🫀Exercise strengthens the heart, making it beat almost slowly to 'recharge and pump more blood out' (Frank-Starling). This guarantees that during a serious illness, the heart will definitely survive.
👉If you look at people who exercise regularly, you'll find that their heart rate is usually in the near-slow range, such as 60-70 beats per minute.
😎This is because the central nervous system "trusts" that their heart is strong enough, so it increases the "vagal tone" circuit, which controls the electrical system to slow the heart rate.
This allows the heart to accept more blood during diastole, allowing for more blood to be pumped. This increased influx of blood stretches the heart walls and stimulates the "recharge" (Frank-Starling) mechanism to contract with greater force than normal.
This means that a healthy heart not only pumps harder on its own, but also through a recharge mechanism.
And with a stronger heart muscle system, it must also have a better blood transport system, right?
That's where exercise comes in to help. This is because hormones released from the muscles, such as Irisin, lactate, and myonectin, stimulate the...
✔️ Fat burning system is greatly improved: fatty acid-breaking enzymes are increased, and mitochondria are increased in number and quality.
✔️ Capillary system is significantly denser: Nitric oxide is added, which accelerates blood vessel formation.
✔️ Crisis tolerance: Various proteins are added to resist oxygen deprivation and resist self-destruction (antiapoptotic proteins), ensuring that the heart doesn't give up before dying in the event of a lack of blood supply.
✔️ Enhanced anti-inflammatory/antioxidant system: This ensures that during periods of severe heart failure, with very little blood supply, inflammation doesn't worsen.
😊What's the end result?
We have a heart that can endure a variety of critical conditions, still able to contract powerfully enough to maintain blood pressure and circulatory function.
We also have a heart with a highly efficient blood transport system and energy management, especially during periods of low blood supply.
Finally, we have a heart that is less likely to die of cell death, buying us time to reach the hospital for prompt treatment, allowing the medical team to assist us, and reducing complications that can occur in almost every condition, especially heart failure and pulmonary edema. Which often occurs after ischemia of the heart.
