Does physical activity enjoyment mediate the association between exercise motivation and physical activity in patients with heart failure?
Physical activity enjoyment completely mediates the relationship between exercise motivation and physical activity in heart failure patients, suggesting that motivation alone is insufficient without enjoyment.
p-value: p=<.01
Objective To determine whether physical activity enjoyment mediated the association between motivation and physical activity in patients with heart failure. Design and setting A cross-sectional study at the cardiology clinic in the university hospital in Valencia, Spain Subjects A total of 134 patients with heart failure. Main measurements Physical activity was assessed with the International Physical Activity Questionnaire, motivation was assessed with the Exercise Motivation Index and Physical Activity Enjoyment was assessed with the Physical Activity Enjoyment Scale. Analysis Mediation analysis using Hayes’ PROCESS macro (Model 4) for SPSS. Results The mean age of the sample was 70 ± 14 years, 47 patients were female (35%), and 87 patients were in New York Heart Association I/II (67%). A positive relationship was found between exercise motivation and physical activity ( t = 4.57, p < .01) and physical activity enjoyment ( t = 11.52, p < .01). Physical activity enjoyment was found to positively affect physical activity (t = 3.50, p < .01). After controlling for physical activity enjoyment, the effect of exercise motivation on physical activity changed from a significant to non-significant ( t = 1.33, p = .89), indicating that enjoyment completely mediated the relationship between motivation and physical activity. Overall, 25% of the variation in physical activity was explained by the mediation model. Conclusions Physical activity enjoyment mediates the relationship between exercise motivation and physical activity in patients with heart failure. This means that even highly motivated heart failure patients may not be physically active if they do not enjoy the physical activity.
Klompstra et al. (Thu,) conducted a cross-sectional in heart failure (n=134). Exercise motivation was evaluated on Physical activity (p=<.01). Exercise motivation's effect on physical activity was completely mediated by physical activity enjoyment in patients with heart failure, explaining 25% of the variation.
