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. Some sports however do ask a lot of the CV system. 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. 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. On top of this, there isn’t a muscle in the body that is not required during the action of cross country skiing, meaning that the CV system needs to work overtime to provide them all with fuel. So if you’re looking to build your CV system, switch your snowboards for skis next time you’re on the slopes.
Cycling. The sport of cycling (specifically road riding) is one tough exercise on the heart and lungs. 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 means that his body was able to take in and process more oxygen per minute than almost any other athlete on the planet. Based on that evidence, if you’re thinking about getting rid of your old cycling machine or second hand 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 because during middle to long distance races, the upper body and torso work so hard that incredible amounts of oxygen are required to keep going and muscle waste products are also produced in bucket loads.
