운동자세 및 의복압이 최대의 산소섭취량(VO₂Pmax)에 미치는 영향

This study focuses on the influence of body pressure for posture and clothing pressure on physiological responses of the human body from the viewpoint of clothing physiology. Physiological responses for different exercise postures and different levels of clothing pressure were examined. Six untrained female subjects performed leg exercises, using a bicycle ergometer in the supine and sitting postures. Clothing used in the experiment consisted of two kinds of sportswear -non-pressure suits and pressure suits-both of which were made in the same shape of short sleeves and short pants and were made of the same material of 90% nylon/10% polyurethane. Environmental conditions were at 30±1℃ air temperature, 50±10% relative humidity and 0.2m/sec air velocity. Clothing pressure on the 10 sites of the human body surface and maximal of oxygen intake(V˙O2Pmax) were measured. As a result, body pressure for posture was significantly higher(45 ~55gf/cm3) than the clothing pressure(3~ 25gf/cm2). V˙O2Pmax during exercise was affected both by the posture and clothing pressure. V˙O2Pmax in the sitting posture was 9∼20% higher than that for the supine posture, and V˙O2Pmax in the pressure suits was 2∼12% higher than that in the non-pressure suits.
