Method: The authors adopted the reverse translation procedures to obtain the PSPPS-BR’s Brazilian-Portuguese version. Three motor behavior experts assessed the scale items’ clarity and pertinence. Ten professionals participated in the face validity study. Children (N = 300; 150 girls and 150 boys; 8–10 years old; Mage = 9.0, SD = 0.81) were randomly selected from six schools in Brazil and assessed using the PSPPS-BR, the Pictorial Scale of Perceived Movement Skill Competence, and the Self-Perception Profile for Children. The children (N = 100) were reassessed for test–retest reliability. Results: High clarity and pertinence agreement among experts (content validity coefficient from 98.4% to 100%; Gwet’s agreement coefficient from .85 to 1.00, p < .001) and among professionals (content validity coefficient clarity: 83–100%, relevance: 90–100%) were obtained. The confirmatory factorial analysis showed adequate model fits (root mean square error of approximation = .067; comparative fit index = .968; Tukey–Lewis index = .949). Polychoric correlations showed an adequate internal consistency for total scale (α = .78) and items (alpha from .73 to .78). The intraclass coefficient correlation shown strong test–retest reliability (intraclass correlation coefficient > .95). Conclusion: The PSPPS-BR showed adequate validity and reliability for Brazilian children.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"8 1","pages":"1-20"},"PeriodicalIF":1.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89419108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were randomly assigned to one of the four groups: enhanced expectancies and autonomy support (EE/AS), enhanced expectancies (EE), autonomy support (AS), or control (CON) groups. Participants learning the skill were or were not provided enhanced expectation instructions by making the task success easier and provided an opportunity to choose one of the three colored balls during their practice. Two days later, they performed retention and transfer tests. Results indicated that the EE/AS group had the highest scores, with main effects of autonomy support being significant and enhanced expectancies being marginally significant for the retention test and significant for the transfer test. The EE/AS group had the highest self-efficacy and perceived choice scores.

Methods: A convenience sample of (N = 496; Mage = 7.23 ± 2.03 years; 53.8% female) typically developed children participated in this study. Three alternative measurement models were tested: (a) a unidimensional model, (b) a correlated two-factor model, and (c) a bifactor model. Results: The totality of results, including item loadings, goodness-of-fit indexes, and reliability estimates, all supported the bifactor model and strong evidence of a general factor, namely gross motor competence. Additionally, the reliability of subscale scores was poor, and it is thus contended that scoring, reporting, and interpreting of the subscales scores are probably not justifiable. Conclusions: This study shows the advantages of using bifactor approach to examine the TGMD-3 factor structure and suggests that the two traditionally hypothesized factors are better understood as “grouping” factors rather than as representative of latent constructs. In addition, our findings demonstrate that the bifactor model appears invariant for sex.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"13 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82166782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysis and synthesis of the experimental findings leads to the proposition that proximal–distal is one of several within-limb patterns of coordination, including: the reverse distal–proximal sequence, simultaneous activation of segments, and other sequence variations of this. The probability of particular patterns occurring is induced by task constraints and skill level of the individual, together with their evolving biomechanical consequences, including: open/closed chain, absorption/propulsion of force, magnitude of momentum, and accuracy/timing. We develop the theoretical perspective that classes of task constraints induce particular types of neuromechanical organization to within-arm or within-leg segment coordination. In this task constraint framework, proximal–distal within-limb organization is a particular rather than a general case for within-limb coordination. The limitations of anatomically-based accounts of directional change for within-limb organization are discussed with reference to a general functional degrees of freedom task constraint framework for movement coordination and control.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"68 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83527276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that 60% of participants followed an S-shaped performance curve with the inflection date on the 11th day, followed by a decelerated (20%), accelerated (14%), and linear curve (6%). As expected, except on Day 1, male participants performed at least 33% better than female participants on each practice day. Also as expected, learning performance was found to depend on the type of performance curve with the best learning performance exhibited by the linear group. The results further revealed that pooling all participants’ performance together without considering the percentage of each underlying type of performance curve would lead to biased, nonrepresentative results. Given the variety of the observed performance curves and the dominance of the S-shaped performance curve among them, coaches should continuously monitor the shape of an individual’s performance curve.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"73 1","pages":"1-17"},"PeriodicalIF":1.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86248996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eighteen participants (age: 20.20 ± 2.90 years, nine women) were divided into two intervention groups: a pulling group taught to engage the nonthrowing arm through a pull toward the body and a nonpulling group taught the overhand throw using a component-based physical education curriculum. Each participant completed 12 total throws, six for each side (dominant and nondominant arm). Ball speed and kinematic data were collected using an eight-camera motion analysis system and were assessed using a pre–post study design. The two groups showed significant improvements pre–post when throwing with both the dominant and nondominant arms.

The Delphi method was used to select the dimensions of MC. Confirmatory factor analysis was used to assess whether the dimensions loaded onto the same construct (i.e., MC). Face and content validity identified three dimensions of MC: fundamental motor skills, gross motor coordination, and motor abilities. Confirmatory factor analysis indicated an adequate fit for the final MC model with three dimensions. In this model, fundamental motor skills, gross motor coordination, and motor abilities loaded on the MC construct. The data reported present a revised definition of holistic MC, which comprises the level of motor abilities (physical proficiency and perceptual motor abilities) as well as gross motor coordination and fundamental motor skills proficiency, which underlie the performance of a wide range of tasks, including fine and gross motor activities in daily life.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"13 1","pages":"1-25"},"PeriodicalIF":1.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90662544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes a new assessment protocol for aquatic motor competence and sets out to examine the validity of the Aquatic Movement Protocol (AMP) in children between 7 and 9 years of age. Testing of Gross Motor Development—second edition was implemented to assess general motor competence, including a composite of 10-m running sprint time and standing long jump distance. Aquatic motor competence was assessed by the AMP. Univariate analyses of covariance were used to examine whether assessment of general motor competence differed as opposed to aquatic motor competence. Process and product measures of dryland motor competence were analyzed using male and female subjects measuring three aquatic motor competences (low, medium, and high). Cronbach’s alpha and exploratory factor analyses were implemented to show both construct and concurrent validity of the AMP. Children classified as high for aquatic motor competence had significantly higher general motor competence (p = .001). Those who achieved a higher composite score for faster sprint speeds and longer jump distances had significantly higher aquatic motor competence (p = .001). Cronbach’s alpha of .908, showed internal consistency of the AMP. Results extracted one factor from analysis with an eigenvalue = 6.2; %variance = 62.1, with loadings higher than 0.5. This data suggests that the items on the AMP measure a single construct that we would call “Aquatic Motor Competence.” This study demonstrates that the AMP is a valid measure of aquatic motor competence in primary aged children.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"48 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89972698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
