Objectivity, Reliability, and Validity of the Basketball. Throw Test as a Health-related Measure of Upper-Body Muscular Strength in a Sample of Algerian Primary School Children
MEASUREMENT IN PHYSICAL EDUCATION AND EXERCISE SCIENCE(2023)
摘要
This study investigated the objectivity, reliability, and the validity of the Basketball Throw Test (BTT) as an upper-body muscular strength measure. Participants (33 boys and 32 girls; mean age = 8.75 +/- 1.47) performed the BTT on 2 occasions (1-week apart), and the hand-grip test as criterion measure. The objectivity and reliability were estimated using an intraclass correlation coefficient (ICC2,1) and graphically examined according to the Bland-Altman approach. Pearson correlation coefficient and the known-differences method was employed to determine validity. The BTT demonstrated high objectivity ICC2,1 = 0.90 (95% CI, 0.84-0.94), reliability ICC2,1 = 0.91 (95% CI, 0.86-0.95) and validity (r = 0.77, p <.001). The Bland-Altman method graphically confirmed intraclass correlation data. The significant difference in the BTT scores between 6-year-old children (1.61 +/- 0.23) and 10-year-old children (t = -12.64, p < .001) provided additional support of validity. The BTT test is a feasible measure of upper-body muscular strength in school-aged children.
