Movement Analysis

Question 1

Levers

Answer 1

FLE 123:

Question 2

Class 1 Lever Example

Answer 2

Lifting the head to head the ball in football
Effort - neck muscles
Fulcrum - neck
Load - head

Question 3

Class 2 Lever Example

Answer 3

Standing on tiptoes/planter flexion of the ankle e.g. when jumping
Fulcrum - Toes/Ball of your foot
Load - Body weight
Effort - Gastrocnemius muscle

Question 4

Class 3 Lever Example

Answer 4

Upward phase of the bicep curl:
Fulcrum - Elbow joint
Effort - Biceps
Load - Weight of arm/weight being held in hand

Question 5

Mechanic Advantage

Answer 5

2nd class levers has mechanical advantage due to the effort arm being longer than the load arm.

It allows you to move a large load with a smaller effort

MA = Load ÷ Effort

Eg
Load = 500N
Effort = 100N
MA = 500 ÷ 100 = 5

Question 6

Planes of Movement

Answer 6

Sagittal, Frontal and Transverse

Question 7

Saggital Plane of Movement definition and example

Answer 7

Vertically splits the body into left and right e.g. arm and leg action during running

Question 8

Frontal Plane of Movement definition and example

Answer 8

Vertically splits the body into front and back e.g. shoulder and hip abduction in the outward phase of a star jump

Question 9

Transverse Plane of Movement definition and example

Answer 9

Horizontally splits the body into upper and lower parts e.g. rotating to play a forehand shot in tennis

Question 10

Axis of Rotation

Answer 10

Longitudinal, Frontal and Transverse

Question 11

Longitudinal Axis of Rotation definition and example

Answer 11

Vertical axis from top to bottom of the body e.g. a dancer performing a spin

Question 12

Frontal Axis of Rotation definition and example

Answer 12

Horizontal axis from the front to the back of the body e.g. a gymnast performing and cartwheel

Question 13

Transverse Axis of Rotation definition and example

Answer 13

Horizontal axis running from side to side e.g. a trampoline performing doing a somersault
