RELIABILITY OF FOUR STRENGTH TESTS APPLIED TO GROWING BOYS AND GIRLS / 体力科学

ABSTRACT

Boys and girls of elementary school (1 st, 3 rd and 6 th-grades), junior high school (2 nd-grade) and senior high school (2 nd-grade) were tested for 2 days to examine the reliability of grip strength, back strength, arm strength and leg strength.<BR>The following results were obtained<BR>1. When elementary school boys performed three trials of these four items, over half boys recorded maximal value up to the second trial.<BR>2. The reliability of tests applied to the left and right sides (grip strength, arm strength and leg strength) was not different each other.<BR>3. In boys and girls attending elementary, junior- and senior high schools the reliability of grip strength was highest and the next was back strength.<BR>4. Grip strength had statistically significant relationship to the other three items. Thus grip strength is considered to be the representative of four strength tests for growing boys and girls.
