Presentation Transcript

  1. Testing Item I ― Centre Shot (墊步射球) Player A Player B

  2. How to analyse movement

  3. Player A & B Centre Shot Displacement-time Graph Player B Player A

  4. Player A & B Centre Shot Velocity-time Graph Player B Player A

  5. Findings (I) • Compared with the centre shot, the ball velocity of player B is faster than that of player A. Why? • The arm flailing action of player B is better than that of player A. • Room for improvement in arm flailing action of player A.

  6. How to analyse movement

  7. Testing Item II ― Player A with different shots Centre Shot Penalty Shot

  8. Player A different shots Displacement-time Graph Penalty Shot Centre Shot

  9. Player A different shots Velocity-time Graph Centre Shot Penalty Shot

  10. Findings (II) • Compared with the penalty shot, the ball velocity of centre shot is more or less the same as that of penalty shot. Why? • The initial body movement of player A is ineffective to increase the initial ball velocity. • Player A has to improve his initial body movement.
