Background and Aim: Body building sport is probably most dependent to balanced and scientific nutrition. Therefore,the purpose of this study was to design and evaluation of computerized diet programs on the performance andanthropometric parameters in body builders. Materials and Methods: In a semi-experimental study, seven malebodybuilder students were selected. One week of their regular diet analyzed by nutritional evaluation and diet therapysoftware for energy and nutrients. Then, one week balanced diet was designed with the software according to bodybuilders’ dietary and exercise requirements (Energy=3000 kcal, 55-65 percent by carbohydrates, 20-25 percent by fat, 18-20 percent by protein). The effectiveness of the diet was evaluated before and after diet therapy by comparison ofweight, body fat percent, circumferences (waist, hip, arm, thigh and wrist), muscular strength, muscle force, and 24 hurine urea and creatinine concentrations. Daily diet consumption analysis was done by the software. Subjects had theirregular training exercise during both periods (three sessions of weight training per week). To evaluate the effectivenessof balanced diet, dependent t-test was implemented and Pearson's regression also was used to find any relationbetween parameters (p<0.05). Results: The results of this research showed significant increase in the chest, arm, andthigh circumferences as well as standing long jump, vertical jump, hand dynamometry, lift dynamometry, one repetitionmaximum leg press, curl up, and pull-up chest press and a significant decrease in the body fat percent and chestcircumference has seen found (p<0.05). Furthermore, a significant and positive correlation was found between chestand arm circumferences (r=0.80) and between chest and thigh circumferences (r=0.87)(p<0.05). Among functionalparameters, hand grip and lift dynamometer (r=0.75), long and vertical jumps (r=0.82) showed positive correlations.Conclusion: With regard to the results of this research it may conclude that a designed balanced diet in term of energyand macronutrients when considered individual and sporting requirements as well as appropriate training needs is ableto improve body composition, anthropometric parameters and athletic performance without necessary for supplementation.

Background and Aim: The physical fitness, form and the anatomy of the athletes have a significant role for their succession; therefore the present research aimed to describe the anthropometric and physical fitness profile of the Iranian’s national field hockey players. Materials and Methods: 29 players in the Iranian’s national team camp took part in the research voluntarily, with average age of 23.42±3.61 yr., height of 176.8±7.17 cm, weight of 71.62±8.32 kg. This group of players were consisted of four different positions; 4 goalkeepers, 10 defenders, 10 midfielders, and 5 strikers. The anthropometric characteristics including weight,BMI, sitting height, the arms’ length were measured by standard methods. Moreover, the physical fitness factors also were measured by following tests: 36 meters shuttle run, Illinois test, 10 × 20 meter, standing long jump, bending forward, 1600 meters, sit and reach, and Zig Zag jumps test. The statistical analysis was calculated using SPSS v.20 and MS Excel, through which the anthropometric and the physical fitness profile of the players in each position. Results: The BMI of other characteristics of the goalkeepers, defenders,midfielders, and strikers are as follow respectively; 23.11±2.41 kg/m2, 23.11±1.6 kg/m2, 23.21±1.7 kg/m2, 21.71±1 kg/m2; the sitting height 94±4.71 cm, 94.21±5.11 cm, 93.51±4.91 cm, 97.21±3.51 cm; the arms’ length 181.23±6.11 cm, 180.44±8.63 cm, 177.74±8.06 cm, 185.43±7.65 cm; the speed 5.29±0.28 sec, 5.02±0.11 sec, 4.99±0.22 sec, 5.11±0.09 sec; the agility 15.85±0.53 sec, 17.04±0.77 sec, 15.2±0.41 sec, 15.42±0.93 sec; the speed endurance 44.37±0.8 sec, 48.73±1.66 sec, 43.86±0.75 sec, 43.59±0.73 sec; the lower limb power 240.2±15.53 cm, 245.43±14.13 cm, 245.33±16.53 cm, 249.48±9.43 cm; the flexibility 36±5.93 cm, 35.58±5.43 cm, 32.61±7.70 cm, 27.42±10.82 cm; the cardiovascular endurance 392 sec, 357 sec, 342±0.02 sec, 368±0.02 sec; the abdominal muscles endurance 63.76±6.21 no, 61.78±4.35 no, 57.68±4.59 no 56.49±4.84 no; and the lower limb muscles endurance 136.79±10.65 no, 140.32±13.60 no, 142.52±5.50 no, 140.60±10.90 no. Conclusion: The anthropometric characteristics of the Iranian players holding different positions are at favorable level, although they have weaknesses regarding most of the physical fitness parameters.
