Should I Drink a Sports Drink?
Water is all that you need if high intensity exercise is <1 hour in length. However: keeping well hydrated is the central focus and sports drinks may help you to drink more because they taste good. If you will be doing exercise that elevates the heart rate continuously longer than 1 hour (eg. running, cycling etc.) a sports drink or an alternative source of carbohydrate is needed to keep your muscles fueled with energy.
Is coconut water a good choice?
Coconut water is extracted from young green coconuts and is very different from coconut milk which is extracted from mature coconuts.
1 cup of coconut water contains fiber, potassium, magnesium, vitamin C, sodium and carbohydrates.
Coconut water is marketed as a sports drink because it has approximately 46 calories, 9g of carbohydrate and 250 mg sodium (sports drinks have approximately 50 calories, 15g of carbohydrate and 110 mg of sodium). Endurance athletes may be getting their electrolytes drinking coconut water but may fall short in carbohydrates if they are falsely trading coconut water and sports drinks cup for cup since it is slightly lower.
