The best performance of soccer practitioners is certainly a consequence of regular football training, which also seems to bring acceleration to physical growth (Navarro F, 2000). The aim of this study was to give evidence on changes in physical parameters to young players throughout 5 months of training in football teams in Shkodra. Selection of the sample measurements were made in 2 teams of the city of Shkodra. In these measurements participated 78 boys players in the first and second phase of the measurements for a period of 5 months. The participant undertook anthropometrics parameters evaluation and performed three speed test (10m and 30m sprint test, speed and agility 10x5m). The necessary measurements for testing were: for the maximum capacity of the Vo2max oxygen (Andersen test) and strength tests. The difference between the first and second test (T2- T1) results of 10 m, presents the following values: mean of improvement 0.26 s (standard deviation 0.26 s and average error 0.04 s (p = 0.00)). Meanwhile, the difference between the results of the first and second tests of 30m velocity (improvement) is the following: average 0.18 s (standard deviation 0.37 s and average error 0.06 s (p = 0.00)). The difference between the results of the first and the second aerobic capacity tests is the following: average 26.6 m (standard deviation 126.28 m and average error of 51.55 m (p = 0.63)). The difference between the results of the first and second tests of the lower leg limbs presents the following values: mean -0.06 times (standard deviation 0.20 times and standard error of 0.03 times average (p = 0.05)). The results of the study showed the impact of training load at different stages of the training cycle for linear running speed, changes in speed, strength, and aerobic capacity to new football players in Shkodra. These results can serve as a basis for comparisons with colleagues in similar research studies. We have noticed that the speed performance and the ability to quickly change the direction of the players have improved throughout the observation period. For aerobic capacity, we did not notice a major improvement during the pre-season training period, while at the end of the season, sustainability increased slightly. We conclude that the training process in the youth plays an important role in the development of young players and positively influences the development of individual athletic performance components.
The objective of this study is to examine some physical fitness characteristics of 13-14 years old male football players. A total of 74 children were included in the study who participated in FCBescola, Kartepe 2013 football camp. 46 of them are licensed active male football players, (n=22) 13-year-olds and (n=24) 14-year-olds who are playing in different sports clubs. 28 of them are sedentary males, (n=13) 13-year-olds and (n=15) 14-year-olds, who are living in Children Welfare Homes. Measurements of height, weight, body mass index, Illinois agility test and 30-meter sprint, flamingo balance test, grip strength and sit and reach test were carried out. The data obtained were recorded with SPSS 20 program. Independent t test was used to find out the differences between groups, while Pearson Correlation test was used to analyze the associations between the variables and the level of significance was taken as p<0.05. For 13-year-old footballer and sedentary groups the results were found as follows, respectively: body mass index (18,80±1.20 and 20,09±1,76) Illionis agility test (18,92±2,01 and 21,23±2,07 sec), 30 meter sprint (5,22±1,35 and 5,96±1,86 sec), balance (4,50±3,07 and 4,12±2,75), right hand grip (21,2±3,0 and 16,3±1,8 kg), left hand grip (17,3±3,2 and 13,9±1,2 kg), sit and reach test (22,12±3,42 and 21,76±2,96 cm), while the results were found as follows for 14-year-old footballer and sedentary groups, respectively: body mass index (19,20±1,4 and 19,56±2,19), Illionis agility test (17,75±1,85±21,20±2,02 sec), 30 meter sprint (4,99±1,12 and 5,95±1,43 sec), balance (4,20±2,87 and 4,48±2,25), right hand grip (26,3±3,2 and 17,3±1,9 kg), left hand grip 24,0±2,5 and 15,2±2,1 kg) sit and reach test (22,12±3,42 and 22,23±3,75 cm). Statistically significant differences were found between athletes and sedentary group and between 13-year-olds and 14-year-olds in terms of Illinois agility test, 30-meter sprint, right and left hand grip strength values (p<0.05). Differences were found between some physical fitness characteristics of 13 and 14 years old male football players.

Effect of Physical Fitness Training on Selected Variables to Improve the Performance of U-17 Male Football Project Trainees in Arba Minch Town2019 •
The primary purpose of this study was to investigate the effect of physical fitness training on selected fitness variables to enhance the physical performance of Gamo U-17 male football project trainees in Arba Minch Town. For this study, an experimental design was implemented and a purposive sampling technique was used in order to achieve the intended goal. For this study, 28 Gamo U-17 male football project players were selected as the study sample, who had fulfilled the health history questionnaire, and from those, 14 were randomly assigned to the experimental group and also 14 were assigned to the control group, with a mean age of 16.0 ± 0.37 years old. The intervention group was engaged in interval training, circuit, polymeric, static, dynamic, and ballistic stretching programs for 12 consecutive weeks with a frequency of 3 days per week for 60 minutes. The physical fitness variables selected for this study were the sit-and-reach test for flexibility, the 30m acceleration test for speed, and the Illinois test for agility. Pre- and post-tests were conducted to measure the selected variables. A paired-samples T test was used to compare the mean difference between pre- and post-tests. The level of significance was set at ≤0.05%. After 12 weeks of training, the 30m acceleration and Illinois test mean difference values for the experimental group from pre- to post-test were decreased by 0.42 and 0.64 seconds, respectively, and the sit and reach test was increased by 3.64cm. Correspondingly, the mean value of the control group for 30m acceleration and the Illinois test was increased, and the sit and reach test was decreased from pre- to post-test. This result indicates that a significantly more effective change was observed in the experimental group than the comparison group due to the 12-week fitness exercise they engaged in. The findings of this study indicated that an effective physical fitness training program has a positive effect on the improvement of the physical performance of football players.

Comparison of Technical and Physiological Characteristics of Prepubescent Soccer Players of Different Ages2018 •
The purpose of this study was to compare the performance-related fitness of Ethiopian Youth Sports Academy U15, U17, and U20 male football players. The entire population was taken for participation in this study rather than a sample due to the relatively small population size (all N = 80) and ease of accessibility. The study was used agility (Illinois Agility Test), 1.5-mile run and speed (10, 20 and 40 meters sprint) to evaluate the performance related physical fitness of football players. One way ANOVA was used as a part of inferential statistics using Statistical Package for Social Science (SPSS) version 20. From the result, a significant difference has occurred at the p < .05 level in their agility, a 1.5-mile run, 10m, and 20m and 40m sprints. Therefore, it is possible to conclude that age groups are major factors for agility, a 1.5-mile run, and 10m, 20m and 40m sprint in Ethiopian youth sports academy football player.
It was aimed in our study to research the impact of certain physical parameters on components of motoric features such as speed, strength and flexibility in boys aged 13 to 15 years old playing football through regular exercises of 6-week training program. A training program of 6 weeks that includes motoric feature components were applied on a total of 56 male athletes playing football in a licensed U13-U14-U15 teams of Beylikgücü Sports Football Club in Beylikdüzü county of Istanbul. The trainings continued as 4 days a week and a game in the weekend. The first day the footballers participated in the study, their preliminary test values were taken and following the six-week training program, their last measurements were taken and later these were compared. Descriptive statistics were used in the analysis of the data acquired in the study, and Wilcoxon analysis was used as non-parametric methods in hypothesis tests. The reason why non-parametric tests were preferred was because the variables were determined not to have distributed normally in Kolmogorov Smirnov test conducted to determine whether the dependent variables showed normal distribution. The acquired findings were evaluated in the confidence interval of 95% and at the significance level of 5%. A significant difference (p<0.01) was determined between the calf, back, biceps, femur, subscapularis, triceps, abdomen, suprailiac circumference and fat measurements and right hand grip and left hand grip strength, ten meters (sprint) running, flexibility and sit and lie down measurements of the test subjects before and after the 6-week training program. In spite of this, it was seen that there was no significance difference in vertical jumping, sit-up, push-up and thirty meters (sprint) measurements. As a result, almost a twofold increase was observed in the hand grip strengths of the age group 13 – 15 in comparison to the age groups of 10-12 and 11-13, and while our study shows parallelism with the adolescent age groups in literature, it draws the attention to the twofold increase in the age group of 15.
