دراسة تحليلية مقارنة لبعض المتغيرات الكينماتيكية المؤثرة في المسافات المكونة لسباق 200 متر حرة

الملخص EN

The study aimed at identifying some kinematic variables affecting the distances of 200m freestyle race among the swimmers of the Specialized School for Swimming.

Three (3) swimmers have been intentionally chosen to be the subjects of the study.

The kinematic variables of each player have been extracted by the motor analysis (kinovea) program and their data values then compared.

In light of the results, the researcher found out clear big differences in the values of these variables among the swimmers themselves and between each distance of the race distances for each swimmer which led to a big variation in the achievement (final time).

A matter that requires reforming procedures in the technical performance and physical characteristics development for the swimmers of the Specialized School in 200m freestyle event in order to reduce the final time (improving achievement).

The Importance of the research was in establishing a strong physical base by designing and applying exercises with different styles that aim at developing strength types in soccer players aged 13 – 14 years old.

The problem of the research was
