| Abstract: | The effect of clothing openings on thermoregulatory responses of wearers
during a treadmill exercise in controlled laboratory conditions has been studied. Nine short sleeved T-shirts
with varying design of clothing openings at neck
and hem have
been designed, and the test is performed on six males, considering 10min of standing rest, 30min of running at 55% of VO2max
followed by 10min of rest. Heart rate, rectal temperature (Tre), skin temperatures (Tsk), clothing microclimate
temperature (Tcl) and relative humidity (RHcl) have been studied and the subjective ratings on thermal,
sweating and comfort sensations are collected. The results show significant differences in mean values of skin Tsk, Tcl and RHcl
among
the clothing
with different sizes of neck openings. There are no significant differences
between clothing with moderate and loose hem opening. Heat storage during
exercise and recovery periods shows significant relations with the ventilation area of
clothing neck opening. It appears that the neck opening plays a more significant role to
improve heat transfer during exercise than the hem opening. Hence, varying design of clothing
openings could affect thermophysiological comfort of wearers; the T-shirt with loose neck
opening and moderate hem opening is the best one in releasing heat from the body. |
