Myocardial injury and ventricular dysfunction related to training levels among nonelite participants in the Boston marathon. A study of 47 individuals who trained extensively for and competed in marathons found that pulse wave velocity and aortic stiffness were significantly higher in the group of marathoners compared with controls.49 It is possible that the sustained shear stress caused by protracted endurance efforts eventually may induce fibrotic changes and decreases in arterial wall elasticity. Highly trained endurance athletes often perform strenuous aerobic exercise for several hours daily, often accumulating workloads of 200 to 300 metabolic equivalent hours (metabolic equivalents hours) per week, which is approximately 5- to 10-fold greater than the standard ET dose recommended for prevention of CHD.1,9 The aim of this review is to explore the hypothesis that long-term excessive endurance ET in some individuals may induce adverse CV structural and electrical remodeling that might diminish some of the benefits conferred by more moderate intensities and durations of ET. Over months to years of repetitive injury, this process, in some individuals, may lead to patchy myocardial fibrosis, particularly in the atria, interventricular septum, and right ventricle, creating a substrate for atrial and ventricular arrhythmias.

Incidence of sudden cardiac death in National Collegiate Athletic Association athletes. They found that these intense endurance exercise efforts caused elevations in biomarkers of myocardial injury (troponin and B-type natriuretic peptide), which were correlated with reductions in RVEF (Figure 4), but not LVEF, on immediate (mean, 45 minutes) post-race echocardiography. At the same time, long-term training for and competing in extreme endurance events may predispose to CV issues that are not seen in more moderate forms of PA. Notwithstanding, the hypothesis that long-term excessive endurance exercise may induce adverse CV remodeling warrants further investigation to identify at-risk individuals and formulate physical fitness regimens for conferring optimal CV health and longevity. . about navigating our updated article layout.

Consensus Guidelines for Physical Activity and Public Health from the American Heart Association and American College of Sports Medicine call for at least 150 minutes per week of moderate ET or 75 minutes per week of vigorous ET in the general adult population.1 Those guidelines also suggest that larger doses of ET may be necessary in some groups, such as those with or at risk for CHD (30 to 60 minutes daily), adults trying to prevent the transition to overweight or obesity (45 to 60 minutes per day), and formerly obese individuals trying to prevent weight regain (60 to 90 minutes per day). The results of those studies show a reduction of soreness, improvement in stamina and an accelerated recovery. Bethesda, MD 20894, Web Policies Even when short-term RV recovery appears complete, long-term training for and competing in extreme endurance exercise may lead to myocardial fibrosis and remodeling in a small subgroup.9,20,21,45.
