The purpose of this study was to determine the effects of resistance exercise programs on older adults’ physical and psychological health indicators. Twelve randomized controlled trials published in Korean be-tween January 2000 and July 2024 were included in this meta-analysis. The subjects in the selected studies were all aged 65 and over. The in-tervention group performed resistance exercise, and the control group did not engage in structured exercise programs. The resistance exer-cise programs were implemented for an average of 8–12 weeks, 2–3 sessions per week, with each session lasting 40–70 min. Effect sizes were calculated using standardized mean differences, and statistical analysis was conducted using R software. The results revealed that re-sistance exercise significantly improved various fall-related physical outcomes, including grip strength, flexibility, static and dynamic balance, lower body strength, and coordination. Also, fall efficacy was signifi-cantly increased. However, there was no statistically significant change in skeletal muscle mass and body fat percentage. These findings sug-gest that resistance exercise is an effective intervention for improving physical function and psychological stability in older adults.
