title: Physical activity variety, energy expenditure, and body mass index.
abstract: OBJECTIVE
  To examine if physical activity (PA) variety was associated with moderate- to vigorous-intensity PA (MVPA) energy expenditure and body mass index (BMI) at 18 months during an obesity intervention.
  
  
  METHODS
  Participants with ≥ 10 minutes/week of MVPA at 6 months and complete PA data were included. Participants were classified into Variety (N = 30), ≥ 2 different activities/week, or Less Variety (N = 65), only 1 activity/week.
  
  
  RESULTS
  Weekly MVPA-related energy expenditure was higher for Variety than Less Variety (3674.7 ± 1934.6 kcal/week vs 2197.3 ± 1841.4 kcal/week, p < .05) at 18 months, with no difference in BMI.
  
  
  CONCLUSIONS
  Greater weekly PA variety during obesity treatment was related to greater 18-month MVPA energy expenditure.
