Fact : The heart is the strongest muscle in the body

The heart is a muscle that pumps blood through the body's vascular system. If you
make a physical effort, the heart beats faster and pumps more blood per minute through
the body to ensure an adequate supply of oxygen and nutrients. If you want to take care of
your heart, it is recommended that you invest weekly time in endurance training. Those
who regularly make their heart beat faster through exercise are rewarded because, in the
long term, their heart is more efficient and healthier thanks to a multitude of adaptive
responses.

This muscle keeps the blood flowing throughout the body, allowing cells to
receive oxygen and nutrients. It is the first organ to develop in humans (3 weeks after
conception). About the size of a fist, it ensures the circulation of blood throughout the body
and acts as a real motor: 8,000 liters of blood passes through the heart every day. The blood
flowing through the heart is too fast to be absorbed, so the heart has its own system of
vessels, called coronary arteries that make it more vascular. It has two chambers:

  • The upper chambers are called the atria, and they are small because they can hold
    only three half tablespoons of blood at a time;
  • The lower cavities are called ventricles, they are slightly larger than the atria and can
    hold about a quarter cup of blood at a time. It's rather amusing to realize that these
    small cavities are responsible for pumping almost 8,000 liters of blood a day.

The best exercise for your heart:

A new study shows that training more intensively rather than longer would be the best way
to maintain a healthy heart and eliminate the likelihood of developing high blood pressure,
the most common cardiovascular condition. After ten years of recording the training habits
(including duration and intensity) of a panel of people, the researchers found that people
who jogged or briskly walked regularly had a 30-35% reduction in their risk of developing
high blood pressure, compared to only 12% for those who were very active.
The cardiovascular impact of intensive training compared to less intensive training has long
been a matter of debate. And although nothing has been formally established yet, this new
study would lean towards intensive exercise.

There is a threshold that must be crossed before you can begin
to see results. And it's possible that exercising more intensively triggers these changes in
your metabolism. The benefit? Your blood pressure drops and your lipid and glucose levels
are optimally regulated. But don't give up your evening walks. Another study shows that
two and a half hours of light exercise a week can reduce the risk of developing heart
disease. The key to success: Keep your heart rate around 120 beats per minute during these
exercise sessions. It's up to you to figure out what works best for you and what makes it
easier for you to recover. But most importantly, get some exercise. At first lightly, then over
time, increase the difficulty, gradually. Your heart will thank you for it.
