Abstract
Background: Balance is the ability to maintain the center of gravity over the base of support, usually while in an upright position. Balance is a complex function involving numerous neuromuscular processes. The factors having direct influ�ence on the ability to maintain the balancing position may be sensory informa�tion, coordination, range of joint movements and muscle strength. Muscle strength is an important aspect of physical fitness and health status, and a decrease of muscle strength may cause significant functional limitations. This study ai�med to test the effect on postural balance and anti-gravitation muscle strength in women who do Indonesian healthy tera gymnastics.
Subjects and Method: This was a randomized controlled trial carried out in Sura�karta. A total of 160 people 55 to 65 years of age were selected for this study and divided into two groups: (1) Tera gymnastics group; (2) Control group. The depen�dent variables were postural balance and anti-gravitation muscle strength. The independent variable was Indonesian healthy tera gymnastics. Data on postu�ral balance was measured by posturometer, and anti-gravitation muscle strength was measured by dynamometer. The scores between two groups were tes�ted by t-test.
Results: Wobble frequency was lower in the gymnastics group than in the control group, and it was statistically significant. Wobble amplitude was lower in the gym�nastics group than in the control group, and it was statistically significant.
Conclusion: Tera healthy gymnastics is effective to improve postural balance as indicated by low wobble frequency and amplitude.
