The Meaning of Physical Literacy for Instructors of Children Experiencing Disability, from an Ecological Systems Perspective.

With the rapid and widespread uptake of physical literacy (PL), there is potential for instructors to devalue participation of children who experience disability. The aim of the investigation was to understand how instructors who facilitate physical activity for children experiencing disability make sense of PL, and more specifically, how these instructors bring meaning to PL. Using interpretive phenomenological analysis, six instructors engaged in individual, semi-structured interviews. The study rationale was underpinned by the conceptual framework of ecological systems theory, which provided a foundation for the research, guided the structure of the interview guide, and facilitated a reflexive interpretation of the findings. Four themes were generated: Recognizing unique embodiments, The importance of context, Beyond physical competence, and Navigating PL's dominant discourse. The instructors' meaning of PL, impacted by relational and environmental influences, reflected the importance of movement skill development, while also embracing diverse embodiment and pedagogical flexibility by giving value to exploratory play, partial participation, family involvement, and willingness to abandon rigid lessons plans.

Feasibility and Acceptability of Virtual Implementation of a Sexual Reproductive Health Teen Pregnancy Prevention Program for Native Youth.

American Indian/Alaska Native (Native) youth face high rates of substance use, teen pregnancy and sexually transmitted infections. In response to the COVID-19 pandemic, Respecting the Circle of Life (RCL), a sexual reproductive health and teen pregnancy prevention program for Native youth and their trusted adult, was adapted and delivered in a virtual format with Native youth in a rural, reservation-based Native community. This manuscript describes the adaptation process, feasibility, and acceptability of virtual program implementation. The manuscript describes the process of rapidly shifting the RCL program into a virtual format. In addition, a mixed-methods process evaluation of implementation forms, program feedback forms, in-depth interviews with participants, and staff debriefing sessions was completed. Results show virtual implementation of RCL is both feasible and acceptable for Native youth and their trusted adults. A key benefit of virtual implementation is the flexibility in scheduling and ability to have smaller groups of youth, which offers greater privacy for youth participants compared to in-person implementation with larger groups. However, internet connectivity did present a challenge for virtual implementation. Ultimately, sexual and reproductive health programs seeking to reach Native youth and families should consider virtual implementation methods, both during and outside of pandemic situations.

Physical Literacy for Children Labeled With Autism Spectrum Disorder: Mothers' Experiences of Ableism, Exclusion, and Trauma.

Countering the declining physical activity patterns of children labeled with autism spectrum disorder (ASD) has gained considerable research attention given its impact on health and quality of life. The purpose of this study was to explore how parents of children labeled with ASD understand the concept of physical literacy, based on their children's participation in community-based physical activity programs. Using interpretive phenomenological analysis, six mothers of children labeled with ASD participated in one-on-one semistructured interviews. The conceptual framework of ecological systems theory supported the rationale for the study purpose, provided structure for the interview guide, and offered a reflexive context for interpretation. Four themes were generated from the thematic analysis: From embodied movement to normative skill expectations, Be flexible, not rigid, Systematic exclusion, and Valuable? . . . Absolutely! Despite experiences of marginalization, exclusion, and trauma within physical activity programs, mothers valued physical literacy development for their children given the positive outcomes of increasing family connections, engagement with peers, and enhanced wellness.

An Exploratory Study of Teachers' Experiences in Physical Education With Children Thought to Have Developmental Coordination Disorder.

Teachers can create supportive conditions in physical education to mitigate experiences of stress for children with developmental coordination disorder (DCD); however, most are unfamiliar with DCD and lack adequate training to instruct children with impairments. The purpose of this study was to explore teachers' perceptions of and interactions in physical education with children thought to demonstrate functional difficulties associated with DCD. A semistructured interview was conducted with 12 teachers across all elementary years with diverse backgrounds and thematically analyzed. Four themes were produced. Teachers (a) had differing views on the etiology of children's movement difficulties, though (b) all recognized a range of difficulties children demonstrated. They (c) believed it was their role to facilitate positive experiences for these children in physical education but (d) experienced challenges in doing so. Training that increases teachers' knowledge of and abilities to address the needs of children thought to have DCD is warranted.

Experiences in Physical Education for Children at Risk for Developmental Coordination Disorder.

Children with developmental coordination disorder (DCD) may experience stress in physical activity contexts due to emphasis on their poor motor skills. The purpose of this study was to explore the lived experiences of children at risk for DCD in physical education in order to develop a deeper understanding about what they experience as stress and how they cope with it. Using interpretative phenomenological analysis, six children in Grades 4-6 participated in two semistructured interviews. A motivational (and developmental) stress and coping theory informed interpretation of the three themes that described the children's experiences: (a) they hurt me-psychological and physical harm sustained from peers, (b) it's hard for me-difficulties encountered in activities, and (c) I have to-pressure to meet the teacher's demands. Although the children at risk for DCD were confronted with various stressors in physical education, they coped more adaptively when social support was provided.

Conceptualizing Obesity as a Chronic Disease: An Interview With Dr. Arya Sharma.

Dr. Arya M. Sharma challenges the conventional wisdom of relying simply on "lifestyle" approaches involving exercise, diet, and behavioral interventions for managing obesity, suggesting that people living with obesity should receive comprehensive medical interventions similar to the approach taken for other chronic diseases such as Type 2 diabetes or hypertension. He purports that the stigma-inducing focus on self-failing (e.g., coping through food, laziness, lack of self-regulation) does not address biological processes that make obesity a lifelong problem for which there is no easy solution. Interdisciplinary approaches to obesity are advocated, including that of adapted physical activity. Physical activity has multifaceted impacts beyond increasing caloric expenditure, including improved sleep, better mood, increased energy levels, enhanced self-esteem, reduced stress, and an enhanced sense of well-being. The interview with Dr. Sharma, transcribed from a keynote address delivered at the North American Adapted Physical Activity Symposium on September 22, 2016, in Edmonton, AB, Canada, outlines his rationale for approaching obesity as a chronic disease.

A Documentary Analysis of Abstracts Presented in European Congresses on Adapted Physical Activity.

The purpose of the study was to identify trends in research abstracts published in the books of abstracts of the European Congress of Adapted Physical Activity from 2004 to 2012. A documentary analysis of the contents of 459 abstracts was completed. Data were coded based on subcategories used in a previous study by Zhang, deLisle, and Chen (2006) and by Porretta and Sherrill (2005): number of authors, data source, sample size, type of disability, data analyses, type of study, and focus of study. Descriptive statistics calculated for each subcategory revealed an overall picture of the state and trends of scientific inquiry in adapted physical activity research in Europe.

Youth sport experiences of individuals with attention deficit/hyperactivity disorder.

The purpose of this study was to explore youth sport experiences of individuals with attention deficit/hyperactivity disorder (ADHD). Participants were 6 males (mean age=22.7 yr) with ADHD who had played 3 or more seasons in team sports during adolescence. Following interpretive phenomenological analysis methodology, each participant completed 2 semistructured interviews. Findings showed that symptoms of ADHD hampered participants' experiences and led to negative interpersonal and performance-related consequences. On the other hand, participants reported social and stress/energy-release benefits arising from their experiences in sport. Their experiences were therefore complex, and some findings relating to social interactions appeared contradictory (e.g., negative interpersonal experiences vs. social benefits). Supportive coaches, understanding teammates, and personal coping strategies were key factors that enabled participants to realize benefits and, to some degree, mitigate negative consequences associated with their participation in sport.

Smooth muscle alpha-actin expression in endothelial cells derived from CD34+ human cord blood cells.

Human fetal cord blood contains subsets of mononuclear cells with the potential to form both hematological and endothelial cells. Vascular progenitor cells, which can produce all three elements of mature blood vessels, including smooth muscle, have been identified in animals. We hypothesized that similar multipotential progenitor cells exist in humans and used the expression of alpha-smooth muscle actin (alpha-SMA) to identify such cells in fetal cord blood. Mononuclear cell preparations were isolated from human umbilical cord blood and CD34(+) and CD133(+) cells obtained by magnetic bead separation. Isolated cells were cultured on fibronectin-coated dishes with medium containing vascular endothelial growth factor, basic fibroblast growth factor, and insulin-like growth factor. mRNA was extracted, and the expression of alpha-SMA and a number of endothelial cell markers (VEGFR-2, vWF, eNOS, VE-Cadhein, PECAM-1 and Tie-2) was determined by reverse transcriptase-PCR techniques. Human umbilical vein endothelial cells (HUVECs) were used as positive controls. Freshly isolated CD34(+) and CD133(+) cells expressed all endothelial cell markers, but did not express alpha-SMA. HUVECs expressed alpha-SMA. Following 4 weeks of culture, CD34(+) isolates produced morphologically endothelial-like cells that expressed both endothelial cell markers and alpha-SMA. CD133(+) cells failed to produce morphological endothelial-like cells but expressed a range of endothelial markers. However, they did not express alpha-SMA. Following culture in an endothelial cell-promoting environment, CD34(+), but not CD133(+), isolates produced endothelial-like cells that expressed alpha-SMA. Human fetal cord blood contains a population of cells that may differentiate toward both an endothelial and a smooth muscle phenotype in culture.
