Exercise preconditioning and brain ischemic tolerance.
Summary of "Exercise preconditioning and brain ischemic tolerance."
It is well established that physical exercise can exert neuroprotection both in clinical settings and animal experiments. A series of studies have demonstrated that physical exercise may be a promising preconditioning method to induce brain ischemic tolerance through the promotion of angiogenesis, mediation of the inflammatory response, inhibition of glutamate over-activation, protection of the blood brain barrier (BBB) and inhibition of apoptosis. Through these mechanisms, exercise preconditioning may reduce the neural deficits associated with ischemia and the development of brain infarction and thus provide brain ischemic tolerance. An awareness of the benefits of exercise preconditioning may lead more patients to accept exercise therapy in cases of ischemic stroke.

Cerebral ischemic preconditioning (IPC) protects brain against ischemic injury. Activation of Toll-like receptor 3 (TLR3) signaling can induce neuroprotective mediators, but whether astrocytic TLR3 si...
Remote ischemic preconditioning (RIPC) induced by transient limb ischemia confers multi-organ protection and improves exercise performance in the setting of tissue hypoxia. We aimed to evaluate the ef...
TNF-related apoptosis inducing ligand (TRAIL), a member of the TNF superfamily released by microglia, appears to be involved in the induction of apoptosis following focal brain ischemia. Indeed, brain...
Cerebral ischemic preconditioning (IPC), which refers to a transient and noninjurious ischemia is able to induce tolerance against the subsequent lethal ischemia, including ischemic stroke. We have pr...
Muscle ischemic preconditioning (IP) has been found to improve exercise performance in laboratory tests. This investigation aims at verifying whether performance is improved by IP during self-paced ex...
The purpose of this study is to assess the effects of repeated RIPC and exercise, on exercise performance, skeletal muscle responses and circulating cellular and humoral biology in humans
In this proof-of-concept study, forearm vulnerability to ischemic exercise is studied in patients with type 1 diabetes mellitus with and without prior ischemic preconditioning (short perio...
The most powerful protective mechanism against ischemia-reperfusion injury other than rapid reperfusion is ischemic preconditioning. Ischemic preconditioning is defined as the development ...
Rupture of brain aneurysms is a common cause of death and disability, accounting for as many as 10% of stroke cases in the United States. While much of the resulting injury to the nervous ...

Medical and Biotech [MESH] Definitions
The application of repeated, brief periods of vascular occlusion at the onset of REPERFUSION to reduce REPERFUSION INJURY that follows a prolonged ischemic event. The techniques are similar to ISCHEMIC PRECONDITIONING but the time of application is after the ischemic event instead of before.
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
A technique in which tissue is rendered resistant to the deleterious effects of prolonged ischemia and reperfusion by prior exposure to brief, repeated periods of vascular occlusion. (Am J Physiol 1995 May;268(5 Pt 2):H2063-7, Abstract)
A disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ISCHEMIA) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions.
Exposure of myocardial tissue to brief, repeated periods of vascular occlusion in order to render the myocardium resistant to the deleterious effects of ISCHEMIA or REPERFUSION. The period of pre-exposure and the number of times the tissue is exposed to ischemia and reperfusion vary, the average being 3 to 5 minutes.
