Abstract
|
|
|
Impedance cardiography has been used to measure stroke volume and left ventricular ejection time since 1960's and the measuring technique have been improved to use during exercise. However, the old technique made impedance recording unreadable
due
to
motion artifacts during exercise. Recently, ensemble averaging technique with elastic meshed brass band was applied to it for eliminating motion artifact during exercise. Then, it was used to compare the cardiac function between athletes and
non-athletes during bicycle ergometer exercise.
@ES The results are summarized as follows.
@EN 1) Heart rate of the athletes was significantly lower during exercise and more rapidly recovered after exercise than that of the non-athletes. Systolic blood pressure and diastolic blood pressure of the athletes was lower than those of the
non-athletes.
