Relationships among selected attributes and three measures of upper body strength and endurance in elementary school children.

The purpose of this investigation was to assess (a) proportions of children unable to perform each of three measures of upper body strength and endurance--pull-up, flexed-arm hang, and modified pull-up; (b) relationships among selected attribute variables of age, weight, percent body fat, and body mass index, and the three measures of upper body strength and endurance; and (c) the attribute variables which best predict scores for the three measures of upper body strength and endurance. Subjects were 104 elementary school children in Grades 1 through 6. Percentages of children obtaining zero scores were computed.
