目的：旨在探討沒有運動習慣大專生在急性負荷下對其體循環與新陳代謝反應之影響。方法：受試者為9名沒有運動習慣大專生，平均年齡21±1.2歲，身高與體重分別為167±8.0 cm、63±14.4 kg。測試以划船測功儀進行，負荷型態為3次10槳（3x10），每次間歇90s，每人必須以個人最大速度進行。結果：血液乳酸在第一組（1x）為2.7±0.6 mmol/l，第三組（3x）乳酸堆積上昇4.5±1.0 mmol/l兩次差異+1.8 mmol/l（p＜0.00）。最大乳酸堆積濃度於恢復期第七分鐘呈現，平均值為5.3±2.2 mmol/l。心跳率在1x負荷呈現148±13 min^(-1),3x呈現154±13，與1x平均值差異+6 min^(-1)（p＞0.05）。結論：結果分析顯示在急性最大負荷，乳酸與心跳率皆呈現於無氧症狀反應。此現象顯示沒有運動習慣者，不適合從事高負荷的身體活動。養成平時運動習慣，才能維持正常的生理機制。

Purpose: To investigate the impact of systemic circulation and metabolic response to the students without exercise habit on the acute load. Method: The subjects were 9 college students without exercise habit. (age: 21±1.2 years old, height: 167±8.0 cm, weight: 63±14.4 kg). The test was conducted maximum load on rowing ergometer. (3sets*10 SPM, rest 90s between sets). Result: The blood lactate concentration of first set (1x) was 2.7±0.6 mmol/l, third set (3x) rose to 4.5±1.0 mmol/l, variation was +1.8 mmol/l (p=0.00). The maximal level of lactate was observed at the seventh minutes after exercise, average value was 5.3±2.2 mmol/l. Heart rate was 148±13 min-1 at 1x, 154±13 min^(-1) at 3x, variation was +6 min^(-1) (p＞0.05). Conclusion: At the acute load of maximal exercise, the lactate level and heart rate were presented the symptoms of anaerobic. This phenomenon showed that people without exercise habit are not suitable to high intensity activity, instead, to keep usually exercising in a habit can maintain normal physiological mechanism.
