Abstract

This paper, the second of a two-part paper, reports results from an experimental study conducted to understand physical activity patterns, and determine the effect of age on physical activity patterns in older Mexican American adults. The Yale Physical Activity Survey was administered to 49 older Mexican American adults (42 females and seven males), aged 68-80 years, recruited from senior recreation centers in the city of El Paso. Based on participant responses to questions about the type and duration of different types of physical activities, overall physical activity indices including the total time (h/week), the total energy expenditure (kcal/week), a summary index score, a vigorous activity score (units/month), a leisurely walking score (units/month), a moving score (units/month), and a standing and sitting score (both in units/month) were computed. These responses were then regressed with age (as the predictor variable). Since the number of older males in the study was small, data from men and women were combined. Results indicate that the standing score index (ppRelevance to industryUnderstanding physical activity patterns (both work and leisure activities in daily living) in older adults is important for estimation of activity metabolism for among older adults.
