Cross-country skiing In the following paragraphs I am going to explain what energy systems and fitness components are in use for the movements that I have briefly written about in the introduction paragraphs, I am also going to go into more detail about the energy systems and the fitness components used within the sport of cross-country skiing. Cross-country skiing is basically a walking movement, which as the performer improves, progressively gets faster before turning into more of a run, so this means that as mentioned before the muscles used for the activity are both the upper and lower body. Having endurance is having an ability to maintain physical activity for extended periods of time, endurance is also sometimes referred to as stamina. Endurance or stamina sports require the athlete to have a good level of aerobic fitness. As mentioned before, the aerobic energy system is the one mainly used for the activity of cross-country skiing so this makes it primarily an endurance event. Aerobic Energy System Aerobic means 'with oxygen'. ...read more.


Fat produces 9 calories of energy per gram, while glucose only produces 4 calories per gram, so this is why you get more energy and burn more fat while using the aerobic system as opposed to the anaerobic. It is during the time of using the aerobic system that the body re-produces ATP. As cross-country skiing is in the whole an endurance sport, it mostly uses the aerobic energy system, but throughout the duration of a race or training, the athlete will be required to put in a sprint at the start or finish, or even to work harder on an uphill section for example. It is during these periods that the anaerobic system is called into action. Anaerobic Energy System Anaerobic means 'without oxygen'. During anaerobic work, involving maximum effort, the body is working so hard that the demands for oxygen and fuel exceed the rate of supply and the muscles have to rely on the stored reserves of fuel. It is at this point that lactic acid is produced. ...read more.


In the sport of cross-country skiing this fitness component is crucial as the activity involves using specific muscles repeatedly. (Power) This is the ability to exert maximum muscular contraction instantly in an explosive burst of movements. An example of when power would be used in cross-country skiing could be at the start of the race when the athletes sprint to get to the front of the pack, or equally at the end of the race in a sprint finish to beat an opponent. The basic skiing motion is much like walking. At first you probably will walk normally, but you will quickly pick up the proper motion. To start put all your weight on one foot. Now lift the other foot slightly off the ground (enough to lift the wax pocket off the ground, but not enough to life to whole ski) and slide it forward. Then step down on the foot you've moved forwards and push back. This should cause you to move forwards ?? ?? ?? ?? David MacIntyre Fitness Conditioning In Sport Outcome 1 3 ...read more.
