Objective: The purpose of this study was to examine the test-retest reliability and the criterion validity of a curlup test (CUT) as a measure of core stability, core endurance and dynamic stability in kindergarten children. CUT performance was also compared to half hold lying test (HHLT) and walking time on course (WTC) among without obstacle, with low obstacle and high obstacle measures of core stability, core endurance and dynamic stability. Methods: To estimate reliability, 33 males and 27 female kindergarten children (M aged=4.5 years old) performed the CUT on 2 different days. In the validity phase of the study, scores of all participants were obtained on three field test measures of core stability, core endurance and dynamic stability (CUT, HHLT and WTC). Results: Results indicate that the MCU test has no significant correlation on intra-class test-retest reliability (R=0.13, p>0.01). The criterion validity of the CUT for kindergarten children has is comparable to that of the HHLT(r=0.98, p<0.01) and WTC without obstacle(r=0.96, p<0.01), with low obstacle (r=0.96, p<0.01) and with high obstacle (r=0.98, p<0.01). Result indicates that the CUT test cannot produces reasonably accurate and stable measures of core stability, core endurance and dynamic stability. Conclusion: These preliminary findings provide evidences into the CUT test cannot produces reasonably accurate and stable measures of core stability, core endurance and dynamic stability for kindergarten children.
