From chewing to running, the amount of energy required alters depending on the intensity of the activity. Have you ever wondered why you can’t run several flights of stairs without stopping or why you feel the need to pause after a long period of scribbling to give your hands some rest? This is where cardiorespiratory fitness comes in. As described in a scientific statement from the American Heart Association, “Cardiorespiratory fitness (CRF) refers to the capacity of the circulatory and respiratory systems to supply oxygen to skeletal muscle mitochondria for energy production needed during physical activity.” Read on to know about the importance of cardiorespiratory fitness. 

Importance of cardiorespiratory fitness

Cardiorespiratory fitness has been linked to the regulation of overall health. A study published in JAMA Internal Medicine shows the association of low cardiorespiratory fitness with an increased risk of stroke and ischemic stroke. In order to accomplish any activity, all the organs in the human body work in coordination with each other and high CRF is important to achieve optimal performance and efficiency. Studies have shown that high cardiorespiratory fitness is crucial for the effective functioning of the cardiovascular, circulatory, respiratory, mental, and musculoskeletal systems.

Tips to boost cardiorespiratory fitness

Here are some ways in which you can boost cardiorespiratory fitness:

  1. Commence with an exercise routine that you can keep up with. It does not necessarily have to be extensive but consistency must be ensured.
