PDF Thermal Physiological Studies on Comfort and Thermal Sensations and Physiological Responses during Exercise

【Supercategory:7. DESCENTE SPORTS SCIENCE Subcategory:7.12 Vol.12

 In the present work, we made some experiments in an attempt to elucidate the significance of relationships between physiological res-ponses and comfort and thermal sensations during exercise.
 Changes in preferred comfortable temperature (Tpref) were examined during exercise in 10 male subjects. The rate of change in Tpref was highly related to body core temperature. From these results, it is conceivable that the increase of core temperature during exercise is not due to change in the set point for thermoregulation.
 In order to clarify the influence of clothing on comfort and thermal sensations during and after exercise, the survey with questionaire was made in 42 male students and 49 female students in a physical education class. Vo₂ was estimated by measuring changes in heart rate after exercise.
 The results were compared between two groups one wearing of clothes with long sleeves and the other with half sleeves. More students with long-sleeved clothes felt hot and uncomfortable than students with half-sleeves. Vo₂ did not differ between the two groups.
 It was found that sensations had better correlations with the clothing microclimate. Discomfort during exercise does not seem to be related to temperature regulation disorder. The relationship between core temperature and skin temperature influences comfort sensation during exercise.
