12주간 피클볼 운동이 비만 중년남성의 신체구성, 지방대사 및 인슐린 저항성에 미치는 효과 = The Effects of a 12-Week Pickleball Exercise Program on Body Composition, Lipid Metabolism, and Insulin Resistance in Obese Middle-Aged Men

다국어 초록 (Multilingual Abstract)

Purpose: The purpose of this study was to explore the feasibility of pickleball as an exercise intervention for improving metabolic health in obese middle-aged men and to examine the effects of a 12-week pickleball exercise program on body composition, lipid metabolism, and insulin resistance.
Methods: A pretest–posttest control group experimental design was employed. Twenty-seven obese middle-aged men participating in a regular lifelong learning program at a lifelong education center in Gyeonggi-do, Korea, were assigned to either an exercise group (n=13) or a control group (n=14). The exercise group participated in a 12-week pickleball exercise program. All variables were measured before and after the intervention.
Results: After the intervention, body weight and body fat mass significantly decreased in the exercise group, whereas fat-free mass, muscle mass, and body mass index showed no significant changes. With respect to lipid metabolism, triglycerides and low-density lipoprotein cholesterol significantly decreased, while total cholesterol and high-density lipoprotein cholesterol showed no significant changes. In addition, fasting plasma glucose, fasting insulin, and homeostasis model assessment of insulin resistance were significantly reduced.
Conclusion: These findings indicate that a 12-week pickleball exercise program is an effective exercise intervention for reducing body fat, improving lipid metabolism, and decreasing insulin resistance in obese middle-aged men. Pickleball may serve as a practical and sustainable exercise modality for promoting metabolic health in this population.
