皮划艇运动员膳食营养调查与评价

经连续五天称重法进行的膳食营养调查发现，我省皮划艇运动员（男性）以膳食中实际获得的营养素跟供给量标准比较，总热量与各营养素的摄入量除维生素Ａ不足（仅占标准的７８．１％）外，其余均超标；三大热能营养素的比例不尽合理（蛋白质２０６．９克，脂肪１７１．５克，碳水化物７０２克分别占总热量的１６％、２９．８％和５４．２％），脂肪量偏高，碳水化合物相对不足。建议在食谱中增加主食、减少脂肪，同时补充维生素Ａ，从而保证皮划艇运动员能得到合理的营养。

The role of sports as a social status determinant for children.

This study was designed to examine children's attitudes toward the role of sports in determining social status, as well as the activities in which children prefer to participate. A total of 227 boys and 251 girls in Grades 4, 5, and 6 completed a questionnaire to determine which criteria were most important in determining personal, female, and male popularity. Personal popularity was answered by the girls and boys according to "what would make you well liked by your classmates." Female and male popularity was determined by asking both girls and boys to decide "what would make (girls, for female subjects, and boys, for male subjects) well liked by your classmates." A comparison of results from the Buchanan, Blankenbaker, and Cotten (1976) investigation and the present study indicated that, in the last 15 years, appearance has become more important and academic achievement less important in determining personal popularity for girls. For boys, the comparison revealed that sports have become more important and academic achievement less important in determining personal popularity. Boys reported sports to be the most important determinant of personal and male popularity and appearance as the most important determinant of female popularity. Sports and appearance became more important for boys with each higher grade level. Girls reported appearance to be the most important determinant of personal, male, and female popularity. For girls, appearance became more important with each higher grade level. A comparison of results from the Buchanan et al. (1976) and the present study indicated that the activities in which girls and boys preferred to participate have changed.(ABSTRACT TRUNCATED AT 250 WORDS)
