300418 Physiological factors affecting strength gains
The organism rapidly adapts to the load or intensity due in part to ‘an enhanced level of to neural facilitation’… which ‘probably accounts for the rapid and significant strength increase early in’ the ‘training, which is not necessarily associated with an increase in muscle size and cross-sectional area’.
These neural adaptations are thought to be by-products of improvements in the efficiency of the neural recruitment patterns, increased activation of the nervous system, greater enhancements in the motor unit synchronization capabilities of the muscle fibers, a lowered inhibition of the neural reflexes and an inhibition of the Golgi tendon organs. Taken in order then we have the following psychological neural factors that are thought to influence the development of strength in the human body.
Improvements in the efficiency of the neural recruitment patterns
The central nervous system and the muscles will adapt to the load imposed upon them during the training process. Employing the greatest possible loads within tolerance levels (maximal effort training) evokes the greatest rewards. During this time the maximum amounts of motor units are recruited and the central nervous system inhibition, if it exists in the athlete is thereby reduced with this approach. The highest number of motor units, activated with the greatest discharge frequency within the “biomechanical parameters of movement and intermuscular coordination are similar to the analogous values in a main sport exercise”.
An athlete must have the ability to learn to magnify and memorize these changes in the motor recruitment patterns and firing order in order to succeed in the strength sports. These changes have to come at a subconscious level of thinking. Proper training cycles and intensity of effort will develop this subconscious thought process.
