1.  Hockey Slap Shot By Brandon Starkey and Tyler Kohmetscher

2. Equipment  The hockey stick is usually between five and six feet long.  Made of wood, aluminum, fiber glass, carbon fiber, kevlar, and titanium.  They weigh between a pound and a pound and a half depending on material.

3. Phases of the Shot  Preparation  Windup  Downswing  Loading the stick  Impact  The follow through

4. Preparation Phase  Line front foot up with puck  This location optimizes energy to transferred to puck  Lead shoulder pointed to the target

5. Wind Up Phase  Draw stick back  Further back=more velocity, but also means more time

6. Downswing  Rotate hips, trunk, and shoulders  Contact anywhere from 4-12 inches behind the puck  Contacting behind the puck is essential for bend of the stick

7. Loading the Stick  Apply pressure to the Stick by putting downward pressure on the stick with the lower hand  The height of the lower hand on the shaft is critical.  too high=not enough bend in stick  too low=not as much energy will be transferred to the puck

8. Impact  Point when the blade catches the puck  Strike the heel of the blade (sweet spot)  Further out= more torque, not as accurate

9. Follow Through  Used to maintain balance

10. Keys to the Shot  Blade orientation  Hand Position  Impulse Duration  Stick Bending  “The key to a good slap shot is the conversion of angular momentum to linear momentum.”

11. Muscles Used  Shoulder Adduction  Pectoralis Major  Latissimus Dorsi  Teres Major  Shoulder Flexion  Anterior Deltoid  Shoulder Internal Rotation  Pectoralis Major  Subscapularis

12. Muscles Used (cont)  Trunk Rotation  Internal/External obliques  Hip Flexion  Psoas  Illiacus  Pectineus  Elbow Extension  Triceps Brachii

13. Muscles Used (cont)  Forearm Pronation  Pronator Quadratus  Wrist Flexion  Flexor carpi radialis  Ulnaris
