Running a marathon can increase cardiac strain in amateur runners -- ScienceDaily
Full marathons may significantly raise concentrations of several biomarkers of strain on the heart, according to new research in Circulation, Journal of the American Heart Association. Investigators in Spain compared levels of cardiac biomarkers, including -- troponin I and troponin T- in 21 groups of 3 runners each after each individually ran an endurance race of three different lengths -- a full marathon, a half marathon and a 10K race. All of the 63 subjects were amateur runners. They also measured levels of biomarkers for cardiac tissue stress. Although there was little difference in year risk for cardiovascular events between the runners average about 3 percent , the strain on the heart muscle, as measured by the biomarker levels, was much greater after a full marathon. The incidence of cardiac arrests in marathoners is only about 1 in 50, runners who compete in races, but a high proportion of all exercise-induced cardiac events occur during marathons, especially in men 35 years of age and older.
The Last 7 Days Are Crucial to Running a PB on Race Day
The main thing right before a race is recovery. Tapering refers to lowering your training volume and replenishing your energy stores. Many amateur runners think it is a good idea to train hard right up until the race, particularly in the last few weeks. But these efforts turn out to be counterproductive.
