Constructing and standardizing a tests of speed force endurance of the legs for the National Center of Sports talented of Hand ball players aged (15_17) years

Abstract

The aim of this study is to develop a complex test to assess speed strength endurance among handball players aged 15–17 at the National Center for Sports Talent Care. To achieve this goal, the researchers adopted the descriptive approach using the survey method, as it aligns with the nature of the research problem. The sample consisted of 60 deliberately selected players, representing 57.14% of the research population.

Exploratory experiments were conducted to validate the test and ensure its scientific characteristics, including validity, reliability, and objectivity. The test also proved effective in distinguishing between individuals in the sample. Appropriate statistical analyses were applied to support the results. The researchers concluded that the speed strength endurance test serves as a realistic and practical tool for evaluating handball performance. It significantly contributes to improving this essential physical attribute. Therefore, the researchers recommend adopting this test for continuous player evaluation. Additionally, it can be used as a key factor in selecting qualified players for club and national teams. The study also suggests developing similar complex tests for different age groups and highlights the importance of structured, scientific training programs focused on speed strength endurance.
