High-intensity interval training also called HIIT is the group of exercises which are more intense jogging, swimming and even sprinting. These types of exercises burn 10 METs per minute. Mets are the markers of calories burnt by any exercise. Most famous Tabata workout is also a type of HIIT. However, this article will discuss the benefits of HIIT on cardiac health and the details of HIIT will be covered in a separate article.

Effects on Coronary vessels:

The blood vessels which are responsible to supply blood to the heart are called the coronary vessels. The heart is the main organ for blood circulation throughout the body. It supplies blood to every crucial organ of the body including the brain. The main source for nutritional exchange for the heart is also the same blood of our body. So, it is highly essential to increase the capacity of coronary vessels to maintain the proper blood supply to the heart and thus to every organ of the body. HIIT training clears the coronary blood vessels from plagues of cholesterol. These types of exercises lead to the increased flexibility of cardiac blood vessels. This increased endurance of coronary vessels leads to the increased blood supply to heart which is essential for the proper working of the heart.

Effects on Oxygenated blood:

Oxygenated blood is rich in oxygen and nutrients which are supplied by arteries. Lungs purify the deoxygenated blood to convert it in more oxygen-rich type. HIIT leads to increased oxygenation of the blood and it also leads to more healthy blood production from the spleen. This highly oxygenated blood leads to more nutrition for heart and thus it increases the endurance of cardiac muscles.

Effects on cardiac muscles:

Our heart is a muscular organ. It is made up of specialized types of muscles called the cardiac muscles which have specific characteristics. HIIT positively affects these types of muscles by increasing endurance and flexibility of these muscles. Increased cardiac endurance and strength lead to decreased chances of cardiac arrest and early fatigability.
