The purpose of this study was to determine the effect of eight weeks interval training program on the speed and leg power of
University football players. The variables investigated were age, weight, height, jump height, speed and leg power. One
group pretest-posttest experimental study design were employed for the study. Three hypotheses were formulated and tested
in the study. Twenty-two random selected University of Ibadan soccer players formed the sample for the study. Data
collected were analyzed using the means, standard deviation and significance difference between the pretest-posttest main
variables were determined using paired t-test. The alpha level was set at 0.05 level. Based on the findings, it was concluded
that the interval training program increases the speed and jump height of the soccer players significantly but the leg power
did not improve following the eight weeks of training session. Therefore it was recommended that the plyometric exercises in
the training program should be modified in further studies for improved power performance
