Abstract:

This research was conducted to investigate the effects of upper leg circumference and leg length on speed, quickness and step frequency in young football players. This exercise was held with the participation of 190 people, who has the football player licensed in category of “U”(U15-U17) in Turkey Football Federation İstanbul Soma Aslangücü, Çeliktepe and Seyrantepe Of Sport Club. Information such as the demographics of the players, how many training sessions per week and how much football they played were recorded. The survey measurements were made during the first week of the pre-season. Measurements of 10-30 m sprint, pro-agility and 10-30 m sprint step frequency were performed to determine the relationship among upper limb circumference, leg length, speed and agility skills. In the analysis of the data, the SPSS 23.0 statistical program was used. The Kolmogorov Smirnov test was performed to determine whether the data were normal distributions. Relations between the data were determined by Pearson correlation test and studied at p <0.05 significance level. As a result of the analysis of the data statistically significant differences were found between the values of the upper leg circumference and leg lengths of the footballers and the results of the motoric test measurements (p<0,05). As a result the suitability of athletes' body structures to sports has an effect of enhancing performance. Leg structure of the athletes can be considered as a talent selection parameter in terms of determining the tendencies of playing football.
