Purpose: Prediabetes refers to a condition where the level of fasting blood sugar reaches 100- 125 mg/dl. The prediabetes pervasiveness is growing throughout the world. The main objective of the present research is the exploration of the body composition and anthropomorphic differences among prediabetes and normal people for finding the plans for scanning prediabetes and the impact of exercise on it. Method: The present descriptive cross-sectional research conducted on 251 people. The signed informed consents and information of the education, age, exercise etc. gathered. Then, blood glucose tested, and 133 and 118 participants respectively had been chosen for the prediabetes and normal groups. Digital scales, wall stadiometer, tape measure and body composition monitor had been employed to measure anthropomorphic and body composition indices. Results: Total pervasiveness of prediabetes was 52.98% that accounted for 41.03% of the male and 11.95% of the female. Any significant differences didn’t found in the education level, exercise and physical activity between two groups (p>0.05). However, there was a significant difference in the age just in the male group (p=0.043). It found that the prediabetic participants experience visceral fat, BMI, WC, and WHR higher than the normal participants (p=0.037, p=0.010, p=0.000, and p=0.002, respectively) just in the female group. Conclusions: It has been concluded that anthropomorphic and body composition have differences between normal and prediabetes participants; therefore, they may be used as the screening programs. Moreover, it has been suggested that prediabetes can be prevented by controlling anthropometric and body composition indices by exercise.

Background : Volleyball is known as sport that requires high physical fitness, including muscle power, agility and reaction; hence, body composition and anthropometric features play important roles in this field. The purpose of this study was to investigate the relationship between anthropometric and body composition indices with lower limb explosive power in female volleyball players. Material and method : This correlational study was conducted in which 16 semi-professional female volleyball players with an average age of 20.4 ± 1.34 years and BMI of 22.09 ± 3.42 kg/m2 voluntarily participated. All volleyball players had a history of participation in the Tehran province volleyball league. First, data were collected and recorded by demographic questionnaire. Then, the body composition (fat percentage, muscle mass, visceral fat) was measured and recorded in the 3-hours fasting condition by body analysis device (OMRUN Bf511). Finally, Sargent Vertical Jump Test was used to evaluate explosive power of the lower limb muscles. Results :  Pearson correlation coefficient was used at the significant level p Conclusion: The results of this study show that resistance training along with volleyball specific power training can increase the muscle mass as well as it is at the same time.
