Abstract Measurements of the field of motion perception of basketball players and non-basketball players were compared. Also, five basketball skill test items were administered to 101 college men, and their scores on these items and the measurements of the fields of motion perception were compared with subjectively-determined basketball ability rating scores. Measurements of the field of motion perception showed an identifiable relationship with basketball ability and, when combined with basketball test items, made a substantial contribution to the forecasting efficiency of the battery. 相似文献

Abstract This study investigated the relationships among student achievement, student engagement, and the selected student characteristics of initial skill, previous experience, and sex. Students (n = 45 after attrition) were pretested, received instruction, and were posttested on the breaststroke. The four instructional periods were videotaped. Videotapes were coded for the amount of time students spent in motor engagement, cognitive engagement, and three nonengaged categories. When all students were grouped together, no engagement variable was a significant predictor of residualized achievement. However, when the analysis was performed for students divided by gender, previous experience, and three levels of initial skill, significant relationships were found. Motor engagement did not predict achievement for the subgroup classifications. Cognitive engagement had a negative relationship with residualized posttest scores for two subpopulation groups. All engaged lime had both positive and negative part correlations with achievement. 相似文献

This study investigated the effects of goal setting in teacher-led group conferences on achievement in archery. University undergraduates enrolled in three beginning archery classes (N = 30) were randomly assigned to two treatment groups—group conference with goal setting and group conferences only. For 10 weeks, subjects met twice a week for archery instruction and once a week with the instructor for a 10-minute conference. Subjects in the goal-setting conference group were directed to set numerical and verbal goals using a printed goal-setting form. Three achievement tests were administered while subjects were shooting from a distance of 20 yards: an initial test during week 1, a progress test during week 6, and a final test during week 10. Analysis of the data indicated that when groups were adjusted for initial differences, the goal-setting group achieved significantly higher scores in archery than the non-goal-setting group (F = 5.31, p < .05). Motivational implications of goal setting procedures are discussed. 相似文献

The purposes of this study were to: (a) examine differences within specific kinematic variables and ball velocity associated with developmental component levels of step and trunk action (Roberton & Halverson, 1984), and (b) if the differences in kinematic variables were significantly associated with the differences in component levels, determine potential kinematic constraints associated with skilled throwing acquisition. Results indicated stride length (69.3%) and time from stride foot contact to ball release (39.7%) provided substantial contributions to ball velocity (p < .001). All trunk kinematic measures increased significantly with increasing component levels (p < .001). Results suggest that trunk linear and rotational velocities, degree of trunk tilt, time from stride foot contact to ball release, and ball velocity represented potential control parameters and, therefore, constraints on overarm throwing acquisition. 相似文献

Recent studies (Chiviacowsky & Wulf, 2002, 2005) have shown that learners prefer to receive feedback after they believe they had a “good” rather than “poor”trial. The present study followed up on this finding and examined whether learning would benefit if individuals received feedback after good relative to poor trials. Participants practiced a task that required them to throw beanbags at a target with their nondominant arm. Vision was prevented during and after the throws. All participants received knowledge of results (KR) on three trials in each 6-trial block. While one group (KR good) received KR for the three most effective trials in each block, another (KR poor) received feedback for the three least effective trials in each block. There were no group differences in practice. However, the KR good group showed learning advantages on a delayed retention test (without KR). These results demonstrated that learning is facilitated if feedback is provided after good rather than poor trials. The findings are interpreted as evidence for a motivational function of feedback. 相似文献

The protective effects of physical activity and fitness on cardiovascular health have clearly been shown among normally developed children. However, data are currently lacking pertaining to children with developmental coordination disorder (DCD). The purpose of this study was to examine differences in fitness measures, body composition, and physical activity among children with and without DCD. A cross-sectional design was implemented examining 261 children (118 girls, 143 boys) ages 4–12 years (mean age 7.8 ± 1.9 years). Children were categorized as having DCD if they scored less than or equal to the 5th percentile (n = 71) or between the 6th and the 15th percentile (n = 52) on the Movement Assessment Battery for Children (MABC; Henderson & Sugden, 1992). The typically developing children had scores between the 16th and the 50th percentile (n = 106) or above the 50th percentile (n = 32) on the MABC. The age-related body mass index was used to characterize body composition. Physical fitness was assessed with a 6-min run, 20-m sprint, jump-and-reach test, medicine ball throw, curl-ups, and sit-and-reach test. Physical activity was estimated with a questionnaire. The percentage of overweight and obese children ages 10–12 years were significantly higher in the DCD groups (severe: 50%, moderate: 23.1%) than in the typically developing groups (medium: 5.6%, high: 0%; p < .05). Significant interactions (MABC x Age Group) were found for the fitness tests (p values < .05), except flexibility; whereby specifically, compared to the children in the typically developing groups children in the DCD groups ages 4–6 years achieved significantly worse results for the 20-m sprint, and children of the DCD groups ages 10–12 years achieved significantly worse results for the 6-min run, jump-and-reach test, and medicine ball throw. The study demonstrates poorer performance in fitness tests with high demands on coordination in children with DCD compared to their typically developing peers. Furthermore, the differences in fitness increased with age between children in the DCD groups versus the typically developing groups. 相似文献

Abstract The leg strength of 70 college men was measured in a position designed to involve the power thrust of the major muscle groups used in the vertical jump. The subjects then performed a modified Sargent jump that used no arm snap. Although the reliability of all measures was high, individual differences in the ratio of tested strength to body mass showed only a low and nonsignificant correlation with jumping performance. The results are interpreted to support the hypothesis that strength exerted against a dynamometer involves a different neuromotor pattern than strength exerted by the muscles during a movement. Tables of means, variabilities, and intercorrelations are included in the report. 相似文献

The purpose of this study was to develop a valid and reliable tool for use in assessing motor skills in preschool children in field-based settings. The development of the Children's Activity and Movement in Preschool Study Motor Skills Protocol included evidence of its reliability and validity for use in field-based environments as part of large epidemiological studies. Following pilot work, 297 children (3–5 years old) from 22 preschools were tested using the final version of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and the Test of Gross Motor Development (2nd Edition). Reliability of the Children's Activity and Movement in Preschool Study Motor Skills Protocol and interobserver reliability were determined using intraclass correlation procedures (intraclass correlation coefficients; ANOVA). Concurrent validity was assessed using Pearson correlation coefficients to compare the Children's Activity and Movement in Preschool Study Motor Skills Protocol to the original Test of Gross Motor Development (2nd Edition). Results indicated that test reliability, interobserver reliability, and validity coefficients were all high, generally above R/r = .90. Significant age differences were found. Outcomes indicate that the Children's Activity and Movement in Preschool Study Motor Skills Protocol is an appropriate tool for assessing motor development of 3-, 4-, and 5-year-old children in field-based settings that are consistent with large-scale trials. 相似文献

A central aim of Physical Education (PE) is the promotion of basic motor competencies (“Motorische Basiskompetenzen” [MOBAK]). These are the necessary prerequisites for developing a physically active lifestyle. Valid test instruments are needed for the evaluation of the effect of PE. For this purpose, we developed a test instrument for the assessment of basic motor competencies in first graders. We empirically investigated the construct validity of this MOBAK test instrument in a study (N = 317, M = 7.0 years, girls: n = 173, boys: n = 144). The exploratory factor analysis shows a two factorial structure (locomotion, object control), which is confirmed in a confirmatory factor analysis (CFI = .96, RMSEA = .036, WRMR = .65). In subsequent analyses, we were able to demonstrate that the calculation of a factor sum value for each factor is statistically valid, the factorial structure is the same for boys and girls (χ2 [6] = 6.95, p = .33), and no differential item functioning exists. The MOBAK test instrument is sufficient for the test-theoretical requirements and is thus suitable for the evaluation of the effect of PE. 相似文献
