This analytic decision was made because the highly skewed nature of the physical activity data would violate the assumptions of linear regression regarding the normality of the outcome variable. Future research in more active populations would likely reduce the skewed nature of physical activity data and allow researchers to explore associations between affect and feelings of energy and average daily minutes of physical activity as a continuous variable. With regard to determining whether a participant was meeting physical activity guidelines, minutes of MVPA were considered but bout length was not.
