title: Description of exercise participation of adolescents with cerebral palsy across a 4-year period.
abstract: OBJECTIVE
  The purposes of this study were to describe (1) the types of exercise participation of adolescents with cerebral palsy; (2) the weekly duration of stretching, strengthening, and cardiovascular exercise; (3) how the level of activity compares with national health guidelines; and (4) the change in participation over 4 years.
  
  
  METHODS
  Participants included 126 males and 104 females (mean age = 14.7 years, SD = 1.7 years) who reported physical activities in the previous week. Analyses included frequency counts and proportions, stacked bar graphs, and 2-way analyses of variance of exercise participation by Gross Motor Function Classification System (GMFCS) and sex.
  
  
  RESULTS
  A significant main effect of GMFCS level was detected for light and moderate exercise. A significant interaction of GMFCS level and sex was found for stretching; females stretched more. An average of 9.4% and 11.4% of our sample participated in weekly levels of moderate and vigorous exercise, respectively.
  
  
  CONCLUSIONS
  Pediatric physical therapists should promote increased exercise participation rates among youths with cerebral palsy.
