1

what is the upper shoulder?

trapezius

2

what is the name of the shoulder muscle?

deltoid

3

what is the name of the chest muscle?

pectoralis major

4

what is the name of the back mid upper arm muscle?

tricep

5

what is the name of the front mid upper arm muscle?

bicep

6

what is the name of the stomach muscle?

abdominal muscles

7

what is the name of the muscle in the front rib area?

external obliques

8

what is the name of the back rib area muscle?

latissimus dorsi

9

what is the name of the hip muscle?

hip flexors

10

what is the name of the bottom muscle?

gluteus maximus

11

what is the name of the front upper leg muscle?

quadriceps

12

what is the name of the back upper leg muscle?

hamstrings

13

what is the name of the shin muscle?

tibialis anterior

14

what is the name of the calf muscle?

gastrocnemius

15

what is the function of the deltoid?

Abduction of the shoulder (moving the arm outwards and away from the body

16

what is the function of the Pectoralis major?

Adduction of the shoulder (moving the arm towards the body); Shoulder horizontal flexion (moving the arms forwards in front of the body)

17

what is the function of the Triceps?

Extend the elbow (straightening the arm)

18

what is the function of the Biceps?

Flex the elbow (bending the arm)

19

what is the function of the External obliques?

Trunk rotation (turning the body sideways

20

what is the function of the Latissimus dorsi?

Shoulder adduction (moving the arm towards the body); Shoulder horizontal extension

21

what is the function of the Hip flexors?

Hip flexion (moving knee up towards the chest)

22

what is the function of the Gluteus maximus?

Hip extension (moving the leg backwards)

23

what is the function of the Quadriceps?

Extend the knee (straightening the leg)

24

what is the function of the Hamstrings?

Flex the knee (bending the leg)

25

what is the function of the Gastrocnemius?

Plantar flexion of the ankle (pointing the toes downwards)

26

what is the function of the Tibialis anterior?

Dorsiflexion of the ankle (bringing the toes up towards the shin)

27

what is an Isotonic concentric contraction?

this involves the muscle shortening. The origin and insertion of the muscle move closer together and the muscle becomes fatter.

28

what is an Isotonic eccentric contraction?

this involves the muscle lengthening whilst it is under tension. The origin and the insertion move further away from each other. An eccentric contraction provides the control of a movement on the downward phase and it works to resist the force of gravity.

29

what is an Isometric contraction ?

this involves a muscle producing tension but staying the same length. This occurs when the body is fixed in one position.

30

what are the antagonistic pairs?

Biceps and Triceps


Hamstrings and Quadriceps


Gluteus maximus and Hip flexors


Gastrocnemius and Tibialis anterior


Pectoralis major and Latissimus dorsi
