Título Metabolic effects of facial cooling in exercise
Información bibliográfica Jan. 1983, Vol.54, No.1, p.22-26. Illus. 23 ref.
Resumen Exercise on a bicycle ergometer at 50rpm was performed in 5 subjects for 1h at 60% maximal heart rate, with and without a cold wind (10°C, 6.5m/sec). Facial cooling resulted in significantly greater fat utilisation. After 5min the respiratory exchange ratio, blood lactate concentration, oxygen consumption and estimated myocardial oxygen consumption were higher with facial cooling. The metabolic changes occurring with facial cooling are related to general thermoregulatory response. The stress of exercise is greater with facial cooling (corresponding to a situation in which workers in a cold environment wear protective clothing and have their faces exposed to a cold wind).
