Abstract

This study examines the rate at which the body metabolizes blood sugar after physical activity when consuming brown sugar compared to white sugar. The identified problem is the lack of empirical data on whether the small percentage of digestive inhibitors in brown sugar affects glucose metabolism during the severe metabolic stress response of physical activity. Studies on similar topics show that polyphenols in brown sugar slow carbohydrate metabolism at rest; however, severe physical activity causes the body to create a vacuum in the muscles through GLUT4 translocation. This study attempts to fill the gap in the literature on whether these two mechanisms affect each other, in order to simplify solutions for athletes, those managing diseases like Type 2 Diabetes, and diet-conscious individuals seeking better blood sugar control before and after exercise. Using a randomized, counterbalanced crossover design, 36 high school athletes completed a 15-minute anaerobic depletion protocol before consuming 50 grams of carbohydrates as either white or brown sugar. Blood glucose was measured via finger-prick testing every 15 minutes over one hour. Results showed no significant difference in clearance rates between the sugars, accepting the null hypothesis. Both sugars produced the same spike at the 30-minute mark, followed by the same rate of decline over the remaining 60 minutes. This indicates that the muscles' high fuel demand overrides the slowing effects of trace polyphenols in molasses. It was concluded that under acute metabolic stress, the chemical differences between brown and white sugar are insignificant; for acute recovery, a carbohydrate is a carbohydrate. Further study will use Continuous Glucose Monitors (CGMs) to assess whether these minerals benefit athletes over a full 24-hour cycle.
