Mirzaei B, Curby DG, Barbas I, Lotfi N. Anthropometric and physical fitness traits of four-time World GrecoRoman wrestling champion in relation to national norms: A case study. J. Hum. Sport Exerc. Vol. 6, No. 2, pp. 406-413, 2011. The purpose of the present investigation was to describe the anthropometric and physical fitness traits of a four-time World senior Greco-Roman wrestling champion (age: 24 years, height: 167 cm, weight: 61 kg) in relation to national norms. The anthropometric traits included body weight, height, sitting height, arm-span, and the physical fitness traits included flexibility (sit-and-reach, trunk-and-neck extension and shoulder-and-wrist elevation tests), maximal oxygen uptake (Gas analysis method), muscular endurance (pull-ups and bent-knee sit-ups), muscular strength (bench press, squat), agility (4×9 m shuttle run), speed (40-yd sprint), bilateral visual reaction time and body composition. The major results are as follows: body fat (%): 8.4; body weight (kg): 61; height (cm): 167; sitting height (cm): 89; arm-span (cm): 174; sit-and-reach (cm): 45; trunk-and-neck extension (cm/cm): 0.64; shoulder-and-wrist elevation (cm/cm): 0.54; maximal oxygen uptake (ml·kg -1 ·min -1 ): 56; pull-ups (reps): 50; bent-knee sit-ups (reps/min): 77; agility (s): 7.6; speed (s): 4.57; bilateral visual reaction time (ms): 229; 1RM weight lifted in the bench press relative to body weight (kg·kg -1 ): 1.39 and 1 RM weight lifted in the squat relative to body weight (kg·kg -1 ): 1.83. The present study indicated that measures of the squat, speed and agility tests of the subject were higher than Iranian national norms for 55 kg senior Greco-Roman style wrestling. The measures of bench press and trunk and shoulder flexibility tests were lower than the national norms. In other tests, no major difference was observed between the results of the subject's tests and national norms.

This study was conducted to determine the anthropometric profile of selected national athletes. The purpose of this study was to find out anthropometric measurements, body composition and somatotyping of Iranian cross-country runners. The participants were 9 male national Iranian cross-country runners. The age of athletes was between 20 to 32 years. Cross-country personal best 36min 55s (47s); training volume: 120-180 km.wk; All subjects were assessed for height, weight, breadths, lengths, girths and skinfold thickness. Percentage of body fat was calculated from the sum of 7 measurements of skin-fold thickness. The somatotype and height to weight ratio (HWR) as well as the skin-folds extremity to trunk ratio (E:T) were also calculated. The Mean ( 73), respectively. National Iranian cross-country runners seem to have mesomorph and ectomorph are equal (or do not differ by more than one-half unit), and endomorph is smaller. Despite population comparisons would be required to identify any connection between specific anthropometric dimensions, these reference data reported in the present study for useful to practitioners and researchers, carry immense practical application and should be useful for future investigation on endurance runners selection, talent identification in cross-country running and training program development.

Abstract.Aim: This study investigated the association between motor performance and somatic type, anthropometric, body composition, physiologic and physical fitness profile in young wrestlers. Material: 16 young wrestlers aging 16-19 with a 4-year-experience of taking part in national championships were selected for the study. Following the standard methods in the testing center of Alborz province some tests like aerobic power, muscular endurance, flexibility and agility speed tests and 1RM were taken to integrate the participants. Also, it should be noted that the participants' height, weight, the girth of thigh, elbow, calf and arm and skin thickness were measured. Conclusion:As the present study illustrates, Somatotype of the Endomorphs, Mesomorphs and Ectomorphs were the same. As a result, coaches can plan wrestlers' training programs and review of techniques based on anthropometric and physiologic data driven from their sports performances.Besides, wrestlers could be wellinformed about their performance. Moreover, aforesaid information could be beneficial to wrestling federations and all other organizations contributing the wrestling federation while holding talent identification programs and recognizing young wrestlers.

Background:Sleep is considered as one of the most important factors, directly influencing mental and physical health components. In the last decade, low sleep quality - i.e. poor sleep - has become one of the major problems of the individuals, especially in middle-aged women. Low quality sleep also directly influences memory, functional components, nutrition, and mood.Objectives:This study aims to detect the effect of selected aerobic exercises on sleep quality in non-athlete middle-aged women.Materials and Methods:Fifteen non-athlete middle-aged women participated in this study, all of them suffered from insomnia. Pittsburgh questionnaire was used for determining sleep quality in this sample. Four indices including sleep duration, sleep disturbance, sleep latency, and sleep efficiency have been investigated through this. The period of exercises included eight weeks, three one-hour sessions each week. The sample group was trained during eight weeks through performance of selected aerobic exercises including three groups: sequential movements equip mental movement and movements on the pad. The selected protocol included performance of exercises: 10 minutes for warm up, 10 minutes for sequential movements, 20 minutes for movements by using equipment, 15 minutes for movements performed on the pad, and 5 minutes for cooling down. The exercises during the first four weeks have been presented with 60% increase of the heart rate, and 75% increase during the second four weeks. The sample group was provided with Pittsburgh questionnaire at the beginning of the exercises and the end of each week. The information of each person was registered.Results:The results showed that the mean of sleep duration, sleep disturbance, sleep latency, and sleep efficiency indices significantly reduced 32%, 22%, 30%, 14% and 36%, respectively. The results also showed that the trend of changes in sleep duration, sleep disturbance, sleep latency, and sleep efficiency indices had significant descending trend.Conclusions:We concluded that eight weeks of aerobic exercises can significantly increase sleep quality in middle-aged women.

Purpose: The aim of this study was to compare the effect of resistance exercise with three different methods on integrated electromyography (IEMG) and metabolic responses in recreational athletes.Methods: Twenty four males (mean 23.59±0.87 years) were randomly assigned to three experimental groups. Participants performed knee extension exercises: Slow (SL: 3-3, 3s for each concentric and eccentric action with 50% of 1 RM), Normal (NH: 1-1, 1 s for each concentric and eccentric action 80% of 1 RM) and Traditional (TH: 2-4, 2s for concentric and 4s for eccentric action with 80% of 1 RM). Plasma lactate, glucose and triglyceride concentration and IEMG was measured before and immediately after performing four sets of resistance exercise. Results: Each method significantly decreased IEMG (P<0.05), but there was no significant difference between groups. Lactate was increased following TH and NH more than SL method (P<0.05). Each method significantly increased plasma glucose (P<0.05). Work considering time under tension (work TUT ) was higher (P<0.05) during TH method than the other methods and during SL it was higher than NH method (P<0.05). Volume load was higher (P<0.05) during NH than the other two methods and during TH it was higher than SL method (P<0.05). Conclusion:These results indicate that exercise intensity during the resistance exercise is important for the enhancement of lactate responses, but the slow resistance exercise method could induce acute neuromuscular response as much as high intensity methods. It seems that this method will be advantageous for those who want to increase acute neuromuscular changes with low exercise intensity and volume.
