摘要：Background and Purpose: Although physical activity (PA) is important for all ages including older adults, participation may be influenced by weather variation and access to programming. Our primary aim was determine if PA participation is influenced by season and place of residence. A secondary aim was to compare objective and subjective measure of PA participation. Methods: Participants included older individuals (age>65) living in a residential retirement community (RR) with access to an on-site fitness facility (n=7) and additional volunteers (n=9) who lived at home and traveled to exercise at a non-residential community (NR) activities center Accelerometers were used to measure daily PA during the summer and again during the winter. Results: PA for the NR group was higher in the summer (268.4±73.7 min vs. RR=186.8±68.0, p=0.039), but not in the winter (NR=261.8±92.6 min, RR=182.0±72.5, p=0.082). No within-group change in PA was noted from summer to winter for either group (p>0.05). The correlation between subjective and objective measures of PA was low (r=.262). Conclusion: Access to appropriate facilities and programming serves to help older individuals maintain PA levels despite seasonal weather variations. The low correlation between objective and subjective measures suggest a need to re-evaluate methods of tracking PA participation by older adults.
