Peak Power (Sayers) vs Vertical Jump Height
Formula
## Vertical Jump Power Estimation The vertical jump is a standard test of lower-body explosive power. The Sayers equation converts jump height and body mass into peak power. ### Sayers Equation **Peak Power (W) = 60.7 x Jump Height (cm) + 45.3 x Body Mass (kg) - 2055** This regression equation was developed by Sayers et al. (1999) and validated against force plate measurements. It is one of the most widely used field-test power equations in sports science.
Exemplo Resolvido
An 80 kg athlete with a 55 cm vertical jump.
- 01Peak power = 60.7 x 55 + 45.3 x 80 - 2055
- 02= 3,338.5 + 3,624 - 2,055
- 03= 4,907.5 W (approximately 4,908 W)
- 04Power per kg = 4,908 / 80 = 61.3 W/kg
- 05Jump height = 55 / 2.54 = 21.7 inches
Perguntas Frequentes
What is a good vertical jump?
Average male: 40-50 cm (16-20 in). College athletes: 55-70 cm (22-28 in). Elite NBA players: 75-100+ cm (30-40+ in).
How accurate is the Sayers equation?
It correlates with force plate data at r = 0.88-0.93. It is more accurate than the older Lewis formula but less precise than direct force plate measurement.
Does the vertical jump predict athletic ability?
It strongly correlates with sprint speed, agility, and sport-specific power. It is used in the NFL Combine, NBA Draft Combine, and many sport talent identification programs.
