Triceps skinfoldthickness of the subject students significantly reduced after the exercise to 46% less than before (p < 0.002). The serum concentrations of leptin, insulin and catecholamine appeared to decrease steadily, but not significantly. Total protein in serum increased significantly (p < 0.05), and Na (p < 0.005), K (p < 0.001) and Fe (p < 0.058) concentrations increased remarkably within the normal range. The 8-week resistance exercise tended to induce fiber consumption (p < 0.089) of subject students and changed the P/M/S ratio changed into the desirable way from 0.8 : 1 : 1 to 1 : 1 : 1, and that of n- 6/n-3 PUFA from 11 : 1 to 6 : 1. After taking exercise, the intake frequency of cookies (p < 0.058) and raymeun (p < 0.085) decreased, but finally this feeding pattern returned to the way as before even though at marginal significance. Consequently the resistance exercise may induce the desirable changes of body fat and improve serum lipid profiles and feeding patterns in young obese females.
