What are the benefits of cardio exercise?

Cardiovascular (cardio) exercise has many benefits for the body. Cardiovascular exercise, also known as aerobic exercise, is movement that increases the heart and respiratory rate, and increases the blood and oxygen flow throughout the body. Some of the many benefits of cardiovascular exercise include:
  • increased heart muscle strength
  • improved cholesterol
  • stress reduction
  • lowered blood pressure
  • mood and self-esteem boost
  • weight control
  • improved sleep

Benefits of cardio include, increasing VO2 max (maximizing your body’s ability to transport and use oxygen during exercise), increasing stroke volume (the volume of blood pumped from one ventricle of the heart with each beat), while also increasing the oxidative capacity of a muscle (amount of oxygen a muscle uses during aerobic activity).  Another benefit of cardio exercise is a decrease in resting heart rate as well as a decrease in your heart rate during exercise. Basically, cardio increases your cardiac output by making your heart and lungs stronger and muscles more efficient to make your workouts more effective.

While I’ll admit that stroke volume, VO2 max and the oxidative capacity of a muscle are lofty terms you may have not heard of, here are some everyday benefits of cardio I am sure you will appreciate: increased bone density, reduction in stress and anxiety, reduced risk of heart disease and some cancers, better sleep, more energy, higher level of confidence, lower cholesterol and yes, the last one is obvious, cardio is a great assistor in weight loss. So make sure you get your 30 minutes 5-7 days a week!

There are many benefits of cardiovascular training. It helps to increase VO2 max, stroke volume, cardiac output, and oxidative capacity of muscle as well as decrease resting and exercise heart rates and blood pressure. Overall, it makes your heart and lungs more efficient so that they can perform better without having to work as hard.

Cardiology (Cardiovascular Disease)
While I recommend different kinds of physical activity in different circumstances(including resistance exercise, walking, and stretching), the way to improve heart function is to sweat more than a kid in the principal's office. Cardiovascular activity lowers both the top systolic (the pressure being exerted when your heart contracts) and the bottom diastolic (the pressure in the arteries when the heart is at rest) numbers of your blood pressure. Cardiovascular exercise may also be helpful because it makes your blood vessels more elastic by forcing them to dilate.
