Examination of flexibility and sprint performance values of adolescent footballers

Abstract

The flexibility is effective to provide an optimal body development appropriate to needs of sports branch and development of physical factors such as strength, speed and sport technique. The purpose of this study is to compare the flexibility and sprint performance values according to age and gender, the features of physical fitness performance of boys and girls who play football. Total of 172 volunteer's measurements were evaluated which consisted of 99 men footballer whose average age are 12,919 0,078 years and 72 women footballer whose average age are 12,973 0,065 years. Age, height, weight, BMI, flexibility, 10 m and 20 m speed measurements of groups were taken. Multiple Regression Analysis was utilized for searching the relationships between flexibility and detected features. Formed by Stepwise variable selection method, the Multiple Regression Analysis was allowed to consist of statistically significant variables. Two sample T-test was used to compare gender in terms of average speed of 10 m and 20m. 10 m and 20 m sprint performance determined that the significant difference is in favor of the male players according to gender. The relationship between speed and flexibility was varied by gender. The significant relation was found between flexibility values and 10 m sprint performance values of male footballers (P=0,002), while the significant relation was found between flexibility values and 20 m sprint performance values of female footballers (P=0,009).In order to improve the sprint performance, which is a specific skill of football, flexibility of the muscles should be trained with a program at an early age.

Analysing Woman Footballers^some Physical Rates According to Their Playing Positions and Ages

“…There was no significant difference in the elasticity values (p> 0.05). According to Mendes et al the elasticity values of the adolescents were found to be 4,8 ± 0,4 cm (Mendes et al, 2015). Rye recorded the elasticity values of girls aged 12-14 years as 19.66 ± 4.35 cm, 22.38 ± 5.29 cm (Çavdar, 2006).…”

“…Thomas and his colleagues found that the footballers average speed of 10 m and 20 m were 1.69 ± 00.1 s and 3.10 ± 00.1 s, respectively (Thomas et al, 2012). Mendes and al. found that the sprint grades of 10 m and 20 m were 2.02 ± 0.01 s and 3.82 ± 0.03 s, respectively, in adolescent soccer players (Mendes et al, 2015). AugheyWyckels et al found that 20 m sprint averages were 3.47 ± 0.13 sec.…”

“…Measurements were made with the photocells placed at the start and end of the 10 meters running distance. The test was performed two times and the best rating was recorded (Mendes et al, 2015).…”

“…Por otro lado, en el contexto de un diseño experimental llevado a cabo con nueve jugadoras juveniles de fútbol, Mathisen & Pettersen (2015) también valoraron el tiempo empleado en los primeros 10 metros de un test de sprint de 20 m, y encontraron valores medios de base de 1,99 s y 1,95 s en dos grupos con edades de 15,5 ± 0,7 años y 15,1 ± 0,5 años (media ± desviación estándar). Y Mendes et al (2015) aplicaron el test de sprint de 10 m a 99 varones y 72 mujeres jugadores de fútbol con rangos de edad de 11,0 a 14,0 años y 12,0 a 14,0 años, respectivamente. Ellos encontraron un tiempo medio de 1,86 s en varones, y 2,02 s en mujeres.…”
