Males (N = 7) exercised in a thermoneutral environment (23 degrees Celsius, 42% relative humidity). Three types of clothes were worn on the torso on separate occasions; bare-chested (BC), cotton shirt (CS), and a nylon shirt (NS).
There were considerable differences in indices in two-condition comparisons. Generally, it was found that the cotton shirt impacted thermoregulatory capacity more negatively than the other two conditions.
Implication. Cotton shirts cause more negative effects on exercise responses than do nylon shirts or a bare-chested condition.
