KELLAM, Stephanie et al. Effect of exercise dosages on adiposity indices in overweight girls. Salud pública Méx [online]. 2013, vol.55, suppl.3, pp.415-421. ISSN 0036-3634.

Objective. The primary purpose of this study was to determine the impact of two exercise dosages on reducing adiposity in minority girls. Materials and methods. Sixty-two overweight Hispanic and African-American girls participated in one of two intense summer interventions in Houston, TX: Intervention A (exposure to about 40 hours physical activities) or Intervention B (exposure to 60 hours of physical activities). Adiposity indices (percent body fat, waist circumference, body mass index) were taken pre- and post-intervention. Results. Intervention B had a significantly greater decrease in adiposity indicators (p= 0.006) when compared to Intervention A. Waist circumference displayed the most significant decrease (p = 0.001). Both interventions significantly increased daily minutes of moderate-to-vigorous physical activity (p= 0.020). Conclusions. Intense physical activity interventions may effectively reduce abdominal fat in minority girls.
