1. EDU4SBM Sports Biomechanics 1 Lecture Week 8 Analysing Sports Technique

2. EDU4SBM Sports Biomechanics 2 Analysing performance and correcting errors

3. EDU4SBM Sports Biomechanics 3 1. Determine the objectives of the skill 100m -Speed Discus - accuracy and distance High jump Volleyball strike Drop punt

4. EDU4SBM Sports Biomechanics 4 2. Note any Special characteristics Repetitive skills -Running, swimming Non repetitive skills -shot put Predictable environments -weightlifting (closed skills) Unpredictable environments -surfing (open skills)

5. EDU4SBM Sports Biomechanics 5 3. Study top flight performances The techniques that top athletes use to perform a skill all show common features

6. EDU4SBM Sports Biomechanics 6 4. Divide the skill into phases. Preparatory movements Windup (backswing) Force producing movements Follow through (or recovery)

7. EDU4SBM Sports Biomechanics 7 5. Divide each phase into key objectives. eg: force producing phase of golf swing -shift body weight from rear to front foot -rotate hips into drive -extend arms when club contacts ball

8. EDU4SBM Sports Biomechanics 8 6. Understand the mechanical reason each key element is performed. Golf – why cock and uncock wrists in golf ? Swimming - direction of freestyle swimmers pull ? Javelin -why rotate hips in javelin ?
