본 연구는 운동전 흡연과 단기간 흡연 중단이 심폐기능에 미치는 영향을 알아보기 위해 동일 피험자를 운동전 흡연, 3일 금연, 5일 금연을 시킨 후 측정하였다. 평소 흡연을 하고 있는 17세 남자 6명을 대상으로 안정시, 운동중, 최대운동 직후 그리고 운동후 회복시 동일시간대별 심폐기능을 조사하였다. 측정된 자료는 반복측정에 의한 일원변량분석을 통하여 분석한 결과 다음과 같은 결론을 얻었다. 1. 처치에 따른 동일시간대별 심박수는 안정시, 운동 3분, 운동 9분, 최대운동에서 차이가 있었고, 운동 6분, 회복 3분, 회복 6분에서는 차이가 없었다. 2. 처치에 따른 동일시간대별 체중당 산소섭취량은 운동 6분, 운동 9분, 회복 3분에서 차이가 있었고, 안정시, 운동 3분, 최대운동, 회복 6분에서는 차이가 없었다. 3. 처치에 따른 동일시간대별 환기량은 운동 9분과 최대운동에서 차이가 있었고, 안정시, 운동 3분, 운동 6분, 회복 3분, 회복 6분에서는 차이가 없었다. 4. 처치에 따른 동일시간대별 수축기혈압은 안정시, 운동 3분, 운동 6분, 운동 9분, 최대운동, 회복 3분, 회복 6분 모두 차이가 없었다. 5. 처치에 따른 운동지속시간은 차이가 있었다.

The purpose of this study was to investigate the effect of a before-exercise smoking and a short-term prohibition of smoking on the cardiopulmonary functions by allowing the subjects to smoke before exercising and prohibiting the same subjects from smoking for three days and five days for measurement of the cardiopulmonary functions. The measurement was taken among the same time for six males aged 17 who were usual smokers while they were at rest, in the midst of exercise, right after the maximum exercise and during recovery from exercise. The measured variables was completed through the one-way ANOVA by repeated-measures as follows; 1. On each research into the heart rate among the same time during rest, three-minute exercise, nine-minute exercise and maximum exercise, there were differences and during six-minute excercise, three-minute recovery, six-minute recovery there was no difference. 2. On each research into the VO₂ /㎏ among the same time excercise, nine-minute excercise and three-minute, there were differences and during rest, three minute excercise, maximum excercise, six-minute excercise and six-minute recovery, there was no difference. 3. On each research into the VE(ℓ/min) among the same time nine-minute excercise and maximum excercise, there were differences and during rest, three-minute excercise, six-minute excercise, three-minute recovery and six-minute recovery, there was no difference. 4. On each research into the Systolic Blood Pressure among the same time during rest, three-minute excercise, six-minute excercise, nine-minute maximum excercise, three-minute recovery and six-minute, recovery there were differences. 5. On each research into exercise duration among the same time there were differences.
