Which of the following is an example of a first-class lever in the human body?
Why might biomechanists emphasize the preparation phase in elite sprinting performance?
In a long jump, why are the final preparatory steps immediately before take-off particularly important?
In the preparation–execution–recovery model of skill phases, a long jumper’s run-up is primarily part of which phase?
Which of the following best describes the recovery phase in a sprint start?
The elbow joint during bicep curls
The neck, when tilting the head backward
The ankle joint during calf raises
The knee joint during a leg extension
It positions the body to generate optimal ground reaction force and acceleration at the start
Errors here cannot be corrected later in the movement
It establishes appropriate joint alignment and muscle pre-tension to improve subsequent force production
It helps optimize body position to reduce braking forces and improve running efficiency in the drive phase
They position the body for an effective take-off while maintaining approach speed.
They allow the athlete to generate maximum velocity before take-off.
They provide recovery time to avoid injury.
They reduce energy expenditure for later jumps.
