Comment on “Drinking Strategies: Planned Drinking Versus Drinking to Thirst”

Letter to the Editor

Dear Editor,

In the article by Kenefick [1], the author stressed that a sufficient drinking strategy during exercise will provide for “maintenance of fluid balance within ± 2% body mass”. Subsequently, in his response [2] to a letter to the editor on this article [3], Kenefick further clarifies his beliefs by stating “The recommendation made in my review is to prevent dehydration and over-drinking within a fluctuation of ± 2% body mass and to never consume so much fluid that > 2% body weight is gained. There is no evidence whatsoever that this recommendation would lead to harm”. To be fair, by considering the full context of this statement, he offers no qualifiers that would suggest he is limiting such a statement to particular exercise durations or other conditions. Thus, at the risk of appearing to be caviling, this quote cannot go without comment since considering it to be accurate could indeed lead to harm.

It has long been recognized that exercise-associated hyponatremia (EAH) may...
