12주간의 맞춤형 전신 저항성 운동이 비만 청년의 신체조성과 밸런스에 미치는 영향 분석

초록

This study aimed to analyze the effects of a 12-week personalized full-body resistance training program, conducted twice weekly, on body composition and balance ability in 134 young adults aged 20–34 years. Participants were selected through the Korean Ministry of Health and Welfare's youth physical health promotion program in Dea-gu and underwent a one-on-one tailored exercise intervention at National K University. The program was designed based on participants’ physical characteristics and fitness levels. The intervention consisted of warm-up, main exercise, and cool-down phases, lasting a total of 55 minutes per session. Warm-ups included cycling or treadmill exercises, while the main exercise comprised progressive full-body strength training targeting both upper and lower body muscles. Cool-downs were performed using foam rollers for myofascial release. The results were as follows. First, in terms of body composition, males showed a significant decrease in body fat mass (p<.05) and a significant increase in muscle mass (p<.05), although changes in body weight were not statistically significant (p>.05). In females, significant decreases were observed in body fat percentage and BMI (p<.05), along with a significant increase in muscle mass (p<.05). Second, balance ability significantly improved in both males and females after the intervention (p<.001). This study demonstrates that a personalized full-body resistance training program effectively improves body composition and balance ability in young adults. These findings can serve as foundational data for health promotion and the enhancement of physical performance.
