This study aims to identify some anthropometric measurements of the lower extremity of the stage of ascent in the long jump. The research sample was chosen in a deliberate way, represented by the number (3) players who were registered in the Sports School and the National Project for Gifted Students, and (3) players were selected for the exploratory study, , where each player performed (3) attempts, the best (1) attempt was selected by each player and the rest of the attempts were excluded, according to the results of the kinematic analysis and the numerical level, and some anthropometric measurements were taken for the lower limb (total length, length of the lower limb, Thigh length, leg length, foot length, total weight, and numerical level), and the study was subjected to an analysis of some ascending stage variables (height of the center of gravity at the moment of push, time of push, instantaneous speed of the center of gravity at the moment of payment for the skill of long jump). The results showed that there is a correlation with Statistical significance between some anthropometric measurements and the stage of ascension, and it became clear that the greater the weight of the player, the greater the time of pivot and vice versa, the higher the values of those anthropometric measurements (height - lower limb length - body weight - foot length) the greater the strength The result for the center of gravity of the body and vice versa, that the athlete who was suitable for his body weight and muscle mass was the best in producing an appropriate net force and vice versa
