A Comparative thermophysiological study in sport bras for running

Abstract

Comfort in clothing is essential for user's performance and is considered as a quality factor when choosing a particular piece of garment. Sportswear's need include comfort and functionality, meaning that the thermo-physiological properties are of extreme importance. The aim of this work consists in comparing six different models of sports bra used specifically for running, taking into consideration the aspects of the thermo-physiological properties, air permeability, moisture behaviour, and friction. This paper is part of an ongoing research aiming to establish a comprehension about function and comfort characteristics for sport bras and propose a new bra with improved characteristics both in ergonomics design as well as in comfort performance. The thermal characterization of different regions on each bra were tested using Alambeta apparatus, Textest FX 3300 for air permeability and Frictorq for friction. Evaporation tests were also carried out in different regions on each bra at 37°C corresponding to internal temperature of the human body. The results show that raw material, structures and construction can have influence in the properties studied.
