Sensory Processing Sensitivity and Its Relation to Exercise Behavior and Preferred Exercise Intensity

Background/Objectives: Regular exercise is important for overall health, yet exercise participation in the United States remains low. Exercise promotion depends on identifying factors such as personality that might influence exercise participation. Sensory processing sensitivity (SPS), a personality trait described as the tendency to deeply process environmental stimuli, is a psychological factor that may influence exercise participation. The purpose of this cross-sectional study was to examine relationships among SPS, exercise behavior, and preferred exercise intensity. Methods: Participants (N = 320) were college students and employees who completed the 12-Item Highly Sensitive Person Scale, the Godin Leisure-Time Exercise Questionnaire, and a question related to preferred exercise intensity. Results: Participants' ages ranged from 18 to 70 years (M = 39.36, SD = 15.15), and they were mostly female (69.6%). Most participants were physically active (77.5%). Mean SPS scores were not significantly different between active (M = 50.2, SD = 10.9) and insufficiently active (M = 51.4, SD = 9.97) participants; however, post hoc analysis revealed that the mean increase in SPS score from preference for vigorous intensity to light intensity (5.18, 95% CI [0.13, 10.2]) was statistically significant (p = 0.043). Conclusions: Exercise preferences are an important consideration for exercise adoption and adherence; thus, these findings have practical implications for exercise promotion, especially for individuals who score higher in SPS.
