The results show that the overall quality as the body strength, lower limb explosive power and muscle endurance of the junior school boys who are nourished is better than other groups. Compared with the group of the thin girls, the nourished junior school girls have significant difference in waist power but have no significant differences in the lower limb explosive power and muscle endurance （P 〉 0.05）, and the general condition is better than the other groups. There is no doubt that good nutrition is a guarantee of improving the physical qualities. It is worth mentioning that schools and the related departments should pay more attention to the proper nutrition structure of the students to improve the physical quality of junior school students, to prevent the phenomenon of obesity or to reduce it.
