Perceived treadmill function is correlated with enjoyment of use in trained runners: A user-centred approach

Physical inactivity, a primary cause of most chronic diseases, has been associated with low levels of physical activity enjoyment. Physical activity enjoyment can be impacted by an individual's experience with exercise equipment. The purpose of this study was to adopt a user-centred approach to determine the relationship between physical activity enjoyment and functionality and usability of four treadmills. A running protocol was completed by 57 trained runners (41 male) on four treadmills. Runners reported enjoyment levels as well as their perceptions about treadmill running surface, controls, safety and stability, physical interaction, learnability of data console and aesthetic appeal. Repeated measures ANOVAs showed significant differences between the treadmills for each variable. Multiple regression analysis reported aesthetic appeal significantly predicted enjoyment of use. Results suggest that adopting a user-centred approach to compare exercise equipment usability and features can correlate with enjoyment and further impact on physical activity adherence.
