Tattoos do not affect exercise-induced localised sweat rate or sodium concentration

Skin tattoos have been shown to reduce localised sweat rate and increase sweat sodium concentration ([Na+]) when sweating is artificially stimulated. This study investigated whether similar responses are observed with exercise-induced sweating.Unblinded, within-participant control, single trial.Twenty-two healthy individuals (25.1±4.8 y (Mean±SD), 14 males) with a unilateral tattoo ≥11.4cm2 in size, ≥2 months in age, and shaded ≥50% participated...
