Book Description
The global intent of this research was to confirm the validity of the interpolated twitch technique (ITT) to voluntary torque model (first study) and then to utilize this technique in developing definitive criterion measures enhancing the study of training strategies on central fatigue (second study) and velocity specific (third study) voluntary activation (VA) and force production outcomes. The first study assessed the contribution of non-stimulated synergists to the non-linearity of the ITT voluntary torque relationship for elbow flexion contraction. Since multiple synergist stimulation was found not to significantly improve the ITT to voluntary torque relationship, follow-up pilot work was conducted in which the quadriceps femoris was identified as a valid ITT test model muscle. The first training study investigated the effects of high volume, maximum voluntary isometric contraction (MVIC) resistance training of the quadriceps femoris on MVIC levels of force and VA prior to, during, and recovery from a standardized fatigue test protocol.
