Sample Answer
Force absorption
- Quadriceps, hamstrings and calf muscles contract eccentrically during landing.
- This controlled lengthening prevents sudden joint compression and distributes forces.
Joint flexion
- Ankles, knees and hips bend simultaneously upon ground contact.
- This flexion increases absorption time and transforms peak forces into manageable loads.
Base of support
- Feet positioned shoulder-width apart provide lateral stability during landing.
- This wider stance prevents sideways falling and enables balanced force distribution through both legs.
Centre of gravity
- Deep knee bend lowers the body’s centre of gravity toward ground.
- Athletes maintain better equilibrium when mass is positioned lower.
- Positioning the body in this way enhances balance control reducing fall risk.
