Abstract
This study with 39 healthy elderly people as subjects, aimed to reveal the relationship between dynamic balance and standard leg extension strength, right and left leg differences and gender, and to compare the leg extension strength to the knee extension muscle strength. We used StrengthErgo240 (SE24) to measure the leg extension strength, the Functional Reach Test, Time Up and Go and gait speed for dynamic balance, and a hand held dynamometer for the knee extension strength. Right and left leg differences were revealed in the leg extension strengths of females and showed a significant correlation with knee extension strength. Also, leg extension strength significantly correlated with dynamic balance in both sexes, suggesting that as an open kinetic chain the leg extension strength is more strongly correlated with dynamic balance than the knee extension strength.
