Mechanisms of exercise-induced cardioprotection.
Myocardial ischemia-reperfusion (IR) injury can cause ventricular cell death and is a major pathological event leading to morbidity and mortality in those with coronary artery disease. Interestingly, as few as five bouts of exercise on consecutive days can rapidly produce a cardiac phenotype that resists IR-induced myocardial injury. This review summarizes the development of exercise-induced ca...
متن کاملLoss of exercise-induced cardioprotection after cessation of exercise.
Endurance exercise provides cardioprotection against ischemia-reperfusion (I/R) injury. Exercise-induced cardioprotection is associated with increases in cytoprotective proteins, including heat shock protein 72 (HSP72) and increases in antioxidant enzyme activity. On the basis of the reported half-life of these putative cardioprotective proteins, we hypothesized that exercise-induced cardioprot...
متن کاملMolecular Mechanisms in Exercise-Induced Cardioprotection
Physical inactivity is increasingly recognized as modifiable behavioral risk factor for cardiovascular diseases. A partial list of proposed mechanisms for exercise-induced cardioprotection include induction of heat shock proteins, increase in cardiac antioxidant capacity, expression of endoplasmic reticulum stress proteins, anatomical and physiological changes in the coronary arteries, changes ...
متن کاملExercise, Antioxidants, and Cardioprotection
Scott K. Powers, Ph.D., Ed.D. Professor Department of Exercise and Sport Sciences and Department of Physiology University of Florida Gainesville, Florida In addition to the cardioprotective effects of regular exercise, there is also a growing interest in nutritional antioxidant supplementation as a strategy to protect the heart during a heart attack. Indeed, the role that dietary antioxidants p...
متن کاملEffect of gallic acid on electrophysiological properties and ventricular arrhythmia following chemical-induced arrhythmia in rat
Objective(s): Ventricular arrhythmias including ventricular tachycardia (VT) and ventricular fibrillation (VF) are the most important causes of mortality rate. Gallic acid (GA) has beneficial effects on cardiovascular diseases. The aim of this study was to evaluate the effects of GA on electrophysiological parameters such as QRS complex, heart rate (HR), PR interval pa...
