Question

Vertical Jump:

Mechanical energy transfer- During takeoff, hip and knee extending
What is caused at the hip and knee? Does the net muscle length change much? What does this allow two-joint muscles to do?
a) Tension
b) Compression
c) Lateral movement
d) Flexibility

Answer 1

During takeoff in a vertical jump, the hip and knee extend, causing a change in the net muscle length. This allows two-joint muscles to generate tension and facilitate movement.

Step-by-step explanation:

During takeoff, both the hip and knee extend, causing a change in the net muscle length. This change in the muscle length allows two-joint muscles to perform certain actions, such as generating tension and facilitating movement.
