Athletics events rely on scientifically and technically sound talent identification processes based on physical tests that assess performance-related abilities, in addition to other requirements such as anthropometric measurements specific to runners. The aim of this study was to determine the most important biokinematic abilities and fundamental anthropometric measurements, and to establish normative standards for these variables to support the selection of 1500-meter junior athletes aged 13-15 years.

The study sample consisted of 200 students from intermediate schools in the center of Wasit Governorate (Al-Kut), representing 6% of the total population. Data and measurements were collected through standardized tests and instruments. The study results were classified into five levels.

The researcher concluded that continuous exposure of the sample to tests of biokinematic abilities and anthropometric measurements makes it possible to identify the natural developmental progress of individuals. Since each athletics event has its own specific requirements, the selection process should focus on these criteria. The researcher recommended that the selection of athletics runners should primarily rely on the key biokinematic abilities and anthropometric measurements relevant to each event. Furthermore, the physical education curriculum at intermediate schools should include training and general physical fitness preparation to help students achieve desirable athletic performance levels.
