Time for the American College of Sports Medicine to acknowledge that humans, like all other earthly creatures, do not need to be told how much to drink during exercise

The point, as made in our response to Dr Murray, is that when the GSSI began to advertise the ACSM guidelines, it conveniently forgot to include some of the qualifications included in those guidelines and that might have reduced the extent to which athletes in the USA began to overdrink in the 1990s. [...]the message that the sporting public received was not that athletes should "consume the maximal amount of fluids during exercise that can be tolerated ... or up to a rate equal to that lost in sweat", but that they should simply drink "as much as tolerable". [...]Dr Roberts argues that to "replace only your sweat losses remains the best advice today".
