Muscle contractions and planes of motion

As your bicep pulls weight towards your body the shortening of those bicep muscles is called:

• Concentric contraction

• Eccentric contraction

• Isometric contraction

Lowering the weight during bicep curls lengthens the bicep muscle which is an example of

• Concentric contraction

• Eccentric contraction

• isometric contraction

Movement that decreases the joint angle and is in the sagittal plane.

• Flexion

• Extension

Movement that increases the joint angle and is in the sagittal plane.

• Flexion

• Extension

Movement away from the midline of the body in the frontal plane

• Adduction

• Abduction

Movement towards the midline of the body in the frontal plane

• Adduction

• Abduction

Movement around a central axis in the transverse plane

• Adduction

• Abduction

• Rotation

• Flexion

Exercises that include a side to side motion are in which plane?

• Saggital

• Frontal

• Transverse

Exercises that include a front and back motion are in which plane?

• Sagittal

• Frontal

• Transverse

Exercises that involve a twisting motion are in the

• Sagittal plane

• Frontal Plane

• Transverse Plane
