A long jumper lands in the sand pit after their jump. To minimise injury risk, the most important biomechanical principle they should apply is:

Landing with straight legs to transfer force quickly through the body
Using joint flexion to absorb and dissipate landing forces gradually
Landing on their heels to maximise contact surface area
Keeping their arms rigid to maintain balance during landing

\(B\)

Show Worked Solution

B is correct: Joint flexion allows gradual force absorption through muscle lengthening, reducing injury risk to joints and surrounding tissues.

Other Options:

A is incorrect: Straight leg landing prevents force absorption and increases injury risk.
C is incorrect: Heel landing creates impact forces; controlled foot placement is more important.
D is incorrect: Rigid arms prevent effective force absorption and balance adjustment.
