Abstract
BACKGROUND: Menopause is associated with an age-related increase in the risk of cardiovascular and a decline in muscular strength. Aerobic exercise has been recommended in order to alleviate the harmful effects during the post-menopausal period.
OBJECTIVES: To investigate the effects of the nine-square exercise on blood pressure and leg strength of post-menopausal women.
METHODS: The 6-week study was conducted with 20 post-menopausal women in the age range of 50-59 years. Participants were randomly allocated into 2 groups. Firstly, the Exercise Group consisted of 10 menopausal women, who performed the nine-square exercise with moderate intensity for 40 minutes/day for 5 days/week. Secondly, there was a Control Group, consisting of 10 menopausal women, who had been asked to maintain their routine physical activity. The resting blood pressure and five times sit-to-stand test were measured at the baseline and at Week 6. The data was analyzed by using the Paired t-tests and the Student t-test.
RESULTS: The average age of participants was 55.4±3.0 years, while the initial systolic blood pressure was measured at 124.4±8.8 mmHg. After 6 weeks of performing the nine-square exercise, the systolic blood pressure had been reduced by 8 mmHg (115.9±7.9 mmHg: p<0.001). In addition, there had been a significant decrease in the amount of time to complete five times sit–to-stand test when compared with control group at 13% (control group 6.9±0.7 sec, exercise group 5.9±0.5 sec).
CONCLUSIONS: The nine-square exercise had been able to help control resting blood pressure and improve leg strength in post-menopausal women.
