Title Age-related thermal strain in men while wearing radiation protective clothing during short-term exercise in the heat
Bibliographic information 2004, Vol.10, No.4, p.361-367. Illus. 26 ref.
Abstract The aim of this study was to compare heat strain among different age groups of men wearing protective clothing during short-term physical work. Eight young (20-29 years), six middle-aged (41-55 years) and eight older (58-65 years) men exercised for 30 min on a cycle ergometer in two hot environments with a similar WBGT, once with minimal clothing without infrared radiation (E1), and once while wearing aluminized protective clothing under infrared radiation (E2). All subjects had sedentary jobs, but only the older subjects were physically active in their leisure-time. Body temperatures, heart rate, sweat rate and subjective feelings were determined during the tests. Higher thermal strain was observed in E2 than in E1. No age-related differences in thermal strain were observed in either experiment indicating that active older men can tolerate short work periods with protective clothing in the heat as well as younger sedentary men.
