الملخص EN

The study aimed to identify the relationship of some anthropometric and physical measures with the performance of javelin event of students in physical education department at the Palestine Technical University "Khadouri," in addition to determine the most anthropometric and physical measures that contribute to the performance of the javelin throwing event.

To achieve that, this study was conducted on random sample that consisted of (38) students from physical education students.

The researcher conducted the anthropometric measures of: (body weight, body height, height of sitting position, and lengths of: thigh, leg, heel, toe, Foot, arm, upper arm, forearm and hand), and physical measures of: (maximal speed (sprint 30-m), power of arms and chest (push- ups Test (10s)), strength of trunk extensors, handgrip power, and push of medicine ball (3kg)).

SPSS program was used in data analysis.

The study results showed that there was a significant relationship between the (body height, body weight, body height of sitting, maximal speed, explosive power of arms and chest muscles (10s), strength of trunk extensors, and handgrip power) the performance of the javelin throwing event.

Also, the results indicated that body height and explosive power of arms and chest muscles (10s) were the most important variables that contribute to the performance of the javelin throwing event, and therefore the study reached the following equations: Performance of javelin (m) = - 89.459+ (69.780× height (m)) Performance of javelin (m) = 13.451+ (1.713× Push- ups Test (10s) (cm)).

The researcher recommends the necessity of coach’s concentration in the universities on the height and upper extremity power when selecting the students in javelin throwing event.
