A strong negative correlation among the actual body height and reaction time may be related to two fac- tors: a) the relationship among stature and maturity, because physiologically more matured athletes also have greater maturation of the central nervous sys- tem and, consequently, greater myelination of neurons [34]. b) The relationship among the stature and lean mass (LM) of the lower limbs (LL), because a greater amount of LM of LL, and consequently, muscle tis- sue, can result in higher rate of force production [35], resulting in increased speed of withdrawal of the foot on the contact platform.
