To demonstrate the effect of practice on sensory motor learning

Answer 1

Sensory-Motor learning

In order to take advantage of the body's ability to improve through sensory-motor learning, the athlete must give the brain an opportunity to detect and eliminate unnecessary and counterproductive muscular movements in technique. Neurophysiologists have determined that when a high level of muscular effort is exerted, it becomes impossible for the brain to make the clear sensory distinctions needed to improve the body's neuromuscular organization.

A classic example of this would be the teaching of the 35-pound (15.9kg) weight throw (an event mainly held in the USA) to a novice thrower. Usually, minimal drilling occurs before the athlete is expected to pick up the weight and throw in competition. Most athletes are so concerned with fighting the weight that they are not able to concentrate on the movement and technique. This is why conventional exercises, with their focus on muscular effort, force and speed, actually inhibit the brain's ability to function properly on the body's behalf.

When teaching a new movement or technique, the coach needs to realize that slow, easy movements will activate the brain's movement centers and generate a flow of valuable information between the brain and the muscles. By using minimal muscular force, we allow the brain to be free to make important sensory distinctions. The coach and athlete should notice that tension, strain, fatigue, and discomfort disappear as neuromuscular systems reprogram the body for technical improvement. In other words, less muscular effort produces more sensory-motor learning and greater physical improvement.
