Hydration and Sports
Why is it so important to stay hydrated?
Whether you’re a serious athlete or a recreational exerciser, it’s important to make sure you get the right amount of water before, during, and after exercise. All athletes need to drink extra fluids to replace body water lost during exercise (e.g. sweat). When it's warm, your body perspires more to help you cool down. And depending on the temperature, humidity, and the nature of your activity, you might not even realize how much you are perspiring. Don't rely on thirst alone to tell you how much you need to drink. To keep those muscles working and avoid fatigue; it's extremely important to drink plenty of liquids before, during, and after the activity.
How much water should I drink while exercising?
There are no exact rules for how much water to drink while exercising because everyone is different. You need to consider factors including your sweat rate, the heat and humidity in your environment, and how long and hard you are exercising.
As a general rule, to maintain adequate hydration, drink fluids pre, during and post game, Drink about 250 -300 ml of fluid two hours before the activity. That helps make sure you are well-hydrated before you ever go outdoors. Then, during the activity, try to drink 150-200 ml every 15-20 minutes to keep your muscles well-hydrated. If you are planning an hour-long walk or gym workout, fill a water bottle with about 500 ml and take it with you.
What about sports drinks?
For most people, water is all that is needed to stay hydrated. However, if you will be exercising at a high intensity for longer than an hour, a sports drink may be helpful. The calories, potassium, and other nutrients in sports drinks can provide energy and electrolytes to help you perform for a longer period of time.
Choose a sports drink wisely. They are often high in calories from added sugar and may contain high levels of sodium. Also, check the serving size. One bottle may contain several servings. If you drink the entire bottle, you may need to double or triple the amounts given on the Nutrition Facts Label. Some sports drinks contain caffeine. If you use a sports drink that contains caffeine, be careful not to get too much caffeine in your diet.
What are the signs of dehydration?
