The aim of this paper is to study the relation between muscles electrical activity and knee movement during walking for patient with patellafemoral pain by measurement both of electromyography (EMG) and changing of knee angle by electro-goniometer. T he start and end of the gait cycle were determined by foot sensors, A program was designed for signal processing of the data, Testes were carried out at Hamish hospital in Damascus. Subjects were divided into two groups: 46 normal subjects and 21 patient. Final results also showed that hamstring group activity and galf group activity decreases during stance phase because knee cancel it first flexion with increase in quadriceps femoris activity to keep extension of knee. In swing phase, it is noted that the decrease in knee flexion and it depends on the increase in quadriceps femoris activity in all the period of swing phase, but hamstring group activity increases to keep hip instability, that is, it responds to increase activity of quadriceps femoris with less knee flexion. The activity of subject muscles in the period of gait cycle is less than normal muscles.
Soccer game is one of the more games that players are exposed to sports injuries and the reason for this is due to the large increase of the practitioners of this game as well as the characteristics of this game that are frequently the friction betwe en the players. Therefore, this studyis concerned to identify the causes leading to the occurrence of injuries in the lower limb among soccer players in the clubs lattakia city . In addition the comparison between the clubs of lattakia city from where the occurrence of lower limb injuries by variables ( Type - Classification of dangerous - Location – Form ) to the soccer players. The study sample included 43of the players from men's clubs in the city of Lattakia, where the questionnaire was designed and distributed to injured players and then were collected questionnaire by the researcher. The study found that there is a difference in the causesleading to the occurrence of sports injuries among soccer players in the club and another. In addition to that . different types of infections , forms , classification of seriousness and where they occur in the lower limb among football players between club and another .
The research aims at identifying the relationship between Relationship of Some Physical Measurements (Weight, Total Height and Length of the Lower Limb) with Junior Footballers Accurate Scoring. The descriptive methodology has been used in the styl e of correlation relationship. The research sample included the 15 footballers from the youngsters in Jableh Sports Club. An assumption has been established of a relationship of statistical significance between Relationship of Some Physical Measurements (Weight, Total Height and Length of the Lower Limb) with Junior Footballers Accurate Scoring. The suitable statistical tools, used in this research, shows the absent of meaningful relationship between Some Physical Measurements (Weight, Total Height and Length of the Lower Limb) with Junior Footballers Accurate Scoring. The researcher recommends the following: 1- conduct similar studies on different age groups and advanced skills in football 2- conduct similar studies on other football game skills.

The study aimed to identify some of the selected anthropometric measurements and the explosive strength and the relationship between them in addition to the impact of practical program for the first semester of college on each of the explosive streng th and the selected anthropometric measurements of the female students in the first year in the Faculty of Physical Education at Tishreen University. To determine that, the study was conducted on a sample of (45) students and used the descriptive approach, and collected physical measurements as well as selected vertical jump test of fortitude. The study showed the following results: The existence of a correlation between the explosive power and the length of the lower limb and, a lack of correlation between the explosive strength and the length of the trunk with the head. The researcher recommended that attention should be payed to the standards of physical measurements as criteria for admission to the terms of reference for physical education .The researcher also recommended the faculty can take advantage of the connectivity relations between measurements and physical fitness components in the development of motor skills and capabilities.
