The purpose of this study was to examine the psychometric properties of child- and teacher-reported curl-up (CU) scores in children ages 10-12 years in both a norm-referenced (NR) and criterion-referenced (CR) framework. Eighty-four children, 36 boys and 48 girls, performed the FITNESSGRAM (Cooper Institute for Aerobics Research, 1992) CU test on 2 days separated by 48-72 hr. Two video cameras were used to record students' CU performances. Two students performed the CU at the same time, with each child's performance recorded by one camera. The test was terminated when the child stopped due to fatigue or after two form errors occurred. Teacher-reported scores were the average of two independent ratings of each video performance, while child-reported scores came from data collected and recorded by the children. Single trial norm-referenced reliability was R = .75 for girls and R = .80 for boys for teacher-reported CU and R = .69 and R = .70 for child-reported CU for girls and boys, respectively. CR reliability was examined using P, proportion of students who consistently passed or failed the test across 2 days, and km, defined as reliability with chance removed. For teacher-reported scores, P = .89 and km = .78 for boys and P = .81 and km = .62 for girls. For child-reported scores, P = .86 and km = .72 for boys, while P = .79 and km = .58 for girls. For teacher-reported data, 39% of boys passed and 50% failed the test on both days, while for girls the percentages were 27% pass and 54% fail. For child-reported data, 64% of boys passed and 22% failed on both days, while 54% of girls passed and 25% failed. NR validity was examined by correlating teacher and child-reported scores. The resultant coefficient was r = .42 (95% CI = .11-.66) for boys and r = .67 (95% CI = .58-.74) for girls. Additionally, child-reported scores were significantly higher than teacher-reported scores. CR validity was examined with a contingency coefficient, and results indicated C = .55 with 44% false master errors for boys and C = .65 with 29% false master errors for girls. The findings of this study suggest that while NR reliability estimates were moderate for teacher-reported scores, single trial estimates suggest that child-reported CU should be viewed with caution. In regard to CR reliability, both teacher-reported and child-reported reliability were moderate. However, there were marked differences between teacher- and child-reported scores, with children reporting higher percentages of students passing and lower percentage of student failing the test when compared with scores reported by teachers. Validity was rather moderate when viewed in either a NR and CR framework. It is suggested that problems with child-reported scores may be due to the need for additional practice or simplification of the testing protocol.  相似文献

The purposes of this study were to examine the test-retest reliability of the PACER 20-m, multistage shuttle run and to examine the equivalence reliability of the mile run/walk and PACER from both a criterion-referenced and norm-referenced framework. All fourth- and fifth-grade children (N = 266) from one public school were administered two trials of the PACER and one trial of the mile run/walk (mean age = 10.5 ± 0.5 years). The percent of boys that passed the PACER (68%) was similar to the percent of boys that passed the mile run/walk (66%); however, the percent of girls that passed the PACER (96%) far exceeded the percent of girls that passed the mile run/walk (65%). Criterion-referenced reliability was estimated with proportion of agreement (Pa) and modified kappa (Kq) using FITNESSGRAM® (Cooper Institute for Aerobics Research, 1992) standards. Pa = .97 (Kq = .94) for girls and Pa = .82 (Kq = .65) for boys. The high level of agreement for girls was found because of the low criterion-referenced standards, which allowed 99 of 104 girls to pass both trials of the PACER. Criterion-referenced equivalence reliability of the mile run/walk and PACER was moderate for boys (Pa = .83, Kq = .65) and low for girls (Pa = .66, Kq = .33). The low level of classification agreement for girls was also explained by the low standards for the PACER for this age group. Thirty-four percent of the girls that passed the PACER failed the mile run/walk. Norm-referenced test-retest reliability of the PACER was estimated with an intraclass correlation (Rxx) from a one-way analysis of variance model. Reliability estimates were high for two trials (Rxx = .89 for boys and Rxx = .89 for girls) and acceptable for one trial (Rxx = .80 for boys and Rxx = .79 for girls). Pearson correlations between the mile run/walk and PACER were moderate (-.59≤r≤-.67). The moderate correlations between the mile run/walk and PACER and the low criterion-referenced...  相似文献

Abstract

The purpose of this study was to determine test–retest reliability for the 1-mile, 3/4-mile, and 1/2-mile distance run/walk tests for children in Grades K—4. Fifty-one intact physical education classes were randomly assigned to one of the three distance run conditions. A total of 1,229 (621 boys, 608 girls) complied the test–retests in the fall (October), with 1,050 of these students (543 boys, 507 girls) repeating the tests in the spring (May). Results indicated that the 1-mile run/walk distance, as recommended for young children in most national test batteries, has acceptable intraclass reliability (.83 < R < .90) for both boys and girls in Grades 3 and 4, has minimal (fall) to acceptable (spring) reliability for Grade 2 students (.70 < R < .83), but is not reliable for children in Grades K and 1 (.34 < R < .56). The 1/2 mile was the only distance meeting minimal reliability standards for boys and girls in Grades K and 1 (.73 < R < .82). Results also indicated that reliability estimates remained fairly stable across gender and age groups from the fall to spring testing periods, with the exception of the noticeably improved values for Grade 2 students on the 1-mile run/walk test. Criterion-referenced reliability (P, percent agreement) was also estimated relative to Physical Best and Fitnessgram run/walk standards. Reliability coefficients for all age group standards were acceptable to high (.70 < P < .95), except for Fitnessgram standards for 5-year-old girls on the 1-mile test for both fall and spring and for 6-year-old boys and girls on the 1-mile test administered in the spring.  相似文献

This study aimed to introduce a technique using computer-assisted image analysis for measuring body segmental angles during a static strength element on parallel bars. Criterion validity and intra-rater reliability of measurements were evaluated using digital photography, skin markers and a gravity-reference goniometer. Twenty male former gymnasts participated in this study. They performed a strength hold element on parallel bars (V-sit) and they were photographed with legs extended and stabilized at the highest possible level. The leg to horizontal, trunk to vertical and arm to vertical angles were calculated and examined for reliability using image-pro software. The leg angle was also examined for its validity, by simultaneously using a Myrin goniometer. The two goniometric techniques indicated high leg angle measurements agreement (R = 0.997, p < 0.001). However, Bland-Altman analysis showed that there was a slight leg angle measurement overrating using image-pro software, especially at smaller angles. The Intra-class Correlation Coefficient (ICC) values were high for leg angle (R = 0.971), trunk angle (R = 0.957) and arm angle (R = 0.945), showing an excellent test-retest agreement. It was ascertained that the measurement of segmental angles during V-sit on parallel bars using digital photography and computer-assisted image analysis can be highly reliable when taken by the same experienced examiner.  相似文献

The purpose of the study was to determine if currently used FITNESSGRAM® cut-off scores for the Back Saver Sit and Reach Test had the best criterion-referenced validity evidence for 6–12 year old children. Secondary analyses of an existing data set focused on the passive straight leg raise and Back Saver Sit and Reach Test flexibility scores of 87 boys and 91 girls. The reliability and validity evidence was determined for Back Saver Sit and Reach Test cut-off scores of 7, 8, 9, and 10 inches for the boys and girls separately. Reliability evidence for passive straight leg raise and all Back Saver Sit and Reach Test cut-off scores was good to excellent. The most valid cut-off scores had the highest proportion of correct decisions associated with sensitivity ≥.67, and false-positive rate ≤.24. Based on moderate validity evidence, the best Back Saver Sit and Reach Test cut-off scores for 6–12 year olds are 8 and 9 inches for boys and girls, respectively. These findings should be cross-validated with other samples.  相似文献

The purpose of the study was to examine the norm-referenced and criterion-referenced reliability and validity of the Back-Saver Sit-and-Reach Test (BSR; Single-Leg Sit-and-Reach; Cooper Institute for Aerobics Research [CIAR], 1999). One hundred seventy-nine elementary school children (87 boys and 92 girls), 6-12 years old participated, with 44 randomly selected participants retested on a second day. The BSR, Modified Schober (MSCH, Low Back Criterion Test), Passive Straight Leg Raise (PSLR, Hamstring Criterion Test), Active Knee Extension, True Lumbar Extension, True Lumbar Flexion, and Double-Leg Sit-And-Reach were administered in random order. Intraclass correlation coefficients (norm-referenced reliability) for the BSR were extremely high (.98-.99) for both boys and girls. Pa and Km (criterion-referenced test-retest reliability) for the right leg was .90 and .80, respectively, for boys; and .91 and .82 for girls, indicating the participants were classified consistently across days. Norm-referenced validity coefficients (Pearson product-moment correlations, r) of the BSR as a measure of hamstring flexibility were moderate for boys (.67 and .68, right and left legs, respectively) and moderately low for girls (.47 and .44, right and left legs). Correlation coefficients of the BSR as a measure of low back flexibility were extremely poor for boys and girls, with coefficients ranging from .003 to .06. Criterion-referenced validity of BSR for hamstring flexibility was low and unacceptable for right and left legs (Km: .48, .58, respectively), for both boys and girls (Km: .40, .22). The BSR appears to be similar to the Double-Leg Sit-and-Reach in that it is a test of hamstring flexibility but not low back. The criterion-referenced standards for both BSR and PSLR should be re-examined and adjusted to provide a better degree of classification agreement between the BSR and the criterion measure (PSLR).  相似文献

ABSTRACT

The global trend in inactivity in children may be related to psychosocial problems. We investigated the cross-sectional association between physical activity (PA) levels and psychosocial functioning in 3.4–7.3-year-old children. Children from the Dutch GECKO birth cohort (N = 898; 51.6% boys) had PA levels assessed objectively by accelerometry (ActiGraph GT3X) for at least three days. Linear regression analysis was used for associations with psychosocial functioning (parent report of the Strengths and Difficulties Questionnaire), controlling for gender, age and socio-economic status. Higher total and moderate-to-vigorous PA levels (MVPA) were associated with higher Total Difficulty scores, and sedentary time to lower Total Difficulty scores. More time spent in MVPA was significantly associated to “hyperactivity/inattention” in both boys (Standardized BBOYS = 0.192) and girls (Std.BGIRLS = 0.139) whereas for the time in sedentary behaviour, a reverse association was found only in boys (Std.BBOYS = ?0.230). In boys only, more time in MVPA (Std.BBOYS = 0.154) and less time in sedentary behaviour (Std.BBOYS = ?0.147), were significant determinants for ‘behavioural problems’. When using objectively measured PA, parents report more hyperactivity/inattention and behavioural problems in the more active children, and less in the more sedentary children, most clearly for boys. High levels of PA might be an indicator of psychosocial problems in young children.  相似文献

BackgroundPuberty is a critical time in the development of overweight and obesity. The aim of this study was to examine relationships between measures of adiposity, cardiovascular fitness, and biomarkers of cardiovascular disease risk in adolescents.MethodsIn a cross-sectional study design, 129 girls and 95 boys aged 12.9–14.4 years at various stages of puberty were included, along with their mothers (n = 217) and fathers (n = 207). Anthropometric assessments of adiposity were made, along with cardiovascular physical fitness, using the 20-m shuttle run test, and biomarkers associated with cardiovascular risk, including glucose, insulin, triglyceride, fibrinogen, and C-reactive protein (CRP) concentrations.ResultsWaist-to-height ratio values were similar in boys and girls and correlated positively with diastolic blood pressure, insulin, triglyceride, fibrinogen, and CRP concentrations, and inversely with cardiovascular fitness scores. Skinfold thickness measurements were higher in girls. High-molecular-weight adiponectin concentrations were lower in boys than girls, particularly in late puberty, and CRP levels were higher. Cardiovascular fitness, maternal body mass index (BMI), and paternal BMI contributed independently to the variance in waist measurements in girls and boys. Gender, triceps skinfold thickness, and weight-to-height ratio, but not parental BMI, contributed independently to the variance in cardiovascular fitness.ConclusionThere is a relationship between measures of adolescent adiposity and parental weight that involves factors other than cardiovascular fitness. Adolescent boys have relatively more abdominal fat than girls and a tendency to have a proinflammatory profile of biomarkers. These observations suggest that family and social environmental interventions are best undertaken earlier in childhood, particularly among boys.  相似文献

Abstract

The purpose of this study was to assess the test–retest reliability and criterion validity the Self-Administered Physical Activity Checklist (SAPAC) translated into the Greek language. To evaluate reliability, 72 students (35 girls and 37 boys) of the fifth and sixth grade completed SAPAC on two separate occasions, two weeks apart. Internal consistency was determined with Cronbach alpha coefficient and test–retest reliability with the intraclass correlation coefficient (ICC). To evaluate criterion validity, the RT3 Research Tracker accelerometer was used as standard measure, in 90 randomly selected Greek children (51 girls and 39 boys), aged between 10 and 13. Each subject participated for two consecutive days. On day one, an accelerometer was fitted when school started. On day two, the accelerometers were returned and each subject completed the questionnaire. The internal consistency and the test–retest reliability of SAPAC on total metabolic equivalent (MET) score, MET score of low physical activities (LPA) and MET score of moderate to vigorous physical activities (MVPA) were very satisfactory (all Cronbach's alpha > 0.87, and all ICC > 0.85, P <0.001). The Kendall's tau-b test revealed that the degree of agreement between SAPAC and RT3 accelerometer on total MET score and MET score of MVPA were 0.31 and 0.37, respectively (P <0.01). It was concluded that the Greek translated version of SAPAC is a reliable questionnaire that provides valid estimates of total, as well as moderate to vigorous activities MET scores.  相似文献

This study was designed to examine the reliability of peak finger force during 4-finger curling in a sample of expert level young competitive rock climbers. The participants (N = 31; 16 boys, 15 girls; 13.0 ± 2.7 years of age) completed 2 maximal finger curls with each hand. Finger force was measured via a piezoelectric force sensor fitted with a plate to accept the first digits of the 4 fingers. Force was applied to the plate/sensor by the fingers via a 3-sec maximal contraction. Reliability of the finger curl for each hand was estimated using a one-way repeated measure analysis of variance (ANOVA) and intraclass test-retest correlation. Reliability of the measurement for the left hand was estimated at R = .947 (.95 confidence interval, .891-.975). Reliability for the right hand was estimated at R = .902 (.95 confidence interval, .796-.953). No significant ( p > .05) differences were found between the 2 trials for either hand. Peak force measurement during maximal finger curls using this protocol and population was judged to be reliable.  相似文献

Abstract

The purpose of this study was to compare estimates of test reliability obtained from two sequential testing plans—trials-to-criterion (TTC) and sequential probability ratio (SPR) testing—when reliability is defined as the consistency of classification. Data from a golf chip test given to 110 beginning golf students (n = 80 males; n = 30 females) at the University of Wisconsin were used for analysis. Test specifications for the SPR test were α = β = .05, θ0 =.70, and θ1 = 50. Two mastery levels for the TTC test were examined, .70 and .60, with success criteria ranging from R = 6 to R = 12. For each sequential testing plan, both P and kappa were calculated to estimate reliability. Results for the total group and for gender indicated that reliability was higher with the SPR test when the mastery level was .70, while reliability was similar under both plans at a mastery level of .60. Median test lengths for the group were 21 for the SPR test and an average of 12 across all R values for the TTC test. Misclassification error rates for the TTC test, however, were substantially higher than under the SPR test, particularly for false nonmaster errors. These data suggest that SPR testing would be the preferred approach when misclassification errors are of primary importance, such as to determine minimal competency for certification. However, TTC testing is a viable alternative for classroom tests because of ease of administration and shorter test length.  相似文献

Background: Developmental theorists suggest that physical activity during early childhood promotes fundamental motor skill (FMS) proficiency; and that differences in FMS proficiency are largely related to children's experiences.

Aim: To examine associations between participation in different types of recreation/leisure and FMS proficiency of boys and girls in their first year of school. We hypothesized that there would be positive associations between FMS proficiency and participation in organized sport, physical activities, and active physical recreation; but not for other types of recreation/leisure.

Method: Participants (n?=?74) were kindergarten children (Mage?=?5y11?m; boys?=?55%). Parents completed the diversity dimension of the Children's Assessment of Participation and Enjoyment (CAPE) survey. The CAPE measures children's participation in everyday activities outside of mandated school activities in the past four months in five types of formal and informal activities, specifically: Recreational activities, Physical activities, Social activities, Skill-Based activities, and Self-Improvement activities. Two categories of activities were also reported: Organized Sport and Active Physical Recreation. Locomotor and object control skills were assessed using the Test of Gross Motor Development-2 and static balance was assessed using a stork stand. Sex-based differences in motor skills and participation were examined using chi-squared analyses. Correlation coefficients were used to examine relationships between motor skills and CAPE sub-domains and categories. Linear regression was used to examine whether the type of activity predicted motor skill proficiency and the reverse.

Results: There were no sex-based differences in locomotor skills; whereas boys' object control skill scores were significantly higher than girls, and girls' stork stand scores were higher than boys'. Although there were no sex-based differences in the more active categories of recreational pastimes; girls participated in significantly more formal and informal dance and the prevalence of participation in team sports was significantly higher for boys. For boys, participation in physical activities predicted both locomotor and object control skill scores, organized sport predicted object control skills, and active recreation predicted stork stand times and object control skill scores. These relationships were not evident among the girls.

Conclusions: These findings illustrate that young children participate in a narrower array of physically active recreational pursuits compared with less active pursuits. There were notable sex-based differences in the relationships between participation and motor skill proficiency. For girls, none of the associations between recreational pastimes and motor skill proficiency were significant. This suggests that the motor proficiency of girls, as assessed in this study, is neither a precursor to, nor an outcome of, participation in active recreational pastimes. Contrastingly, the findings for boys support theory that suggests that physical activity is driving the acquisition of particular types of motor skills. Less active recreational activities were not associated with motor skill levels of boys, whereas each of the more active categories of recreational pastimes (active recreation, physical activities, and organized sport) predicted at least one sub-type of motor skill. It also seems clear from our findings that more light needs to be shed on how to optimally portray young girls' motor skill proficiency; as well as the relationships between their participation and motor skills.  相似文献

Different methods have been developed to quantify trunk muscle strength and endurance. However, some important protocol characteristics are still unclear, hindering the selection of the most suitable tests in each specific situation. The aim of this study was to examine the reliability and the relationship between 3 representative tests of the most common type of protocols used to assess trunk muscle strength and endurance. Twenty-seven healthy men performed each test twice spaced 1 month apart.Trunk strength and endurance were evaluated with an isokinetic dynamometer and 2 field tests including Biering-Sørensen test and Flexion–rotation trunk test.

All tests showed a good relative consistency (intraclass correlation coefficient [ICC]> 0.75), except for the isokinetic endurance variables which had low–moderate reliability (0.37 < ICC > 0.65). Absolute reliability seemed slightly better in the isokinetic protocol than in the field tests, which showed about 12% of test–retest score increase. No significant correlations were found between test scores.

After a familiarisation period for the field tests, the 3 protocols can be used to obtain reliable measures of trunk muscle strength and endurance. Based on the correlation analysis, these measures are not related, which highlights the importance of selecting the most suitable trunk test for each situation.  相似文献

In this study the authors examine the test–retest reliability and concurrent validity of the Repeat Ice Skating Test (RIST). This was an on-ice field anaerobic test that measured average peak power and was validated with 3 anaerobic lab tests: (a) vertical jump, (b) the Margaria–Kalamen stair test, and (c) the Wingate Anaerobic Test. The participants (n?=?14) were 11- to 12-year-old males selected from a Peewee “A” level ice hockey team (Thunder Bay, Canada). The results of the test–retest reliability estimation showed that the RIST was a reliable test at measuring average peak power in watts (R = .99, C.I.95% = 0.97 to 0.99) and watts per kilogram (R = .98, C.I.95% = 0.94 to 0.99). The RIST was also a valid test when correlated with the 3 anaerobic lab tests for measuring peak power in watts: vertical jump (r = .86, C.I.95% = 0.72 to 0.94), Margaria–Kalamen stair test (r = .66, C.I.95% = 0.39 to 0.83) and Wingate Anaerobic Test (r = .86, C.I.95% = 0.72 to 0.93). The test is considered promising because it does not require any specific equipment, and is a sport-specific, on-ice test, that can be administered during a regular ice hockey practice session.  相似文献

This study aimed to examine the validity and reliability of an instrument designed to measure student perceptions of curricular goals in physical education, the Curricular Goals in Physical Education Questionnaire. Participants were 879 Finnish students from grades 7 to 9 (412 girls, 467 boys; mean age 13.81). An exploratory factor analysis was performed on Sample 1 (n = 287), revealing a four-factor solution and suggesting that factor structure be cross-validated with confirmatory factor analysis in Sample 2 (n = 592). Confirmatory factor analysis demonstrated an acceptable fit and supported the four-factor model. Tests for gender invariance supported configural, metric, and scalar invariance. Analyses of factor mean differences indicated that girls attributed more importance than boys to physical education’s health-related goals, social and emotional learning, and motor skill development. This study confirmed the validity of the Curricular Goals in Physical Education Questionnaire to assess student perspectives on curricular goals across gender. In order to improve factor structure the authors suggest the addition of an item measuring skill acquisition to future versions of the instrument.  相似文献

The purpose of this study was to examine the validity and reliability of the Cooper 12-min swim test in high school male swimmers ages 13 to 17. Thirty-three boys performed three 12-min swims and 1 maximal graded treadmill test within a 14-day period. One practice swim was conducted 1 week prior to participation in this study. VO2max was assessed by indirect calorimetry with open-circuit spirometry with the Truemax 2400 metabolic cart (Consentius Technologies, Sandy, UT). Test-retest reliability of the 12-min swim assessed via 1-way analysis of variance indicated moderate reliability (R = .66, 95% confidence interval [CI] = .42-.81), whereas concurrent validity assessed via a Pearson product-moment correlation indicated a moderate relation (r = .47, 95% CI = .15-.70, r2 = .22). Results indicate that the Cooper 12-min swimming test is only moderately reliable after 2 practice swims and does not appear to be a valid field test of aerobic capacity in high school male swimmers ages 13 to 17.  相似文献
