Aquatic exercise for improving immune function and mental stress in pre-frailty elderly women.

We aimed to investigate the effect of aquatic exercise on immune response in pre-frailty elderly women. Forty pre-frailty elderly women were recruited from the Community Center. The 12-week supervised aquatic exercise program intervention consisted of 3 days per week. IgA, IgG, and IgM were significantly increased, and IgE was significantly decreased in the exercise group. Tension-anxiety, depression, and confusion were significantly decreased, and anger-hostility was significantly increased in the exercise group. This study indicates that an aquatic exercise is an effective lifestyle intervention strategy for improving immune function and mood state in pre-frailty elderly women.
