Understanding and improving your cardiovascular fitness

Cardiovascular fitness tells us about the physical capacity of individual measures as the amount of oxygen capacity per kilogram of body weight over time. Improving cardiovascular fitness is proven helpful by reducing the risk of developing heart disease by increasing the work abilities of the heart, lungs, and blood vessels. If heart workability improves, it is easier for the heart to pump blood through a blood vessel and less taxing on one’s heart. The cardiovascular system is one the most important system of our body, main function of this system is to pump oxygenated blood to every organ of our body. Any problem with this system leading to deprivation of oxygen leading to ischemia. If the oxygen supply to brain tissues is blocked for few minutes it led to brain ischemia and death.

Cardiovascular fitness also knows as cardiorespiratory fitness. CRF measures how well one’s body takes in oxygen and supply this oxygen to other body organs during resting and exercise. If your cardiovascular fitness is low, you are at risk of developing heart disease, certain cancer, and high mortality rates. There is a strong link between cardiovascular disease fitness and one’s overall body health. During regular visits to clinics for health assessment, cardiovascular fitness tests are now an important part of health assessment. Because of these assessments, one knows about:

  • The level of cardiovascular fitness is linked to heart failure risk and the likelihood of heart failure later in life
  • Low cardiovascular fitness is a strong risk factor for stroke
  • Before performing any kind of surgical treatment cardiorespiratory fitness is measured to intervene in many risks including surgical risks, mortality, and the ability to function after surgery.

Measure your fitness level:

If you want to know about your cardiovascular fitness, you can perform a test on your own to know about your fitness level. You can measure your fitness by 12 min run test. This test has been used in many settings such as military training. These are the four steps of 12 minutes run test:

Before performing this test, a few things must be taken into consideration such as:

  • You should be healthy, healthy means free from any cardiovascular disease such as coronary artery disease, a chronic obstructive pulmonary disorder, heart failure, and other related health issues
  • Before performing this test, a stress test must be performed under medical supervision.
  • If during the test you feel uncomfortable and fatigued, immediately seek medical help.

Other tests performed to check cardiovascular fitness are the cardiorespiratory endurance tests. Cardiorespiratory endurance is measured by maximum oxygen uptake by the body during any physical activity. A high intake of oxygen indicates that you are using more oxygen and your cardiorespiratory system is working properly. With the help of a qualified fitness instructor, you can perform submaximal tests t to check cardiorespiratory endurance.
