A methodology of selecting a suitable garment for sports use

Abstract

Purpose

Choosing the adequate garment for sports practice in adverse weather conditions, either cold or hot, is an aspect of great influence on activity performance. The purpose of this paper is to describe how the Institute of Biomechanics of Valencia has developed a methodology which allows assessing the fit of the garment to the real situation of use by evaluating its influence in the thermoregulatory response of the human body.

Design/methodology/approach

Under controlled environmental conditions and at fixed activity levels, two shirts are tested in the laboratory. Eight subjects performed a test which consisted of six phases of different activity level in two conditions (25°C/50 percent RH and 10°C/60 percent RH). Throughout the test, physiological parameters of the thermal response as well as work load indicators are registered. Skin temperature at three different locations (chest, arm, and thigh), microclimate variables in some areas of subject‐garment interface (in armpit and upper back) and heart rate are measured continuously. Six samples of sweat are also collected regularly from dorsal region during the test to estimate the sweating rate and the loss of salts. Weight loss is also checked before and after performing the test to estimate the dehydration level. Subjects will be asked during the test about humidity and temperature perception on the body as a whole or by different zones. The results allowed measuring a significant influence of the shirt in skin temperature. Therefore, the methodology developed for studying of the user‐product interaction through the assessment of the thermophysiological response and the subjective perception allows recommending the comfort ranges for each piece of garment as well as indicating those work load and environmental conditions for which the influence of garment on user's performance is optimal.

Findings

The user‐product interaction through the assessment of the thermophysiological response and the subjective perception allows recommending the comfort ranges for each piece of garment as well as indicating those work load and environmental conditions for which the influence of garment on user's performance is optimal.

Originality/value

Choosing a suitable garment for sports practice in adverse weather conditions, either cold or hot, is an aspect of great influence on activity performance and this paper presents new results.
