Basic Kinesiology

1. Basic Kinesiology Kinesiology-the study of movement Brings together anatomy, physiology, physics, and geometry as they relate to the human bodies movement.

2. Basic Kinesiology • Biomechanics-mechanical principles that relate directly to the human body. • Can be relative to the extremities or an implement such as a bat or racket • Can be static(nonmoving) or dynamic(moving) activities. • Read paragraph 3-4 on page 3 and paragraph 1-2 on page 4

3. Basic Kinesiology • Anatomical Position-human body standing upright, eyes forward feet parallel, arms at side, and hands with palms facing forward.

4. Basic Kinesiology-types of motion • Linear Motion- a straight line from one point to another. • Rectilinear Motion-straight line like a player running across a field. • Curvilinear Motion- straight line but in a curved path, like a diver leaving the diving board.

5. Basic Kinesiology-types of motion • Angular Motion- Rotary motion is when all the parts of the object move through the same angle, same direction at the same time, but do not move the same distance. • When you flex your elbow your hand and wrist travel a different distance through space.

6. Basic Kinesiology-types of motion • Generally speaking most movement within the body is angular, most movement outside the body is linear. • Get into groups of 4 and create a list(use pg 6): • 2 linear movements • 2 angular movements • 2 combination movements

7. Joint Movements • Arthrokinematics: relationship of joint surface movement. The humeral head’s movement within glenoid fossa of scapula. • Osteokinematics: relationship of the movement of bones around a joint axis. Humerus moving on scapula

8. Kinesiology • Movements of Synovial Joints (freely moving jts. where most joint motion occurs) • Flexion-decrease angle between 2 bones • Extension-increase angle between 2 bones • Hyperextension-increase angle between 2 bones beyond the normal range of motion (ROM).

9. Kinesiology • Movements of Synovial Joints • Abduction-Limbs only-limb moves away from the midline of the body. • Adduction-Limbs only-limb moves toward the midline of the body. • Rotation-when a bone turns on its axis towards or away from the midline of the body

10. Movements of Synovial Joints • Circumduction- the ability of a limb to move in a circular path around an axis. • Supination- moving into a supine position. • Pronation- moving into a prone position. • Plantarflexion- pointing toes down, “planting the foot” • Dorsiflexion- bringing the toes up • Palmarflexion – flexing the wrist

11. Kinesiology • Movements of Synovial Joints • Plantarflexion- pointing toes down, “planting the foot” • Dorsiflexion- bringing the toes up

12. Kinesiology • Movements of Synovial Joints • Inversion- turns the sole of the foot inward, medially. • Eversion- turns the sole of the foot outward, laterally. • Protraction- occurs in the transverse plane, moving the body part forward • Retraction- occurs in the transverse plane, moving the body part backward

13. Kinesiology • Movements of Synovial Joints • Shoulder Abduction – movement of the arm away from the body • Shoulder Adduction - movement of the arm toward the body • Shoulder Horizontal Abduction – • Shoulder Horizontal Adduction • Radial Deviation • Ulnar deviation

14. Kinesiology Basics • Medial-Middle/Midline • Lateral-outside

15. Kinesiology Basics • Distal- far from midline • Proximal- close to midline

16. Kinesiology Basics • Superior- above another structure • Inferior- below another structure

17. Kinesiology Basics • Front =anterior =ventral • Back =posterior =dorsal
