Objective:  The aim of this study was to investigate the effects of core stability exercise 
program on kicking velocity, sprint speed and agility performance in male adolescent football 
players. 
Design: Cross- sectional study. 
36 male football players between 12-14 years old who were voluntary to participate in the study 
and got informed consent form from legal representative included the study. 36 football players 
were devided into two groups. Study group (n= 19) was involved 8 Weeks, 3 Times a week 
core stability exercise program. Control group (n=17) attended routine football training 
program. During that process study group continued to attend routine football training program. 
Methods: Kicking velocity was evaluated with Bushnell velocity radar gun. Sprint speed was 
evaluated with 20 Meter sprint test and agility was evaluated with 505 Agility test. All the 
assessments were applied before and after 8 weeks of training for both groups. 
Statistical Analysis Plan: The data was analyzed using Jamovi (Version 2.2.5.0) ve JASP 
(Version 0.16.1). Type 1 error was set 5% and 95% confidence interval was used for all 
analysis. To determine between group differences in independent groups Independent Samples 
T-Test was used. Mann Whitney U test was used for non-parametric post-hoc analysis. In order 
to analyze within group changes Paired Samples T-Test was used. To determine numerical 
changes normality; Shapiro-Wilk, Kolmogorov-Smirnov and Anderson-Darling tests were 
used.
