There is a training protocol called 'FIFA 11+' recommended by the International Football Associations Association (FIFA) and the Turkish Football Federation (TFF) to football teams. This protocol is defined as a warm-up program used to prevent injuries in athletes. This program includes 3 parts. The first part consists of running exercises, the second part consists of exercises that improve strength, balance, muscle control and trunk stabilization, and the third part consists of advanced running exercises. The aim of this research is to determine the effect of the FIFA 11+ training program applied to young football players on selected parameters. In the U14 league category, 19 male football players who played licensed in an amateur football team (Age: 13.8 ± 0.05 years; Height: 167.25 ± 0.06 cm; Body weight: 57.59 ± 12.3 years) kg) participated voluntarily. Height and body weight measurement, 10-minute warm-up run and 20 m sprint test were performed on the athletes, respectively, on the 1st day. On the second day, a 10-minute warm-up run, reach and vertical jump tests were performed, respectively. After the applied tests, the athletes were randomly divided into two groups as experimental and control groups. Control group athletes applied the dynamic warm-up program determined in their routine training programs, and experimental group athletes applied the FIFA 11+ training program 2 days a week for 6 weeks in addition to their routine training programs. At the end of the 6th week, the previous measurements were made in the same way and the study was terminated. Shapiro-Wilk and T tests were used in the analysis of the data. According to the research findings; It was determined that the FIFA 11+ training program applied to the football players had a statistically significant effect on the jumping and flexibility performances of the athletes (p<0.05). In addition, it was determined that the program applied had an effect on the other performance parameters of the athletes, but this was not at a significant level (p>0.05). As a result; It is recommended that the FIFA 11+ training program applied to football players should be included in the training programs in order to contribute to the jumping and flexibility performances of the athletes.
