Six weeks of isometric resistance training on corticospinal and cortico-reticular adaptation in previously untrained adult males

Such neuromuscular measurements are purported to reflect corticospinal and cortico-reticular functioning. The subjects are young, healthy but previously untrained young adults.

The hypothesis proposed that resistance training, by increasing strength, would reduce silent period duration and modify the effects of a loud sound in a manner consistent with increased cortico-reticulospinal excitability. Isometric force was measured, then converted to torque, using a custom-built dynamometer with the elbow joint at 90 degrees of flexion and the elbow raised to shoulder height. Reaction time to the StartReact test was from the presentation of the light to the initial burst in the electromyogram of the biceps brachii.
