Guest guest Posted September 8, 2002 Report Share Posted September 8, 2002 Dr Siff, Verkhoshansky, who pioneered plyometrics training, said that it is necesary to have a feet contact time of under 160 thousandths of a sec when the athlete performs a drop jump. My question is: what's happen if the athlete has a feet contact much longer than 160 (for example, 200)? Is it not plyometrics? Is it just a simple jump? Bosco wrote the following table about time contact: 145 - 160 = excellent. 160 - 175 = good. 175 - 190 = regular. >190= poor. Sincerely, Andrés Esper La Plata - Argentina.
