PEAK VERTICAL JUMP POWER ESTIMATIONS IN YOUTHS AND YOUNG ADULTS

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. Anthropometric and vertical jump ground reaction forces were collected from 460 male volunteers (age: 12�24 years). Of these 460 volunteers, a stratified random sample of 45 subjects representing 3 different age groups (12�15 years [n = 15], 16�18 years [n = 15], and 19�24 years [n = 15]) was selected as a validation sample. Data from the remaining 415 subjects were used to develop a new equation (�Novel�) to estimate PP using age, body mass (BM), and vertical jump height (VJH) via backward stepwise regression. Independently, age (r = 0.57), BM (r = 0.83), and VJ (r = 0.65) were significantly (p 600 W) associated with predictions.
