The current research aims at designing motor speed exercises using elastic resistance and identifying its effect on developing the performance level of Bek Chagi and Up Dollyo Chagi kicks in Taekwondo Junior performers. The researcher used the quasi-experimental approach with one group design (pre-/post-tests) on a purposefully chosen sample of 12 taekwondo junior performers (10-12 years)-Tanta Sports Club Season 2009-2010. Results showed that speed exercises using elastic resistance had positive effects on developing the performance level of Bek Chagi and Up Dollyo Chagi kicks in Taekwondo Junior performers as the percentage of improvement between pre- and post- tests ranged from 8.64% and 12.88%. speed exercises using elastic resistance had positive effects on improving physical fitness elements related to technical performance as the improvement percentages of motor speed, muscular ability, motor range and balance were 4.65% - 2.44% - 0.57% - 1.4%, consecutively. Using training aids (elastic cords) contributed greatly in this improvement.
