title: Relations between anhedonia and physical activity.
abstract: OBJECTIVE
  To examine the relation of 2 measures of anhedonia-a specific facet of depression indicative of inability to experience pleasure-to physical activity (PA).
  
  
  METHODS
  Cross-sectional correlational survey study of 157 college students (73% female, M  age 19.9 years).
  
  
  RESULTS
  One or both measures of anhedonia were inversely associated with walking frequency, moderate-intensity PA frequency and duration, and vigorous-intensity PA frequency and duration (βs -16 to -.27, Ps < .05). Some of these associations were statistically  mediated by lower PA enjoyment.
  
  
  CONCLUSIONS
  Deficient pleasure may be an important affective mechanism underlying PA behavior.
