Postexercise whole-body sweating increases during muscle metaboreceptor activation in young men

We assessed the effect of metaboreceptor activation on whole-body evaporative heat loss (WB-EHL) in twelve men (24±4 years) in the early-to-late-stages of a 60-min exercise recovery in the heat. Metaboreceptor activation induced by 1-min isometric-handgrip (IHG) exercise followed by 5-min forearm ischemia to trap metabolites increased WB-EHL by 25-31% and 26-34% during the ischemic period relative to IHG-Only and Control (natural recovery only) respectively throughout recovery. We show that metaboreceptor activation enhances WB-EHL in recovery.
