RESUMEN
This descriptive cross-sectional mixed methods study conducted in Singapore aimed to describe community-dwelling older adults' differences in physical activity (PA) based on perceived safety to exercise, barriers to PA, and preferred modes of PA during a pandemic. Out of 268 older adults, 25.4% felt unsafe to exercise during the pandemic. More participants who felt unsafe were aged 75 years and older (72.1% vs. 57.0%, p = .028) and lacked formal education (54.4% vs. 37.0%, p = .040). Barriers included difficulties exercising with masks, family concerns, and exercise center closures. Those who felt unsafe were significantly more likely to exercise at home and had significantly shorter duration of exercise and walks per week (2.72 vs. 4.50 hr, p = .002). Perceived barriers and exercise preferences should be considered when developing programs to improve older adults' PA during pandemics.
