The effects of a walking exercise program on fall-related fitness, bone metabolism, and fall-related psychological factors in elderly women.
The purpose of this study was to determine the effects of a 3-month walking exercise program with ankle weights on fall-related fitness, bone metabolism, and fall-related psychological factors. Fall-related fitness was determined from strength, balance, agility, aerobic endurance, muscle mass, and fat mass measures. Bone metabolism was measured using bone density, hormones, and biochemical markers. Fall-related psychological factors included fear of falling and falls efficacy. A 2 × 2 factorial with repeated measures design was used. All subjects were community-dwelling elderly women who volunteered to participate, and randomly were assigned to either an exercise group (n = 11) or a control group (n = 10). Results revealed significant changes in upper body strength, leg strength, aerobic endurance, and body composition. Additionally, hormones and biochemical markers changed significantly over time. Trunk fat and fear of falling changed differently among the two groups. In conclusion, this study suggests that a 3-month walking exercise program with ankle weights may have positive effects on fall-related fitness, bone metabolism, and fall-related psychological factors.
