국문 초록 (Abstract)

20∼24歲의 男子 30名을 硏究對象으로 하여 選手詳과 非選手群으로 區分하였다. 運動負荷는 treadmill 傾斜 15%, 速度 5MPH에서 3分間 走破하게 한 後, 恢復期 1, 3, 5, 10, 20分에서 心搏動數, 血庄, 呼吸敎의 恢復樣相을 觀察하여 體力鍛鍊이 恢復期의 心肺機能에 미치는 影響을 分析하고, 나아가서 恢復期의 心肺反應이 體力을 評價하는 指標가 될 것인지를 알고자 試圖한 本 硏究結果를 要約하면 다음과 같다.
1. 安靜狀態의 心搏動數는 選手詳이 非選手詳에 比해서 有意하게 낮았으며, 血庄과 分時呼吸數는 別差異가 없었다.
2 . 運動負倚後 心搏動數의 恢復은 選手群이 非選手群보다 더 빨랐다. 恢復1分에 分時心搏動數는 選手群에서 117.2±5.21. 非選手群에서는 168.5±7.85이었고, 選手群에서는 運動後 安靜狀態의 150%까지 恢復되는데 所要되는 時間은 4分이었으며, 非選手群은 12.6分으로서 選手群이 약 3倍 程度 더 빨리 恢復되었다. 恢復20分에서는 選手群은 73.9±2.65, 非選手詳은 98 .5±4.47로 各各 恢復되었다.
3. 運動負倚後 收縮期血庄은 恢復1分에 選手群에서는 208.5±4.35mmHg, 非選手群에서는 172.9 ±6.29mmHg로서 選手群이 非選手群보다 높았다. 또 選手詳은 非選手群에 比해서 急速히 恢復되어 恢復5分에는 非選手群의 그것과 거의 같았다. 恢復20分에는 兩群 모두 安靜時血庄로 돌아왔다.
擴張期血庄은 選手群에서는 恢復3分까지 減少되는 傾向을 보이다가 그 이후 차츰 上昇하여 恢復20 分에는 82.8±2.03mmHg로서 安靜時의 그것보다 有意하게 增加하였으며, 非選手群에서는 恢復10分까지 減少되다가 그 이후 增加되었으나 安靜時에 比해 意義있는 差異가 없었다.
平均動脈庄은 恢復1分에 選手群에서는 115.2±2.64mmHg, 非選手群에서는 110.2±3.16 mmHg 로서 選手群이 非選手群보다 높았다. 選手群은 恢復5分까지 96.5±2.13mmHg로 急速히 恢復되다가 그 이후 20分까지는 거의 減少가 없으며, 非選手群은 恢復20分까지 繼續 減少되어 恢復20分에는 87.4±3.45mmHg로서 安靜時보다 낮았다.
脈庄은 恢復1分에 選手群에서는 136.7±4.24 mmHg, 非選手群에서는 94.1±7.65mmHg로서 選手詳이 非選手群보다 높았다. 選手群은 빠른 恢復을 하여 恢復5分이후 부터는 非選手群보다 낮았다. 恢復20分에는 兩群 모두 安靜時값보다 낮았으며, 특히 選手群은 38.7±1.59 mmHg로서 有意하게 낮았다.
4. 運動負荷後 呼吸數는 恢復1分에 選手群에서는 25.5±1.06, 非選手群에서는 34.7±2.33 이 었고, 兩詳 모두 1∼3分에 急速히 恢復되었다. 恢復20分에는 選手詳은 安靜狀態로 돌아온데 반해, 非選手群은 아직 安靜狀態로 恢復되지 못했다.
5. 本 硏究結果를 綜合하면 treadmill 運動負荷後 恢復期에 있어서 心搏動數, 血庄 및 呼吸數가 選手群에서는 急速히 恢復하는 반면, 非選手群에서는 緩慢히 恢復되었다. 특히 分時心搏動數가 選手群이 非選手群에 比해 安靜狀態에서 有意하게 낮았고, 運動後 恢復되는 樣相이 選手群에서는 安靜狀態의 150%까지 急速히 恢復되어 恢復時間이 非選手群에 比해 약 3倍나 빠른 것은 意義있는 結果이며, 恢復1分에 選手群이 非選手群에 比해서 心搏動數가 顯著히 낮았고, 이에 반해 收縮期血庄이 顯著히 높은 것은 또한 意義있는 結果로 思料된다.
또 擴張期血庄 乎均動脈庄 및 脈庄의 恢復樣相이 體力鍛鍊을 評價하는 指標가 될 것 으로 思料되어 앞으로 깊은 硏究가 要望된다.

다국어 초록 (Multilingual Abstract)

Thirty male subjects aged between 20-24 years were divided into athletic and non-athletic group. Running exercise was performed on a treadmill at 5 MPH, 15% grade for 3 min. The heart rate, blood pressure, and respiratory rate were measured at 1, 3, 5, 10, and 20 min after the termination of the exercise in an effort to analyze the physical training on the cardiopulmonary functions during the recovery period, and to find out if the cardiopulmonary responses during recovery period and be an index of physical fitness. The results are summarized as follows.
1. In resting state, heart rate was significantly lower in athletes that in non-athletes, while blood pressure and respiratory rate showed no significant differences between the two group.
2. The recovery of heart rate after the exercise was more rapid in athletes than in non-athletes. Heart rate at 1 min after the exercise was 117.2±5.21 in athletes and 168.5±7.85 in non-athletes. The recovery of heart rate to 150% of the resting level required 4 min in athletes and 12.6 nin in non-athletes, indicating that the recovery was 3 times faster in athletes that in non-athletes. Heart rate at 20 min was 73.9±2.65 in athletes and 98.5±4.47 in non=athletes.
3. Systolic pressure at 1 min after the exercise was 208.5 ± 4.35 mmHg in athletes comparing with 172.9 ± 6.29 mmHg in non-athletes. The recovery was more rapid in athletes, so that the systolic pressure became similar in both groups at 5 min. The resting level was restored in 20 min in both groups.
Diastolic pressure in athletes showed a tendency to decrease until 3 min after the exercise then increased followed by a gradual increase and reached 82.8±2.03 mmHg at 20 min after the exercise, which is significantly higher than the resting level. In non-athletes, the diastolic pressure decreased until 10 min after the exercise and then increased, but showed no significant difference from the resting level.
The mean arterial pressure at 1 min after the exercise was 115.2 ± 2.64 mmHg in athletes and 110.2 ± 3.16 mmHg in non-athletes. In athletes it decreased rapidly to 96.2 ± 2.13 mmHg at 5 min after the exercise and then showed little decrease until 20 min. In nonathletes it decreased steadily to 87.4 ± 3.45 mmHg at 20 min which is lower than the resting level.
Pulse pressurc at 1 min after the exercise was 136.7 ± 4.24 mmHg in athletes and 94.1 ± 7.65 mmHg in non-athletes. In athletes it showed rapid recovery reaching lower level than that of non-athletes after 5 min. At 20 min after the exercise, the pulse pressure was lower than the resting level in noth groups, especially significantly in athletes (38.7 ± 4.59 mmHg)
4. Respiratory rate at 1 min after the exercise was 25.5 ± 1.06 in athletes and 34.7 ± 2.33 in non-athletes, and showed rapid recovery from 1 to 3 min after the exercise in both group. At 20 min after the exercise, the resting, level was restored in athletes but not in non athletes.
5. In summary, heart rate, blood pressure and respiratory rate during the recovery period after treadmill exercise showed rapid recovery in athletes, while slow recovery was observed in non-athletes. Especially significant is the result that the heart rate of the resting state was significantly lower in athletes than in non-athletes, and that the recovery was 3 times more rapid in athletes than in non-athletes. The result indicating that the heart rate at 1 min after the exercise was significantly lower and the systolic pressure was significantly higher in athletes than in non-athletes is also considered highly significant. The recovery pattern of the diastolic pressure, the -lean arterial pressure and the pulse pressure can be considered to be a useful index in evaluating the effectiveness of the physical training. Further studies on the subject are deemed essential.
