There has always been a controversy between whether sports drinks are good for you or bad for you. Well here is your answer: it depends. Drinking it while you sit on the couch watching tv, not good for you. Drinking it during or after exercising, that's good for you! The only time you should drink them is when you need to replenish your electrolytes, otherwise it's just unnecessary sugar for your body. It would be the equivalent to drinking a soda.
There are many different types of sports drinks such as Gatorade, PowerAde, All Sport, and I consider Propel a sports drink too. It is not bad if you drink one after just a simple run, but these sports drinks should be used only when you are still exercising, and you feel physically drained. You feel this way because when you sweat, you lose salts, or electrolytes, and your body needs them to run properly. Without the salts, your muscles could cramp up, and trust me, that is the worst pain of ever (I'm exaggerating)!
If I have a preference of these sports drinks, my favorite is Gatorade, the yellow one to be exact. My dad likes to surprise me with the giant bottles of Gatorade, and don't get me wrong I get really excited, but they usually just sit in my refrigerator until my next activity. I can say from personal experience, Gatorade actually replenishes your energy! I was playing in the 5th set of the regional semi-finals for Volleyball (this is the start of the state tournament, meaning you lose and your out!), and we had played almost every single point that could be played. The scores were 22-25, 21-25, 26-24, and 25-23 and I was absolutely exhausted. I could have probably laid down in the middle of the court and slept! So what did I do? I grabbed my handy dandy Gatorade and chugged that puppy down. That 5th set, I had more energy than the first, may that be accredited to the adrenaline of being in such a close match or not, and we won and advanced to the regional final! It was great.
So yes, Gatorade is good for you in those tough workouts and long games, but I wouldn't recommend it for your everyday workout. It is very sugary, and sugar leads to fat.
