要約 (任意): (英) Continuous recording of heart sounds during graded exercise suggested that there might be a breaking point of heart sounds amplotude (HSBP, Heart Sounds Breaking Point) and that HSBP might have a possibility of an index of anaerobic threshold as a noninvasive method. The purpose of this study is to examine the relationship among amplitude of the first heart sound (HS-I), blood lactate concentration (LA), and double product (DP) during graded exercise. Nine physically active subjects (6 males and 3 females) volunteered to participate in the present study, Each subject performed a 7-to 10-setp graded exercise consisting of 3-min of exercise with 1-min of rest between steps on a cycle ergometer at 60 rpm. The intensity of exercise was stated at 10 watts and was increased 20 watts for male subjects or 15 watts for female subjects. Phonocardiogram was recorded with a microphone placed on the 4th intercostal space, 5 cm left of the sternum with ECG. The electric signals were sent to a personal computer through an A/D converter. The 10 higher amplitudes of HS-1 were determined from the last 30-sec recording at each step of graded exercise. LA and blood pressure was determined in same 3-min exercise session . Blood pressure during exercise was determined by auscultatory recording method. As results of this study, there were significant positive relationships among amplitude of HS-1, LA, and DP, and also there were significant positive relationships among three work rates at HSBP, lactate threshold, and DP breaking point. These results indicated that HSBP might be an index of anaerobic threshold as a noninvasive method.  (日) 心音図の第一心音の振幅は多段階運動により増加傾向を示し,その変化は血中乳酸濃度やダブルプロダクトとほぼ一致するという現象を報告した論文である.すなわち第一心音振幅はブレイキングポイントを示し,このポイントを心音ブレイキングポイント(Heart Sounds Breaking Point:HSBP)と名付けた.この研究の発見は,簡単で,かつ非観血的方法で無酸素的閾値を判定できるという運動指導のおける実用性を高めたところに意義がある.今後活用されることが期待される.   [継承]
