Abstract
Lack of sensory information, muscle weakness, lack of coordination and position sense of joint are predictor factors of musculoskeletal disorders, and it seems that sports activities will have an effect on posture control and joint proprioception. Therefore, the purpose of this research was the effect of Pilates exercises on balance and proprioception in female students. 98 female students between the ages of 18-25 years-old and weight 57.92±7 kg voluntarily participated in this study after completing the written consent form. Of these, 91 healthy students were placed in the experimental group and 7 students with sports exemption (with medical conditions such as: recent surgery for refractive errors of the eye, cysts, etc.) were placed in the control group. The position senses of ankle and knee joints was measured using the active reconstruction test of the ankle and knee angles and static balance was measured using the Sharpened Romberg test before and after 16 intervention sessions. Wilcoxon test was used to determine the difference in pre-test and post-test (intra-group difference) and covariance test was used to compare between groups (of course, the data were normalized earlier). The results showed that after the intervention, in the experimental group, static balance increased significantly in the post-test compared to the pre-test. The position sense of dorsiflexion, plantarflexion of ankle joint and knee flexion position sense in the experimental group increased significantly in the post-test compared to the pre-test. Also, the results of the covariance test showed that there is a significant difference between the two groups in the post-test in the variables of static balance and position sense of dorsiflexion and plantarflexion of ankle and position sense of knee flexion. According to the adjusted average in the post-test stage, the experimental group performed better than the control group. The results showed that Pilates exercises are suitable for improving ankle and knee proprioception and improving postural control in teenagers and young adults.

Abstract
The aim of this study was to Compare Effectiveness motor proficiency of the nutritional status on men in different age groups ((children, adolescents and young adults)), respectively. Statistical Society study was for children all student ages 10-7 years, for adolescents all student ages 15-12 years and for Youth of all students 20-18 of Tehran University except the student physical education. The sample was 90 people in each of the age groups, the four elementary schools and four high schools in Tehran and Tehran University male students were chosen by cluster sampling. This study was a descriptive survey and comparison measurement was test of instruments anthropometric and Brvnynks- Oseretsky. The results showed that among malnutrition, moderate nutrition and proper nutrition in adolescence and adulthood motor proficiency was not statistically different ages but among children ages motor proficiency were significantly different. In addition, no significant difference between motor proficiency age groups. It seems due to the impact of nutritional status on motor proficiency, and this issue was observed in this study at an early age; therefore, children are the most vulnerable in this context and considering the nutritional status of children is very important.
