Standing Broad Jump (SBJ) is a field test used to assess leg power. This study aims to determine the reliability, validity, and develop norm reference among adolescents. The evidence of the reliability, validity, norm need to establish in the particular population to support the interpretation of the scores. This study involved 60 subjects and six raters for reliability and validity. 417 subjects for norm development. The ICC, test-retest, and Pearson Correlation were used to determine the reliability. Independent sample t was used to determine the validity. The standard deviation method was used to construct the norm reference. Findings showed the ICC was high among male raters (.96) and female raters (.99). The consistency of the instrument excellent among males and female subjects (r = 96, r = .90). Independent sample t-test showed t value (58) = 3.395, p = 0.01 was significant. Finding showed a significant difference between the elite (M= 2.0871) and non-elite athlete (M= 1.897) for male. While, there are significant different for female subjects’ t value (58) = 7.324, p = 0.00 was significant. The difference showed the SBJ has the construct validity evidence in this population. This study also indicated new norm for SBJ as (M = superior 2.54 above, F = 2.06 above, excellence, M= 2.26-2.53, F= 1.74-2.05, good, M= 2.97-2.25, F= 1.40-1.73, average, M= 1.69-1.96, F = 1.06-1.39, poor, M= 1.68 and below, F= 1.05 and below). The results suggest that SBJ are reliable and validity with the norm reference to assess leg power. This study also will enhance the quality of Physical Education teacher either local or abroad. Hence, quality teachers should produce pupils with the balance of intellectual, spiritual, emotional, and physical. This study also provides new direction for others researcher to conduct new study especially in term of methodology and population. |
