Abstract

The aim of this study is to establish a reference of the cienanthropometric parameters in footballers of different ages in school ages and the relationship with certain components of physical fitness both specific to this sport, speed of movement with and without the ball, flexibility of the isquiosural muscles and not specific, such as the muscular development of the flexors of the hand, and to compare them with other populations. The sample (n) is formed of 136 boys between the ages of 9 and 14. All practise football and are federated in different teams of the Autonomous Community of Aragón. We took the following anthropometric measurements: weight, height, skin folds perimeters and diameters and held the following tests: 10×5 m. with and without ball, manual dynamometry and front flexion of the trunk. In the cineanthropometric results obtained we can see how there is and decrease of the total of skin folds directly proportional to age and an increase of IMC. We did not see any standard differential in the distribution of fat in different ages. The data of the test shows the decrease, inversely proportional to age, the difference of the times obtained in the performance of the 5×10 m. test with and without ball, as well as a statistically significant correlation between muscular development and co ordination in the management of a mobile. We see it as necessary to instil a work habit in flexibility from an early age as an important aspect in the prevention of injuries and possibly in a better performance.
