PURPOSETo determine the effects of a 10-month secular (SEC) versus faith-integrated (FI) community-based physical activity (PA) intervention on cardiometabolic risk factors in low active, African-American women.METHODSParticipants (age: 55.4±11.6 years; body mass index (BMI): 36.0±7.9 kg/m2; average baseline steps/day: 3,807±1,250) from a larger study (n=418) participated in a sub-study to measure cardiometabolic disease indicators (primary outcomes) and PA (secondary outcomes) pre- and post-intervention (SEC: n=42; FI: n=43). Height, weight, waist and hip circumferences, resting blood pressure, hemoglobin A1c, average steps/day, sedentary behavior, light-intensity physical activity (LPA), and moderate-to-vigorous-intensity physical activity (MVPA) were acquired at baseline and 10 months. Multivariate generalized linear mixed models that included churches as a random effect were used to compare mean changes in outcomes at 10 months between the two study groups (α=0.05).RESULTSThe FI group showed significant time effects for weight (93.4±2.4 to 92.2±2.3 kg), BMI (35.7±1.0 to 35.3±1.0 kg/m2), and waist circumference (106.9±2.2 to 103.8±2.5 cm), while the SEC group had a significant time effect for hip circumference (121.6±1.9 to 119.9±1.7 cm). There were no time effects in either group for blood pressure, hemoglobin A1c, steps/day, sedentary time, or MVPA. FI significantly decreased LPA in both 1-minute activity bouts (641±13 to 588±16 minutes/day) and 10-minute bouts (536±11 to 479±15 minutes/day). There were no significant differences between SEC and FI for any variable.CONCLUSIONSThe improvements in body weight, BMI, and waist circumference shown after the FI intervention could have long-term implications on cardiometabolic health, particularly if exercise is continued. Further research is needed to examine the effects of culturally-relevant interventions on chronic disease indicators in African-American women, particularly those established as high risk for cardiometabolic disease.
目的确定10个月的长期(SEC)与信仰综合(FI)社区体育活动(PA)干预对低活动性非裔美国妇女心脏代谢风险因素的影响。方法受试者(年龄:55.4±11.6岁;体重指数:36.0±7.9 kg/m2;平均基线步数/天:3807±1250)参与了一项亚研究,以测量干预前后的心脏代谢疾病指标(主要结果)和PA(次要结果)(SEC:n=42;FI:n=43)。在基线和10个月时测量身高、体重、腰围和臀围、静息血压、血红蛋白A1c、平均步数/天、久坐行为、轻强度体力活动(LPA)和中等强度至剧烈强度体力活动。使用包括教堂作为随机效应的多变量广义线性混合模型来比较两个研究组在10个月时的平均结果变化(α=0.05)。结果FI组在体重(93.4±2.4至92.2±2.3 kg)、BMI(35.7±1.0至35.3±1.0 kg/m2)和腰围(106.9±2.2至103.8±2.5 cm)方面表现出显著的时间效应,而SEC组对臀围有显著的时间效应(121.6±1.9至119.9±1.7cm)。两组的血压、血红蛋白A1c、步数/天、久坐时间或MVPA均无时间效应。FI在1分钟的活动周期(641±13至588±16分钟/天)和10分钟的活动期(536±11至479±15分钟/日)中均显著降低LPA。SEC和FI在任何变量上都没有显著差异。结论FI干预后体重、BMI和腰围的改善可能对心脏代谢健康产生长期影响,特别是如果继续运动。需要进一步研究文化相关干预措施对非裔美国妇女慢性病指标的影响,特别是那些被确定为心脏代谢疾病高风险的妇女。

The increasing prevalence of noncommunicable diseases and multimorbidity negatively affects an individual’s quality of life and health trajectory; this trend and resultant personal and clinical outcomes are of significant concern. Healthy living (HL) behaviors (physical activity, dietary modification, smoking cessation, and medication compliance) are known to provide substantial health benefits that slow the progression or in some cases reverse the deleterious effects associated with inactivity and consumption of a diet high in sodium, fat content, added sugars, and energy-dense foods. However, it is becoming increasingly clear that a one-size-fits-all approach to HL interventions in populations at risk for or diagnosed with noncommunicable diseases is inadequate to promote optimization of health outcomes. Practitioners implementing HL interventions, such as clinical exercise physiologists (CEP), must instead understand the complexity or multimorbidity phenotypes and be able to effectively tailor programs for each condition. Although CEP may receive master’s level training in this area, the rise in patients with complex multimorbidity warrants consideration of elevating the professional expectations to better prepare CEP in training to deliver highly effective primary and secondary prevention HL interventions. Many licensed allied health professions (i.e., physical therapy, pharmacy, occupational therapy, nursing, nutrition, etc.) have recognized the call to move toward professional doctoral degree programs to better prepare practitioners within their field. This article proposes a professional doctorate degree program aimed at enhancing the training of CEP to become highly effective practitioners.
非传染性疾病和多病的日益流行对个人的生活质量和健康轨迹产生负面影响;这种趋势和由此产生的个人和临床结果值得关注。健康生活(HL)行为(体育活动、饮食调整、戒烟和药物依从性)提供了实质性的健康益处,可以减缓进展,或在某些情况下逆转与不活动和高钠、高脂肪、添加糖和高能量食物的饮食相关的有害影响。然而,越来越清楚的是,对有非传染性疾病风险或被诊断为非传染性疾病的人群采取一刀切的HL干预措施,不足以促进健康结果的优化。实施HL干预的从业者,如临床运动生理学家(CEP),必须了解复杂性或多发病表型,并能够有效地为每种情况量身定制方案。尽管CEP可能在该领域接受硕士水平的培训,但复杂多病患者的增加需要考虑提高专业期望,以更好地为CEP培训做好准备,提供高效的一级和二级预防HL干预措施。许多有执照的联合健康专业(即,物理治疗,药学,职业治疗,护理,营养等)已经认识到转向专业博士学位课程的呼吁,以更好地为他们领域的从业者做好准备。本文提出了一个专业的博士学位课程,旨在加强CEP的培训,使其成为高效的实践者。

With the complex role of the thyroid in metabolism and conflicting evidence of weight gain or loss as a result of prescription thyroid hormone replacement (THR), it is important to understand how THR affects weight loss beyond the standard measures of body weight % and body mass index (BMI). We examined differences in body composition improvement in individuals taking and not taking THR over 60 d of an intensive weight loss program. The 20Lighter Program (T20LP), a doctor-supervised weight loss and metabolic health program, included 6 wk of patent-pending very low calorie meal plans and a 3-wk customized transition back to a normal dietary intake. Of 2200 participants completing T20LP by December 31, 2017, ~10% reported taking prescription THR. From initial baseline to 60 d, T20LP participants from both groups showed statistically significant and clinically meaningful reductions in body weight, BMI, % body fat, visceral fat, metabolic age, and increases in % body water. To our knowledge, our study is the first large-scale analysis comparing weight loss outcomes in participants who take THR and participants who do not. Our data show both groups do equally well with respect to % body weight lost, BMI reduction, body fat and visceral fat reduction, and improvement in tissue hydration, and we found no disadvantage in any physiologic or metabolic outcome in weight loss participants on THR. Weight loss participants requiring prescription THR are capable of achieving body composition and metabolic improvements on par with those who do not require prescription THR.
由于甲状腺在代谢中的复杂作用以及处方甲状腺激素替代(THR)导致体重增加或减少的相互矛盾的证据,了解THR如何影响体重减轻是很重要的,超出了体重百分比和体重指数(BMI)的标准测量。我们研究了在60天的强化减肥计划中,服用和不服用THR的个体在身体成分改善方面的差异。20Lighter Program (T20LP)是一项由医生监督的减肥和代谢健康计划,包括6周正在申请专利的极低卡路里饮食计划和3周的定制过渡到正常饮食摄入量。在截至2017年12月31日完成T20LP的2200名参与者中,约10%的人报告服用处方THR。从初始基线到60 d,两组T20LP参与者的体重、BMI、体脂百分比、内脏脂肪、代谢年龄和体水百分比均有统计学意义和临床意义的降低。据我们所知,我们的研究是第一个比较服用THR和不服用THR的参与者减肥结果的大规模分析。我们的数据显示,两组在体重减轻%、BMI降低、体脂和内脏脂肪减少以及组织水化改善方面都做得很好,而且我们发现,服用THR的减肥参与者在任何生理或代谢结果上都没有不利之处。需要处方THR的减肥参与者能够达到与不需要处方THR的人相同的身体成分和代谢改善。

Schools are valuable locations to promote physical activity becausemost children are in school for large portions of the day and year. However, the main objective of most schools is to teach academic skills. For school personnel to implement classroom-based physical activity programs, they need to be convinced that these programs will help the students learn better. Teachers understand and value the concept of on-task behavior or paying attention. Without attentional focus, students do not learn. Thus, if research demonstrates that participation in classroombased physical activity programs enhances on-task behavior, teachersmay bemore likely to implement these programs. Although on-task behavior in the authentic classroom setting is difficult to measure, the accumulated evidence about the effect of classroom-based physical activity on on-task behavior is convincing. This article presents an overview of measurement issues associated with directly observed on-task behavior in schools and a summary of the key studies that have made a substantial contribution to the literature in this field. Various research designs and statistical comparisons have been used to examine these relationships. Several research studies have included examination of the effect of physical activity on on-task behavior within subgroups of students (e.g., level of attention, sex, fitness, race/ethnicity, and socioeconomic status). In summary, research demonstrates that classroom-based physical activity enhances on-task behavior compared with traditional sedentary learning environments, and this benefit appears to hold for all subgroups of students that have been examined. Specific suggestions to enhance the implementation of classroom-based physical activity and to further develop the research base are provided. INTRODUCTION Health benefits of physical activity are widely known (1,2); however, less is known about the additional benefits or potential limitations of physical activity when it is incorporated into the classroom. Research on the effectiveness of classroombased physical activity began to be published around the mid-2000s. Integrating physical activity into the classroom can help youth meet the U.S. Physical Activity Guidelines (3). Part of the Physical Activity Guidelines recommends that youth School of Exercise and Nutritional Sciences, San Diego State University,
学校是促进体育活动的宝贵场所,因为大多数孩子一年中大部分时间都在学校。然而,大多数学校的主要目标是教授学术技能。对于学校工作人员来说,实施基于课堂的体育活动计划,他们需要相信这些计划将帮助学生更好地学习。教师理解并重视任务行为或注意力的概念。没有注意力的集中,学生就不会学习。因此,如果研究表明,参与基于课堂的体育活动计划可以增强任务行为,那么教师可能更有可能实施这些计划。尽管在真实的课堂环境中进行任务行为很难衡量,但关于课堂体育活动对任务行为影响的累积证据是令人信服的。本文概述了与学校中直接观察到的任务行为相关的测量问题,并总结了对该领域文献做出重大贡献的关键研究。已经使用了各种研究设计和统计比较来检验这些关系。几项研究包括检查体育活动对学生亚组任务行为的影响(例如,注意力水平、性别、体质、种族/民族和社会经济地位)。总之,研究表明,与传统的久坐学习环境相比,基于课堂的体育活动可以增强任务行为,这一益处似乎适用于所有接受过检查的学生亚组。提出了加强课堂体育活动实施和进一步发展研究基地的具体建议。引言体育活动对健康的益处是众所周知的(1,2);然而,当体育活动被纳入课堂时,人们对其额外的好处或潜在的局限性知之甚少。关于课堂体育活动有效性的研究于2000年代中期开始发表。将体育活动融入课堂可以帮助青少年达到美国体育活动指南(3)。《体育活动指南》的一部分建议圣地亚哥州立大学青少年运动与营养科学学院,

The rise in childhood obesity coincides with children spending more of their formative years in child care or school environments, settings found to be strong predictors of children’s physical activity. Although most efforts focus on the social environment of the school, studies show there is potential to develop better evidence-based design guidelines for interventions in the physical environment that can afford more physical activity and support or complement other initiatives. In the context of the school, multiple studies long established that physical activity is correlated with time spent outside, but more recent studies found that the intentional design of outdoor spaces to have certain characteristics results in more participation of different groups and higher physical activity generally. However, there are many documented physical and social barriers to going outside, some of which could potentially be overcome through better design of the relationship between inside and outside, but there has been far less research into how the physical environment of the school building enables or hinders going outside in the first place. This article reviews and summarizes important findings in the literature that provide evidence of the effects that the physical environment of the school has on children’s health and resilience generally, andon their physical activitymore specifically; presents field observations from research on the design of schools in Finland—one of the best school systems in the world in one of themost challenging climateswith a strong tradition of outdoor learning and frequent time outside; and identifies gaps in knowledge and future directions for transdisciplinary research specifically focused on the design of active schools. INTRODUCTION: PHYSICAL ENVIRONMENT AND HEALTH Understanding the effects of the physical environment on children’s health is important to make better policy, guidelines for design, and decisions on capital investments. This is critical because medical researchers have found that children’s less mature systems are more susceptible to environmental hazards and that they have manymore years of life to develop problems (1). In turn, the opportunity for early life interventions can potentially influence healthy habits and behaviors that can positively shape their adult lives.

尽管针对学校的具体情况研究开始指导政策和项目干预,但有机会发展跨学科研究,也可以指导更好的循证设计、法规和在物理环境中的投资,从而支持其他努力的成功,以确保更好的结果。ACSM155翻译期刊禁止转载这篇文章。本文总结了文献中最重要的发现,这些发现提供了证据,证明学校的物理环境对儿童的健康和恢复力有影响,更具体地说,对他们的体育活动有影响;介绍了芬兰学校设计研究的实地观察结果。芬兰是世界上最好的学校系统之一,气候最具挑战性,有着强烈的户外学习传统和经常外出的时间;并确定了知识方面的潜在差距和未来的研究方向,特别关注活跃学校的物理环境设计,这可以支持儿童的体育活动、社会能力和更好的学习。所有年龄组的物理环境和体育活动研究现状城市化、人口增长、数字技术、食品系统、污染、气候变化以及其他改变自然和建筑环境的因素——这些因素可能阻碍或支持包括体育活动在内的健康习惯和结果——是研究人员越来越感兴趣的领域,政策制定者和设计师,感谢近几十年来的几项重要研究,本文对这些研究进行了回顾,并将在本节和下一节中提及。对文献的广泛回顾表明,这些研究通常采取两种形式:(A)相关性的确定,研究人员对社会或物理环境的属性进行观察,并测量健康结果,以确定是否存在强相关性,以及(b)在被怀疑存在某种缺陷或障碍的环境中设计干预措施,并测量这些干预措施对特定健康结果或行为的影响。在这两种类型的研究中,能够对物理环境进行有效的观察和准确的测量以及创造性的干预是很重要的。然而,研究团队通常不包括物理空间设计专业知识。最近的一项研究明确提到,建筑连贯性是身体活动的潜在重要因素,但无可否认,由于研究人员缺乏设计方面的专业知识,不得不对这一特征进行探索(8)。更好的研究可能更全面,并得到空间环境设计专业知识的更好支持,再加上设计有效和适当方法来衡量效果和结果的研究经验。研究身体环境和身体活动的相关性及其相关的健康结果,涵盖了广泛的年龄和身体环境特征。例如,衣服是我们身体最接近的物理环境组成部分,它的历史变化被假设减少了我们的能量支出(照顾它们),提高了我们抵御各种环境的能力(使锻炼更舒适)(9)。建筑物作为我们提供住所的衣服的延伸,是人们一生中大部分时间免受天气影响的地方。对空间内部配置的关注,特别是人们从一个地方移动到另一个地方的建筑流通系统,理论上会影响人们的体育活动欲望和动机。例如,楼梯等建筑元素通常很难找到或没有吸引力,可以设计成鼓励人们选择楼梯而不是电梯,从简单的标识策略到使其更开放、更方便、更具吸引力的改进措施(10)。办公环境的设计,特别是自然光的量,156第4卷•第17号•2019年9月1日版权所有©2019美国运动医学院显示,与人造光相比,睡眠和活力表现出更多的体力活动趋势,尽管尚不清楚这是原因还是影响(11)。城市环境的设计也影响健康,尤其是体育活动。无论是改善的可达性(8)、进入建筑和公园设施的便利性(12,13)、它们的物理位置以及一年中的时间(14),这些因素似乎都会影响一个人是否更有可能进行体育活动。

However, there are many documented physical and social barriers to going outside, some of which could potentially be overcome through better design of the relationship between inside and outside, but there has been far less research into how the physical environment of the school building enables or hinders going outside in the first place. This article reviews and summarizes important findings in the literature that provide evidence of the effects that the physical environment of the school has on children’s health and resilience generally, andon their physical activitymore specifically; presents field observations from research on the design of schools in Finland—one of the best school systems in the world in one of themost challenging climateswith a strong tradition of outdoor learning and frequent time outside; and identifies gaps in knowledge and future directions for transdisciplinary research specifically focused on the design of active schools. INTRODUCTION: PHYSICAL ENVIRONMENT AND HEALTH Understanding the effects of the physical environment on children’s health is important to make better policy, guidelines for design, and decisions on capital investments. This is critical because medical researchers have found that children’s less mature systems are more susceptible to environmental hazards and that they have manymore years of life to develop problems (1). In turn, the opportunity for early life interventions can potentially influence healthy habits and behaviors that can positively shape their adult lives.

Texas I-CAN! has focused on the development of interventions to provide physically active learning (PAL) to regular education, elementary classroom. This paper provides an overview of our approach and the iterations through which we have progressed the intervention. We adopt a framework that considers PAL along continuums of relatedness to and integration with the academic goals of the lessons. This provides a lens through which to view our iterations of I-CAN!, as we sought a version of PAL that is both acceptable to teachers and effective for physical activity and academic outcomes. As such, this provides an overview of the choices that must be made to translate theory to practice.

The prevalence of physical inactivity in children has become a global pandemic and has consequences for physical, as well as cognitive and brain, health. Single bouts of physical activity (PA), however, have shown a transient, positive effect on cognitive performance in preadolescent children. Acute bouts of moderate to vigorous PA have demonstrated benefits for cognition, including attention and executive function. These acute effects of PA on cognitive performance can be seen both immediately after and following a delay from the cessation of PA. Further, event-related potentials have been used to delineate real-time neural responses to behavioral tasks after PA interventions. A short bout of moderate-intensity aerobic PA serves to increase the allocation of attentional resources and improved cognitive processing and stimulus classification speed. As such, there are implications for evaluating the effect of PA within schools. Several neural mechanisms are suggested to explain the observed improvements in executive function after PA, such as the importance of brain-derived neurotrophic factor on synaptogenesis, the expression of human growth factors, the activated release of catecholamines, and increased blood lactate levels. The ensuing descriptive review demonstrates the current understanding of the effects of acute PA on childhood brain and cognition and may serve as a basis for understanding PA-induced improvements in academic achievement. INTRODUCTION In an era where physical inactivity has become a global pandemic (1), adverse effects have been observed not only for children’s physical health (2) but also their psychosocial well-being (3). Only 1/3 of boys and 1/5 of girls in Western countries are physically active at the recommended levels to optimize their health (i.e., >60min of daily moderate to vigorous physical activity (PA); (4)). The shift to a more sedentary lifestyle is contrary to our evolution as a physically active species; thus, our genetic makeup is maladapted to the sedentary lifestyle of today (5,6). As such, sedentary behavior represents a physiological disjunction from healthy (i.e., physically active) behaviors and has implications for poorer cognitive and brain health (7).

Influence of Physical Activity on Elementary School Children: Challenges and Practice 体育活动对小学生的影响:挑战与实践

INTRODUCTION Participation in physical activity (PA) is an important determinant of health and is associated with a wide range of physical and psychosocial benefits. The Centers for Disease Control and Prevention (CDC) recommends that children obtain at least 60min or more of moderate to vigorous PA (MVPA) daily; however, only 21.6%of children and adolescents 6 to 19 yr of age attain 60 or more minutes of MVPA on five or more days of the week. Children spend up to half of their waking hours in school; therefore, from a population-based approach, schools provide the best opportunity to increase PA among the nation’s youth (1). Comprehensive School Physical Activity Programs (CSPAP) have been recommended by the CDC/Society for Health and Physical Educators and endorsed by the Institute of Medicine (1) for increasing MVPA in children (2). These programs supplement physical education (PE) with PA throughout the day and emphasize involvement of school staff, the participants’ immediate family, and the wider community. However, evidence regarding the effectiveness of CSPAP for increasing PA in children is limited and conflicting (2–8). The National Association for Sport andPhysical Education recommends that elementary schools provide 150 min and secondary schools provide 225min of PE eachweek (9). However, very few schools require daily PE or provide the amount of PA recommended by the CDC (10) and the Institute of Medicine (11). To develop successful strategies to engage elementary-aged children in PA, it is necessary to understand the current challenges associated with the delivery of PA in the school and the positive outcomes associated with PA practice or delivery. This special issue of the Translational Journal of the American College of Sports Medicinewill provide perspectives on both the positive outcomes (cognition, academic achievement, and on-task behavior) and challenges (built environment, school PA policy, teacher implementation/ compliance, and teacher reflections) of implementing CSPAP interventions in elementary schools.
引言参加体育活动是健康的重要决定因素,与广泛的身体和心理社会益处有关。美国疾病控制与预防中心(CDC)建议儿童每天至少接受60分钟或以上的中度至剧烈PA(MVPA);然而,在6至19岁的儿童和青少年中,只有21.6%的人在一周中的五天或五天以上达到60分钟或60分钟以上的MVPA。孩子们醒着的时间有一半是在学校度过的;因此,从基于人口的方法来看,学校提供了增加全国青年PA的最佳机会(1)。美国疾病控制与预防中心/健康与体育教育学会推荐了综合学校体育活动计划(CSPAP),并得到了医学研究所的认可(1),以提高儿童的MVPA(2)。这些项目用PA全天补充体育(PE),并强调学校工作人员、参与者的直系亲属和更广泛的社区的参与。然而,关于CSPAP在增加儿童PA方面的有效性的证据是有限和矛盾的(2-8)。全国体育协会建议小学每周提供150分钟的体育课,中学每周提供225分钟的体育课程(9)。然而,很少有学校要求每天进行体育锻炼或提供美国疾病控制与预防中心(10)和医学研究所(11)建议的PA量。为了制定成功的策略,让小学年龄的儿童参与PA,有必要了解目前与学校提供PA相关的挑战,以及与PA实践或提供相关的积极成果。这期《美国运动医学院转化杂志》特刊将提供关于在小学实施CSPAP干预措施的积极成果(认知、学业成绩和任务行为)和挑战(构建环境、学校PA政策、教师实施/遵守和教师反思)的观点。

The increasing evidence about CBPA ’ s benefits for students indicates that it should be considered a best practice for elementary schools (2,3). However, given the low prevalence of use across the nation, it seems warranted to mo-bilize efforts to increase the number of classroom teachers who use CBPA and the consistency with which they do so. Yet, many questions remain about how best to encourage teachers ’ implementation of CBPA. This article reviews previous work exploring teacher-level implementation, including consideration of how CBPA implementation is measured and what is known about factors associated with implementation. We discuss interventions and potential innovations to support increased rates of implementation and sustained use of CBPA among classroom teachers. Our review of published evidence is supplemented with examples from our own work over the past 4 yr on the Physically Active Classrooms Energize! (PACE) project at Boise State University, which is supported by a research grant from the Institute of Education Sciences. On the PACE project, ABSTRACT Research exploring factors related to teachers ’ implementation of classroom-based physical activity (CBPA) has increased in recent years. This article highlights key findings from the literature about the implementation and maintenance of CBPA by classroom teachers. The authors provide an overview of the literature examining CBPA implementation from an implementation science perspective. Topics addressed include methods for measuring implementation, characteristics of CBPA resources, and predictors of teachers ’ implementation of CBPA. Findings from the narrative review are presented in tandem with insights from the authors ’ work during a grant-funded project examining strategies to improve CBPA implementation in elementary schools. Many off-the-shelf resources for CBPA implementation exist, with varying degrees of implementation support. Studies have used a variety of methods to measure implementation, mostly focused on teacher self-report. Few studies have provided evidence regarding long-term use of CBPA, but those that do report decreased implementation rates over time. A robust body of research examining CBPA implementation facilitators and barriers shows that organizational-level support from district and school administrators is crucial for successful implementation. Leadership buy-in is crucial for the implementation of policies and practices in schools, such as CBPA initiatives. Approaches that are embedded within school systems, such as communities of practice and coaching from school champions, have potential for improving implementation. designed implementation to increase how many teachers within a school provide regular CBPA to their students in the recommended To organize these findings, we use a framework for con- ceptualizing the implementation of CBPA in classrooms.
越来越多关于CBPA对学生有益的证据表明,它应该被认为是小学的最佳实践(2,3)。然而,鉴于全国范围内使用CBPA的普及率较低,似乎有必要动员努力增加使用CBPA的课堂教师的数量,并提高他们使用CBPA的一致性。然而,如何最好地鼓励教师实施CBPA仍然存在许多问题。本文回顾了以前探索教师级实施的工作,包括考虑如何衡量CBPA实施以及与实施相关的已知因素。我们讨论了干预措施和潜在的创新,以支持在课堂教师中提高实施和持续使用CBPA的率。我们对已发表的证据进行了回顾,并补充了我们自己在过去4年里对“身体活跃的教室激励!”(PACE)项目,该项目得到了教育科学研究所的研究资助。近年来,对教师实施课堂体育活动(CBPA)相关因素的研究越来越多。本文重点介绍了课堂教师实施和维持CBPA的主要研究成果。作者从实施科学的角度概述了研究CBPA实施的文献。讨论的主题包括测量实施的方法、CBPA资源的特征以及教师实施CBPA的预测因素。叙述性审查的结果与作者在一个资助项目中研究改善小学实施CBPA策略的工作见解相结合。存在许多现成的CBPA实现资源,具有不同程度的实现支持。研究使用了多种方法来衡量实施情况,主要集中在教师的自我报告上。很少有研究提供长期使用CBPA的证据,但那些确实报告了执行率随着时间的推移而下降。对CBPA实施的促进因素和障碍进行的大量研究表明,来自地区和学校管理者的组织层面的支持对成功实施至关重要。领导力的认同对于学校政策和实践的实施至关重要,例如CBPA倡议。嵌入学校系统的方法,如实践社区和学校冠军的指导,具有改进实施的潜力。为了组织这些发现,我们使用了一个框架来概念化CBPA在课堂上的实施。
