| Abstract | 「要旨」心筋梗塞(MI)回復期の運動処方にはanaerobic threshold(AT)レベルが広く用いられるようになった. しかし実際のATレベル運動中の呼吸循環動態の変化については十分な検討がなされていない. そこで本研究では, ATレベル単一運動中の呼吸循環動態の変化につき検討した. 急性期リハビリテーションを完了した発症後1ヶ月の患者10名(MI群 : 平均57.3±10.9歳), 健常若年男性10名(健常群 : 平均24.8±3.6歳)に対しトレッドミル心肺運動負荷試験(ramp法)を行い, AT, 最高酸素摂取量(peak VO2)を求めた. 別の日に6分間のwarm-upの後, 運動時間が30分になるようにそれぞれのATVO2, レベルの単一負荷を24分間施行し, 健常群とMI群の比較を行った. 1)AT, peak VO2, AT時心拍数はいずれも健常群で有意な高値を示した. 2)ATレベル単一負荷時のVO2, ガス交換比, 酸素脈, 2重積には有意な変化を認めなかった. 3)単一負荷開始10分後の心拍数はramp負荷で求めたAT時心拍数に近似したが, 24分後の心拍数は両群共に有意に増加した. |

| Abstract | Recently, it has been recognized that anaerobic threshold (AT) could be an useful index for exercise prescription in patients with myocardial infarction (MI). Although there are numerous descriptions on effects of AT-level exercise training in patients with MI, reports documenting the effects of single-level exercise at the AT-level on cardiopulmonary function have been few. Then, the present study was conducted with the purpose of investigating the effects of AT-level exercise upon oxygen uptake (VO2) kinetics and cardiopulmonary function in healthy volunteers and in patients with MI. The subjects consisted of 10 healthy male volunteers (mean age 24.8±3.6 years) and 10 consecutive patients who had completed the routine 4-week cardiac rehabilitation program for the acute phase of MI (all were males ; mean age 57.3±10.9 years). Two kinds of treadmill exercise testing was performed. At first, symptom-limited exercise testing was performed by using a ramp treadmill protocol. After 3-min rest on the treadmill, exercise was started with 3-min warm-up (speed : 1.0mile/h, grade : 0%) followed by an increase in load every 1 min. AT and peak VO2 was determined in this study. Secondly, single-level exercise testing at AT level was performed on the different day for measuring VO2, heart rate, pressure rate product, oxygen pulse, gas exchange ratio, respiratory rate, tidal volume and the ventiratory equivalent for O2 (VE/VO2). |
