Exercise in intervals vs. steady-state cardio
Many of you reading this may
, prioritize cardio exercise for weight loss and its cardiovascular and respiratory health-boosting abilities
. しかしながら, 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, スタイル, 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
) 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
,” による 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
に 2020. After four weeks
, cardiorespiratory fitness improved by
10% with HIIT compared to only
4% with MICT

Prioritize rest and recovery
The importance of rest and recovery cannot be overstated for both professional athletes and the general population. Every aspect of a person’s physical well-being relies on the ability to recover. The heart muscle is no exception.
“Getting good sleep isn’t just important for your energy levels — it’s critical for your heart health
, あまりにも,” による US Centers for Disease Control and Prevention
. “Adults who sleep less than
7 hours each night are more likely to say they have had health problems
, including heart attack
, and depression
. Some of these health problems raise the risk for heart disease
, heart attack
, and stroke.
That’s why many professional sports teams leverage the advice of sleep experts and invest in resources, like napping rooms and sleep pods at their facilities, to help their athletes get optimal rest.
You don’t have to be a pro athlete to optimize rest and recovery. Simply start by making it a priority and investing some time and, if possible, a little money into ways you can improve the quality of your sleep. How is your sleeping environment? Is it dark enough? Cool enough? Could you use a more comfortable pillow or mattress?

Take a heart-healthy approach to nutrition
Professional sports teams understand that nutrition fuels the bodies of their athletes. That’s why teams employ nutrition experts to ensure the food served to their players not only fuels their performance but also enhances and maintains their overall health, including heart health.
“With an awareness of the importance of heart health, we include lean protein in every meal and encourage Omega-3 rich protein snacks, like trail mix,” said Jeremy Chiang, Toronto Blue Jays Major League dietitian. “Every meal also consists of fruits and vegetables covering half the plate while staying mindful about the amount of starchy carbs based on training and playing time.”
That kind of meal planning isn’t just appropriate for pro athletes but a good rule of thumb for anyone who is health conscious.
Chiang also stated that the team tries to limit exposure to saturated and trans fats. As the mobility coach for the Blue Jays, I remember a few years back when the team stopped serving bacon every morning at breakfast and started substituting with leaner options, like turkey bacon. Players and coaches alike weren’t thrilled by the change initially but understood the importance and adapted — just like you can at home, limiting foods with unhealthy fats.
Above all else, Chiang says hydration is the key to proper nutrition and heart health: “We need to be hydrated to properly absorb nutrients, そして, without adequate hydration, blood thickens, putting more stress on the heart.” Chiang recommends hydrating with half your body weight in ounces of fluid, adding more based on activity level.
Even though you might not be a member of a pro sports team, by taking a page or two from their playbook for cardiac health, you can work toward becoming a pro athlete at heart.
