The aim of this article was to monitor and improve the number of steps on speed through a 12-week training program for young players in the city of Elbasan. The 12 week training intervention was carried out with the focus on biomechanical running parameters and mainly on the densities of the steps during the training sessions. The participants in this study were 28 younger players 15.1 ± 0.3 years (control group and intrusion group). The speed time (50m sprint) was evaluated during the sprint test (50m) and also the anthropometric parameters (weight, height, body fat in percentage) were measured at both study times (first T1 measurements and T2 second measurements). Skin thickness measurements were used to estimate the percentage of the body fat of the child. Data from the analysis on this research study by groups show that there is an improvement in mean values for step counts from T1 to T2 as follows; for control group by 1.3 steps (SD 0.8 seconds; t= 4 p=0.01) while for intervention group there is an improvement also by 2.8 steps (SD 1.1 steps; t= 5.7 p=0.005). Finally, statistical analysis show a significant difference in improvements (T1 to T2) between groups for the number of steps (p= 0.03) in favor of the improvement of the intervention group.

Several studies have investigated the association between strength and speed, showing that stronger athletes perform better during sprint performances (Baker & Nance, 1999). Moreover, the aim of this study was to evaluate the correlation between sprint performance and anthropometric parameters. Subjects were 32 youth soccer players. The age of participants was 15.1±0.3 years. Speed time (50 m sprint) was evaluated during sprint test, and anthropometric parameters were measured (weight, height, percent body fat). Correlation analysis (Pearson test) was performed to evaluate the correlation between speed and anthropometrics. Results showed correlation between body weight and speed (r=-0.041 Sig=0.834); BMI values and speed (r=0.231; Sig=0.236), body height and speed (r=-0.384; Sig=0.044); percent body fat and speed (r=0.440; Sig=0.019).In conclusion, the results of this study show no significance association between body weight and BMI with sprint performance and significance correlat...

Development of speed and strength in young football players aged 10-12 years2023 •
The present study aims to improve the efficiency of the specialized physical training process, depending on the targeted motor qualities, in our case speed and strength, is an increasingly accessed topic in search of obtaining a higher yield in a more efficient time. The study was conducted on a sample of 16 subjects, members of the U12 group. In the case of the applied program, we seek to achieve the proposed objectives, and by carrying out the planned, measured and interpreted physical training, we want to highlight the essential moments in the formation and development of the proposed program.
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.

Effect of 12-Week Functional Training Intervention on the Speed of Young Footballers2019 •
The aim of the research was to verify the functional state of young football players using selected tests of the Functional Movement Screen (FMS) protocol, as well as the impact of the 12 weeks of functional training on the speed parameters. The research was conducted on 20 highly competitive young (U17) football players. Research project was conducted in two stages: in the first part of the study, the functional assessment was made by using the FMS test, then the measurement of the speed parameters was done with the Microgate photocells system. Results showed a significant improvement in the functional state of young football players: FMS 1 (45.2% of difference, p = 0.004), FMS 2 (24.3% of difference, p = 0.012), FMS 3 (48.5% of difference, p = 0.001). After the functional training program, there was also an improvement in the parameters of the acceleration and velocity: acceleration between 5–10 m and speed between 10–30 m shows significant improvement (expressed during covering a...
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.

Effect of Leg Length With 100m Sprint Running Speed on The Men’s Soccer Team at SMA 1 MataramRunning is one of the movements needed in soccer. A person in running motion has several factors that affect his speed. These factors include internal and external factors. One of these internal factors is leg length which is thought to have an influence on the frequency of a person’s footsteps so that they produce different speeds. This study aims to determine the effect of leg length on the 100M sprint running speed on the men’s soccer team at SMA 1 Mataram. This research method is an experimental method that is carried out directly by measuring leg length and running speed with 20 people as respondents from the entire soccer team at SMA 1 Mataram. There is an effect between leg length and 100M sprint running speed on the male soccer team at SMA 1 Mataram after the normality test p> 0.05 is 0.140 and the relative coefficient is 0.965, where the two characteristics above show a strong influence that has processed through the SPSS application.

Peculiarities of the Influence of Fitness Special Means on the Speed and Strength and Coordination Indicators of Young Football PlayersBackground: The problem of increasing coordination and conditioning abilities of young football players largely determining the level of manifestation of such motor qualities as agility, speed and strength can be solved with the help of additional means of fitness. The purpose is to study the effect of a specialized fitness program on the indicators of speed-force and coordination abilities of young football players. Material and methods: The pedagogical experiment lasted 6 months, involving 40 athletes-football players in the age of 8.97±0.04 years old (height: 139.72±1.08 cm; body mass: 31.71±0.66 kg). Children of the experimental group (n=24) were engaged in a specially designed fitness program, including exercises with different fitness equipment in the transitional mesocycle 2 times a week for 45 min, and in the preparatory one - once a week (45 min). The remaining 16 players served as a control group and continued their traditional training. Coordination abilities were determined with the help of tests "running 30 m with the ball at least 3 touches", "hitting a stationary ball from a running distance" (corridor of 10 m) and "juggling with a ball". To assess the speed and strength abilities we used "speed of running for 30 m", "long jump from a place", "pulling up from the high bar". Statistical processing was performed using Microsoft Excel and software package "STATISTICA 10.0". The parametric Student's t-test was used in the study. Differences were significant at P<0.05. Results: We found that the experimental group significantly improved the speed of running for 30 m and long jump by 5.1% and 1.9% (p<0.01), as well as the pull-up from hanging on the bar by 20.9% (p<0.01). Coordination indicators (running for 30 m with ball handling and juggling) changed more significantly by 30.7 % and 26.6 % (p<0.001), respectively. Kicking a stationary ball from a running distance changed by 4.10% (p<0.05). Conclusion: If we apply additional fitness programs with different sports equipment during the training of football players of 8-9 years old, the indicators of coordination and speed-force abilities will improve considerably.
