Harman et al developed equations for predicting the peak and average power output during a vertical jump. These correct some of the problems seen with the Lewis formula (above). The authors are from the US Army Research Institute of Environmental Medicine (Natick, Massachusetts), Boston University, and Pennsylvania State University.
Parameters:
(1) vertical jump height in centimeters
(2) body mass in kilograms
peak power in watts =
= (61.9 * (vertical jump height in cm)) + (36 * (body mass in kilograms)) + 1822
average power in watts =
= (21.2 * (vertical jump height in cm)) + (23 * (body mass in kilograms)) - 1393
NOTE: In Table 2, the peak jumping power was 3,767 W with the average 1,325 W. When the above formula is used as written, values nearer 7,500 Watts are generated for the peak values. If the (+1,822) is replaced by (-1,822) then values for peak power seem more reasonable.
