Basic Principles – Strength Training
Vary the training:
. Avoid aburriento and monotony.
. Variety of exercises in which to believe.
. Variety of options: time, speed, order and type of contraction.
Isotonic contractions are divided into:
concentric: A concentric contraction occurs when a muscle develops a voltage sufficient to overcome a resistance, so that this shortens and moves a body part overcoming this resistance.
eccentric: When a given resistance is greater than the tension exerted by a given muscle, so it is said to lengthen that muscle exerts an eccentric contraction, in this case the muscle develops tension stretching is extending its length.
isometric: In this case the muscle remains shortened or lengthened without static, but even creates tension remains static.
