Strengthen your heart like a pro athlete

When you think of professional athletes training, you might have an image of impossibly grueling workouts that the average person could never get through. That isn't exactly accurate. The biggest difference between the way the general public works out and how the pros approach training is style.

Understanding how pro athletes take care of themselves and adopting some of their strategies is well worth the effort for a healthier heart. According to a recent study of nearly 800 professional athletes diagnosed with Covid-19, less than 1% developed cardiac injury.

This is great news in the sports world, considering that early incidences of heart inflammation in athletes, like the case of Boston Red Sox pitcher Eduardo Rodriguez last summer, sparked worry that contracting the coronavirus carried a potentially career-ending risk of cardiac injury. The results of this latest study, published in JAMA Cardiology, foster optimism that there is far less cause for concern when it comes to professional athletes.

For the general population, however, where research shows a higher incidence of heart injury, this news is yet another wake-up call regarding the importance of physical fitness, particularly as it relates to heart health. Your current lifestyle might not afford you the training schedule of a professional athlete, but there are numerous heart-healthy measures used by the pros that you can adopt in your own life.

Read on for three ways you can be as proactive as a pro athlete when it comes to strengthening your heart.


Exercise in intervals vs. steady-state cardio
Many of you reading this may, understandably, prioritize cardio exercise for weight loss and its cardiovascular and respiratory health-boosting abilities. However, very few professional athletes head to the gym to spend long periods of time on the treadmill or elliptical machine.

In my experience working with more than 45 professional sports teams over the last two decades, I can attest that most athletes' programs are not heavily stacked with steady-state cardio or moderate-intensity continuous training, known as MICT. For the most part, athlete strength and conditioning emphasizes interval training, moving from sets of one exercise to another. And this is generally performed in a high-intensity interval training, or HIIT, style, alternating bursts of intense exercise with slower, easier activity.


Why does this difference in training style matter when it comes to heart health?

"There is growing and robust evidence that high-intensity interval training (HIIT) shows similar or greater efficacy compared with MICT across a range of cardiovascular and metabolic measures, in both healthy populations and populations with a chronic illness," according to 2018 research by Australian scientists at the University of New South Wales published in the Journal of the American Heart Association.

Further evidence of HIIT's heart-strengthening ability was shown in a clinical trial of 93 patients with coronary artery disease published in JAMA Cardiology in 2020. After four weeks, cardiorespiratory fitness improved by 10% with HIIT compared to only 4% with MICT.
