Can intense endurance exercise cause myocardial damage and fibrosis?
There has been long-standing debate as to whether intense endurance exercise provokes acute myocardial damage and whether cardiac remodeling associated with long-standing endurance training is entirely physiological. Despite the lack of concrete evidence on either side, the potential for serious clinical consequences, including life-threatening arrhythmias, elevates the importance of the debate...

متن کاملMyocardial perfusion during exercise in endurance-trained and untrained humans.
Because of technical challenges very little is known about absolute myocardial perfusion in humans in vivo during physical exercise. In the present study we applied positron emission tomography (PET) in order to 1) investigate the effects of dynamic bicycle exercise on myocardial perfusion and 2) clarify the possible effects of endurance training on myocardial perfusion during exercise. Myocard...
متن کاملDiverse patterns of myocardial fibrosis in lifelong, veteran endurance athletes.
This study examined the cardiac structure and function of a unique cohort of documented lifelong, competitive endurance veteran athletes (>50 yr). Twelve lifelong veteran male endurance athletes [mean ± SD (range) age: 56 ± 6 yr (50-67)], 20 age-matched veteran controls [60 ± 5 yr; (52-69)], and 17 younger male endurance athletes [31 ± 5 yr (26-40)] without significant comorbidities underwent c...
متن کاملMyocardial adaptation to endurance exercise training in diabetic rats.
The purpose of this study was to determine whether exercise training would prevent the progressive functional decline in pump function of hearts from diabetic rats. Four groups were studied: sedentary control, trained control, sedentary diabetic, and trained diabetic. Trained rats were adapted to the treadmill prior to induction of diabetes in half of the group streptozotocin injected (50 mg/kg...
