6 cze 2022 · We take a look at a force plate analysis of a vertical jump and explain the five phases of a vertical with charts and interactive calculators.
High-Speed Camera – When using a high-speed video camera and appropriate software, flight time is typically calculated via slow-motion analysis. From this, because the flight time has been obtained, jump height can then be calculated using the formulas above.
Of the three methods of calculating the flight height presented here, the flight time method is the simplest to perform.8 However, the flight time method usually overestimates the true flight height because the height of the jumper’s c.m. at landing is lower than that at takeoff.
In force plate technology, the jump height is most commonly calculated using the flight time (FT) or the takeoff velocity (TOV), which provide only the distance traveled in the air and neglect...
The figure below shows a force time curve from a countermovement jump (CMJ) - force is on the Y (vertical) axis and time is on the X (horizontal) axis. When you move on the plates, changes in the pattern and magnitude of the force applied to the plates reflect your performance.
The height of the jump may be calculated by these methods (Linthorne 2001): From the flight time of the jump. By applying the impulse–momentum theorem to the force–time curve, and. By applying the work–energy theorem to the force-displacement curve.
Vertical Jump Measurement Using Force Plates. Objectives. To apply Newton's second law. To understand the forces involved during counter movement jump and squat jump. To calculate the flight height of a jump from the time of flight. Background: Vertical Jump. The vertical jump is an essential motor skill in many sports.
