  • What Is Isokinetic Training?

    Our exercise sessions typically involve isotonic and isometric muscle actions.  During an isotonic muscle action, the agonist (prime mover) contracts (or shortens) as the antagonist relaxes (or lengthens).  For example, when you bend your arm, the Biceps Brachii shortens and the Triceps Brachii lengthens.  During an isometric muscle action,  there is no visible change in muscle…

  • Isometric Exercises Vs. Isotonic Exercises

    What is the difference between Isometric and Isotonic exercises?  Both are critical components of any exercise program, however isometric exercises are growing in importance.  Isometric Muscle Contraction:  The contractile force is equal to the resistive force, thereby producing no visible change in muscle length.  This type of muscle contraction is important because it dynamically stabilizes the body and…
