높은 지도 비율의 전신진동운동이 비만 중년여성의 신체조성, 기초체력, 혈중지질에 미치는 영향

Abstract

The purpose of this study to examine the effect of 8 weeks of whole body vibration exercise (WBVE) on body composition, physical fitness and blood lipid profiles in middle-aged overweight women. We recruited overweight participants (over 45 years, BMI 25 kg/㎡, or % body fat 32%, n=16), and randomly assigned them to either the control group (Con, n=8) or the exercise group (Ex, n=8). All participants underwent the evaluation for body composition, physical fitness and blood lipid profiles before and 8 weeks after the interventions. The Ex group performed the WBVE for 40 min/day, 3 days a week for 8 weeks. The WBVE comprised of standing, squat, heel rise, and push-up positions, and the frequency and amplitude are controlled for an incremental overload exercise. The interaction effect was significantly different in the health-related fitness (muscle strength and endurance, cardiovascular endurance, flexibility, and percent of body fat) and the skill-related fitness such as agility and single-leg balance after 8 weeks of intervention relative to the baseline of the Con and Ex groups. In addition, the WBVE for 8 weeks significantly increased HDL-cholesterol and decreased body weight. These results suggest that WBVE program induces improvement of physical fitness and obese factors in middle-aged overweight women. Therefore, the WBVE might be an effective exercise method to promote physical fitness and weight loss in middle-aged overweight women.
