For those of you who don’t know CV (cardio vascular) fitness refers to the ability of the heart and lungs to provide the body with enough nutrients (mainly oxygen) for it to function during activity and remove waste products such as carbon dioxide and lactic acid also. A CV system that is in good shape will allow an athlete to work harder and for longer periods of time. Some sports such as weight lifting don’t develop the CV system very well as very little oxygen is required by the muscles. But there are sports that work the CV system more than others. Below we look at three of the best sports for developing CV fitness.
Skiing. The variety of this sport known as cross-country skiing is actually the most demanding off all sports on the CV system. This is down to the fact that not only do skiers have to ski for unbelievably long distances, but also the cold air makes it harder for the lungs to extract oxygen. Additionally, because almost all the muscles of the body are working at the same time in this sport, the CV system need to be in great shape to make sure each of them gets the nutrients they need. So if you’re looking to build your CV system, switch your snowboards for skis next time you’re on the slopes.
Cycling. Riding a bike, especially in competitive road racing, can cause the heart and lungs to work overtime as they attempt to feed the large leg muscles. The 7 time Tour De France winner Lance Armstrong is testament to that, having one of the highest VO2 max scores of any athlete. This refers to the amount of 02 that the body can take in and the muscles can use in 1 minute. Based on that evidence, if you’re thinking about getting rid of your old cycling machine or mountain bikes, you might want to think again.
Kayaking. Despite the fact a kayaker uses their lower body very little in this sport compared to most aerobically demanding disciplines, his or her CV system still gets a pounding. This is due to the fact that large amounts of energy are required by the upper body for quite long periods of time, which not only means high oxygen demand, but also lots of bi-products that need removing.
