  • Muscle strength and mobility decrease with age. Strengthening exercise can prevent decreased muscle strength and mobility. The purpose of this study is to evaluate the effects of home-based Quadriceps femoris strengthening exercise in elderly subjects and its correlation with functional mobility, measured using Timed Up and Go (TUG) test. Thirty-three subjects aged 60 years and above were analyzed in this study. Quadriceps femoris strength was determined using ankle weights that give a perception of “somewhat hard” in Borg Scale after 10 repetitions. Exercise was done at home three times a week, in 3x10 repetitions. TUG test and ankle weights was re-examined on 4th and 8th week. Initial quadriceps strength was 1,4 (0,4) kg. After 4 weeksof exercise, there was 46,61% increment to 2,0 (0) kg and after 8 weeks 95,91% increment was recorded with ankle weight of 2,6 (0,6) kg. TUG test at initial was 11,3 (1,4) seconds. After 4 weeks, TUG improved to 10,0 (1,3) seconds and after 8 weeks to 9,33 (1,40) seconds. Modest correlation (r=-0,354) was recorded between Quadriceps femoris strength improvement and TUG improvement. Quadriceps femoris strengthening exercise can improve muscle strength and mobility in elderly.Keywords: elderly, TUG, muscle strength, quadriceps femoris, home based strengthening exercise.
