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

Appl Physiol Nutr Metab. 2018 Apr;43(4):423-426. doi: 10.1139/apnm-2017-0675. Epub 2018 Jan 9.


We assessed the effect of metaboreceptor activation on whole-body evaporative heat loss (WB-EHL) in 12 men (aged 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.
