Abstract
The aim of the study is to introduce the mechanical analysis of the time variable in the Arab jump and to show the relationship between the variables of time in the Arab jump and some physical abilities. The researcher hypothesized that a “morale” relationship existed between the variables of time. He also assumed the existence of a statistical relationship between the variables of time and some physical abilities. The researcher used a descriptive method. His study is based on eight female gymnasts from Lerbick school in Lundt that he videotaped. To treat the values of variables of time and physical abilities, the researcher used a number of statistical rules. He used (SPSS) from which he fond …. The results were presented and discussed. The results shows that there is a statistically significant relationship between the explosive force of arms and shoulders and hands pushing time and time for putting hands on the floor, between speed and the total duration of the jump, between the duration of the first arc, the time for putting hands on the floor and the duration of the second arc, between the time of pushing hands and the time for putting hands on the floor. By cons, the results do not show a statistically significant relationship between the flexibility of the shoulders and the variables which are the subject of the study. The most important results were that: 1. the good explosive force of arms and shoulders shortens the time necessary for hand pushing and for putting hands on the floor. 2. High speed can help the player to achieve the jump in a shorter time
