Skin Tattoos Do Not Affect Exercise-induced Sweat Rate Or Sodium Concentration.

PURPOSE: Skin tattoos have been shown to reduce sweat rate and increase sweat sodium concentration when sweating is artificially stimulated. This study investigated whether similar responses are observed with exercise-induced sweating. METHODS: Twenty-two healthy individuals (25.1±4.8 y (Mean±SD), 14 males) with a unilateral tattoo ≥11.4 cm2 in size, >2 months in age, and shaded ≥50% participated in this investigation. Participants undertook 20...
