Clothing impact on post-exercise comfort: skin-clothing physiology in transient environment.

Sportswear manufactured from hygroscopic fibres can absorb moisture during activity or intermittent exercise and may change the thermal management of clothing. This change in the thermal behaviour of the fabric can lead to buffer the post-exercise chill. During activity in a moderately cold environment clothing made of 100% wool fibre helps wearers to slow down evaporative and conductive cooling, which can provide more thermal and comfort sensation compared to 100% cotton, 100% viscose, and 100% polyester. Twelve males performed cycling in a controlled climate chamber of temperature: 15 ± 0.5 °C, and relative humidity (RH):50 ± 5% followed by a drying phase in a windy environment by wearing full-sleeve t-shirts. Wool shirt was observed to hold a greater torso skin temperature (p < 0.05) than the other fibre types. Participants were asked a range of comfort-related questions at varying intervals. The temperature sensation was found (p < 0.05) significant for wool clothing. Moreover, participants rated wool shirt significantly (p < 0.05) as more comfortable during the post-exercise phase.
