The present study explored the effects of gender stereotype threat and conceptions of ability on motor learning and working memory in novice female learners. 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.
本研究探讨了性别刻板印象威胁和能力观念对女性初学者运动学习和工作记忆的影响。60名参与者(年龄21.92岁,年龄1.74岁)被随机分配到性别刻板印象威胁组和对照组(中性组;没有刻板印象威胁)。每一组依次被随机分成两个小组:先天能力组和后天技能组。分配给参与者的任务包括足球运球和n-back测试。在前测阶段,个体只进行一次运球试验,而在练习阶段,个体根据各自的测试条件进行了5次试验中的12次。在压力下保持和转移期间(两项测试练习后48小时),参与者进行了五组试验中的一组。参与者还在前测、后测和记忆保留阶段完成了n-back测试。在运动表现和学习两方面,性别刻板印象威胁和内在能力变量均对足球运球技术产生负向影响(p . 0.05)。讨论了这些变量如何影响或不影响运动学习以及工作记忆,以及如何将结果应用于运动领域。

This study aimed to develop and evaluate the acceptability and feasibility of a web-based platform for parents to support preschoolers’ development of physical literacy. Specifically, this intervention focused on children’s motor and social-emotional skill development. Twenty parents ( M age = 35.7, SD = 4.2) of preschool-aged children ( M age = 4.1, SD = 0.6) were assigned three intervention modules and completed weekly usage and feedback questionnaires (1 = strongly disagree , 5 = strongly agree ). Parents ( n = 15) also completed a follow-up interview. Parents indicated the modules were useable (4.5/5), useful (4.5/5), feasible (4.4/5), enjoyable (4.5/5), and acceptable (4.5/5). Five themes underlying parental engagement were generated: (a) activity organization and planning , (b) (de)motivators , (c) parent knowledge and skills , (d) experience with the platform , and (e) application to everyday routines . The online modules under investigation were deemed both acceptable and feasible by parents. However, factors such as time and knowledge may impact parental engagement at home. Future research is needed to better understand the antecedents to parent physical literacy support behaviors in the early years.
本研究旨在开发并评估家长支持学龄前儿童身体素养发展的网络平台的可接受性和可行性。具体来说,这种干预侧重于儿童运动和社交情感技能的发展。20名学龄前儿童家长(M年龄= 4.1,SD = 4.2)被分配3个干预模块,并完成每周使用情况和反馈问卷(1 =强烈不同意,5 =强烈同意)。15名家长也完成了随访。家长认为这些模块是可用的(4.5/5)、有用的(4.5/5)、可行的(4.4/5)、令人愉快的(4.5/5)和可接受的(4.5/5)。产生了五个潜在的家长参与主题:(a)活动组织和计划,(b)动机,(c)家长知识和技能,(d)使用平台的经验,以及(e)应用于日常生活。接受调查的在线模块被家长认为是可以接受和可行的。然而,时间和知识等因素可能会影响父母在家庭中的参与度。未来的研究需要更好地了解父母早期身体素养支持行为的前因。

This study was conducted to determine how total fundamental movement skill (FMS) score and, separately, locomotor skill (LMS), and object control skill scores in children 3–8 years old predicted their specific-intensity physical activity 3 years later. Overall, 441 Finnish children (51.7% female, baseline mean age of 5.6 years) participated in the study. 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.
本研究旨在确定3 - 8岁儿童的基本运动技能(FMS)总分、运动技能(LMS)和物体控制技能评分如何预测其3年后特定强度的身体活动。总共有441名芬兰儿童(51.7%为女性,基线平均年龄5.6岁)参与了这项研究。FMS、LMS和物体控制技能总分采用大肌肉运动发展测试(第三版)进行评估。参与不同强度的体力活动(轻度、中度、剧烈、中度至剧烈、轻度至剧烈和久坐行为)的时间是用加速度计测定的。考虑到潜在协变量和相互作用,在分析中使用了两水平回归模型。结果显示,FMS总分(β = 0.177 ~ 0.203, p = 0.001 ~ 0.003)和LMS总分(β = 0.140 ~ 0.164, p = 0.004 ~ 0.014)对中度、剧烈和中至剧烈运动有预测作用,但对物体控制技能得分无预测作用。此外,LMS评分与久坐行为呈负相关(β = - 0.116, p = 0.042)。总之,随着时间的推移,FMS分数越高,特别是LMS分数越高,似乎预示着人们会更多地参与中等到高强度的体育活动,而久坐的行为则越少。然而,体力活动的大部分差异仍然无法解释。

Rater training is necessary to accurately evaluate fundamental motor skills among children with developmental disabilities (DD). The purpose of this pilot study was to examine the impact of an online rater training program for novice raters on scoring accuracy of the run and two-hand strike skills on the Test of Gross Motor Development—Third Edition (TGMD-3) among children with DD. A training program was created consisting of two units/modules. The first module introduced the TGMD-3 and the second outlined behavior, movement characteristics, and correct scoring for the run and two-hand strike for children with DD. Forty-one novice raters completed three rounds of training and scoring. Data analysis compared the change of rating accuracy of novice raters on the run and two-hand strike skills of the TGMD-3 across three different occasions. There was a statistically significant positive impact on the scoring accuracy of novice raters for the run, two-hand strike skills, and the total skill score ( p < .001). The TGMD-3 online rater training program for novices in the present study could provide a model training program to improve the accuracy of scoring fundamental motor skills among children with DD.
为了准确评估发育障碍儿童的基本运动技能,有必要进行更严格的训练。本初步研究的目的是检验在线评分员培训项目对DD儿童大肌肉运动发展测试第三版(TGMD-3)中跑动和双手击球技能得分准确性的影响。该培训项目由两个单元/模块组成。第一个模块介绍了TGMD-3,第二个模块概述了DD儿童的行为、运动特征以及奔跑和双手击球的正确评分。41名新手评分员完成了三轮训练和评分。数据分析比较了三种不同情况下新手评分员在TGMD-3的跑动和双手击球技能上的评分准确率的变化。新手评价者在跑步、双手打击技能和总技能得分上的得分准确性有统计学上显著的正影响(p <措施)。本研究的TGMD-3在线新手评分员训练方案可为提高DD儿童基本运动技能评分的准确性提供一个模型训练方案。

Recent metascience suggests that motor behavior research may be underpowered, on average. 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.
最近的元科学表明,平均而言,运动行为研究可能缺乏动力。研究人员可以进行先验的功率分析,以确保充分的功率研究。然而,存在一些常见的缺陷,可能导致低估给定设计和效应大小所需的样本量。功率分析的关键评估需要成功的分析再现,这是有条件的报告足够的信息。在这里,我们试图重现2019年1月至2021年6月期间三份运动行为期刊上的文章(k = 84/635)中报告的所有功率分析。我们使用报告的信息再现了7%的分析,当我们假设缺失参数的合理值时,这一比例增加到43%。在报告了足够信息进行评估的研究中,63%的研究报告在功效分析中使用了与研究本身相同的统计检验,77%的研究报告使用了至少一个已确定的假设。总的来说,功率分析通常没有足够的信息来确保可重复性。大量的功率分析也受到常见缺陷的影响。通过越来越多地采用功率分析和确保可重复的报告实践,有大量的机会来解决动力不足的问题。

Purpose: To examine the factor structure and measurement invariance of the Körperkoordinations Test Für Kinder (KTK) and covariates of motor competence in a sample of Iranian children aged 5–14 years. Methods: Participants were children aged 5–14 years (N = 432, 61% boys). Age, sex, and body mass index were collected. Confirmatory factor analysis (CFA) was conducted to investigate the factorial structure of KTK and multigroup CFA carried out to test measurement invariance across sexes and age groups. In addition, we calculated a model with covariates to identify the association between KTK items with age, sex, and body mass index z score. 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. Finally, adequate fit indices were found for the multigroup CFA path model of KTK with the covariates sex, age, and body mass index z score. Conclusion: The KTK is a valid, reliable, and valuable instrument for assessing motor competence of Iranian children and adolescents.
目的:探讨伊朗5 ~ 14岁儿童运动能力Körperkoordinations KTK测试(KTK)及协变量的因素结构和测量不变性。方法:参与者为5-14岁的儿童(N = 432, 61%为男孩)。收集年龄、性别和体重指数。采用验证性因子分析(Confirmatory factor analysis, CFA)研究KTK的因子结构,采用多组验证性因子分析(multigroup CFA)检验不同性别和年龄组的测量不变性。此外,我们计算了一个带有协变量的模型,以确定KTK项目与年龄、性别和身体质量指数z分数之间的关联。结果:CFA支持单因素模型的结构效度,四个子测试对同一因素即运动能力具有适当的拟合指标。此外,根据嵌套模型间近似均方根误差和比较拟合指数的变化幅度,KTK测量在不同年龄组和性别之间的不变性假设成立。最后,以性别、年龄和体重指数z分为协变量,建立了KTK的多组CFA路径模型,找到了足够的拟合指标。结论:KTK是评估伊朗儿童和青少年运动能力的有效、可靠和有价值的工具。

In previous research, Canadian physiotherapists identified barriers to effective external focus promotion and recommended the delivery of a focus of attention workshop as a solution. Accordingly, the current research entailed the virtual delivery of such a workshop, consisting of asynchronous Website modules followed by a synchronous group session, to 15 Canadian physiotherapists working mainly with musculoskeletal rehabilitation clients. 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). Taken together, these results serve as a chain of evidence supporting the usefulness of the workshop in translating focus of attention findings into Canadian physiotherapy.
在之前的研究中,加拿大物理治疗师发现了有效的外部焦点促进障碍,并建议将注意力焦点研讨会作为解决方案。因此,目前的研究需要虚拟交付这样一个讲习班,包括异步网站模块,然后是同步小组会议,15名加拿大物理治疗师主要与肌肉骨骼康复客户一起工作。工作坊成果评估以社会认知理论和成人学习理论为指导,基于Kirkpatrick模型(kp1 -反应、kp2 -学习、kp3 -行为和kp4 -结果)的四个层次进行组织。具体来说,参与者在三个时间点收到问卷包的链接:研讨会前一周,研讨会后一周和研讨会后一周。结果显示,参与者(a)报告了高满意度、参与度和感知到的研讨会相关性(KP1);(b)从工作坊前到工作坊后,他们的知识、技能、态度和自我效能感均有显著改善(KP2);(c)自我报告在研讨会后一周内他们的外部焦点提升(修改KP3),以及由于这种外部焦点鼓励(修改KP4)而感知到的客户结果的改善。综上所述,这些结果作为一系列证据,支持研讨会在将关注焦点研究结果转化为加拿大物理治疗方面的有效性。

Effectiveness of motor interventions depends not only on learning content but also on the used teaching strategies. However, little is known regarding the application of teaching strategies in clinical practice. This study aimed to develop and assess psychometric properties of a new Dutch observational instrument to document teaching strategies: the Optimizing Performance through Intrinsic Motivation and Attention for Learning (OPTIMAL) Strategies Observational Tool (OSOT). Based on the OPTIMAL theory for motor learning from Wulf and Lewthwaite, the OSOT includes three variables: (a) expectancies, (b) autonomy, and (c) attention. The OSOT’s content was created by extracting relevant items from literature and existing instruments. To assess its psychometric properties, a convenience sample of 18 physiotherapy sessions for children with developmental coordination disorder was employed. Video recordings of these sessions were analyzed using Noldus The Observer XT. Relative duration (percentage of session time) was calculated for each item. Intraclass correlations were calculated to examine interrater and intrarater reliability. The design process resulted in 43 items in total. Interrater and intrarater intraclass correlations ranged from .48 to .99, with 81% (interrater), respectively, 95% (intrarater) of the items scoring above .75, indicating excellent agreement. The OSOT enables systematic and reliable observation of Optimizing Performance through Intrinsic Motivation and Attention for Learning teaching strategies used by therapists in Dutch clinical settings.
运动干预的有效性不仅取决于学习内容,还取决于所采用的教学策略。然而,对教学策略在临床实践中的应用了解甚少。本研究旨在开发和评估一种新的荷兰教学策略观察工具的心理测量特性:通过学习内在动机和注意力来优化表现(最佳)策略观察工具(OSOT)。基于Wulf和Lewthwaite的运动学习最优理论,OSOT包括三个变量:(a)期望,(b)自主性,(c)注意力。OSOT的内容是通过从文献和现有工具中提取相关项目而创建的。为了评估其心理测量特性,采用了18个发育协调障碍儿童物理治疗的方便样本。这些会议的视频记录使用Noldus The Observer XT进行分析。计算每个项目的相对持续时间(占会话时间的百分比)。计算组内相关性以检验组间和组内信度。设计过程总共产生了43个项目。评分者和内部人之间的相关系数范围为0.48 ~ 0.99,分别有81%(内部人)和95%(内部人)的评分高于0.75,表明一致性非常好。OSOT能够系统可靠地观察通过内在动机和注意力来优化荷兰临床治疗师使用的学习教学策略。

Does the Degree and/or Direction of Handedness in Children With Developmental Coordination Disorder Influence Motor and Cognitive Performance? A Pilot Study 发育性协调障碍儿童的利手程度和/或方向是否影响运动和认知表现?一项初步研究

Research has shown that nonright-handedness in children with developmental coordination disorder (DCD) is associated with poorer motor and cognitive performance. This study investigated the influence of degree and direction of handedness on performance using the Home Handedness Questionnaire, the Hit-the-Dot test, the Movement Assessment Battery for Children, and the digital Trail-Making Test. Eighteen children with DCD and 21 typically developing children aged 8–12 years participated in this study. The distribution of degree and direction of handedness in the group of DCD children were not different from that found in the typically developing group. In the Hit-the-Dot test, typically developing children significantly performed better than children with DCD, no matter which hand was dominant or to which degree. A significant inconsistent-handed advantage in the subdomain balance was found for children with DCD. Inconsistent handedness also seems to be an advantage for children with DCD on the digital Trail-Making Test performance. The relationship between the subcategories of the Movement Assessment Battery for Children and the digital Trail-Making Test part B is stronger for consistent than for inconsistent handedness. Our findings suggest that children with DCD and inconsistent handedness might benefit from greater crosstalk across hemispheres. In addition, these predispositions can be reinforced or discouraged throughout development and via occupational therapy.
研究表明,患有发育性协调障碍(DCD)的儿童的非右手性与较差的运动和认知表现有关。本研究采用“惯用手问卷”、“打点测验”、“儿童运动评估测验”和“数字轨迹测验”,考察了惯用手程度和惯用手方向对成绩的影响。18名DCD儿童和21名8-12岁的正常发育儿童参加了本研究。DCD组儿童的手性程度和方向分布与正常发育组无明显差异。在Hit-the-Dot测试中,正常发育儿童的表现明显优于DCD儿童,无论哪只手占主导地位或在多大程度上占主导地位。在DCD患儿的子域平衡中发现了显著的不一致手优势。不一致的手性似乎也是DCD儿童在数字轨迹测试中的一个优势。儿童运动评估组与数字轨迹测试B部分的子类别之间的关系在一致性方面比不一致性方面更强。我们的研究结果表明,患有双性手性障碍和不一致手性的儿童可能会从两脑半球之间更大的相互作用中受益。此外,这些倾向可以在整个发展过程中通过职业治疗得到加强或抑制。

This study aimed to investigate the effect of part and whole practice on learning basketball lay-up shot skill in young and adolescent male students. Participants were randomly divided into four groups of part and whole practice, namely, part practice-young, whole practice-young, part practice-adolescent, and whole practice-adolescent. After a pretest in basketball lay-up shot test, the training protocol was held for 5 weeks (three sessions per week). After the last training session, the posttest was taken, and 1 week after the posttest, a retention test was performed. The results in the acquisition stage showed a significant difference between the four groups (p = .03). The post hoc test results showed that there was no significant difference between the part and whole practice groups. Also, in the retention phase, there was no significant difference between the groups. However, the part practice-young group performed better than the whole practice-young group, while the whole practice-adolescent group performed better than the part practice-adolescent. According to the research findings, it can be concluded that age is probably not an effective factor in the effectiveness of part and whole practice in learning basketball lay-up shot. However, more research with more practice trials is needed in this regard.
摘要本研究旨在探讨局部训练与整体训练对青少年男学生篮球上篮技巧学习的影响。参与者被随机分为部分和整体实践四组,即部分实践-青少年、整体实践-青少年、部分实践-青少年和整体实践-青少年。在篮球上篮测试前测后,进行为期5周(每周3次)的训练方案。最后一次训练结束后进行后测,后测1周后进行记忆力测试。四组在习得阶段的结果有显著性差异(p = .03)。事后检验结果显示,部分练习组与整体练习组之间无显著差异。此外,在保留期,各组之间没有显著差异。然而,部分实践-青少年组表现优于整个实践-青少年组,而整个实践-青少年组表现优于部分实践-青少年组。根据研究结果,可以得出结论,年龄可能不是影响篮球上篮部分练习和整体练习效果的有效因素。然而,在这方面需要更多的研究和更多的实践试验。
