PurposeTo determine the intra-tester reliability of clinical measurements that assess five components related to core stability: strength, endurance, flexibility, motor control, and function.MethodsParticipants were 15 college-aged males who had not suffered any orthopedic injury in the past year. Core strength measurements included eight isometric tests and a sit-up test. The four core endurance tests were the trunk flexor test, trunk extensor test, and bilateral side bridge tests. Flexibility tests included the sit-and-reach test and active range of the trunk and hip joint motions. Proprioception via passive reposition tests of the hips and a single limb balance test on an unsteady platform were used to evaluate core motor control. Functional measurements consisted of a squat test and a single leg hop test for time and distance. Measurements were performed during two data collection sessions with a week's rest between the sessions. Intra-class correlation coefficients were calculated to establish reliability.ResultsThe overall intra-rater reliability for all core stability related measurements ranged from low (ICC = 0.35, left hip reposition) to very high (ICC = 0.98, sit-and-reach). As a group, the core endurance tests were observed to be the most reliable.ConclusionThere are highly reliable tests in each of the five groups. Overall, core endurance tests are the most reliable measurements, followed by the flexibility, strength, neuromuscular control, and functional tests, respectively. 相似文献

Abstract The purpose of this study was to examine the Southern California Perceptual Motor Tests (SCPMT) since (1) the validity of the tests has been questioned and (2) the tests are widely used in the development of Individualized Education Programs for children with special motoric needs. The subjects were 386 children characterized as having learning and/or perceptual problems; they were evaluated by occupational therapists in Ohio and Tennessee. A factor analysis was made based on the subjects' performances on the 42 individual items. The results indicated that the test items generally have good discriminative ability. However, the distribution of items of some of the individual tests across more than one factor suggests that, at least in children with learning disorders, the tests are sampling a wider number of constructs than was intended in their design. 相似文献

Differentiation is made relative to repeated and multiple measure analyses. A flowchart is provided to help the researcher determine the appropriate analysis for the design of interest. Conservative tests and a multivariate approach are suggested for repeated measures designs. For designs with multiple dependent measures, the following suggestions are provided: rank reduction, Bonferroni approach, and MANOVA. Post hoc tests are also suggested once a significant multivariate F is obtained. The post hoc tests are univariate F tests, two-group breakdown, simultaneous confidence intervals, discriminant analysis, step-down analysis, and contrasts on the classification variable. It is suggested that inclusion of these more appropriate analyses will increase the internal validity of research published in the Research Quarterly. 相似文献

为探讨不同生源的大学新生的体质状况,以3 653名大学一年级学生为研究对象,采用实验测试法按照《国家学生体质健康标准》的要求进行测试研究。结果发现:①城镇生源的大学新生在身高、体重等测试项目上显著性大于农村生源的大学新生(P<0.05),而农村生源的大学新生在耐力项目得分、坐位体前屈、立定跳远和总得分等测试项目上非常显著高于城镇生源的大学新生(P<0.01)。②城镇生源的大学新生中女性同学在肺活量测试项目非常显著大于农村生源大学生(P<0.01),而在800m测试、坐位体前屈、立定跳远和总得分等方面农村生源的女性新生显著高于城镇生源的女性新生(P<0.01)。③城镇生源的大学新生中男性在身高、体重、肺活量等测试项目非常显著高于农村生源的男性(P<0.01),而在1 000m测试、坐位体前屈和总得分等测试项目农村生源的男性新生非常显著高于城镇生源的男性新生(P<0.01)。结论:农村生源大学新生的体质显著性好于城镇生源大学新生,但城市生源大学新生的身高、体重的显著性高于农村生源大学新生。生活的环境、应试教育和对困难的认知能力是造成此结果的主要因素。 相似文献

The findings of this study are summarized as follows: 1. To obtain a reliable pull-up score for male subjects, it is necessary to administer the test on two days and use the mean of the two scores. For female subjects, a reliable score may be obtained by administering the test once. 2. The test scores are weight-dependent for both sexes, but particularly for the older females. 3. The test is far superior to the pull-up and flexed-arm hang tests in regard to the zero-score problem. Zero scores are virtually eliminated with the modified pull-up test. In conclusion, the NCYFS II Modified Pull-up Test has two weaknesses--reliability for male subjects and weight dependency. The test, however, seems to be less weight dependent than the pull-ups or flexed-arm hang tests and virtually eliminates the zero-score problem. It therefore seems to be the most desirable of the tests of upper body strength currently in use. Further research regarding the validity of the test is recommended. 相似文献

ABSTRACT The aims of the present study were to provide an in-depth comparison of inter-limb asymmetry and determine how consistently asymmetry favours the same limb during different vertical jump tests. Eighteen elite female under-17 soccer players conducted unilateral squat jumps (SJ), countermovement jumps (CMJ) and drop jumps (DJ) on a portable force platform, with jump height, peak force, concentric impulse and peak power as common metrics across tests. For the magnitude of asymmetry, concentric impulse was significantly greater during the SJ test compared to CMJ (p = 0.019) and DJ (p = 0.003). No other significant differences in magnitude were present. For the direction of asymmetry, Kappa coefficients revealed fair to substantial levels of agreement between the SJ and CMJ (Kappa = 0.35 to 0.61) tests, but only slight to fair levels of agreement between the SJ and DJ (Kappa = ?0.26 to 0.18) and CMJ and DJ (Kappa = ?0.13 to 0.26) tests. These results highlight that the mean asymmetry value may be a poor indicator of true variability of between-limb differences in healthy athletes. The direction of asymmetry may provide a useful monitoring tool for practitioners in healthy athletes, when no obvious between-limb deficit exists. 相似文献
