NATURE of SKILLS

NATURE of SKILLS. Pattern - run, jump, throw, push, strike, kick lift, push Skill - pattern adapted to a task (e.g. HJ, Clean) Technique - variations of a skill (e.g. VB serve) Style - unique timing or specialized moves Constraints - limits (e.g. person, rules, equipment).

Presentation Transcript

  1. NATURE of SKILLS • Pattern - run, jump, throw, push, strike, kick lift, push • Skill - pattern adapted to a task (e.g. HJ, Clean) • Technique - variations of a skill (e.g. VB serve) • Style - unique timing or specialized moves • Constraints - limits (e.g. person, rules, equipment)

  2. CLASSIFICATION of SKILLS • CLOSED - predictable environment - adhere to ideal biomechanical principles • OPEN - unpredictable, execution often less than ideal • DISCRETE - definite beginning & end • CONTINUOUS - run,swim,row,bike,skate

  3. SKILL PHASES • P • E • F / R

  4. Horizontal Distance Vertical Distance Project for Accuracy Accuracy with Speed Manipulate Resistance Timed over a Distance Ideal/Model Pattern Interact with Elements Overall Performance Objective: OPO

  5. OPO: Project for Max DistanceHORZ

  6. OPO: Project for Max DistanceVERT

  7. OPO:Project forAccuracy

  8. OPO:Accuracywith Speed

  9. OPO: Manipulate a Resistance

  10. OPO: Move Over a Timed Distance

  11. Move Body in an Ideal or Model Pattern

  12. OPO: Interact with the Environment

  13. Examples of Biomechanical Principles • Factors Affecting Muscle Force (e.g. length/tension) • Momentum (linear and angular) • Radius (v = r) • Kinetic Link (Throw and Push Patterns) • Lift and Drag (e.g. Airfoil Shapes, Magnus Effect) •  of Projection, Attack, and Attitude • Rebound and Spin • Methods of Initiating Body Rotations

  14. ANALYSIS PROCESS • Discrete Parts • Mechanical Purpose of each Part • Biomechanical Factors • Biomechanical Principles to achieve BF • Critical Features(i.e. observable body movements)
