ABSTRACT
The decrease of balance capacity is considered as a high risk factor of fall accident, so it is important for the middle-aged and elderly people to keep balance capacity on a high level. In this study, we investigated the effects of aqua exercise on dynamic and static balance function. Thirty-two middle-aged women (56.6±8.1 years) participated a 60-min aqua exercise program three times per week for eight weeks. After exercise intervention, body weight, body mass index, grip strength, side step, shuttle stamina walking test were significantly improved (p<0.05-0.001). Functional reach (p<0.001) and total length of centroid shake with eye close condition (p<0.05) was significantly improved, but with eye open condition was not changed. However, when we evaluate the total length of centroid shake by T-score, static balance performance with eye open and close condition was significantly (p<0.05) improved in the below average groups. In addition, measurement value of functional reach was also improved in these groups. These results indicate that aqua exercise benefits not only physical muscle strength and endurance capacity, but also balance function in middle-aged women. Particularly aqua exercise is more effective for the subjects with lower static balance function before intervention.
ABSTRACT
Balneotherapy includes several modalities of treatments and wellness programs, such as physiological and pharmacological effects of hot spring bathing and aqua-exercise, relaxing and biorhythm adjusting effects of staying in the urban climates and educational instruction for healthier life style. We examined health promoting effects of the comprehensive balneotherapy as a whole by the randomized controlled study. 89 women, who had no medical care, and were aged 40-65 years (mean +/- SD age: 59.0 +/- 8.0 years), volunteered for this investigation. Subjects were assigned at random to three groups; group 1 was the control group without any intervention; group 2 with exercise for 60min and educational guidance; group 3 with exercise for 30min and balneotherapy including aquaexercise for 30min and bathing in hot spring for 30min in addition to educational guidance. Each group followed the prescribed program twice a week for 3 months. There was no significant difference in age, body mass index (BMI), blood pressure, heart rate, %FAT, diet/exercise custom and psychological conditions among the three groups. Before and after the program, the physiological, biochemical and psychological measurements were performed: body weight, blood pressure, heart rate, physical strength using ergometer, serum lipids, liver function and questionnaires with profile of mood state (POMS) and self relating depression scale (SDS). After excluding 4 subjects who were dropped out because of their convenience, the results were compared. In group 2 (N=28) and 3 (N=28), body weight, BMI, blood pressure and heart rate were significantly decreased and their physical strength and psychological condition were improved significantly (p<0.05). Furthermore only in group 3, serum total cholesterol, atherogenic index and triglyceride were significantly decreased (p<0.05). The difference between these two groups was not due to changing of their diet and estimated energy consumption by daily activities during 3 months. These data suggest the efficacy of balneotherapy with hot spring bathing and aqua-exercise for health promotion.
