AB  - BACKGROUND: Exercise has increasingly been proposed as a healthful intervention 
      prior to and after the onset of psychosis. There is some evidence to suggest that 
      youth at clinical high risk (CHR) for psychosis are less physically active and 
      report more barriers to engaging in exercise; however, there has been relatively 
      limited empirical work documenting this phenomenon, and to date, relationships 
      between physical activity, barriers, and clinical phenomenology have been 
      unclear. METHODS: CHR (N = 51) and healthy control (N = 37) participants 
      completed a structured clinical interview assessing attenuated psychotic symptoms 
      and substance use, and an exercise survey that assessed current exercise 
      practices, perceived physical fitness, and barriers related to engaging in 
      exercise. RESULTS: CHR youth engaged in less physical activity, exhibited lower 
      perception of fitness, and endorsed more barriers related to motivation for 
      exercise. The CHR group showed significant negative correlations where lower 
      perceptions of fitness were associated with increased negative, disorganized, and 
      general symptoms. Decreased frequency of activity was related to more barriers of 
      motivation. Interestingly, greater symptomatology in the CHR group was associated 
      with more barriers of self-perception and motivation for engaging in exercise. 
      However, findings suggested a nuanced relationship in this area; for example, 
      increased physical activity was associated with increased substance use. 
      CONCLUSIONS: The results of the current study support the notion that sedentary 
      behavior is common in CHR youth, and more broadly, provide an impetus to target 
      motivation through supervised exercise and fitness tracking to promote the health 
      and well-being of CHR individuals.
