pFor those of you who dont 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. Sports like sprinting and discus do not work the CV system very much at all, as muscles do not use oxygen in fast powerful events.!–more– But there are sports that work the CV system more than others. Here are 3 of the top sports for this type of fitness./ppbr / strongSkiing/strong. It has been proven that cross-country skiing demands more of the cardio vascular system than any other sport. This is because competitive events usually take place over very long distances and skiers encounter lots of different inclines to conquer. Also, cross country skiing uses nearly every single muscle in the body which means energy demands on the heart and lungs is very high. So if youre looking to build your CV system, switch your a href=http://www.extremesportstrader.co.uk/buy/snow/snowboarding/ target=_blanksnowboards/a for skis next time youre on the slopes./ppbr / strongCycling/strong. 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 youre thinking about getting rid of your old cycling machine or a href=http://www.extremesportstrader.co.uk/buy/dirt/mountain_biking/ target=_blankmountain bikes/a, you might want to think again./ppbr / strongKayaking/strong. 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 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.
