A survey was conducted on 107 Exercise Science students at a Midwestern public university. Each student was shown pictures （male and female） of Sheldon＇s three somatotypes （ectomorph, endomorph, and mesomorph） and asked one question about their impression from each photo. A Wilks＇ Lambda distribution concluded at least two of the means for each somatotype group were significantly different. A pairwise comparison analysis was conducted which indicated that all of the group means were different from each other. Upon further examination of the data, a statistical significance was found using a multinomial logistic regression. The researchers＇ hypothesis was confirmed in that there was a difference in opinion regarding students＇ perception on Exercise Science professors＇. In conclusion, this study demonstrates that overweight people are also often perceived as less intelligent, unpopular, and unsuccessful than people of average weight. The findings in this study do support the outcomes of the research from previous investigations.展开更多

The objec- tive of the present paper was to compare: somatotype, body composition and energy availability in female gymnasts students in search for a better sport performance. We evaluated 24 healthy female children aged 7 - 12 years by means of a nutritional and anthropometric examinations, somatotype and body composition calculation, and energy availability measurement. We observed a low consumption of real calories intake, carbohydrates, and low amount of the real body weight mesurements among gymnatics students. Mesomorphic and ectomorfic somatotypes were the more frequent somatotypes found. Moreover, we saw significant differences in body composition and in energy availability among the differente somatotypes in student of gymnastics. Differences were located between endomorphic, mesomorphic, and ectomorphic somatotype groups in body composition while in energy availability were among mesomorphic-ectomorphic, and between endomorphic-ectomorphic groups. In conclusion, our data had important implications for per- formance of gymnastics in students and were discussed here.展开更多
