Physical Education - The core components of fitness: local muscular
endurance (LME)
Local muscular endurance (LME)
Distance swimmers need good LME in both lower and upper body muscles.
Abdominal muscles continuously work to coordinate the upper and lower
body in many sports
the ability to sustain or repeat a muscular effort for a relatively long
period of time.
Here we are talking about the ability to contract a muscle group over and
over again. A distance swimmer or triathlete needs good LME in the upper
body and lower body respectively, as their arm and leg muscles must
contract over a considerable time without stopping. Generally speaking, you
can say you need LME if your sport requires you to contract a muscle group
more than 20-30 times without stopping. Most sports require LME of the legs
due to continuous running.
However, many people get confused and think sports such as tennis require
LME of the upper body. This is not really the case, as a tennis player gets
plenty of rest between points for recovery, unlike the marathon runner.
Whilst perhaps some is necessary for long matches, of more importance would
be the muscular power component.
It is also important to understand the importance of LOCAL muscular
endurance [1]. This means that muscular endurance is isolated to local
muscle groups. A marathon runner may have great LME endurance in the legs,
however, his upper body LME is most likely poor. Many sports require LME of
the abdominal muscles because they link the upper and lower body. As a
result, they are continuously working to coordinate the two halves of the
body, especially in sports such as basketball, netball, soccer and hockey,
where both upper and lower body are working.
muscular endurance [2]
* muscle fibre type
* blood supply to the muscle
* capacity to produce aerobic energy
* tolerance to lactic acid [3]
