KS4 OCR GCSE PE - Analysis of Movement

Which of the following is an example of a first class lever in the human body?

• The elbow joint during a bicep curl

• The neck when nodding the head

• The ankle when standing on tiptoes

• The knee during a squat

What is the main advantage of a second class lever?

• Increases speed of movement

• Provides a mechanical advantage to lift heavier loads

• Allows for a greater range of motion

• Reduces the effort needed for fast movements

Which plane divides the body into left and right halves?

• Frontal plane

• Sagittal plane

• Transverse plane

• Coronal plane

Which axis runs from front to back through the body?

• Longitudinal axis

• Transverse axis

• Sagittal axis

• Frontal axis

Which movement occurs in the sagittal plane?

• Abduction of the arm

• Flexion of the knee

• Rotation of the head

• Lateral flexion of the spine

During a star jump, which plane and axis are primarily involved?

• Sagittal plane and transverse axis

• Frontal plane and sagittal axis

• Transverse plane and longitudinal axis

• Frontal plane and frontal axis

Which lever system is used when standing on tiptoes?

• First class lever

• Second class lever

• Third class lever

• Fourth class lever

What is the mechanical disadvantage of a third class lever?

• Cannot move quickly

• Requires more effort to move a load

• Cannot lift heavy loads

• Reduces range of movement

Which joint action is an example of abduction?

• Raising your arm out to the side

• Bending your knee

• Turning your head

• Pointing your toes

Which sporting movement is an example of rotation in the transverse plane?

• Kicking a football

• Performing a pirouette in ballet

• Jumping vertically

• Throwing a javelin
