Outdoor gyms and physical function: A cross-sectional comparative study between active and sedentary older adults.

Outdoor gyms (OG) are public places designed for physical activity, especially for older adults. This is a cross-sectional study that aimed to compare morphofunctional characteristics of sedentary and active older adults regarding OG. The participants consisted of 194 older people divided into three groups: sedentary (n = 76, mean age = 70.5 ± 6.4 years, 38.7% male); OG + walking (n = 86; mean age = 69 ± 6.1 years; male 50.6%); and OG (n = 32; mean age = 70.3 ± 8.3 years; male 56.3%). Socioeconomic and morphofunctional characteristics, anthropometric measurements, body composition, and functional tests were collected. For comparison among groups ANOVA, for categorical variables the chi-square test or Fisher's exact test, and to verify factors related to gait speed logistic regression were used. We found that sedentary older adults had lower educational level and lower prevalence of polypharmacy. OG + walking participants had lower waist circumference and fat percentage, and better gait speed. Older people in the OG + walking were less likely to show gait difficulty (i.e., <1.0 m/s) in reference to the sedentary group. In addition, strength and better performance on the Timed Up and Go were also associated with gait speed >1 m/s. It is understood that the higher volume of physical activity performed by OG + walking may be one of the reasons why they obtained better indicators in health aspects. The findings, especially regarding the characterization of profiles of older adults who use OG, leads to the definition of public policies aimed at the real needs of this public.
