Abstract

In this study, we examined the development of skill competence and tactical knowledge of 41 eighth-grade students (mean age 13.6 years) as they completed a season of badminton conducted following the features of Sport Education. Using data from students’ performance on badminton skills tests, their competence in game play, and their tactical knowledge, it was determined that these students made significant improvements in their ability to not only control the shuttle, but also to hit it more aggressively. This resulted in improvements in both the selection (what shot to make) and execution (ability to produce the desired shot) dimensions of their game play. In addition, the students demonstrated significant improvements in their ability to select tactical solutions and make arguments for those decisions when watching videotaped performances of badminton games. The key explanation for the development of competence in this setting was that the structure of the Sport Education season allowed for significant practice opportunities, and that the authenticity and consequential nature of the game play helped move all but weak novice students from a more cooperative version of net-game play to one where tactical decision making and execution was valued.  相似文献

Abstract

The study was designed to determine the relationships between achievement in reading and achievement in selected motor skills for children in grades 1, 3, 5. The Iowa tests of basic skills were used to determine reading achievement and the Johnson motor achievement battery was employed to measure achievement in selected motor skills. The Pearson product-moment coefficient of correlation was applied to compute the relationships between the reading and motor achievement variables. The subjects were divided into three reading achievement levels and Scheffe's method of comparing pairs of means from a two-way analysis of variance table was employed to determine if the achievement differences in the motor skills tests were significant. The following conclusions were drawn: a) Highly significant correlations were found to exist between achievement in reading and the throw and catch test and achievement in reading and the zig-zag run test; b) Little or no consistent relationship existed between achievement in reading and the kicking test or the jump and reach test; c) Significant differences among the selected reading levels were found for the throw and catch test and the zig-zag run test; d) Few significant differences among the selected reading levels were found for the kicking test and for the jump and reach test.  相似文献

Abstract

According to crisis theorists, people are susceptible to the influence of others during a crisis. In an effort to test this notion, 60 first grade children were given motivational suggestions to enhance their performances on a hand dynamometer during the first three weeks of school. The research design tested the effectiveness of motivational suggestions by comparing performances of 30 subjects who received suggestions to the performances of 30 subjects in a control group. The only significant differences found were in the performances of the subjects who received motivational suggestions. The results did not uphold the notion of crisis theorists, but they did indicate that motivational suggestions were effective in enhancing performance.  相似文献

Purpose: The purpose of this study was to know whether an intervention using an adaptation of the teaching games for understanding approach (named teaching races for understanding [TRfU]) led participants to improve skill execution, decision making, race performance, race involvement, race knowledge, enjoyment, intention to continue practicing sailing, and perceived competence. Method: Participants were 67 children from a randomly selected sailing school (Mage = 9.32 years, SD = 2.60 years) and 2 coaches. We designed and validated the TRfU lessons, and 1 coach was trained in the approach. The TRfU group participated in 11 lessons. This study followed a mixed-methods data approach. Quantitative data were evaluated using a quasiexperimental pretest–posttest design with a control group. The intervention consisted of teaching sailing using the TRfU approach. Children and coaches’ perceptions were evaluated through an interview on completion of the study. Data were collected using an adaptation of the Game Performance Assessment Instrument, a knowledge questionnaire, 2 psychological scales, and interviews with children and coaches. Results: The TRfU group showed statistically significant improvements in skill execution, decision making, and race performance compared with the control group, as well as significant improvements in race involvement, race knowledge, and enjoyment (ES = 0.64–2.63). Conclusion: Teaching races for understanding can be used in sailing to improve students’ capacity to reflect and connect theoretical knowledge with their motor performance in the race.  相似文献

ABSTRACT

Imitation jumps are frequently used in training for ski jumping. Yet, the dynamics of these jumps differ considerably. Thus, the relevance of imitation jumps for ski jumping performance is not elucidated. The aim of this study was to investigate the relationship between the technical execution of imitation jumps and ski jumping performance level. We compared the imitation jumps of 11 ski jumpers of different performance levels using a Spearman correlation transform of time traces of the kinetics (measured using force cells and motion capture) of imitation jumps. The kinetic aspects that were related to performance centred on the moment arm of ground reaction force to the centre of mass before the onset of the push-off, angular momentum early in push-off, thigh angle during the main period of push-off and vertical velocity towards the end of push-off. We propose that the thigh angle may be a key element allowing high development of linear momentum while preparing for appropriate aerodynamic position. Furthermore, the findings suggest that the kinetic development prior to (and during) push-off is more important than the kinematic end state at take-off.  相似文献

Background: Senior secondary physical education courses for certification continue to evolve with curricula reform occurring to ensure content is contemporary, student learning outcomes are maximised and assessment practices are valid for determining certification of students. The content of examinable senior secondary physical education courses privilege theoretical concepts over student physical performance of motor skills and this is reflected in the use of written assessment of cognitive outcomes in many courses internationally.

Purpose: Student examination data were analysed from the year 12 (exit year) written examination of Victorian Certificate of Education (VCE) Physical Education to determine if student performance varied by Area of Study (content). Additionally, it investigated whether there was a relationship between student performance in each of the four Areas of Study examined and overall examination performance and considered the alignment of curriculum, assessment and pedagogy and the implications the findings may have on the teaching of VCE Physical Education in the future.

Methods: A secondary data analysis of student results from the 2011 (n?=?9323; M?=?5212, F?=?4111) and 2012 (n?=?8781; M?=?5011, F?=?3770) VCE Physical Education (Victoria, Australia) examinations were conducted. Examination questions were categorised by content, and means and standard deviations (SD) for discrete and continuous data were calculated, and categorical variables were presented as percentages. Regression analysis was also performed to establish the relationship between student cohort size and examination scores. An independent sample t-test was used to explore the examination scores and each Area of Study scores across 2011 and 2012. A one-way ANOVA were performed to investigate the differences of each Area of Study scores between examination grades from UG to A+.

Results: The results showed a positive correlation between VCE Physical Education student cohort size in a school and examination score in 2011 and 2012. Student performance differed across both years (2011 and 2012) and across Areas of Study within each of the years analysed. Students performed significantly lower on questions relating to the ‘planning, implementing and evaluating a training program’ Area of Study in 8 of the 11 possible grades (2011) and 10 of the possible 11 grades (2012) than in each of the other Areas of Study.

Discussion and conclusions: This study reveals that student performance on the external VCE Physical Education examination is not consistent across all content areas (Areas of Study). This may suggest that student difficulties in answering questions based on content in ‘planning, implementing and evaluating a training program’ result from topic or content difficulty rather than process or question difficulty. From these findings, implications for teaching examinable physical education effectively include the use of experiential learning and practical experiences to provide students with experiences from which they can draw knowledge when completing written assessment tasks. Additionally, the importance of having the required content knowledge to teach examinable physical education confidently for pre-service and in-service teachers is discussed.  相似文献

Abstract

Six groups of subjects were tested to determine if various training programs affected performance in speed in swimming 30 yards. No evidence of improvement was found after one group of subjects had been exposed to absolutely no exercise for six weeks and, also, after a group of subjects had participated in various exercises with weights three times weekly for six weeks. Two groups of swimmers who participated in practicing starts, kicking, arm stroking, and sprinting 30 and 60 yards significantly improved their performances in speed in swimming; one group of subjects followed the preceding program three times weekly and another group used the same routine six times a week. Two other groups, one of which was exposed to weight training and swimming, and one of which was exposed only to 30-yard sprints and practicing starts, both showed statistically significant differences in performance.  相似文献

Abstract

The subjects were 127 boys and 137 girls in grades 4, 5, and 6. Data were collected representing their attitudes toward physical activity, degree of primary involvement in various forms of physical activity, and level of performance in running, jumping, and throwing. Canonical correlation analysis was utilized to examine the nature and degree of the relationships among the children's attitudes, involvement, and proficiency in physical activities. The results suggested a strong relationship between the attitude domain and a combination of the involvement and performance domains; however, there was no common structure to account for the significant canonical relationship between these domains. Further analyses indicated that the basis of this association was the strength of the relationship between the attitude and involvement domains, and that the attitude and performance domains were virtually unrelated. Consideration is given to theoretical and practical implications of these findings.  相似文献

Abstract

The purpose of this study was to determine the coding characteristics of kinesthetic location information acquired during learning trials. Forty-eight blindfolded subjects learned to make a linear response with the right hand to a criterion location during 13 trials. Upon completion of the learning trials, subjects performed 10 trials without knowledge of results (KR) under one of four treatment conditions which were defined by the limb used and the dominant source of feedback available. Specifically, the conditions were right-hand control with kinesthetic feedback, left-hand kinesthetic, right-hand visual, and left-hand visual. The results of the ANOVAs for absolute error (AE) and constant error (CE) from the no-KR trials revealed that the visual feedback groups made significantly greater response errors than did the kinesthetic feedback groups. The blocks main effect for CE was also significant. Analysis of variable error (VE) indicated that the visual feedback groups were significantly more consistent in their responses than were the kinesthetic feedback groups. Within a motor learning paradigm, the concept of a spatial-location coordinate system was supported by the similar performances of the right-handed and left-handed groups. A discrepancy in this system was identified when visual feedback was provided for controlling the response to a location previously learned with kinesthetic cues.  相似文献

Abstract

Eighty randomly selected kindergarten pupils were administered one of four figure-ground variations of a gross motor task in order to determine the effects of the various patterns on the performance of the task. All subjects were administered the figure-ground subtest of the Frostig Developmental Test of Visual Perception and the gross motor task which involved walking in a lateral direction between the rungs of a ladder placed in a horizontal position over a floor pattern. An analysis of variance revealed significant differences in the error-time performance among the groups. Pearson product-moment correlation techniques revealed significant relationships between the gross motor task and the Frostig test.  相似文献

Abstract

Evidence suggests the development of fundamental movement skill (FMS) is a key factor in promoting long-term physical activity. Low levels of activity among preschool children and the relationship between physical activity and the development of fundamental movement skills underline the need to determine the factors associated with children's development of such skills. As parents play an important role in the socialization process, the aim of this study was to examine correlates of family and neighbourhood characteristics as well as parental behaviour and beliefs on FMS performance in 4- to 6-year-old preschool children. Relationships between preschool children's FMS performance and family contextual variables were examined within a sample of 846 preschool children. Results identified positive associations of FMS performance with parental education, father's physical activity, transport to school by bicycle, and the high value placed by parents high on sport-specific aspects of children's physical activity. Variables negatively associated with preschool children's FMS performance included father–child interaction in TV-viewing and reading books, the high importance placed by parents on winning and performance in children's physical activity. Furthermore, the ambiguity of associations between FMS performance and parental beliefs underlined its complexity.  相似文献

The aim of this systematic review is to provide an overview of outcome measures and instruments identified in the literature for examining technical and tactical skills in tennis related to performance levels. Such instruments can be used to identify talent or the specific skill development training needs of particular players. Searches for this review were conducted using the PubMed, Web of Science, and PsycInfo databases. Out of 733 publications identified through these searches, 40 articles were considered relevant and included in this study. They were divided into three categories: (1) technical skills, (2) tactical skills and (3) integrated technical and tactical skills. There was strong evidence that technical skills (ball velocity and to a lesser extent ball accuracy) and tactical skills (decision making, anticipation, tactical knowledge and visual search strategies) differed among players according to their performance levels. However, integrated measurement of these skills is required, because winning a point largely hinges on a tactical decision to perform a particular stroke (i.e., technical execution). Therefore, future research should focus on examining the relationship between these skills and tennis performance and on the development of integrated methods for measuring these skills.  相似文献

Abstract

Utilizing canonical correlation analysis, the multivariate relationship between selected measures of motor performance and intellectual achievement was studied on 91 high school pupils. The students involved in the study were culturally deprived students who had been achieving well below their expected capacity. A significant relationship was found between the intellectual achievement domain and the motor performance domain. Also, significant relationships were found between the intellectual achievement domain and both of the sub-domains of fitness and coordination. The results in the present investigation were compared with the univariate analyses in a previous study. It was concluded that when the degree of relationship between two domains is desired, canonical correlation analysis may be of more value than the usual univariate procedures.  相似文献

Abstract

The purpose of this investigation was to determine whether combining two mental preparation strategies would be more effective in enhancing performances than a single strategy. Subjects (n = 40) practiced on a basketball free throw task (20 shots) using one of the following mental preparation strategies: (a) imagery, (b) relaxation, (c) relaxation plus imagery, (d) placebo control. To simulate game conditions, subjects were allowed only 10 s in which to use their mental preparation strategy. After the practice session, subjects shot 20 test free throws using their designated technique. Results indicated a significant main effect with the imagery group performing significantly better than the placebo control group although there were no specific differences between the three experimental groups. The results are discussed in terms of potential variables mediating the effectiveness of imagery in enhancing sport performance, and future directions for research are offered.  相似文献

Abstract

Effects of movement context upon the encoding of kinesthetic spatial location information were examined in a series of experiments using a motor learning paradigm. A cross-modal, kinesthetic to kinesthetic plus visual feedback procedure was used in each experiment to determine the encoding characteristics of spatial information within a variety of movement conditions. Following knowledge of results trials, subjects performing in cross-modal conditions had significant directional errors (overshooting of the target) for spatial locations associated with specific and non-specific body-referents (Experiment 1), for different movement directions to the same target (Experiment 2), and for long (40 cm) movements (Experiments 2, 3) and short (15 cm) movements (Experiment 4). However, subjects in both intermodal and intramodal conditions who switched movement direction had significant undershooting of the spatial targets (Experiment 3). Movement context in terms of response endpoint location or movement length did not have an apparent effect on directional errors. Performances in all experimental conditions were biased in the direction of the movement during learning. The context provided by movement direction did influence the encoding of kinesthetic spatial information.  相似文献

The aim of this study was to identify the anthropometric and physical prerequisites for high difficulty floor tumbling and vaulting. Twenty 8-14 year old female talent-selected gymnasts performed handstand push-offs, and single and multiple jumps on a portable Kistler force plate. The force curves were analysed using Kistler and Excel software to obtain peak displacement, peak take-off force, and power The gymnasts were also assessed for sprinting, with and without vaulting, and standing broad jump performances. Video footage from the vault take-off was analysed using Video Expert II software to obtain the horizontal and vertical take-off velocities. Each gymnast's best vault starting score, three best floor tumbling skills, and anthropometric characteristics were recorded. Statistical analysis included one-way analysis of variance (ANOVA) to examine the effect of age (8-10 years, 11-12 years, 13-14 years) on the performance measures and linear regression analysis with performance start score for vault or best floor tumbling score as the outcome variable. The best regression model for indicating vaulting talent had, as predictor variables, resultant velocity at take-off from the board, squat jump power, and average power during the last five jumps in the continuous bent-leg jump series. The best regression model for indicating floor tumbling ability had, as predictor variables, age, vault running velocity, and reduced ground contact time in a handstand push-off.  相似文献

Abstract

Individuals have to reweight the respective contribution of the different sources of sensorial information for regulating posture and balance, especially during fine task execution. Given the evidences indicating strategy during swing performance as associated with prioritization of task-relevant visuospatial information for skill execution, the aim of the present work is to assess differences in visual dependency (VD) and postural control in a population of expert (EXP) and non-expert (NEXP) golfers when compared with healthy subjects (HC) and to discover possible relationships between these outcomes and swing performance. Thus, 15 golfers (EXP?=?7; NEXP?=?8) and 32 matched HC underwent otoneurological testing including video Head Impulse Test, posturography and Rod and Disk Test (RDT). Golf players also underwent a swing session procedure, which performance was measured by means of the Flightscope X2 Doppler-radar launch monitor system. EXP subjects demonstrated significant (p?<?0.05) lower values in i) counter-clockwise (CCW) and clockwise (CW) dynamic conditions when compared with both NEXP and HC subjects RDT outcome measures and ii) surface and length posturography values as compared with HC subjects. When treating golf players outcomes as ‘a continuum’, CCW and CW scores were found to positively correlate with both lateral distance and horizontal launch angle and to negatively correlate with spin rpm. In conclusion, the present study suggests that the high-level of visual-independency demonstrated by EXP subjects may be functionally related in expert golfers to an effective motor strategy preferentially not referring to an inappropriate reliance on visual input.  相似文献

Abstract

Rock climbing is a popular adventure sport for which there is a growing body of scientific knowledge. There is, however, a lack of sport-specific assessment tools to monitor performance. The aim of this study was to examine the potential of the rock-over climbing test (ROCT) as a measure of climbing performance. The ROCT was conducted on a climbaflex board and involved the climber making a rock-over move for which the height gained from lower to upper handhold was measured. Results indicated there was a significant relationship between scaled (to the height of the climber) ROCT scores and climbing ability (r=0.67, P<0.0005). Regression modelling revealed that the ROCT explained 45% of the variance in scores between climbers. The ROCT differentiated between climber ability levels. Mean ROCT scores for novice, intermediate, advanced, and elite climbers were 59.5%, 71%, 82%, and 90% of participant height respectively. Results of analysis of variance revealed that these differences were significant (F 3,42=13.38, P<0.0005). Limits of agreement and intra-class correlation indicated that the ROCT is a reliable performance measure. Our findings suggest that the ROCT is a useful measure of climbing performance.  相似文献

Abstract

The purpose of this study was to determine: (a) if preperformance behaviors display a consistent rhythm across disparate activities; and (b) the relationship of periodicity for such preperformance routines to successful performance. Seven male volunteers were subjects for this study. Each subject had an established ritual for golf putt, basketball free throw, and tennis serve. Data were collected with a motion-analysis system and video camera while the subjects performed each activity. Dependent measures were types of preperformance behaviors, absolute timing of behaviors, relative timing of behaviors, differences in relative times across activities, and successful performance, and mechanical variables related to performance. Analysis of variance (Subject x Activity) indicated significant main effects and interactions for absolute and relative timing of behaviors. Significant correlations were determined to exist between relative time and success, and differences were found between relative times across activity and successful performance. It was concluded that rituals result from endogenous rhythms and that stable periodicity of behaviors across activities promotes successful performance.  相似文献
