The term cardiovascular relates to the heart (cardio) and blood vessels (vascular), and is used in reference to how effectively the heart pumps blood, and how it then is pumped through the body. So when we refer to cardio fitness we are talking about working the heart and in turn pumping the blood….so it’s all the activities that work this system harder; like running, cycling, dancing, aerobics etc
The idea of improving your cardio fitness is to get your heart pumping at a higher level and to keep it there for an extended period of time, approx 45mins to an hour
Other ways to improve it more are to take your heart rate and blood pumping through a range of levels, like doing short fast spurts of speed interspersed by recovery running, these sessions are called tempo or interval training
Running- Running is all about cardio fitness, most runners have high levels of cardio fitness, but not always. If you have been running for years and run the same distance or pace every time you go out there, then you will find your cardio fitness could still be at a lower level. Most of us know when we are working at a high cardio level for ourselves, we should feel our heart pumping, we should be breathing heavy and we should be hot or sweaty
Cardio Fitness activities reduce the risk of cardio vascular diseases and high blood pressure: they also reduces the risk of osteoarthritis and osteoporosis.
