N2  - INTRODUCTION: Gait speed is a test to measure functional capacity in older adults. Nevertheless, the factors influencing this variable are not well described in South American populations. <br><br>OBJECTIVE: To determine the relationship between usual and maximal walking speed and functional parameters among Chilean community-dwelling older adults. <br><br>MATERIALS AND METHODS: An observational, descriptive and cross-sectional study including 69 older adults was conducted. The usual and maximal gait speeds were associated with body composition (body mass index), upper limbs muscle strength (arm curl-ups), lower limbs muscle strength (30 seconds sit-to-stand test), global function (Barthel index), ankle flexibility (range of motion), dynamic balance (timed Up & Go test) and aerobic capacity (2 minutes walking test). <br><br>RESULTS: The ankle flexibility, lower limbs strength and aerobic capacity influenced the maximal speed (R2 =0.65; p <0.001), while the usual speed was influenced by upper limbs and lower limbs strength and by the aerobic capacity (R2 = 0.51; p <0.001). <br><br>CONCLUSION: The usual and maximal gait speeds are mostly influenced by the lower limbs muscle strength plus aerobic capacity.<p />  <p>Language: es</p>
