Abstract

Introduction: Physical activity is known to improve many aspects of health including physical and psychological well-being. Additional psychological health benefits have been attributed to performing physical activity outdoors. Despite this potential benefit, objectively measured outdoor physical activity has rarely been studied in an adult population.

Purpose: The purpose of this study is to objectively define and measure bouts of outdoor physical activity and investigate correlations between this activity and subjectively reported psychological stress and anxiety.

Methods: Objective outdoor physical activity will be measured using accelerometry and optic sensor capabilities of ActiGraph GT3X devices. Bouts of moderate-to-vigorous physical activity will be determined using validated ranges of activity counts4 and lux values from the optic sensors will determine environment. Outdoor physical activity bouts will be defined as periods of moderate-tovigorous physical activity of at least 10 minutes with average lux values of at least 2405. Participants will complete baseline questionnaires of trait anxiety and perceived stress followed by a 10 consecutive day wear time of the ActiGraph GT3X devices. Results: Data collection and processing are currently underway. Measures of outdoor physical activity will be summarized and presented along with correlations between this activity and measures of trait anxiety and perceived stress.

Conclusions: This will be the first study to objectively measure and define outdoor physical activity bouts in adults using simple accelerometers with optics capabilities. This definition and methodology can be used to investigate further associations between outdoor physical activity and measures of psychological health as well as a tool to objectively validate outdoor physical activity to be studied as an assigned intervention.

Objective Assessment of Outdoor Physical Activity in College Students and Relationships to Psychological Well-Being
