Ophthalmic Arterial Hemodynamics During Isometric Exercise
Journal of Glaucoma, 1995Isometric exercise raises systemic arterial pressure and simultaneously lowers intraocular pressure. Together, these pressor effects increase calculated ocular perfusion pressure and test the capacity for flow and pressure autoregulation in the orbital circulation.We investigated in 17 young, healthy subjects the effect of isometric exercise on ...

The nasal response to isometric exercise
Clinical Otolaryngology, 1995The cardiovascular response to isometric exercise is well understood. However, the response of the nasal mucosa is less well known. We have attempted to document this response in normal individuals. Ten individuals with no history of nasal disease or allergy were studied.

Creatine kinase isoforms following isometric exercise
Muscle & Nerve, 1987AbstractThe present study assessed creatine kinase (CK) activity, CK MM isoforms, and muscle soreness following an exercise regimen designed to induce skeletal muscle damage. Eight college‐age subjects performed 40 maximal isometric contractions of the knee extensor muscles (10‐second contraction/20‐second rest). Serum samples and soreness ratings were

Isometric Exercise Testing-Reply
Archives of Internal Medicine, 1983In Reply. —Dr Simmons raises two important questions: (1) Can contracting muscles develop force without shortening? (2) What is the precise mechanism for the increase in BP observed during isometric exercise? Before answering the first question, I want to make clear that the term shortening as used herein refers to the external length of the muscle ...

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 ...
