  1. Individual Differences

  2. Individual Differences • Relatively stable & enduring characteristics unique to individuals • Height, body type, etc. • # of fast twitch muscle fibers • Affect the rate & potential for developing skill proficiency

  3. Motor Abilities • Genetic traits • Cannot be modified thru practice • Prerequisite for skilled performance • Degree to which develop proficiency dependent on if possess necessary underlying abilities

  4. Inherited traits Stable & enduring Few in number Underlie performance of many skills Developed with practice Modifiable Many in number Depend on different subsets Abilities & Skills

  5. Capabilities • Characteristics subject to change as result of practice • Represent potential to excel in performance of task Multilimb Coordination Person A Person B

  6. Categorizing Motor Abilities • 11 Perceptual Motor Abilities • 9 Physical Abilities • All abilities may not yet be identified • Tracking • Eye-Foot Coordination • Dynamic Balance • Static Balance

  7. Perceptual Motor Abilities

  8. Physical Proficiency Abilities

  9. What do you think? • Can an individual have abilities but not be skilled? • Can an individual be skilled without ability?

  10. Practical Application • Expect to see differences in patterns of people’s abilities • Individual pattern will facilitate better performance on some tasks rather than others • Ability pattern only one factor contributing to performance

  11. Underlying Abilities - Volleyball Spike • Control Precision • Multi-limb Coord. • Rate Control • Aiming • Explosive Strength • Trunk Strength • Dynamic Flexibility

  12. Skill Subsets

  13. Task Analysis • Choose a skill • Perform task analysis • Determine underlying abilities required to achieve high degree proficiency

  14. Perceptual Motor Abilities • Multilimb coordination • Control precision • Response orientation • Reaction time • Speed of arm movement • Rate control • Manual dexterity • Finger dexterity • Arm-hand steadiness • Wrist/finger speed • Aiming

  15. Physical Proficiency Abilities • Static strength • Dynamic strength • Explosive strength • Trunk strength • Extent flexibility • Dynamic flexibility • Gross body coordination • Stamina

  16. Predicting Future Performance • Possible? • Problems?
