Participants were 3- to 5-year-old children (N = 316; 49.6% female) who participated in the 2012 National Youth Fitness Survey. GMS was assessed using the gross motor quotient calculated from the Test for Gross Motor Development—Second Edition. PA was assessed using wrist-worn ActiGraph GT3X accelerometers with raw triaxial acceleration data summarized using monitor-independent movement summary units (MIMS). Analyzed metrics included average MIMS per day and peak 30-min MIMS. HRF assessment consisted of a plank score and a sum of skinfold assessment. Weighted hierarchical regressions tested the associations between PA, HRF, and GMS variables with a secondary weighted mediation analysis that examined whether HRF mediated the association between PA and GMS. Peak 30-min MIMS significantly correlated with GMS (b = 0.17, p = .005). Plank scores had the strongest correlation with GMS (b = 0.23, p = .004), and weighted mediation analyses revealed that plank scores partially mediated the association between peak 30-min MIMS and GMS (indirect effect = 0.03, p = .01, 23.1% mediation). Peak 30-min MIMS significantly associated with GMS in preschool children, an association partially mediated by core muscular endurance.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"13 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83588345","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 used functional near-infrared spectroscopy to compare prefrontal cortex (PFC) activity in TD and pDCD during the completion of manual (three-dimensional [3D]) and computerized versions (two-dimensional) of the Tower of Hanoi (ToH) puzzle. Method: A total of 12 children (TD and pDCD; one female/11 male, , SD ± 1.52 years) performed the two-dimensional and 3D conditions of the ToH disk tasks, with equivalent executive function but different motor requirements, with functional near-infrared spectroscopy to compare PFC activity. Results: Interestingly, brain oxygenation levels were more apparent in the 3D versus two-dimensional ToH. In the 3D, there were large differences between pairs of discordant sibling sets and this was located to the right medial PFC, with pDCD exhibiting less activation in this region. Conclusion: While only exploratory, we have identified potential differences in the right medial PFC region, which differs within sibling sets with different pDCD status. These results concur with previous studies and are an area that needs to be explored further with a larger cohort of TD and pDCD.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"25 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84481699","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}

Seventeen boys (age, 10.1 ± 1.6 years; height, 1.45 ± 0.11 m; mass, 26.7 ± 7.83 kg) undertook isokinetic strength assessments of concentric and eccentric trunk flexors/extensors at 60°/s, and anterior/medial hop tasks. Hierarchical multiple regressions determined whether concentric and eccentric trunk flexor/extensor peak torques predict TTS using a composite score (CompX CompY CompZ) and CoPX and CoPY. Concentric trunk flexors were the strongest predictor for TTS CompXY, with concentric flexion and eccentric extension predicting TTS CompY. All muscle actions were also strong predictors for CoPY during hop tasks. These findings have implications for the assessment of trunk musculature strength and measures of postural control within a young healthy population. The development of trunk musculature strength may aid improvements in dynamic balance tasks in children, with implications for fall and injury risk. To improve trunk musculature strength and the potential to maintain postural control, a combination of concentric and eccentric exercises with other training modalities appears relevant due to the increased relevance to the demands of balance maintenance.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"48 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84147873","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}

Sixty participants (Mage = 21.92 years, SDage = 1.74) were randomly assigned into a gender stereotype threat and a control group (neutral; without stereotype threat). Each group was, in turn, randomly divided into two subgroups: inherent ability and acquired skill. The tasks assigned to the participants included soccer dribbling and the n-back test. In the pretest, the individuals only performed one dribbling trial, whereas in the practice phase, the individuals performed 12 blocks of five trials based on their respective test conditions. During retention and transfer under pressure (48 hr after practice for both tests), the participants carried out one block of five trials. The participants also completed the n-back test in the pretest, posttest, and retention phases. In both motor performance and learning, the findings suggested that both gender stereotype threat and inherent ability variables can negatively influence the soccer dribbling skill (p < .05). However, regarding working memory, the results could not show any significant difference between the groups (p > .05). How these variables affect or do not affect motor learning as well as working memory and how the results are applied in the motor domain are discussed.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"85 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89437936","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}

Total FMS, LMS, and object control skill scores were assessed using the Test of Gross Motor Development, third edition. The time spent engaged in physical activity of different intensities (light, moderate, vigorous, moderate-to-vigorous, light-to-vigorous, and sedentary behavior) was determined using accelerometers. A two-level regression model was used in the analysis, considering potential covariates and interactions. The results showed that moderate physical activity, vigorous physical activity, and moderate-to-vigorous physical activity were predicted by the total FMS score (β = 0.177 to 0.203, p = .001–.003) and the LMS score (β = 0.140 to 0.164, p = .004–.014), but not the object control skill score. Moreover, the LMS score inversely predicted sedentary behavior (β = −0.116, p = .042). In conclusion, higher FMS and, specifically, LMS scores seem to predict more engagement in moderate-to-vigorous physical activity and less sedentary behavior over time. However, most of the variance in physical activity remains unexplained.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135801404","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}

Researchers can perform a priori power analyses to ensure adequately powered studies. However, there are common pitfalls that can result in underestimating the required sample size for a given design and effect size of interest. Critical evaluation of power analyses requires successful analysis reproduction, which is conditional on the reporting of sufficient information. Here, we attempted to reproduce every power analysis reported in articles (k = 84/635) in three motor behavior journals between January 2019 and June 2021. We reproduced 7% of analyses using the reported information, which increased to 43% when we assumed plausible values for missing parameters. Among studies that reported sufficient information to evaluate, 63% reported using the same statistical test in the power analysis as in the study itself, and in 77%, the test addressed at least one of the identified hypotheses. Overall, power analyses were not commonly reported with sufficient information to ensure reproducibility. A nontrivial number of power analyses were also affected by common pitfalls. There is substantial opportunity to address the issue of underpowered research in motor behavior by increasing adoption of power analyses and ensuring reproducible reporting practices.","PeriodicalId":37368,"journal":{"name":"Journal of Motor Learning and Development","volume":"2 1","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89876731","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}

Results: CFA supported the construct validity of a one-factor model with an appropriate fit indices that the four subtests loaded on the same factor namely motor competence. Furthermore, according to the magnitude of changes in root mean square error of approximation and comparative fit index between nested models, the assumption of KTK measurement invariance across age-groups and sex were valid.

Assessment of the workshop outcomes was guided by constructs of social cognitive and adult learning theory, and organized based on the four levels of the Kirkpatrick model (KP1-Reaction, KP2-Learning, KP3-Behavior, and KP4-Results). Specifically, participants received links to questionnaire packages at three time points: 1-week preworkshop, immediately postworkshop, and 1-week postworkshop. Results showed that participants (a) reported high satisfaction, engagement, and perceived relevance of the workshop (KP1); (b) experienced significant improvements to their knowledge, skills, attitudes, and self-efficacy from pre- to immediately postworkshop (KP2); and (c) self-reported increases to their external focus promotion in the week following the workshop (modified KP3), and perceived improvements to their clients’ outcomes as a result of this external focus encouragement (modified KP4).
