Answer Details
The physical fitness component that is necessary for a high jumper is "flexibility". High jump requires the athlete to be able to bend and stretch their body in order to clear the bar successfully. A high level of flexibility allows the athlete to achieve the necessary body positions during the jump, such as the "Fosbury Flop" technique, which requires the athlete to arch their back and rotate their hips while clearing the bar. Without sufficient flexibility, the athlete may struggle to achieve the correct body positions and may not be able to jump as high.
