장기간의 유산소운동이 폐확산 능력에 미치는 영향 = Effect of Long Term Aerobic Exercise on diffusing Capacity of Lungs

다국어 초록 (Multilingual Abstract)

The purpose of this study was to investigate long term aerobic training effect on diffusing capacity of lungs in female tennis players. 14 female tennis players belonged to professional tennis teams and 9 controls were participated in this experiment.
Mean diffusing capacity of lungs for carbon monoxide(DLco) of tennis player were 30.2ml/min/mmHg which was significantly higher than that of controls.
Alveolar ventilation of tennis players was 5.95 liter and that of controls was 4.52 liter, so experimental group was significantly different(P < 0.001) from controls.
The ratio of DLco/Va was revealed that measured value was higher than preadicted value in tennis players, bur the measured value of controls was lower than predicted value. the ratio of exprimental group was showed 108% and that of controls was showed 94.5%.
Krogh s constant of tennis players was 4.35 min, which was 87.7% of their predicted value and that of control group was 3.7 min, which was 74% in their predicted value. Both tennis players and controls of measured values were revealed. significantly lower than their predicted values.
Although diffusion was made by partial pressures of gas between alveolar air and blood supply, diffusing capacity of lungs were influenced through long term aerobic exercise.
