16
Q

What are antagonistic pairs

A

As one muscle contracts (shortens) the other relaxes (lengthens), the muscles contracting is called the agonist or the prime mover. The relaxing muscle is called the antagonist

17
Q

What is isometric contractions

A

When muscle length remains relatively constant

18
Q

What is an eccentric contraction

A

Is the lengthening of a muscle- relaxation

19
Q

What is a concentric contraction

A

The shortening of a muscle- contraction

20
Q

Antagonistic pairs: biceps and triceps

A

-Flexion of the arm at the elbow (upward phase of bicep curl, the bicep is the agonist and the tricep is the antagonist as it is relaxing to allow the bicep to contract
- extension of the arm at the elbow (straightening arms in chest press)- biceps is the antagonist and triceps is the agonist. The bicep is relaxing to allow the triceps to contract

21
Q

what is the sagittal plane

A

a vertical plane, which divides the body into right and left parts
- goes with transverse axis
- extension, flexion, plantar flexion, dors- flexion, hyper-extension

22
Q

what is the frontal plane

A

a vertical plane that divides the body into front and back halves
- goes with sagittal axis
- abduction, adduction

23
Q

what is the transverse plane

A

divides the body into upper and lower halves
- goes with longitudinal axis
- rotation, horizontal abduction, horizontal adduction

24
Q

what is transverse axis

A

runs from side to side across the body

25
Q

what is sagittal axis

A

runs from front to back

26
Q

what is longitudinal axis

A

runs from top to bottom

27
Q

examples of the sagittal plane about a transverse axis

A

kicking football
chest pass in netball
walking
jumping
squatting

28
Q

examples of the frontal plane about a sagittal axis

A

cartwheel

29
Q

examples of the transverse plane about a longitudinal axis

A

360 twist
spin
discuss thrower rotating

30
Q

what is an agonist

A

the prime mover
responsible for the movement occuring

31
Q

what is the antagonist

A

muscle that works in opposition to the agnosit

32
Q

main agonist and antagonist for joint actions

A

joint action-agonist-antagonist
elbow flexion-biceps-triceps
elbow extension-triceps-biceps
ankle plantar flexion-gastrocnemius-tibialis anterior
ankle dorsiflexion-tibialis anterior-gastrocnemius
knee extension-quadriceps-hamstrings
knee flexion-hamstrings-quadriceps
hip flexion-iliopsoas/hip flexors-gluteals
hip extension/hyper extension-gluteals-hip flexors
hip adduction & horizontal-adductors-tensor fascia latae and gluteus medius
hip abduction & horizontal-tensor fascia latae and gluteus medius- adductors
shoulder flexion-anterior deltoid-latissimus dorsi
shoulder extension-latissimus dorsi- anterior deltoid
shoulder horizontal abduction-latissimus dorsi-pectorals
shoulder horizontal adduction-pectorals-latissimus dorsi
shoulder adduction-posterior deltoid-middle deltoid
shoulder abduction-middle deltoid-posterior deltoid
