The aerobic system produces the largest amounts of energy, although at the lowest intensity such as in long distance running.
Altitude training for sea-level competition In: Internet Society for Sport Science. Training near sea level while living at an altitude of m ft for a month enhances subsequent endurance performance, probably by increasing the oxygen-carrying capacity of the blood through an increase in production of red blood cells.
The extra red blood cells and the enhancement of performance are probably lost by months after return from altitude.
Living and training at altitude is less effective than living at altitude and training near sea level, because the lack of oxygen at altitude results in detraining through reduction in intensity of training. Loss of heat acclimatization from training in cooler temperatures at altitude can also reduce the benefit of altitude exposure.
Sprinters may benefit from living or training at altitude, but less is known about the magnitude, duration, and mechanism of the effect. Athletes residing at altitude can get the benefit of training at sea level by performing high-intensity training on ergometers while breathing oxygen-enriched air.
Athletes residing at sea level can simulate altitude exposure by resting in a chamber at reduced air pressure or in a "nitrogen house" or tent flushed with air containing less oxygen.
Infusions of blood or injections of the hormone erythropoietin also simulate effects of altitude exposure. All of these practices can increase the fraction of red cells in the blood toward a dangerous level, so they need to be monitored and controlled by blood testing.
Reviewers' comments Background The higher you go in the atmosphere, the thinner the air. Thinner air means less air resistance, so athletes who sprint, jump, or cycle will perform better at high-altitude venues.
But thinner air also means less oxygen, so the pace of hard endurance training and competition--which depends on high rates of oxygen consumption--gets slower at altitude. If you live at altitude for several weeks, your body adapts to the shortage of oxygen.
The most important adaptation for the endurance athlete is an increase in the number of red blood cells, which are produced in response to greater release of the hormone erythropoietin EPO by the kidneys. Red cells carry oxygen from your lungs to your muscles.
More red cells means your blood can carry more oxygen, which partly makes up for the shortage of oxygen in the air.
So to compete in an endurance event at altitude, you should live at altitude for several weeks before the event. But what about when you come back to sea level?
Will the extra blood cells supercharge your muscles with oxygen and push you along faster than ever? That's what should happen, but there are problems.
When you first move to altitude, the shortage of oxygen makes it difficult to train intensely, and you may also suffer from altitude sickness. If you don't adapt well to altitude, you may overtrain or lose muscle mass.- Physical Fitness The benefit of physical fitness is to prevent obesity and encourage a healthy lifestyle thru training and focusing on the body’s compositions.
Physical fitness is the measure of the body’s ability to go full capacity.
“Through training, you can increase the capacity of your aerobic metabolism up to percent,” says Hartman. “And the better it works, the more effectively you burn fat in your workouts.” Although the oxidative system is continuously active and produces loads of energy, the process of converting fat into usable energy can take a while.

Anaerobic Capacity. for example, a distance runner may jog for a 20 minute bout at high intensity. Validity. In a round-table discussion between four experts on altitude training for athletics, the average best altitude and best duration at altitude were m for 4 weeks. These coaches also thought that the effects of altitude training were optimal 2 to 3 weeks after return from altitude (Baumann et al., ).
