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.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
