Abstract EN

The importance of the research is summarized in the study of the evaluation of the static jump test (the long jump from stability), which is affected by several factors, including mechanical performance, body weight and its anthropometric measurements, as it is not scientific logic to compare the distance or displacement of the jump between individuals of different weight because it increases the inertia of the body It increases the resistance to moving it as well as the difference in the amount of mechanical work performed The goal of the research is the following: 1- Identify the mechanical work values for the static jump test of the research sample.

2- Identify the values of the static jump test of the research sample.

2-Identify the correlation between the hierarchy of the static jump test values and the mechanical work The researchers used the descriptive approach to suit the nature of the research.

The research sample consisted of (30) students and the data were statistically treated using the arithmetic mean, standard deviation, median, mode, coefficient of variation, and ranks correlation.

The researchers concluded the following: 1-There is no significant correlation between the ordinal sequence of the static jump test and the mechanical work order sequence of the static jump test.

The most important thing recommended by the researchers is the following: 1-Adopting the mechanical work of the static jump test instead of relying on the horizontal jump displacement to avoid the influence of the player's mass on the jump displacement.

2-Adopting the measurement from the front of the foot (the metatarsal) in calculating the displacement cut to the final position of the laboratory
