The purpose of this research was to design and implement a system for the surveillance of sports injuries in students. Sports injuries of male and female high school students in Ilam province were recorded by physical education teachers using online methods and paper forms during one academic semester. At the end, a questionnaire was used to survey them regarding these methods. The research is of a descriptive-comparative type and Chi-square (x2) was used at the significance level (P<0.05) to analyze the results. A total of 151 injuries were reported, of which 76 injuries (50.4 percent) were registered with the online method, 70 injuries (46.3 percent) with the online paper method, and 5 injuries (3.3 percent) with the paper method. Online registration (146 injuries) is significantly more used than paper registration (75 injuries) (p=0.001) physical education teachers give the reasons for using the online method more: availability, easier working with it, and recovery It is easier to record information. On the other hand, they mentioned the interruption and slowness of the internet speed as things that can cause disruption. According to the results, it seems that the use of online methods is more effective in registering sports injuries in schools.

The purpose of the present study was to compare some antropometric characteristics of 11-14 years old male students in high, average and low Socio-economic Status. 610 students from public schools in three educational districts of Isfahan were randomly selected by clustral method. Then the Subjects were located in three low, average and high Socioeconomic status groups. Height, weight, triceps and culf skinfold thichnesses were measured. Result showed that there were Significant differences between three groups in weight, triceps and culf skinfold thickness, sum of two skinfold thickness (culf and triceps) and percent body fat. Also there were no Significant differences between three qroups in BMI and height. Result showed that weight of students with high socioeconomic Status was greater than the Students with average and low socio economic Statues. Also the skinfold thickness of triceps, calf and percent body fat of students with high socioeconomic Status were greater than students in low socioeconomic status. It seems that the childreen in high socioeconomic status have more weight and fat than children in low socioeconomic status. Other researches have Concluded that the girls in high socioeconomic status have lower percent body fat compare to children in low socioeconomic status.

The purpose of this study was to evaluate the effect of eight weeks strength and
plyometric trainings on knee joint position sense. In this study, 45 male students
(21.7±2.17years, weight 69.7±7.89 kg, and height 177.2±5.83cm) volunteered
and selected as subjects to participate in this semi-empirical study. Subjects
divided in three groups include strength (n=15), plyometric (n=15) and control
(n=15). Strength group trained squat, leg flexion and leg extension and
plyometric group trained depth jump, Split squat jump, rim jump and box to box
depth jump. Joint position sense measured at three angles 30, 45 and 60
degrees in knee joint by Biodex Isokenitic system 3. One-way ANOVA was
used for analysis of data. Results of study showed that trainings significantly
improve the joint position sense in initial angel (30degree) on active
reproduction and in initial and final angels (30 and 60 degrees) on passive
reproduction. In addition, comparison of trainings revealed that strength training
in 30 degrees and plyometric training in 30 and 60 degrees significantly improve
the joint position sense. Between two methods of training only on passive
reproduction at 60 degree, significantly difference was observed (p≤0.05).
These protocols can use in rehabilitation to improve proprioception and
neuromuscular coordination.

Pronation distortion syndrome is one of the most common abnormalities in the body that causes distortions in the structures of the skeletal structures of the lower extremities and increases postural sways. The purpose of this study was to determine the effect of 12-week corrective exercises on postural sways in male students with pronation distortion syndrome. In this semi experimental research, 30 volunteers had pronation distortion syndrome, were selected and then randomly and equal divided into two groups of control and experimental (n=15). The experimental group performed corrective exercise consisting of inhibitory, stretching, strengthening, and integrated exercises for three months, but the control group carried out their routine exercise. The postural sways conterol were evaluated before and after of the three month of performing corrective exercises. Independent and dependent t-test were used to analyze the results (P≤0/05). The showed significant improvement in postural sways control and ground reaction force (P≤0/001), effect size 0.8 and 95% confidence interval after three months of corrective exercise, but in control group there was no significant difference (P≥0/05). In addition, after intervention, the experimental group were significantly lower in postural sways conterol and ground reaction force than the conterol group (P≤0/001), but this difference was not  significant in the pre-test (P≥0/05). It seems that systematic corrective exercise led to improve the activity of the muscles responsible for body sways conterol, which also reduces postural sways and ground reaction force in people with pronation distortion syndrome, so it is recommended that researchers, trainers, and specialists consider systematic corrective exercise in order to improve posture sways conterol and ground reaction force in people with pronation distortion syndrome.
