The key to good hydration is drinking a lot of water before, during and after any workout or activity. Water is essential for proper bodily function. Sports drinks aren’t only way to consume electrolytes. Eating a normal diet will provide body with more than enough electrolytes needed for exercising and physical activity.

Energy drinks can be helpful to athletes who are exercising at a high intensity for 90 minutes or more. Fluids supplying 60 to 100 calories per 8 ounces helps to supply needed calories required for continuous performance. It's really not necessary to replace losses of sodium, potassium and other electrolytes during exercise since you're unlikely to deplete your body's stores of these minerals during normal training. If, however, you find yourself exercising in extreme conditions over 5 or 6 hours (an Ironman or ultramarathon, for example) you will need to add a complex energy drink with electrolytes.

Does average consumer derive any real benefit from sports drinks? It's a marketing gimmick, pure and simple. Most health experts agree that sports drinks have electrolytes and sodium that are beneficial to professional athletes and marathoners, but have little value to average user. There's a certain appeal in drinking what Olympic athletes drink, but it should be just water if you're doing 10 minutes on a treadmill. And because many enhanced waters contain only small amounts of essential nutrients, consumers should look elsewhere for nutrition. That's what we have food for!
