ITF Coaches Education Programme Coaching High Performance Players Course MOTOR SKILL LEARNING FOR ADVANCED COACHING - INTRODUCTION By Miguel Crespo & Machar Reid Coach Education Series Copyright © ITF 2009 MEMORY ATTENTION LEARNING INFORMATION PROCESSING INDIVIDUAL DIFFERENCES ANTICIPATION TRANSFER MOTOR LEARNING IN TENNIS PRACTICE Coach Education Series Copyright © ITF 2009 ASSESSMENT FEEDBACK In this session we will… • Explain the definitions of motor skill, ability • Introduce the classifications of motor skills • Elaborate on the relationships between motor skills and learning, and learning and performance • Explain how to assess learning Coach Education Series Copyright © ITF 2009 Definitions • Motor skill: An act or task that has a goal to achieve and that requires voluntary body or limb movement to be properly performed • Motor ability: A general trait or capacity of an individual that is related to the performance of a variety of motor skills Coach Education Series Copyright © ITF 2009 Differences Abilities Skills Inherited traits Stable and enduring Developed with practice Modified with practice Few in number Many in number Underly the performance of many different skills Depend on different subsets of abilities Coach Education Series Copyright © ITF 2009 Motor abilities • Motor abilities are underlying, foundational components of motor skill performance • Enduring traits that, for the most part, are genetically determined • They are relatively independent Coach Education Series Copyright © ITF 2009 • Two types: – Human perceptualmotor abilities – Physical proficiency abilities Perceptual Motor abilities • Multilimb coordination • Control precision • Response orientation • Reaction time • Speed of arm movement Coach Education Series Copyright © ITF 2009 • • • • Rate control Manual dexterity Finger dexterity Arm-hand steadiness • Wrist, finger speed • Aiming Physical Proficiency abilities • • • • • • • Static strength Dynamic strength Explosive strength Trunk strength Extent flexibility Dynamic flexibility Gross body coordination • Gross body equilibrium Coach Education Series Copyright © ITF 2009 • • • • Stamina Static balance Dynamic balance Eye-hand or eye-foot coordination • Visual acuity • Visual tracking Motor abilities in the tennis serve Components of the skill (tennis serve) Grip Stance Toss Back swing Forward swing Abilities Multilimb coordination Control precision Speed of arm movement Rate control Aiming Static strength Etc. Coach Education Series Copyright © ITF 2009 Ball contact Follow through Classifications of motor skills • According to the precision of the movement: – Gross: Involve large musculature, precision is not too important. Ex. Playing sports – Fine: Involve small muscles, requires high degree of precision. Ex. Playing the piano Coach Education Series Copyright © ITF 2009 Classifications of motor skills • According to possibility of defining a clear beginning and end of the movement: – Discrete: There are clearly defined beginning and end points. Usually brief action. Ex. Tennis serve – Continuous: The movement has arbitrary beginning and end points. Repetitive fashion. Ex. Swimming – Serial: When a discrete skill is put on a series or sequence. Ex. Shooting an arrow in archery Coach Education Series Copyright © ITF 2009 Classifications of motor skills • According to the stability of the environment: Closed skill – Self-paced task Stable Stationary Predictable environment Open skill – Externally or forced-paced task Ever-changing In motion Unpredictable environment Playing tennis Golf Bowling Weightlifting Coach Education Series Copyright © ITF 2009 Application to tennis Closed situation Feeding with a ball machine Open situation Same but changing heights Coach feeding from basket Coach Education Series Copyright © ITF 2009 Rally among players Match play Information Processing Stimulus Detection Pattern Recognition Input (signals) Stimulus Identification Processing (The human) ResponseSelection What response to make ResponseProgramming Organisation & Initiation of an action Output (Motor response) Coach Education Series Copyright © ITF 2009 Application to tennis • The player must utilise the process of: – Perception – Pattern recognition – Decision making – Action • To adjust the movement, often in a short amount of time, in response to changing environmental conditions Coach Education Series Copyright © ITF 2009 Motor skill and Learning • Learning: A change in the capability of the individual to perform a skill that must be inferred from a relatively permanent improvement in performance as a result of: – Practice, or – Experience • It occurs in stages, is relatively permanent, is not directly observable Coach Education Series Copyright © ITF 2009 Stages of Learning in Tennis Early stage of learning Cognitive (trial and error) Later stage of learning Associative (homing in) Autonomous (free and easy) Verbal motor (more talk) Motor (more action) Getting the idea of the movement Fixation/diversification (closed or open skill) Coordination (acquire the pattern) Control (adapt the pattern as needed) Early learning Stiff looking Inaccurate Inconsistent Show, halting Timid Indecisive Rigid Inefficient Many errors Later learning More relaxed More accurate More consistent More fluid More confident More decisive More adaptable More efficient Fewer errors Coach Education Series Copyright © ITF 2009 Automatic Accurate Consistent Fluid Confident Certain Adaptable Efficient Recognises errors Learning and Performance • Performance: The observable behaviour of a player • Learning: Internal phenomenon that can only be inferred from the player's performance Coach Education Series Copyright © ITF 2009 Learning and Performance • Performance changes during learning: – Performance of a skill should show improvement over time – Performance should become increasingly more consistent – Increases in certainty – Decreases in energy expenditure – Sometimes decreases in movement time Coach Education Series Copyright © ITF 2009 How to assess learning: Performance measures • Response outcome: – – – – Errors Time to complete, reaction time Distance Trials to completion • Response production: – Kinematics: displacement, velocity, acceleration, joint angle – EMG: muscle activity Coach Education Series Copyright © ITF 2009 How to assess learning: The example of the serve • Observing during practice: Coach records the number of good serves made by the players during the serve period of the session • Practice tests (retention tests): By using a serve test • Match tests (transfer tests): By charting the serve effectiveness during matches Coach Education Series Copyright © ITF 2009 Assessment measures • Represent observable characteristics of the assessed skill • Are valid indicators of goal achievement • Reflect both the outcome and process • Provide players with meaningful feedback Coach Education Series Copyright © ITF 2009 Control of movement: Motor Programmes • Direct the control of movement • Are abstract representations of the actions • Contain information on an action (order of events, time between events, muscular force to produce the action) that allows a movement to be executed: – Smoothly, efficiently and accurately • Can be modified by sensory feedback Coach Education Series Copyright © ITF 2009 Transfer of learning: definition and types • The gain or the loss of a player’s proficiency on one task as a result of previous practice or experience on another task • Types: – Near transfer: Occurs from one task to another very similar task or setting – Far transfer: Occurs from one task to another very different task or setting Coach Education Series Copyright © ITF 2009 Transfer of learning: how to enhance it • Direct player’s attention to elements of previous learned tasks • Provide opportunities for players to practice tasks that contain elements that are similar to those of the target skill • Allow players to practice the skill in situations which are similar to the playing context Coach Education Series Copyright © ITF 2009
