Lecture - sports (physical activity) nutrition - part ii. What are sports drinks: liquids that provide water and nutrients to support physical exercise, carbohydrate-electrolyte solutions. Carbohydrate-electrolyte solutions: simple carbohydrate (glucose, fructose, disaccharides, electrolytes: na+, k+, cl- Replace what is lost: carbohydrates depends on exercise intensity/ duration, na+ preventing hyponatremia, h2o maintain cooling mechanism. Gatorade (6% concentration: 50 kcal, 110 mg na (5%), 30 mg k (1%), 14 g cho (6%, sucrose, glucose, fructose. Powerade (8% concentration: 50 kcal, 100 mg na (4%), 25 mg k (1%), 14 g cho (6%, high fructose corn syrup. 116: 8 endurance-trained men (22 yrs, 72 kg, vo2peak = 66. 9 ml/kg/min), cycling, 69% vo2peak to fatigue, 250 ml. Results: exercise time: 199 + 21 min (cho) vs. 152 + 9 min (con), muscle imp greater in con than cho, 7 endurance-trained cyclists, 2 hrs. cycling, 63% Results: dehydration increased rectal temperature, better na+ balance with.
