Abstract:
The purpose of the study was to find out the effect of interval training on agility, speed and core 
strengthfor football player students of Mena secondary school. Thirty football players were 
selected as subjects. The selected subjects were divided into two groups of fifteen each (n=15). The 
ages of the subjects ranged from 18 to 19 years. The experimental group was high intensity interval 
training group, and a control group. Initial test on 35 meter run, Illinois agility and plank test was 
conducted for all the groups and the performance was recorded for these groups. The experimental 
group was administered for twelve weeks training. The control group was not given any treatment. 
After 12 weeks the final test was taken on 35 meter run, Illinois agility and plank test for 
experimental group and control group. The collected data was statistically analyzed by using SSPS
Version. The result of the study was interval training group was significant improvement in 
compared to the control group.The schedule of training was three days per week (Monday, 
Wednesday and Friday)for three Months(October, November and December2022).The study 
wasExperimental study. Pre &Posttest measurements were taken from trainees before & after the 
experimental period of three months. The results of both control and experimental group was 
analyzed and putted in the form of mean and standard deviation.The result indicated that the pre
and posttest ofcontrol group students wasas low. Butthe results of pre and posttest ofexperimental 
group students was good. The three parameters (Agility, Speed and Core Strength)of the 
studentshad significantly improved through interval training. The result concluded interval 
training methods was good for improvement of agility, speed and core strength of the students.
