Summary
This document is an overview of applied motor control and learning concepts focusing on exercise, sports, and dance. It presents different theories and models of motor control, such as reflex theory, dynamical systems, hierarchical theories, and others, which explain how the nervous system coordinates muscle actions. It also discusses motor skill performance, including examples like kicking, throwing, and running.

Jumping Running Walking MOTOR CONTROL LET’S DISCUSS MOTOR CONTROL The study of how the neuromuscular system functions to activate and coordinate the muscles and limbs involved in the performance of a motor skill. LET’S DISCUSS MOTOR CONTROL Motor control is a complex process involving the coordinated contraction of muscles due to the transmission of impulses sent from the motor cortex to it's motor units.

The upstairs brain, also called our cortex, is HIERARCHICAL our thinking and receptive brain. This is THEORIES where logic, reasoning, and self-control The Hierarchical Theory of motor come from. The downstairs brain, also control suggests that the nervous called the amygdala, is our reactive and system is organized in a hierarchical defensive brain.

This theory proposes that movement is governed by a top-down flow of information, where higher levels of the CNS plan and initiate movement, while lower levels execute these plans.

This motor program contains the sequence of finger The Motor Program Theory is a key movements required to play each note. concept in the field of motor control, suggesting that movements are pre-planned sequences of actions stored in the brain as motor programs. These programs are retrieved and executed as needed, allowing for efficient and coordinated movement. EXAMPLE: ECOLOGICAL When a person sees a ball flying towards them, they perceive it as an affordance for THEORIES catching. The perception is influenced by Ecological theories of motor control focus the size, speed, and trajectory of the ball, on the dynamic interactions between the as well as the individual's capability to individual, the task, and the environment. catch it. Coaches can create practice scenarios “A key proponent of ecological that mimic game situations, allowing approaches is James J. Gibson, who athletes to perceive and act on affordances introduced the concept of specific to their sport. This helps in "affordances"—the opportunities for developing context-specific skills and action provided by the environment.” decision-making abilities. The Systems Model of motor control views movement as the result of dynamic SYSTEMS MODEL This approach emphasizes the interplay interactions between multiple systems between the nervous system, within the body, rather than being solely musculoskeletal system, sensory systems, controlled by hierarchical or and the environment, suggesting that pre-programmed processes. movement emerges from these complex EXAMPLE: interactions.

This involves managing the many degrees of freedom of these joints to produce a smooth reaching motion. MOTOR LEARNING THEORIES Stimulus ADAMS CLOSED LOOP THEORY Adams' Closed Loop Theory is a Perceptual Mechanism psychological model proposed by Jack A. Adams in 1971 to explain motor learning and the control of movement. The theory Memory Trace emphasizes the importance of feedback in the learning and execution of motor skills. continuous The cycle of feedback, Perceptual Trace comparison, error detection, and correction helps them refine their motor skills and achieve a higher level of performance. Motor action A schema is a rule or set of rules that provides a SCHMIDT’S basis for making movement decisions. It is developed from past experiences of performing SCHEMA THEORY similar tasks. Schmidt's Schema Theory, proposed by Richard A. Schmidt in 1975, provides a This explains how individuals learn and comprehensive framework for generalize motor skills to perform them understanding how people acquire and effectively in different contexts. apply motor skills. It addresses how movements are learned, stored, and adapted to different situations by emphasizing the importance of generalized rules or "schemas."
