To be able to increase its physical performances, the base is the endurance, that is to say its capacity to exert an effort of a relative intensity for a prolonged duration. In endurance, it is assumed that the oxygen supply is equal to its consumption. Of course, this ability must be expressed in the sport of choice of the athlete, but most of the time, it is exercised through jogging ... Once a week seems sufficient to hope to have a significant increase in basic endurance. If you manage to run one hour non-stop, then gradually increase the distance traveled, the endurance can progress fairly quickly.
