摘要：Objectives: This study aimed to emphasize the dynamics of time and movement speed during the 60 m – little girls I,50 m – little girls II,and 40 m – little girls III events.Material and methods: In order to underline the results during the qualifications and finals,we used as research methods: the study of the specialized literature,the observation,the electronic recording,the statistical-mathematical method and the chart method.The results were recorded using the Alge Timing Optic 2 electronic timing system,made by the Alge Timing Company.24 subjects participated in this research (8 little girls I,8 little girls II,8 little girls III).The hypotheses started from the belief that the time and the movement speed have small oscillations between the qualifications and the finals races,and that most little girls run better in the final race than during qualifications.The recorded and analyzed results emphasize the manifestation of the movement speed in the three age categories during the short sprint events conducted in the winter competition season.The results prove that in nearly all cases the children cannot improve their values in the final race,in comparison with the series.The conclusions have emphasized the fact that the time and the movement speed,in most of the studied female runners,recorded small oscillations between qualifications and the final races,which partially confirms the first hypothesis,but also the fact that most of the little girls run slower in the final race than in the qualifications,which negates the second hypothesis.
