All participants performed a Countermovement Jump (CMJ) test. PP was calculated using Duncan (PPDUNCAN), Gomez-Bruton (PPGOMEZ) and PECMJ formulas. A model with PECMJ as the predictor variable showed a higher predictive accuracy with PPDUNCAN and PPGOMEZ than CMJ height (R2 = 0.99 and 0.97, respectively; ELPDdiff = 1037.0 and 646.7, respectively). Moreover, PECMJ showed a higher linear association with PPDUNCAN and PPGOMEZ across BMI groups than CMJ height (βPECMJ range from 0.67 to 0.77 predicting PPDUNCAN; and from 0.90 to 1.13 predicting PPGOMEZ). Our results provide further support for proposing PECMJ as an index to measure PP of the lower limbs, taking into account the children's weight and not only the height of the jump. Therefore, we suggest the use of PECMJ in physical education classes as a valid method for estimating PP among children when laboratory methods are not feasible.
