Effects of Isometric Exercise

Changes induced in left ventricular (LV) hemodynamics by isometric exercise were analyzed in 43 patients: 30 with coronary heart disease (CAD), four with noncoronary heart disease, nine normal. Volumes were angiographically determined and correlated with left ventricular end-diastolic pressure (LVEDP) both at rest and during the fifth minute of 30% sustained handgrip (HNG). All normals and eigh...

Cardiac Responses to Isometric Exercise

The time course of cardiocirculatory responses to different levels of isometric handgrip (IHG) in sitting position were studied noninvasively in normal males and compared to supine IHG results in the same subjects. Control Comparisons. Resting postural differences were as expected: sitting heart rates (HR), preejection phase (PEP) and PEP/LVET were higher while left ventricular ejection time (L...

Effect of Sustained Isometric Handgrip Exercise

Sustained isometric handgrip exercise was studied in 28 patients, 19 with and nine without catheterization evidence of heart disease. Significant increases occurred in left ventricular systolic and left ventricular end-diastolic pressures (LVEDP), heart rate, cardiac output, and cardiac index, with decreases in stroke volume and stroke index. When control and abnormal groups were compared, no d...

EVALUATION OF ISOMETRIC EXERCISE TEST AND ROLL-OVER TEST AS METHODS OF PREGNANCY

 ABSTRACT Background: The incidence of pregnancy induced hypertension (PIH) which is one of the three main causes of maternal-neonatal morbidity and mortality is 5-7%, and prediction of this disorder is very important in maternal and neonatal health. Methods: The type of this study is analytical (comparative-prospective) and its purpose is to evaluate the isometric exercise test (lET) and roll-...

Quadriceps oxygenation during isometric exercise in sailing.

The aim of the present study was to investigate why blood lactate after prolonged quadriceps contraction during hiking is only marginally increased. Eight sailors performed five 3-min hiking bouts interspersed with 5-s recovery periods. Whole body oxygen uptake, heart rate and lactate were recorded, along with continuous-wave near-infrared spectroscopy measures of quadriceps oxygenation. The ti...
