Regular physical activity is known to increase lifespan, prevent chronic diseases,improve cognitive maintenance, increase self-efficacy, decrease mortality, and reducerisk of falls in older adults. 60% of older adults report not participating in regularphysical activity or exercise; however, new research is suggesting that older adults aremeeting the American Heart Association physical activity recommendations throughouttheir daily activity. Sleep quality, quantity, and waking behaviors have been associatedwith increased quality of life, improved health, and increased overall energy expenditure.However, research has not looked at how structured versus unstructured physical activityaffects sleep behaviors and perceived quality. This study examines current structuraltendencies of physical activity in older adults to assess if they are meeting the AmericanHeart Association recommendations through measuring daily energy expenditure(kcal/day). In addition, the study also examines how physical activity structure and sleepquality are correlated through direct and perceived assessments. Forty-five older adultsfrom the Charlotte community volunteered and were divided into groups based on currentstructure of physical activity they engage in (i.e instructed exercise, independent exercise, physically active lifestyle, or control). Energy expenditure and sleep quality weremeasured through a wrist worn Fitbit Charge HR that was worn for 7 days. Perceivedhealth status and sleep quality were assessed through surveys, SF-36 & PSQI,respectively. No differences were observed between groups for energy expenditure, sleep quality, or sleep efficiency. Analysis of variance showed statistical significance betweenthe physically active lifestyle group and the other groups for pain (p = 0.002), andphysical functioning (p = 0.01). Trends toward statistical significance were observed withperceived health perception (p = 0.07) and steps (p = 0.07) between groups. The currentstudy suggests that energy expenditure and sleep quality are not related to structure ofphysical activity in older adults.
