Changes in Physical Activity Barriers among American Indian Elders: A Pilot Study​.

Abstract

The objective of the present study was to assess whether selfreported physical activity barriers could be reduced among American Indian elders who participated in a 6-week randomized physical activity trial that compared the use of a pedometer only to that of pedometers with step-count goal setting. Elders (N = 32) were compared on the Barriers to Being Physically Active Quiz after participating in a pilot physical activity trial. Elders were classified into high- and low-barrier groups at baseline and compared on self-reported physical activity, health-related quality of life, pedometer step counts, and 6-minute walk performance. At the conclusion of the 6-week trial, only the lack of willpower subscale significantly decreased. The low-barrier group reported significantly higher physical activity engagement and improved mental health quality of life than the high-barrier group. The groups did not differ on daily step counts or 6-minute walk performance. Additional research is needed with a larger sample to understand relevant activity barriers in this population and assess whether they can be modified through participation in structured physical activity and exercise programs.
