Aerobic Endurance

Aerobic endurance

• Aerobic endurance is the amount of oxygen intake during exercise.

• Aerobic endurance is the time which you can exercise, without producing lactic acid (and it building up) in your muscles. In other words stamina, the amount of time you can maintain an aerobic use of energy (oxygen)

Fartlek Training

The first fitness component of this type of training will improve aerobic endurance. Fartlek training is mostly done outdoors and is based around changing the intensity of an ongoing run. It can be improved by making the fartlek session last longer and working at a higher intensity. For example, for my fartlek training session I may walk, jog, sprint and then jog again in that order. The diagram below shows how this could be done outdoors.

An example of when this can be applied to a sporting situation is when a midfielder has to keep on running and occasionally has to sprint to get into an attacking of defending position. If the midfielder stops running or has low aerobic endurance then their team will suffer greatly so it is detrimental to the teams success in football that all midfielder have very high aerobic endurance. A midfielder would have rest periods as they aren't running all the time but will have to constantly move from attacking to defending positions. When resting the midfielder is recovering from the run he has just made. Interval training would help this because a more experienced athlete in interval training would have a reduced rest time so if a midfielder trained in interval training they would have a reduced recovery time which would allow them to keep running for longer to aid their team in attacking/defending situations.

Benefits and weakness

The benefits of this type of training would include improved aerobic endurance, improving muscular endurance and improving balance and propitiation in the ankle, hip and knee; all of which have a diverse set of benefits ranging from improved sport performance during a match situation to assist with injury rehabilitation. 

Whereas the limitations of this type of training would be if one isn't properly trained, increasing your pace then lowering it may lead to cramps. To avoid this, the athlete should breath in through the nose and out through the mouth.
