PAPw) from the vertical jump.I have also come across this formula for calculating power from vertical jump height. It is sometimes useful to convert the vertical jump height to units of power.

First, both studies used separate tests to determine vertical jump height and peak power instead of pairing these two variables from the same jump. For immediate assistance, contact Customer Service: The reliance of SSC was determined using the eccentric utilization ratio (EUR), which is derived from the difference between SJ and CMJ and was determined under both conditions. While recent research demonstrates that this equation typically underestimates peak power, the important thing for me is reproducibility (not complete accuracy). may email you for journal alerts and information, but is committed 0000013212 00000 n Tape measure 3. 0000008264 00000 n Give a mechanical explanation for how the sand "cushions" the landing of the jumper. 0000111055 00000 n Please try again soon. vertical jump (method TOV+s). Here is the magic equation: PAPw (Watts) = 60.7 x jump height (cm) + 45.3 x body mass (kg) – 2055 For those who track their data and keep it in some sort of format (usually excel), the determination of peak power in watts is the addition of one cell, but the information it gives you is priceless. Anthropometric and vertical jump ground reaction forces were collected from 460 male volunteers (age: 12 24 years). Subjects performed a single session of measurements on a force platform, where the actual values of peak power (PP), vertical jump height (VJH) and body mass (BM) were recorded during a countermovement

The purpose of this study was to develop and validate a regression equation to estimate peak power (PP) using a large sample of athletic youths and young adults. 0000053344 00000 n Power cannot be calculated (Power = Work ÷ Time) since the Time the force is acted on the body is unknown. 0000109807 00000 n 0000002384 00000 n This test provides a means to monitor the effect of training on the athlete's physical development.The following references provide additional information on this topic:If you quote information from this page in your work, then the reference for this page is:The following Sports Coach pages provide additional information on this topic:
