Introduction: Studies on the anthropometric characteristics of athletes have a long history, but there are no published reviews on the somatotype of artistic gymnasts. Practitioners and professional coaches can gain guidance from improved understanding of the ideal body constitution and the impact of high-intensity training since preadolescence on body build. The present review is designed to provide this information., Evidence Acquisition: Academic Search Complete, SPORTDiscus, Medline, Google Scholar, and ResearchGate were searched in January 2017. All studies on the body composition of male artistic gymnasts were included. We identified 19 studies assessing somatotype in male gymnasts., Evidence Synthesis: We found high heterogeneity of somatotype components between younger gymnasts (≤18 years) and older gymnasts (>18 years) (1.6±0.3, 5.4±0.8, 3.0±0.6 vs. 1.8±0.4, 5.9±0.6, 2.2±0.4). Four different somatotypes resulted from the literature analysis, and ectomorphic mesomorph was the prevalent somatotype in both younger and older athletes. The main result showed a significant difference in ectomorphy (lower in older gymnasts than in younger gymnasts)., Conclusions: Proper interpretation of the literature data may inform future research and enable professional coaches to longitudinally monitor gymnasts' somatotype components during growth and in talent identification. More research is needed to better understand the most suitable somatotype variations related to the different apparatuses used in artistic gymnastics.

Background: Negative lifestyle factors affect health outcomes adversely. The aim of the study was to assess body composition parameters and their relationship to several lifestyle behaviors among young Italian adults., Methods: A cross-sectional study was carried out on a sample of university students (N.=200; 50% males; 21.9±2.0 years). Anthropometric and bio-impedance traits were directly measured. Behavioral data (physical activity, alcohol consumption and smoking data) were collected by a self-administered questionnaire. Quantitative and qualitative data were used to characterize and compare across participants by univariate and multivariate analyses., Results: The prevalence of subjects at risk (above the cut-points) was 3% in men and 2% in women for generalized obesity (BMI); 1% in women for centralized obesity (waist circumference); 12% in men and 5% in women for obesity (fat percentage). Unhealthy behaviors were infrequent in our sample. Multiple linear regression analyses showed that percentage of fat mass and fat-free mass were closely related to sex and structured physical activity: fat percentage decreased and fat free mass increased with the increasing of sport practice., Conclusions: Our findings highlight new evidence on the particular impact of structured physical activity on body composition in young adults. Interventions should focus on the optimization of youth health behaviors.

Background: The aims of the present study were to assess competitive sprinters' body size and composition and to determine their impact on performance., Methods: Ninety-eight competitive male sprinters (100 m) participated in this cross-sectional study. A series of measurements was directly taken and data on muscular strength and power tests were self-reported. Body composition was assessed by skinfold method and somatotype was calculated by the Heath-Carter anthropometric method. Sprinters were classified into three groups depending on their personal best time and comparisons were performed between the athletes in the top and in the bottom tertiles. Relationships between anthropometric traits and performance were assessed by Pearson's correlation coefficients., Results: Top sprinters had significantly greater body mass index, relaxed and contracted upper arm girths, thigh and calf girths, fat free mass and fat free mass index, and lower ectomorphy than the lowest tertile. Strength and power were significantly higher. Personal best time was significantly correlated with several anthropometric traits and indices of lean body mass., Conclusions: Body size, composition and somatotype differ between performance levels in speed running. Being less ectomorphic, with a greater fat free mass and strength, can explain significant differences in sprinting performances. The results presented in this study provide a point of reference about sprinter characteristics, which can help coaches and sport scientists to improve sprinter performance.

Background: The purpose of the present study was to examine the importance of the somatometric components of elite male and female volleyball players in relation to their different game roles and levels of performance., Methods: Two hundred and thirty-four male athletes (aged 24.7+/-4.4 years) and 244 female athletes (aged 23.1+/-4.4 years) from the Italian A1 and A2 volleyball leagues underwent anthropometric measurements during the 1992-1993 and 1993-1994 seasons. Somatotypes were estimated with the Heath-Carter method., Results: Marked sexual dimorphism in somatotype was observed in the total sample. The average somatotype for men was 2.2-4.2-3.2 (SD 0.7-0.9-0.9), and for women it was 3.0-3.3-2.9 (SD 0.8-1.0-0.9). The somatotype was significantly different in players at different levels of performance (A1 vs A2 leagues), as it follows: 2.1-4.1-3.3 (SD 0.6-0.8-0.7) vs 2.3-4.3-3.0 (SD 0.7-1.0-0.8) in males; 2.9-3.1-3.0 (SD 0.8-1.0-0.9) vs 3.1-3.5-2.7 (SD 0.8-0.9-0.8) in females. The somatotype was also significantly different in players in different roles. In male sex the mean somatotypes for setters were 2.4-4.5-2.8 (SD 0.7-0.9-0.8), for centres they were 2.0-4.0-3.5 (SD 0.6-1.0-0.8), for spikers they were 2.2-4.3-3.0 (SD 0.6-0.9-0.7), for opposites they were 2.2-4.3-3.1 (SD 0.6-0.9-0.8). In female sex the mean somatotypes for setters were 3.1-3.6-2.5 (SD 0.8-1.0-1.0), for centres they were 2.8-3.1-3.1 (SD 0.8-0.9-0.7), for spikers they were 3.0-3.5-2.8 (SD 0.9-1.0-0.9) and for opposites they were 3.0-3.2-3.0 (SD 0.7-0.9-0.8)., Conclusions: The physique of athletes in the A1 league is characterized by higher ectomorphy and lower endomorphy and mesomorphy. There is also a slight tendency of male players to a greater homogeneity in somatotype within the group at the maximum level of performance. Moreover somatotype differs in relation to game role in volleyball players of both sexes: the mesomorphic component is maximal in setters, while the ectomorphic component is maximal in centres.

Somatotypes of 1593 young Italian sport participants (717 males and 876 females) were described and analyzed. The average somatotype for sport participants was 2.7-4.7-2.7 for males and 3.6-3.7-2.8 for females. The predominance of mesomorphy on the other two components was found in all sport-groups examined. This was particularly evident in males for gymnasts and rowers and in females for martial arts competitors. As for sexual dimorphism, females were endo-mesomorphs, while males were balanced mesomorphs. Somatotypes show statistically significant changes with the level of performance in some sport-groups with an increase in the mesomorphic component (in ballgames and martial arts) and in the endomorphic component (in swimming). Comparisons with other sport-groups from literature were greatly limited by several genetic and environmental factors.

Body composition of 1815 North-Italian young sports participants in relation to sex, age, sport and level of performance was investigated. About thickness and anatomical distribution of subcutaneous fat females showed skinfolds thicker than males. Significant differences were observed in skinfold thicknesses means of different sport-groups. Subscapular and forearm skinfolds were the best discriminant variables for males and females respectively. Body density was estimated according to Katch and McArdle (1973) and Durnin and Womersley (1974) equations. Males showed higher body density and lower fat percentage values than females. The lowest value of body density and the highest fat percentage were in male martial art competitors and in females practising skating and athletics. The highest values of body density and the lowest of fat percentage were in males practising athletics and rowing and in female martial art competitors. Highest and lowest values of fat-free mass were in games players and in soccer players and gymnasts respectively. "High aptitude" subjects showed higher fat-free mass values than "middle aptitude" group, besides a tendency towards higher body density values and lower fat percentage than "middle aptitude" group. With aging body density decreased whereas fat percentage and fat-free mass increased.
