2. Phases

4. Muscles Involved in Lower Extremity QUADRICEPS GROUP • Rectus femoris • Vastusmedialis • Vastuslateralis • VastusIntermedius • LOWER LEG • Gastrocnemius • Soleus • Tibialis anterior

5. Muscles Involved in Lower Extremity HAMSTRINGS GROUP • Biceps femoris • Semitendinosus • Semimembranosus

6. Muscles involved in upper extremity • SHOULDER JOINT & GIRDLE • Trapezius • Rhomboids • Serratus anterior • Pectoralis minor • Deltoid • Coracobrachialis • Subscapularis • Infraspinatus • Teres minor • Supraspinatus

7. Muscles involved in upper extremity • ELBOW JOINT • Biceps brachii • Brachialis • Brachioradialis • Triceps brachii

8. Muscles involved in upper extremity • WRIST JOINT • Extensor carpi radialisbrevis & longus • Extensor carpi ulnaris • Extensor pollicislongus • Flexor carpi radialis • Flexor carpi ulnaris • Flexor digitorumsuperficialis • & profundus • Pronator teres • Supinator

9. Preparatory phase

10. Preparatory: lower extremity chart

11. Preparatory: shoulder girdle chart dominant & non-dominant • Other muscles involved in isometric contraction: • Supraspinatus • Infraspinatus • Teres minor • Subscapularis • Levator scapulae • Trapezius • Rhomboids

12. Preparatory: Shoulder joint chart dominant & Non-dominant

13. Preparatory: elbow & wrist joint dominant & non-dominant

14. Preparatory: wrist joint action on dominant side

15. Execution phase

16. Execution phase: lower extremity dominant & non-dominant

17. Execution phase: shoulder girdle dominant & non-dominant

18. Execution phase: shoulder joint dominant & non-dominant NON-DOMINANT

19. Execution phase: elbow Joint dominant & non-dominant WRIST JOINT DOMINANT NON-DOMINANT

20. Follow through

21. Follow through phase: Lower extremity dominant & non-dominant **Positionof the hip & knee in the follow through are the same as in execution phase, however they are now isometrically contracting.

22. Follow through phase: Shoulder Joint & girdle dominant & non-dominant • **See shoulder joint & girdle slides of execution phase. There is no change in joint movement going into follow through. ELBOW JOINT DOMINANT & NON-DOMINANT **Reference elbow joint slide of execution phase for follow through as well. There is just further extension of the dominant elbow joint.

23. Follow through phase: wrist joint DOMINANT NON-DOMINANT

24. MOST COMMON PATHOLOGIES OCCURING FROM FREE THROW • 3 very closely related pathologies: • Shoulder Impingement- space between acromion & rotator cuff tendons is narrowed when arm is raised, causing the tendons to be pinched or impinged. • Rotator Cuff Tendonitis- tendons become irritated or rubbed from repetitive lifting or overhead use. • Bursitis- bursa becomes inflamed, which causes it to swell and fill with more fluid (usually accompanies rotator cuff tendonitis)

25. symptoms • Sudden pain and stiffness when arm is lifted • May also have pain when arm is lowered from elevated position • Radiating pain from front of shoulder to side of arm • Pain at night • Loss of strength & motion • Difficulty with motions behind the back such as buttoning or zipping.

26. Treatment: Considering patient age, activity level, & general health • Before resorting to surgery, a physician may prescribe: • Rest • Non-steroidal anti-inflammatory medication • Physical therapy • Cortisone injection • If none of these are effective, the patient and orthopedist may decide on arthroscopy. • (Pictured to the right)

27. Exercises Dumbbell front raises Dumbbell lateral raises Back squats Tricep extensions

28. Exercises (cont’d) • Most importantly….. • The Donkey Calf Raises And pictured to the right is Arnie repping out some donkey calf raises with a pal.
