Answer 6

Concentric and eccentric

Question 7

Concentric muscle contraction

Answer 7

The normal contraction

When a muscle shortens Under tension

For example the upwards phase of a squat

Question 8

Eccentric

Answer 8

Question 13

Abduction

Answer 13

Moving away from the midline of the body

Question 14

Addiction

Answer 14

Movement towards the midline of the body

Question 15

Horizontal adduction

Answer 15

Movement of the joint from abduction and flexion

Question 16

Horizontal abduction

Answer 16

Movement of the joint from flexion to abduction

Question 17

Sagittal plane/ transverse axis

Answer 17

Movements that take place in the sagittal plane and around the transverse axis are flexion and extension

Eg a swing in tennis

Question 18

Frontal plane and sagittal axis

Answer 18

Movements that take place in the frontal plane and around the sagittal access abduction and abduction

For example a star jump
