The purpose of this study was to investigate the effect of three different resistance levels of using  rubber  bands  during  a  warm  up  protocol  on  vertical  jump  performance.  Quasi  experimental  design  was  used  in  this  study.  Seventeen  recreationally  active  males  aged  between  20  to  25  years  old  were  randomly  selected.  The  participants  underwent  four  sessions consisted of (a) familiarization warm up, (b) warm up with orange color rubber band (high  level of resistance), (c) warm up with blue color rubber band (medium level of resistance) and (d)  warm up with green color rubber band (lower level of resistance). At the end of every session, the  participants performed the squat jump on the force plate. The data on force, power and height of  jump were collected and analyzed. Repeated Measure One- way ANOVA was utilized for data analysis.  The force result indicated that the mean force (N) obtained  for.....
