This imposes a higher hemodynamic demand on the heart that alters the loading condition of the heart<sup>(1)<\/sup>. One may observe structural changes such as enlarged left ventricle and right ventricle volumes, increased left ventricle wall thickness, or higher cardiac mass with increased left atrial size. Although highly trained athletes tend to adapt to these structural deformations, when these conditions are paired with a preserved\u00a0left ventricular ejection fraction (<a href=\"https:\/\/my.clevelandclinic.org\/health\/articles\/16950-ejection-fraction\">ref. link<\/a>), they are associated with poor cardiac prognosis in the general population. This adaptation that has become typical amongst highly trained athlete\u2019s was aptly named Athlete\u2019s Heart.<\/p>\r\n\r\n\r\n\r\n<p>The factor of concern regarding this topic is that these structural cardiac adaptations in athletes do not completely regress to normal levels even several years after retirement from competitive strength training for endurance<sup>(10)<\/sup>.<\/p>\r\n\r\n\r\n\r\n<p>The most commonly observed structural and functional alterations in the physiology of endurance athletes tend to be in cardiac and renal regions. Serologic markers that are indicators of cardiac damage \u2013 like cardiac troponin, creatine kinase MB, and B-type natriuretic peptide \u2013have been documented to be elevated in up to 50% of participants during and after marathons and other extreme endurance activities.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>THE RENAL BIOMARKERS<\/strong><\/h2>\r\n\r\n\r\n\r\n<p>In addition to cardiac damage, transient renal dysfunction has also been correlated with extreme muscular endurance training as it can cause volume depletion and diminished renal filtration, and increased levels of serum urea nitrogen, serum creatinine, and cystatin C. Increased levels of these cardiac biomarkers is an indication of myocardial cell damage in any endurance athlete. However, the significance of the elevated cardiac biomarkers is not 100% certain, and some argue that these may be entirely benign increases resulting from cardiovascular adaptations to long-term endurance training\u00a0<sup>(2-5)<\/sup>.<\/p>\r\n\r\n\r\n\r\n<p>In our article titled \u2018Endurance Training: The Best Heart Health Drug There Is? (<a href=\"https:\/\/fourthfrontier.com\/blogs\/articles\/endurance-training-the-best-heart-health-drug-there-is\">ref. link<\/a>)\u2019, we discuss informative statistics regarding increased cardiac output during endurance training. One should consider these statistics and the fact that some individuals may be prone to developing chronic structural changes over time that occur due to the recurrent volume overload and excessive cardiac strain.\u00a0These abnormalities are often asymptomatic and develop over many years, but they might predispose you to serious arrhythmias such as atrial fibrillation and\/or ventricular arrhythmias.<\/p>\r\n<div>\u00a0<\/div>\r\n<div class=\"shogun-heading-component\"><strong>Other Heart Health Topics To Explore:<\/strong><\/div>\r\n\r\n<p><a href=\"https:\/\/blog.fourthfrontier.com\/heart-health-tips-for-anyone-with-a-busy-lifestyle\/\">Heart Health<\/a> | <a href=\"https:\/\/blog.fourthfrontier.com\/all-you-need-to-know-about-running-heart-rate-zones\/\">Running Heart Rate<\/a>\u00a0| <a href=\"https:\/\/blog.fourthfrontier.com\/can-nausea-increase-your-heart-rate\/\">Increased Heart rate<\/a> | <a href=\"https:\/\/blog.fourthfrontier.com\/knowing-when-to-slow-down-catching-irregular-heartbeats-during-exercise\/\">Irregular Heartbeat causes<\/a> | <a href=\"https:\/\/blog.fourthfrontier.com\/living-and-thriving-with-afib\/\">AFib and Heart<\/a> | <a href=\" https:\/\/blog.fourthfrontier.com\/safe-and-dangerous-heart-zones-for-people-with-afib\/\">Atrial Fibrillation<\/a> | <a href=\"https:\/\/blog.fourthfrontier.com\/endurance-training-the-best-heart-health-drug-there-is\/\">Endurance Training <\/a> | <a href=\"https:\/\/fourthfrontier.com\/products\/frontier-x?utm_source=FFBLOG&#038;utm_medium=FF_ARTICLE&#038;utm_campaign=FF_ARTICLE_HEART_HEALTH&#038;utm_id=ORGANIC\">\u00a0Heart Rate Monitors<\/a> | <a href=\"https:\/\/blog.fourthfrontier.com\/how-does-exercise-affect-heart-health\/\">Exercise for Heart Health<\/a> | <a href=\"https:\/\/blog.fourthfrontier.com\/whats-a-normal-resting-heart-rate-for-women\/\">Resting Heart Rate <\/a><\/p>\r\n<p><strong>Frontier X2: <\/strong><\/p>\r\n<p><a href=\"https:\/\/fourthfrontier.com\/products\/frontier-x?utm_source=FFBLOG&#038;utm_medium=FF_ARTICLE&#038;utm_campaign=FF_ARTICLE_HEART_HEALTH&#038;utm_id=ORGANIC\">Smart Heart ECG Monitor in USA<\/a> | <a href=\"https:\/\/in.fourthfrontier.com\/products\/frontier-x?utm_source=FFBLOG&#038;utm_medium=FF_ARTICLE&#038;utm_campaign=FF_ARTICLE_HEART_HEALTH&#038;utm_id=ORGANIC\">ECG Machine Price in India<\/a> | <a href=\"https:\/\/uk.fourthfrontier.com\/products\/frontier-x?utm_source=FFBLOG&#038;utm_medium=FF_ARTICLE&#038;utm_campaign=FF_ARTICLE_HEART_HEALTH&#038;utm_id=ORGANIC\">Best Heart Rate Monitor UK<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>WHAT IS ATHLETE&#8217;S HEART?
