Abstract

The purpose of this study was to observe the effects of a progressive aerobic training program on hemoglobin concentration (Hb), hematocrit (Hct), red blood cell (RBC) count, mean RBC size (MCV), and mean corpuscular hemoglobin (MCH) of college women (N = 19). Training consisted of jogging (3 × week) one mile per session (Week 1) with a progressive increase in duration to five miles per session (Week 9). Training intensity elicited heart rates between 165–185 beats per minute. Blood samples were taken before training and after approximately two, five, seven, and nine weeks. Maximal oxygen uptake (ml/kg · min^?1) increased significantly during training from 41.2 ± 0.7 ( ± SE) to 44.7 ± 0.7. Initial values of Hb, Hct, RBC count, MCV, and MCH were 14.7 ± 0.13 g/dl, 40.4 ± 0.46%, 4.5 ± 0.5 × 10⁶/mm³, 89.0 ± 1.1/μ³, and 32.4 ± 0.4 μμg respectively. Orthogonal polynominal regression indicated significant decreasing quadratic trends for Hb, Hct, and RBC count, a significant cubic trend for MCV, and no change in MCH during training. Despite the initial trends, values that changed did return to near pretraining levels by the end of the nine-week program. Values for all blood parameters remained within normal ranges throughout the study. These data suggest that although aerobic training of increasing intensity in young women may be accompanied initially by decreases in Hb, Hct, and RBC count and an increase in MCV, these changes are only transitory. If such changes result from RBC destruction rather than hemodilution, the return to hematopoietic balance could impose a draw on body iron stores.  相似文献   

Instructional Climates in Preschool Children Who Are At-Risk. Part II     

Leah E. Robinson  Mary E. Rudisill  Jacqueline D. Goodway 《Research quarterly for exercise and sport》2013,84(3):543-551

In Part II of this study, we examined the effect of two 9-week instructional climates (low-autonomy [LA] and mastery motivational climate [MMC]) on perceived physical competence (PPC) in preschoolers (N = 117). Participants were randomly assigned to an LA, MMC, or comparison group. PPC was assessed by a pretest, posttest, and retention test with the Pictorial Scale of Perceived Competence and Social Acceptance. A significant Treatment × Time interaction (p < .001) was present, supporting that MMC participants reported significantly higher PPC scores over time, while no positive changes were present in LA and comparison participants. The results show that an MMC leads to psychological benefits related to achievement motivation. These findings should encourage early childhood educators to consider the effect of instructional climates on children's self-perception.  相似文献   

Evaluation of the Physical Activity and Public Health Course for Practitioners     

Kelly R. Evenson  David R. Brown  Emily Pearce  Ricky Camplain  Jan Jernigan  Jacqueline Epping 《Research quarterly for exercise and sport》2013,84(2):207-213

Purpose: From 1996 to 2013, a 6-day Physical Activity and Public Health Course for Practitioners has been offered yearly in the United States. An evaluation was conducted to assess the impact of the course on building public health capacity for physical activity and on shaping the physical activity and public health careers of fellows since taking the courses. Method: An evaluation quantified time that fellows spent in different course offerings and surveyed fellows. Results: From 1996 to 2012, 410 fellows attended the course, and in 2013, 186 participated in the Web-based survey (56% response rate). The number of fellows attending the course ranged from 15 to 33 yearly. From 1996 to 2012, the course averaged 38 hr of instructional time that included topics on interventions and environment/policy work to increase physical activity, program evaluation, public health research, and health disparities. The course included consultations, collaborative work, and field-based experiences. Fellows who participated in the survey agreed that the course had a positive impact on the physical activity research or practice work they did (98%), met their expectations (96%), helped them with research/practice collaborations with other physical activity professionals (96%), assisted them in conducting higher-quality interventions/programs (95%), helped increase their professional networking in the field (93%), and had a positive impact on other work they did (91%). Following the course, 66% and 56% had further contact with faculty and other fellows, respectively. Conclusion: The Physical Activity and Public Health Course for Practitioners made important contributions toward building the capacity of physical activity and public health practitioners.  相似文献

Laboratory versus field testing in cricket bowling: A review of current and past practice in modelling techniques     

Bruce Elliott  Jacqueline Alderson 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(1):99-108

In cricket bowling, the reconstruction of elbow angle data is of utmost importance to the bowling versus throwing argument. This paper reviews system and modelling errors inherent in three-dimensional reconstruction processes with respect to the elbow extension tolerance set by the International Cricket Council. An understanding of these factors will enable more informed decisions about the choice of in-field versus laboratory testing in the calculation of elbow extension during bowling in cricket. Although there is a paucity of objective data related to in-field and laboratory testing, biomechanists must be guided by the greater accuracy of opto-reflective than video-based systems and so testing, at least for the present, should be conducted in a laboratory setting.  相似文献   

Service Learning Pedagogies to Promote Student Learning in Occupational Therapy Education     

Deshini Naidoo  Jacqueline M. van Wyk  Rubby Dhunpath 《Africa Education Review》2019,16(1):106-124

The centrality of service learning in the development of students’ professional practice has received worldwide attention. Exposure to appropriately designed service learning experience determines the acquisition of graduate attributes. This article addresses a study in which the key question was: What methods and strategies do students and their clinical supervisors find beneficial in improving their learning experiences during service learning placements? Drawing on the views and experiences of a group of final year occupational therapy (OT) students and their supervisors, the initial focus is on concepts in learning relevant to service learning and professional development, including Vygotsky's zone of proximal development (ZPD), the capability approach and collaborative and peer assisted learning. This is followed by an overview of the methodology and an analysis of the students’ and clinical supervisors’ experiences during service learning. The discussion focuses on the implications of the study findings for practice within a service learning context to enhance the alignment of institutional practices with students’ needs.  相似文献   

Rhyme generation in deaf students: the effect of exposure to cued speech   总被引：1，自引：0，他引：1  

LaSasso C  Crain K  Leybaert J 《Journal of deaf studies and deaf education》2003,8(3):250-270

This study compares the rhyme-generation ability of deaf participants with severe to profound hearing losses from cued speech (CS) and non-cued speech (NCS) backgrounds with a hearing comparison group for consistent orthography-to-phonology (O-P) rhyming elements, or rimes (e.g., -ail in sail is always pronounced the same), and inconsistent orthography-to-phonology (I-O-P) rhyming elements where the orthographic rime (e.g., -ear) has different pronunciations in words such as bear, and rear. Rhyming accuracy was better for O-P target words than for I-O-P target words. The performance of the deaf participants from CS backgrounds, although falling between that of the hearing and the NCS groups, did not differ significantly from that of the hearing group. By contrast, the performance of the NCS group was lower than that of the hearing group. Hearing and CS participants produced more orthographically different responses (e.g., blue-few), whereas participants from the NCS group produced more responses that are orthographically similar (e.g., blue-true), indicating that the hearing and CS groups rely more on phonology and the NCS group more on spelling to generate rhymes. The results support the use of cued speech for developing phonological abilities of deaf students to promote their reading abilities.  相似文献   

Gender and sexuality diversity and schooling: progressive mothers speak out     

Tania Ferfolja  Jacqueline Ullman 《Sex education》2017,17(3):348-362

Abstract

Although social acceptance of gender and sexuality diversity is growing in Australian society, in schools, visibility and inclusion of knowledge pertaining to those who are gender- and/or sexuality-diverse, such as lesbians, gay men and transgender people, remain marginalised. This may be due, in part, to a belief that parents are opposed to such content inclusions in their children’s education; yet, virtually no Australian research supports this belief nor have parental perspectives on gender and sexuality diversity inclusion been specifically examined. This paper draws on a broader research study that examined New South Wales parents’ perceptions about the visibility of gender and sexuality diversity and the inclusion or exclusion of related content in school curriculum. It focuses on one particular focus group comprised of only mothers who lived in a specific enclave of Sydney known for its gender and sexuality diversity. The discussion highlights their awareness of gender and sexuality diversity and the dynamics surrounding it; and their perceptions of local school approaches to, and limitations around, gender and sexuality diversity in school curricula, policy and practices, despite potential support for it.  相似文献

Responsibility for nurturing a child’s wellbeing: teachers teaching mindfulness with children     

Nicole Jacqueline Albrecht 《Asia-Pacific Journal of Teacher Education》2019,47(5):487-507

ABSTRACT

A thriving and evolving pool of research and commentary is emerging in relation to the integration of mindfulness techniques in school and out-of-school settings. In the current study the author explored how experienced mindbody wellness instructors make sense of teaching children mindfulness. The methodology of Interpretative Phenomenological Analysis was used to interview eight teachers teaching mindfulness with children from the United States and Australia. Four thematic categories emerged from the analysis and in this article the author discusses findings related to the theme of, Responsibility for Nurturing a Child’s Wellbeing. It was discovered that having a holistic-wellness-orientated vision was an important aspect of how teachers made sense of mindfulness instruction. The findings showed that teaching children mindfulness has the capacity to raise academic performance while synergistically enhancing a child’s spiritual, environmental, emotional, social, creative and physical wellbeing. It is recommended that mindfulness teacher training programs be established in universities to better prepare students to meet the demands of 21^st Century education.  相似文献
