1: What is”kinesiology?”

The study of human biomechanics

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 direction of force/load
Isometric: muscle length remains constant, no movement occurs in relation to force/load

4: Fill in the chart below

5: What is the”prime mover?”

The working muscle or agonist. the muscle 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 which provides 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
