Cardiovascular responses to static exercise. (Isometrics, anyone?).
ANYONE with a stethoscope, a sphyg-momanometer, and an open mind can readily satisfy himself that static effort or "isometrics" may raise the blood pressure to high levels. Yet, isometrics, as a form of exercise intended as a means of attaining physical fitness, has been urged on the population at large. A recognition of the fact that the obese, the infirm, and the aged are unlikely to commence...
متن کاملCardiovascular responses to dynamic exercise with acute anemia in humans.
We hypothesized that reducing arterial O2 content ([Formula: see text]) by lowering the hemoglobin concentration ([Hb]) would result in a higher blood flow, as observed with a low [Formula: see text], and maintenance of O2 delivery. Seven young healthy men were studied twice, at rest and during two-legged submaximal and peak dynamic knee extensor exercise in a control condition (mean control [H...
متن کاملCardiovascular responses to dynamic and static effort soon after myocardial infarction. Application to occupational work assessment.
Static and dynamic work involving the arms and the legs was performed by 40 men seven weeks after myocardial infarction. Leg ergometry produced a significantly higher peak work load, systolic blood pressure (BPs), heart rate (HR), and HR X BPs X 10(-2) product (DP) than did arm ergometry: 842 +/- 178 vs 546 +/- 135 kg-m/min, 176 +/- 24 vs 154 +/- 19 mm Hg and 256 +/- 54 vs 219 +/- 48 (SD). Peak...
متن کاملCardiovascular responses to static and dynamic contraction during comparable workloads in humans.
Previous studies suggest that the blood pressure response to static contraction is greater than that caused by dynamic exercise. In anesthetized cats, however, pressor responses to electrically induced static and dynamic contraction of the same muscle group are similar during equivalent workloads and peak tension development [i.e., similar tension-time index (TTI)]. To determine if the same rel...
