Purpose : The purpose of this study was to identify the change of forced vital capacity on the ground and in the water in the normal adults.
Method: Twenty healthy university students(men 10, women 10) participated in this study and they were measured forced vital capacity(FVC), forced expiratory volume at one second (FEV1), a ratio for forced expiratory volume at one second on forced vital capacity(FEV1/FEV), forced expiratory flow of 25%~75% range(FEF25~75%), FEF25%, FEF50%, and peak expiratory flow(PEF) using the vital capacity device on the ground and in the water pool. The statistics was used paired t-test between the values on the ground and in the water.
Results : The values of FVC and FEV1 on the ground were significantly higher than in the water(p<.05). There were no difference in the parameters of FEV1/FEV, FEF25~75%, FEF25%, FEF50%, and PEF.
Conclusion : The FVC and FEV1 in the water can be affect for increasing pressure on the chest wall and abdomen as the hydrostatic pressure of the part in the water physical features. This study recommend that the physical therapist should be considered a depth of water in water pool depending on the function of lung and expiratory muscles when they treat patients for aquatic therapeutic exercise.
