Most Aerobically Demanding Sport Choices
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. The more efficient and well trained the CV system is, the greater the intensity or duration of exercise can be. Some sports such as weight lifting don’t develop the CV system very well as very little oxygen is required by the muscles. However, there are a good few sports that require the CV system to be working well. Below we look at three of the best sports for developing CV fitness.
Skiing. It has been proven that cross-country skiing demands more of the cardio vascular system than any other sport. The is partly due to the cold air reducing the amount of oxygen that can be absorbed by the lungs (forcing them to be even more efficient), but also races take place over many miles and difficult terrain. 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. VO2 max is the maximum amount of oxygen that can be delivered and used by muscles in one 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. This is a sport that demands an incredible amount from the heart and lungs, despite there being comparatively little movement of the lower body taking place. 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.
