$326.91. The Vertec Jump test is a measure of vertical jump height which uses the Vertec device to measure performance. Plyometric exercise uses the stretch-shorten cycle to train muscles to do more work in less time (Holcomb, Lander, Rutland, & Wilson, 1996; Komi, 1978). One plate can get the gross height of a jump or isometric pull, but two plates can reveal asymmetry problems or improvements. Using a force plate for jump performance analysis is a well accepted and proven method (1). Analysis of standing vertical jumps using a force platform Nicholas P. Linthornea) ... electrical output that is proportional to the force on the plate. And it is comparable price to a Vertec, but this is much easier to do sports teams when you have 8 minutes to get 15 kids through vertical jump tests during fitness testing and adds some other training versatility. Pressure plates can get contact times and estimated flight duration to calculate what an athlete is likely doing, but only a force plate can’t be cheated or gamed. This period was chosen , as all subjects were able to produce a flight phase greater than 0.3 sec. Instead of looking at vertical jump height, we instead used our Neulog force plates to examine whether the amount of force produced when doing a counter-movement jump (CMJ) was correlated to throwing velocity.. Vertical Jump Lab 2 PROCEDURE Go to one of the University computers and log on to the computer in the usual way.
NEULOG Force Plate Logger Sensor, 16 bit ADC Resolution ... Tandem Sport Vertical Challenger - Stand-Alone Jump Measurement Tester Training Aid 4.0 out of 5 stars 44. Outside of sensor type, the next decision is to choose between a single plate and dual force plates. the jump with the force platform unloaded (peak difference between the vertical force trace and 0 N). The common and appropriate use of force plates is an attempt to gauge how power from training and subsequent rest interacts with individual athletes with primarily jump testing in the vertical plane. A complete force plate system consists of the force plate:Optima-HPS, Optima-BMS, or Optima-SPS, an amplifier, a computer or data acquisition system, mounting hardware, interconnecting cables, and AMTI’s data acquisition software. You may be surprised to know that TOUR players create a tremendous amount of push from the ground during the swing and have a vertical jump test average of 20”. The homemade force plate.
As Greg explains, the same power in a vertical jump for a rebound is also a key source of power in the golf swing—vertical thrust. One of the most often used parameters is the jump height s which is calculated using a "traditional" double integration of the vertical force F: acceleration a(t) = F(t) / m velocity v(t) = ∫ (a(t) – a0) dt jump height s(t) = ∫ (v(t) - v0) dt
What a force plate does not take into equation are all the variables in a vertical jump of the human body (and body parts). A force plate, whether one or dual, is the most comprehensive way to evaluate a jump and is the gold standard in research. Throughout this summer we wanted to investigate the relationship between vertical jump force production and throwing velocity. A force plate is one method for measuring vertical jump height. Measuring Vertical Jump using a Force Plate. Parameters That Influence Vertical Jump Height. A thin sheet of rubber was glued to the outer surfaces of both plates to prevent slipping. And at $500 it is a lot cheaper than $20,000 for force plate that correlates between 0.90-0.95 with this timing pad. The test is extremely practical as it uses a simple device which is portable and can be used in a variety of settings to measure performance. It is usually reserved for use in scientific research.
The vertical force shows a characteristic double hump, which results from an upward acceleration of the center of gravity during early stance, a reduction in downward force as the body ‘flies’ over the leg in mid-stance and a second peak due to deceleration, as the downward motion is checked in late stance.

The research on the relationship between vertical jump … Example: a Kistler Force plate is used for the vertical jump measurement at the NHL combine. If using a force plate, it is better to use jump height based on ground reaction forces as this has been suggested to provide a more valid RSI measure.
