FLUID INTAKE STRATEGIES FOR OPTIMAL HYDRATION AND PERFORMANCE: PLANNED DRINKING VS. DRINKING TO THIRST

KEY POINTS In humans, thirst tends to be alleviated before complete rehydration is achieved. When sweating rates are high and ad libitum fluid consumption is not sufficient to replace sweat losses, a cumulative loss in body water results. Body mass losses of 2% or greater take time to accumulate. Dehydration of > 2% body mass and greater is associated with impaired thermoregulatory function, elevated cardiovascular strain, and in many conditions impaired aerobic exercise performance (e.g., warmer, longer, more intense). Circumstances where planned drinking is optimal include: longer duration activities > 90 min, particularly in the heat; higher intensity exercise with high sweat rates; exercise where performance is a concern; when carbohydrate intake of 1 g/min is desired. Circumstances where drink to thirst may be sufficient include: short duration exercise < 60 to 90 min; exercise in cooler conditions; lower intensity exercise. NEVER drink so much t...

How well do different drinks really hydrate you?

How Well do Different Drinks Really Hydrate You? JUNE 20, 2016 BY ANDY BLOW How well different types of drinks are retained in the body is a question I get a fair bit, and it’s of some practical use. In theory, the longer you can keep the fluids you drink onboard the greater the chance they have of being absorbed into the bloodstream and used effectively in the body. There’s also the side benefit of less interruptions for bathroom breaks, which is useful during training and competing. Whilst you’re inevitably going to pee out a good proportion of all the liquid that passes your lips, all drinks are definitely not treated equally by the body in this particular regard. Substances like caffeine and alcohol have the potential to increase urine output and reduce fluid retention, whilst calories and electrolytes in drinks can slow the emptying rate of the stomach and positively influence the absorption of fluid from the gut into the bloodstream. Most of the f...
