Jump power calculator: the Sayers equation
Enter the jump height and the day's body mass. Peak power comes from the Sayers equation; relative power divides it by body mass.
The formula
Estimated peak power = 60.7 × jump height (cm) + 45.3 × body mass (kg) − 2055
Estimated relative peak power = peak power ÷ body mass (kg)
Sayers, Harackiewicz, Harman, Frykman & Rosenstein (1999), Medicine & Science in Sports & Exercise 31(4):572-577. The equation estimates; it is not a clinical report and does not replace a direct measurement. It is the same calculation StatsCenter applies when a club collects.
