The purpose of this study is to investigate the cardiorespiratory responses during submaximal work on the different body surface pressure areas by wearing a pressure suit which can apply pressures on the individual regions of the human body surface. The oxygen intake, ventilation, respiratory frequency, tidal volume and the heart rate were measured during bicycle ergometer exercise. The work loads corresponded to 30% and 60% of Vo2max. The pressures applied were 10mmHg and 40mmHg. The pressure time before work were 3min. and 40min.. The pressure time before work has no effect on those physiological values. The heart rate, ventilation and oxygen intake were increased by the pressure during work with the load of 60% Vo2max. It was supposed that the increase of the oxygen intake might resulted in an increase of the energy expenditure of respiratory muscles.
