Older adults must hurry at pedestrian lights! A cross-sectional analysis of preferred and fast walking speed under single- and dual-task conditions.

摘要: Slow walking speed is strongly associated with adverse health outcomes, including cognitive impairment, in the older population. Moreover, adequate crucial to maintain pedestrians' mobility and safety urban areas. This study aimed identify proportion of Swiss adults that didn't reach 1.2 m/s, which reflects requirements cross streets within green-yellow phase pedestrian lights, when fast under challenge. A convenience sample, 120 women (65%) men, was recruited from community (88%) senior residences divided into groups 70-79 years (n = 59, 74.8 ± 0.4 y; mean SD) ≥80 61, 85.5 0.5 y). Steady state assessed single- dual-task conditions at preferred speed. Additionally, functional lower extremity strength (5-chair-rises test), subjective rating, retrospective estimates fall frequency were recorded. Results showed 35.6% younger 73.8% participants not able walk faster than m/s condition. Fast higher compared (all p < .05, r .31 .48). Average single-task 1.19 0.24 (70-79 y) 0.94 0.27 (≥80 y), respectively, correlated performance 5-chair-rises test (rs -.49, .001), (τ .27, -.23, .002). We conclude fitness status many people inadequate safely lights community's daily life Consequently, training measures improve population's physical should be promoted enhance pedestrians.
