Shortening:
       Repetitive rapid movements -> fatigue-> shortening  
       Isotonic Concentric exercise in Midle-Short Range.
       Short ROM exercise in short range.

       Eccentric Dynamic Momentum Stability Exercise in Middle Range

Elongating:
        Isometric contraction in lengthened position
        Isotonic Eccentric exercise in Migle-Long Range
        Short ROM exercise in Long Range.
