The effect of special exercises according to the body momentum index on developing some biomechanical variables and the achievement of long jump for advanced athletes.

Abstract

The scientific and technological advancements in various sciences have led to significant progress in different fields of life. This development did not occur in isolation but resulted from multiple scientific experiments. The sports field is one of the areas that utilize these sciences (training, biomechanics). The importance of the research lies in proposing key scientific solutions by designing special exercises based on the body momentum index and their impact on some biomechanical variables and the achievement of long jump for advanced athletes. The researcher aimed to develop appropriate solutions to enhance performance through specialized exercises aligned with the body momentum index to improve biomechanical variables and achievement.

For the research methodology, the researcher adopted the experimental method with two groups (control and experimental) using pre- and post-tests. The research sample consisted of 10 long jumpers from the Middle Euphrates region. The specialized exercises based on the momentum index were applied over two months, with three training units per week. The researcher concluded that the momentum-based exercises contributed to the development of biomechanical variables and performance among the research sample. Additionally, significant differences were observed between the two groups in favor of the experimental group during the post-test.
