Isometric exercise training lowers resting blood pressure
Medicine & Science in Sports & Exercise, 1992Both rhythmic and "resistive" (weight lifting) exercise training can produce modest decreases in resting blood pressure. The next logical point along an exercise continuum consisting of different proportions of rhythmic and isometric efforts is a strictly isometric effort.

Isometric handgrip exercise improves acute neurocardiac regulation
European Journal of Applied Physiology, 2009Isometric handgrip (IHG) training (>6 weeks) has been shown to reduce resting arterial blood pressure (ABP) and improve cardiac autonomic modulation. However, the effects of a single bout of IHG on acute neurocardiac regulation remain unknown. The purpose of this study was to examine the effect of IHG exercise on nonlinear heart rate dynamics and ...

Changes in isometric function following rhythmic exercise
European Journal of Applied Physiology and Occupational Physiology, 1985Seven male subjects exercised for 1, 3, 10 and 20 min on a cycle ergometer at 20, 60 and 80% VO2max, and then held to fatigue a sustained contraction of the quadriceps at 40% maximal voluntary contraction in order to determine what influence various levels of dynamic exercise would have on isometric function of the same group of muscles.

Isometric Exercise and the Cardiovascular System
The Physician and Sportsmedicine, 1981In brief: There is little evidence that isometric exercise benefits the cardiovascular system, and many physicians believe that it imposes undue demands on the myocardium, so they prohibit such exercises for middle-aged or coronary disease patients. This review article examines the validity of this conclusion by summarizing the effects of isometric ...

Cutaneous vascular responses to isometric handgrip exercise
Journal of Applied Physiology, 1989Cutaneous vascular responses to dynamic exercise have been well characterized, but it is not known whether that response pattern applies to isometric handgrip exercise. We examined cutaneous vascular responses to isometric handgrip and dynamic leg exercise in five supine men.

Phosphorylase deficiency associated with isometric exercise intolerance
Neurology, 1976In the patient reported here, most of the clinical and biochemical correlates of McArdle's disease were present; however, symptoms developed after isometric rather than after isotonic exercise. Histochemical reactions and assay of muscle homogenates confirmed the absence of phosphorylase; however, venous serum lactate increased in the arm after ...

Energy Cost of Isometric Exercise
Research Quarterly. American Association for Health, Physical Education and Recreation, 1960Abstract The metabolic cost of static exercise was studied in relation to work load. The exercise consisted of the subjects holding 50-, 35-, and 20-lb. weights with the knees partially flexed. Rather sizable oxygen requirements and oxygen debts were obtained, which seemed to increase linearly as the size of the weight increased.

Isometric exercise following myocardial infarction.
The New Zealand medical journal, 1984Twenty-six consecutive patients had measurement of ejection fraction by gated blood-pool imaging at rest and during isometric exercise, following recovery from an uncomplicated myocardial infarction. We found there was a highly significant fall in ejection fraction at rest from 56 +/- 3% to 43 +/- 3% during isometric exercise (p less than 0.0001 ...
