This contribution deals with speed abilities of the pupils in short-distance runs in athletics. In scientific literature there are lots of studies that analyze speed performance in adults. These studies showed the correlation between speed and anthropometric measurements and between performance and indicators of speed (acceleration, frequency and length of steps). The aim of our study was the description of speed performance about children to verify similar relation as found in adults. We investigated speed abilities using the 50 m sprint test with standing start. The sample of subject consisted of 90 male and female pupils (45 male and 45 female) aged between 6 and 8 years old: beginner in athletic practice. We analyze performance with chronometers and photocells and we collected for each subject the anthropometric measurements (weight, height, torso and lower limb length), total time, intercepts every 10 meters and frequency of the step every 10 meters. The Anova 1 Way and Tukey-Kramer post hoc test was used to verify if the results were statistically significant among intercepts. In general, boys run faster than girl, total time decrease as the age increase and the interpretation and management of the effort in sprint change in the different age. Furthermore, the correlation between speed and anthropometric measurements were not always verified and the 20 meter cut-off was the general point where the run decreased. In conclusion, the performance in children could be improved using technical exercises about the support phases and educational approach to extend the effort.

Abstract
This contribution deals with speed abilities of the pupils in short-distance runs in athletics. In scientific literature there are lots of studies that analyze speed performance in adults. These studies showed the correlation between speed and anthropometric measurements and between performance and indicators of speed (acceleration, frequency and length of steps). The aim of our study was the description of speed performance about children to verify similar relation as found in adults. We investigated speed abilities using the 50 m sprint test with standing start. The sample of subject consisted of 90 male and female pupils (45 male and 45 female) aged between 6 and 8 years old: beginner in athletic practice. We analyze performance with chronometers and photocells and we collected for each subject the anthropometric measurements (weight, height, torso and lower limb length), total time, intercepts every 10 meters and frequency of the step every 10 meters. The Anova 1 Way and Tukey-Kramer post hoc test was used to verify if the results were statistically significant among intercepts. In general, boys run faster than girl, total time decrease as the age increase and the interpretation and management of the effort in sprint change in the different age. Furthermore, the correlation between speed and anthropometric measurements were not always verified and the 20 meter cut-off was the general point where the run decreased. In conclusion, the performance in children could be improved using technical exercises about the support phases and educational approach to extend the effort.File | Dimensione | Formato | |
