「Adjustments of cardiac function during prolonged exercise relative to lactate threshold」

Alterations in cardiac function during prolonged submaximal exercise relative to lactate threshold (LT) were evaluated on 7 normal healthy males. Although the heart rate and oxygen uptake increased during exercise, the ability of maintaining heart muscle contractility remained almost unchanged. （乳酸閾値強度での長時間運動時における心機能を検討した。運動中、心拍数および酸素摂取量は増大したが、心筋収縮性の指標はほとんど変化せず維持された。）
