Abstract
Validation of predicting fatness methods in the Iranian girls with respect to the maturity process could help
to identify anthropometric risk factors. This study evaluate the accuracy of four body composition prediction
equations in the teenager students in Hamadan city .Method: The anthropometry profile of 266 adolescent
girls (12-16 ys) including ,weight (55.69±10.18 kg),body mass index (21.93±3.6 kg/m2) and percent body fat
averages (29.65±4.41%) were measured using the bioelectrical impedance analysis (BIA) as a reference
style and the selected skinfold prediction equations, ie, Durnin-Rahaman, Deurenberg , Westrate-
Deurenberg, Slaugter. Results: Significant relationship was observed between BIA and four body
composition prediction equations (p<0/05) with intervene the maturity level. However the most relationship
was found among BIA method and Durnin-Rahaman logarithmic equation (R=0.82-0.92 ,p<001).
Conclusion: It seems that physical education coaches and health-related organizations for athletic
performance and Clinical assessments of body composition in young individuals probably can accurately
utilized fat prediction, especially by applying the Diurnin- Rahaman skinfold equation.

Abstract
Although to improve balance and grasp the proprioception, recommended balance exercises, but there is not clear mechanism for the effectiveness of equilibrium training on healthy subjects. Suitable interaction of varios system of body and environment are necessary to maintain of the balance. Balance exercise is prescribed to improve balance and proprioception. There is not clear mechanism about the effectiveness of these exercise on healthy subjects. So The purpose of this study was to the Effect of 8 weeks of ankle-specific balance training on the balance and knee and ankle proprioception of adolescent volleyball players. the statistical sample of this study was 30 adolescent volleyball players in the league Golestan Which were selected as accessible and were randomly assigned into experimental and control groups. The experimental group performed 8 weeks and 3 sessions per week of ankle-specific balance. The results showed that there was a significant difference in the mean of balance and errors in reconstructing the angles of knee and ankle after exercise in the experimental group, while in the control group it was not significant. Results of this study showed that Balance Training can improve balance and proprioception in the knee and the ankle.

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.

Abstract
The purpose of this research was to investigate the effectiveness of snorkeling on teaching basic swimming skills in non-swimmer children and teenagers with fear of water. This research was an experimental type with a pre-test and post-test design with a control group. The participants were 30 children (8.95±0.64 years old) and 30 teenagers (15.06±0.71 years old) non-swimmers who were afraid of water, and the participants of each group were randomly divided into two experimental and control groups (15 people in each group). After participating in the pre-test of skills of entering the water, opening the eyes in the water, gliding, orientation in the water and movement in the water and breath holding, all four groups entered a 20-session course of swimming training, so that the experimental group with snorkel and the control group without snorkel were taught basic swimming skills by an instructor. Then all four groups participated in the post-test. The data were analyzed by two-factor multivariate analysis of covariance (MANCOVA) and Benferoni's post hoc test. The results of the findings show that the main effects of age were not significant, but the main effects of training and the interactive effects of age and training were significant. Using a snorkel in children and teenagers did not have a significant effect on the skill of entering the water, opening the eyes in the water, but it had a significant and positive effect on the skills of gliding, orientation in the water and movement in the water. Also, the use of snorkel in children and teenagers had a significant and negative effect on breath holding skill. Considering that the results of the present study show the positive effects of using a snorkel on learning the skills of gliding and orientation in water and moving in water and its negative effect on breath holding skill in children and teenagers, it is recommended that the instructors who use snorkel to acclimatize children and teenagers to the water, provide additional training to improve the skill of holding their breath.
