Right Time To Rehydrate [Workout Tips]

You know how it feels to exercise in 90-degree heat if you skimped on water beforehand. Now, new research has quantified dehydration’s actual physical effect on performance and led to a new way to think about watering up pre-workout.

According to the Journal of Strength and Conditioning Research, for every 1% body mass you lose through sweat, your heart rate ticks up three beats a minute, which means it has to work harder. Not good. On the flip side, “staying hydrated helps hold in more water, so your heart has to work less to pump the blood to muscles,” says study author William Adams, M.S., A.T.C., so “keeping your heart rate low allows you to exercise with a higher intensity.”

Studies have found that athletes who lose as little as two percent of their body weight through sweating have a drop in blood volume, which causes the heart to work harder to circulate blood. A drop in blood volume may also lead to muscle cramps, dizziness, fatigue and even heat stroke
