2: What is the correlation between kinesiology and biomechanics?

Biomechanics is the scientific system of human movement patterns and adaptations via the musculoskeletal system; kinesiology is the scientific study of these patterns and adaptations and the structures that govern them.

3: Name and describe the 3 types of muscular contractions:

Concentric: muscle length shortens and movement occurs in opposition to force/load
Eccentric: muscle length increases, and movement occurs in the direction of force/load
Isometric: muscle length remains constant, and no movement occurs about force/load

4: Fill in the chart below

5: What is the”prime mover?”

The working muscle or agonist. The muscle is undergoing contraction.

6: What is the “assistant mover?”

Plays a secondary/support role to the prime mover

7: What is the connection between agonist and antagonist?

As the agonist contracts, the antagonist relaxes

8: What does “stabilizer muscle” mean, and give an example of its use in an exercise?

Stabilizer muscles stabilize the body or body parts through multi-plane movements

9: What is synergy in correlation to muscles?

Synergy is performed by a synergist muscle, providing joint stability for effective agonist action.

10: Name and describe the 4 types of muscular movement

  • Isometric: muscle length remains constant and maintains tension
  • Isotonic: muscle length changes and maintains tension
  • Concentric: muscle length decreases in resistance to force
  • Eccentric: muscle length increases and is overcome by force

11: Describe the 3 imaginary planes of motion and give an exercise executable in each

  • Sagital: passes to and from the front and back
  • Frontal: divides front and back
  • Transverse: divides top from bottom.

12: Name and describe the 6 primary movements that transpire in the human body
