Conclusion

It best to drink isotonic drinks but if you can get hold or don't have any then water is the next best thing. During exercise: Hydrate Drink 1/4 of your drinks bottle (187ml) every 15-20 minutes during a workout After exercise: Rehydrate for an accurate fluid loss calculation weigh yourself before and after a workout. For each pound of body weight lost drink 2 cups (16 oz.) of water. If you don't have access to a scale, drink until your urine is clear. Clear urine is a good indication of adequate hydration. Rehydration - an important element of training and preparation towards competitions. Athletes need to drink during competitions and training sessions. Cold water (10?) is absorbed more rapidly than hot one. Dissolved gases slow down absorbtion (Cola, carbonated drinks are not useful), as well as any added suger or protein for instance. Thirst is not a good indicator of fluid loss - Drink before you're thirsty! * Avoid caffeine and alcohol, they increase fluid losses * Drink fluids at a cool temperature. * Unless you are an ultra-endurance athlete participating in events lasting over 8 hours, electrolyte (sodium, potassium, and chloride) losses from exercise are easily overcome by typical intakes from the regular diet. Therefore, salt tablets and other electrolyte replacements are not recommended. Sports drinks that content 7-10% of sugar are the best drinks to drink after training or competitions, as they are absorbed faster. Appropriate Dehydration and Recovery Strategies. Treatment: Oral rehydration may be sufficient for mild dehydration. Mild dehydration is safe to self-treat for all ages, as long as it doesn't worsen. Ways to do this is to drink, slightly sparkling water. This will help you recover from dehydration quicker than drinking water. If you're severely dehydrated, you must get to a hospital right away. Intravenous fluids and hospitalization may be necessary for moderate to severe dehydration. The health care provider must also determine and treat the cause of the dehydration. To treat dehydration, you must first address the cause: Fever, Vomiting, Diarrhoea, and Heat Exhaustion are the most common reasons for extreme dehydration. ...read more.
