الملخص EN

The study aimed to identify the effect of muscle fatigue on some of mechanical variables and its relationship with head shoot accuracy for football players.

The researcher used the descriptive method, study sample was chosen randomly and consisted of 12players from Mutah University football team.

The study data were collected through videotaping and analyzed by Kinovea program.

Statistically, the researcher used SMA, standard deviation, T test and Z test.

The results of the study showed a negative effect of muscle fatigue on of both mechanical variables and the accuracy of head shoot skill, except the variable of trunk angle shooting moment.

The study also showed that the mechanical variables have a consensual relationship with head shoot accuracy for football players where fatigue did not affect statistically on this relationship.

The researcher recommended increasing the training loads to make a positive impact on the mechanical variables and development of training programs to improve the general physical condition and the elements of endurance and muscle compatibility to avoid the low of head shoot accuracy skill for football players in light of muscle fatigue..
