Abstract

|
Purpose: The purpose of this study was to determine the effect of unstable surface strength trainingon balance and lower
extremity muscle activity in elderly women.
Methods: Our study included relatively elderly women age of 65 years or so, 14 elderly women who consented were randomized as two groups, the control group of 7 people, the experimental group of 7 people, unstable surface strength training was performed for 40 minutes a day, twice a week, for a total of 8 week.
Results: The experimental group had a significant difference in OLSTS and OLSTH(p<.05), the control group had a
significant difference in OLSTH(p<.05). And the comparison between two groups had no significant difference (p>.05).
Two groups had no significant difference in TUG (p>.05), the comparison between groups had no significant difference
(p>.05). The experimental group had a significant difference in muscle activity of vastus medialis oblique and vastus
lateralis oblique (p<.05), the control group had a significant difference in muscle activity of vastus lateralis oblique
(p<.05), but the comparison between groups had no significant difference (p>.05).
Conclusion: Unstable surface strength training in elderly women were more effective than general strengthening exercises and it is an appropriate exercise to
prevent from falling in the elderly.
