Question

Landing:

Sub phases-
Active:
What occurs during this?

a) Flexion of the knees and hips, absorbing impact forces, maintaining balance.
b) Extension of the knees and hips, generating propulsion, taking off for the next jump.
c) Hyperextension of the spine, avoiding impact forces, achieving maximum height.
d) Lateral movement, reducing balance, increasing risk of injury.

Answer 1

Option (A), During the active sub-phase of landing, flexion of the knees and hips occurs to absorb impact forces and maintain balance. Landing mechanics are crucial for preventing injuries, as the body experiences significant forces upon impact.

Step-by-step explanation:

The active sub-phase of landing primarily involves flexion of the knees and hips, which is critical for absorbing the impact forces and maintaining balance upon hitting the ground. Incorrect landing mechanics, such as landing stiff-legged, can result in immense forces that lead to potential injuries, like fractures. The natural structures of the body, including the arches of the foot, play a significant role in absorbing and distributing these forces, which can amount to 2.5 times your body weight when running. The nervous system also coordinates muscle actions to ensure that landings are not only safe but also efficient for subsequent movements, as is necessary in activities like a high jump or a standing broad jump.
