The relation between muscle strength and balance in elderly individuals enrolled in a balance program

Abstract

Introduction: Several factors may be associated with an increased risk of falls as age increases. Lower limb strength (LLS), which may be trained for, has drawn the attention of researchers in the field of physical education. Objective: To analyze the relation between balance and LLS in elderly participants enrolled in a program aimed at preventing falls. Methods: The sample consisted of 32 elderly persons enrolled in an extension project. Their mean age was 76.54 (± 8.3) years. The following tests were conducted: sit and stand (LLS), one-leg stance (static balance), TUG (dynamic equilibrium), and functional reach (recoverable balance). The statistical analysis was carried out by means of Spearman correlation (p<0.05) between LLS and three variables: one-leg stance, TUG, and functional reach. SPSS 18.0 software was used. Results: Test averages were: LLS – 15.6 (± 5.86), one-leg stance – 15.71 (± 11.82), TUG – 6.03 (± 1.84), functional reach – 32.84 (± 6.26). Statistically significant correlations were revealed between LLS and one-leg stance, TUG, and functional reach. Conclusion: Muscular strength training for the elderly can improve balance and help prevent falls.
