Pushing Shopping Cart: An Intentional Exercise for Older Adults

Abstract

ABSTRACT Physical exertion is a leading barrier to physical activity. Continuing physical activity is vital for older adults because reduced physical activity and lack of regular exercise can lead to muscle weakness and increase the mortality risk. Shopping is an instrumental activity of daily living, and shopping by visiting brick-and-mortar stores can help older adults maintain physical activity. However, if older adults experience significant physical exertion at the store, it could prevent them from engaging in this crucial activity. This study assessed the perceived exertion and heart rate in older women with and without osteoarthritis, pre- and post-pushing a loaded shopping cart. Sixty participants were grouped by age and presence or absence of osteoarthritis. Results from 2(cart conditions) X 2(time) X 3(groups) ANOVA indicated a statistically significant difference in physical exertion and heart rate with and without the cart, pre and post-using the cart, and also between younger and the two older groups; with significantly higher perceived and physiological exertion scores in both groups of older women. Through intentional exercise protocols designed around shopping tasks, there is an opportunity for older adults to engage in physical activity as they shop and build their strength while also improving their well-being.
