The purpose of this study is to investigate and measure the process of metabolic and physiological recovery following hairwashing on reclining subjects. The investigation involved 16 healthy female students between the ages of 19-22 each of whom participated in the investigation once. The following results were obtained: 1) The process of recovery after hairwashing, which took 7.4 minutes, was 4 minutes approximately, a comparatively speedy recovery. There was no rebound effect. 2) The heart recovery rate was quicker than the oxygen recovery rate. Therefore the heart rate cannot be used as an index of recovery time. 3) After 12 minutes, total expiration volume, the percentage of expired CO_2 and inspired O_2, the volume of expired CO_2, calorie consumption and respiration quotient fell below the rest level. This establishes the point of recovery at 12 minutes, on the average. However, in individual cases, we believe it is better to regard a range within ±10% of the rest level as the suitable point of recovery. This method seems to be an improvement on previous methods. |
