Individual constraints are of the factors that can effect on motor development. The aim of this study was to investigate the relationship between motor proficiency with body mass index and nutritional status in healthy boys 10-14 years old in Tehran. Statistical sample was of 120 children for BMI and 90 children for nutritional status. body mass index groups, lean, normal, overweight and obese groups nutritional status to malnutrition, average feeding and Appropriate division Who were chosen by cluster purposeful and motor proficiency was assessed using the by BOT-2 test. The results showed that the between conditions BMI, lean and normal, normal and obese, overweight and obese, there is a significant difference in motor proficiency but in other cases, the difference was not significant. As well as between conditions of malnutrition and normal nutrition, normal nutrition and proper nutrition, proper nutrition and malnutrition, there is a significant difference in motor proficiency. According to this result, body mass index and nutritional status of children in this age affects motor proficiency, which may be different BMI groups in motor proficiency in geometry and mass of body parts, mechanical factors attributed and differences in nutritional status groups to the role of food items brain growth and physical development, he said.

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.
