The sample included 200 older adults (113 women). To assess daily walking time, participants responded to the EPIC-PAQ in an interview and wore a portable gait analysis system and physical activity monitor for 48 consecutive hours in free-living condition.
Results indicated that the mean of bias between the EPIC-PAQ and objetive measurement was ?64.6 min/day. Also, the correlation was low compared to an objective measurement (rho = 0.196) and was positively correlated with the time spent at speeds below 2.5 mph but the correlation was low (slow walking rho = 0.154 and pace walking rho = 0.163).
The EPIC-PAQ shows low correlations with the objective measurement of walking time, that suggests it may be inaccurate and affecting the estimate of the EPIC-PAQ’s PA energy expenditure in this age group. 相似文献
Methods: Cohort of 2,851 individuals aged ≥ 60 from Spain. Mortality was ascertain from 2003 up to July 2013. Patterns of PA, SB and sleeping were identified by factor analysis.
Results: During follow-up, 1,145 deaths occurred. The first pattern, named “sedentary and non-active pattern”, was characterized by long sleeping or lying time, and not doing even light PA (household chores or walking). The second pattern was named “active and non-sedentary pattern”, and was characterized long time devoted to vigorous activities, long walking time, and short seating time. Compared to those in the first quartile of the “sedentary and non-active pattern”, those in the highest quartile showed a 71% higher mortality (HR: 1.71; 95%CI: 1.42–2.07; p-trend:<0.001); it corresponds to being 6-year older. By contrast, being in the highest versus the lowest quartile of the “active and non-sedentary pattern” was associated with a 32% lower mortality (HR: 0.68: 0.57–0.82; p-trend:<0.001); it corresponds to being 4-year younger.
Conclusion: The “sedentary and non-active” pattern had a large impact on mortality. The “active and non-sedentary” pattern showed an opposite and slightly lower association. 相似文献
Method: 19 footballers (U12 yrs) participated in 14 training sessions, spread over three phases: Pre-intervention, Intervention, Retention. The intervention was based on Small-Sided and Conditioned Games. We assessed progress during the intervention phase at two different points: intermediate and final. The GPET instrument was used to analyse the DM and P during the completion of 3208 passes in the intervention.
Results: Results shown significant improvements in the DM and P after the intermediate and final points of the acquisition phase. Moreover, significantly higher values were also obtained in both variables in the retention, compared to the pre-intervention phase.
Conclusion: Results indicated that the NLP intervention programme was effective in improving both aspects of team games performance in youth players, with effects consolidated over time. 相似文献
This study was conducted with 415 children (9.1 ± 0.4 years) and 853 adolescents (13.6 ± 1.6 years) in Spain during 2011–2012. Total ST and PA were assessed by accelerometry. Leisure-time spent in twelve sedentary behaviours was self-reported. Adiposity and physical fitness was measured following the ALPHA battery for youth.
Total accelerometer-based ST was positively associated with global adiposity score in children, and negatively associated with global physical fitness score in children and adolescents; but relationships were not independent of PA. PA mediated all associations of accelerometer-based and self-reported ST with adiposity or physical fitness in children. Conversely, screen-, educational-, social-, and other-based ST were negatively related to physical fitness in adolescents, independently of PA.
These findings give an impetus to developing effective strategies for specifically promoting PA in children and for increasing PA while reducing ST in adolescents in order to produce improvements on adiposity and physical fitness. 相似文献
Purpose: This study was funded by a national government funded organisation and led by a university in collaboration with a secondary PE specialist and two primary teachers. The purpose was to develop a replicable PE-CPD process to improve primary generalist teachers’ PE pedagogy by transferring their positive pedagogy from the classroom to the PE setting.
Participants: The participants were two Year 3 (age 7–8 years) primary classroom teachers from the same school and one secondary PE specialist teacher who acted as a mentor.
Research approach: A collaborative professional learning (CPL) approach was utilised to develop the PE-CPD intervention process. CPL involves teachers and other members of a profession working together to improve their own and others’ learning on pedagogic issues. A six-week needs assessment phase was completed through classroom and PE lesson observations to identify key areas for development in the PE-CPD process over the duration of a 23 week intervention.
Data collection and analysis: Reflective logs, structured lesson observations and teacher interviews were used to collect the data during the PE-CPD intervention. Inductive and deductive qualitative thematic analysis was used to analyse and interpret the data.
Findings: A number of key themes were generated during the data analysis including the transfer of positive pedagogy from the classroom to the PE setting and the implementation of effective pedagogic principles including the setting of clear learning outcomes, differentiation and inclusion to enhance the PE pedagogy. A key element to the success of the intervention was the trusting relationships built by the secondary PE specialist with the primary teachers. Further, the results also revealed the importance of CPL in ensuring rigorous, evidence-based PE-CPD and providing the time and support required for fundamental sustainable changes in practice, which can endure beyond the life of the research project.
Conclusion: The major contribution of this paper is in demonstrating the potential of CPL between national organisations, universities, secondary and primary schools to improve the PE pedagogy of primary generalist teachers. Future research should build upon the findings in this study and replicate this PE-CPD approach with other classes and schools. 相似文献
Purpose: The aim of this study is to provide in-depth perspectives on need supportive training through examination of GTAs reflections of the training process.
Participants and setting: Fourteen GTAs from a university physical activity and healthful living program were recruited for this study, but two dropped out. All participants taught one of the following courses: aerobics, basketball, body conditioning, bowling, flag football, golf, racquetball, soccer, tennis, ultimate frisbee, volleyball, or yoga.
Data collection: Teaching reflections were written by participants at the end of a year-long training program.
Data analyses: Written reflections completed by the GTAs were analyzed via content analysis. Data were organized by how strategies were implemented, most/least successful use of the strategies, and adherence to the training. Once organized, the data was examined by two different researchers independently and themes were shared with participants as part of the member checking process. Searches for negative cases were utilized during the analysis process as well.
Findings: Across the data, it was determined that the GTAs felt the training to be beneficial, influencing much of how they worked with students. Results suggested that GTAs found several ways to implement the reviewed need supportive teaching strategies, including giving students the choice of activities and group membership. They were also able to better respond to students’ negative affect and give explanatory rationales. Goal setting was a consistently used strategy by the GTAs; however, it was cited as one of the least successful strategies due to the inability to effectively follow-up on the goals made during classes with the students. Additionally, it was noted that the GTAs had difficulties with devising their own ways of implementing the strategies and relied heavily on the examples that were provided during their training sessions.
Conclusion: In better understanding, the perceptions of GTAs who engage in need supportive training programs, researchers can better gauge the effectiveness of such programs and how they can be improved. Future research should focus on how to help GTAs to engage in more creative ways of using need supportive teaching strategies in physical activity environments. 相似文献
Participants (n = 48) wore Fitbit Flex or Flex2 monitors on each wrist for three days. T tests, equivalence tests, and correlations were used to compare steps, Calories, distance, active minutes, and sleep duration recorded by dominant and nondominant wrist-worn monitors and effect sizes and mean absolute and percent difference were calculated.
The nondominant Flex2 monitor was not equivalent to the dominant wrist-worn monitor and recorded significantly more steps/day (absolute difference = 708), miles/day (0.3), and active minutes/day (7.9) than the dominant Flex2 monitor. For all variables, nondominant and dominant output was correlated (r>0.75).
Nondominant and dominant Flex2 monitors are significantly different, but there were small differences for Flex monitors. Research should investigate effects on behavior and replicate findings using other monitors. 相似文献
Methods: Youth players 11 (n = 62, born 1992, observed December 2003) and 13 (n = 50, born 1990, observed April 2004) years were grouped by BQ. Baseline data included stature, weight, maturity status, functional capacities, soccer skills, goal orientation, and coach evaluation of potential. Playing status in soccer in 2006 and 2014 was also available. Baseline characteristics and subsequent playing status were compared by BQ.
Results: Baseline characteristics did not differ by BQ except for age and percentage of predicted adult height. Though not significant, coaches tended to rate players in BQ1as higher in potential. For those competing in soccer as adults, BQ2 (4), BQ3 (5) and BQ4 (2) were represented among players11 years, and BQ1 (3), BQ2 (2), BQ3 (1) and BQ4 (4) among players 13 years.
Conclusion: Although limited to small numbers, differences among players by BQ were inconsistent. The results indicate a need to extend potential explanations of the RAE to include behavioral variables, coaches, training environment, and perhaps the culture of the sport. 相似文献
For risk factors, prospective cohort studies (n > 20) with a statistical analysis for injured and non-injured players were included and studies with a RCT design for prevention programs. Downs&Black checklist was assessed for risk of bias for risk factors. From a total of 4067 articles, five articles met our inclusion criteria for risk factors. No studies on effectiveness of prevention programs were identified. Quality of studies included varied from fair to excellent.
Best evidence synthesis revealed moderate evidence for previous injury regardless of body location in general and fewer years of tennis experience for the occurrence of upper extremity injuries. Moderate evidence was found for lower back injuries, a previous back injury, playing >6hours/week and low lateral flexion of the neck for risk factors. Limited evidence was found for male gender as a risk factor.
The risk factors identified can assist clinicians in developing prevention-strategies. Further studies should focus on risk factor evaluation in recreational adult tennis players. 相似文献
Purpose: This study aimed to explore what students are likely to experience during MA training. In particular, we give an insight into the thoughts and expectations of some of the MA most experienced practitioner-teachers. In identifying these facets of the student experience, future research may then be able to determine which facets are most effective in improving student self-regulation and wellbeing.
Design: Four martial arts instructors from a broad range of disciplines, and (each) with over 30 years of teaching experience, were interviewed to gain insights into the typical student experience of martial arts training.
Conclusions: Thematic analysis revealed ten components/ facets of the student experience of training. These components belonged to the three broader areas of physical experience, social expectations, and mindful training. These components if validated by future research may be used to form a quantitative survey measure of the MA student experience, and may ultimately allow researchers and practitioners to identify the more functional facets of MA training in relation to improving the student experience and students’ self-regulation skills. 相似文献
Methods: 679 males and females (mean age among men = 66.7 ± 9.3 years old and mean age among women = 64.8 ± 8.9 years old) composed the study sample. Sports participation was assessed using Baecke’s questionnaire, which considers intensity, duration and previous engagement. Medical records were used to identify the cause of the death. Cox regression analysis was performed to determine the independent associations of exercise components and mortality.
Results: Participants that reported exercising at moderate-vigorous intensity (Moderate/vigorous: 4.1% versus None/light: 10.3% [p-value = 0.012]; HR = 0.42 [0.1 to 0.94)] and for more than four months (≥4 months: 5.3% versus <4 months: 10.2% [p-value = 0.038]; HR = 0.47 [0.24 to 0.94]) had lower mortality risk. The percentage of survival according to all-cause mortality was significantly higher for participants engaged in sports at moderate-vigorous intensity (p-value = 0.014), as well as for those engaged in sports for periods superior than four months (p-value = 0.036).
Conclusion: We found higher percentage of survival among adults engaged in sports at moderate-vigorous intensity and with at least four months of previous engagement. 相似文献
Methods: Twelve competitive male cyclists completed an incremental test to exhaustion, a FTP test and 4–5 self-paced TT bouts on a stationary bike within the lab, and a 16.1 km road TT, using mobile power meters.
Results: CP and W? derived from the power-duration relationship closely predicted TT performance. The 16.1-km road TT completion time (26.7 ± 2.2 min) was not significantly different from and was significantly correlated with the predicted time-to-completion (27.5 ± 3.3 min, r = 0.89, P < 0.01). CP and FTP were not significantly different (275 ± 40 W vs. 278 ± 42 W, P > 0.05); however, the limits of agreement between CP and FTP were 30 to -36 W.
Discussion: The findings of this study indicate that CP and W? determined using mobile power meters during maximal, self-paced TT prediction trials can be used to accurately predict 16.1-km cycling performance, supporting the application of the CP and W? for performance prediction. However, the limits of agreement were too large to consider FTP and CP interchangeable. 相似文献
Purpose: The purpose of this article is to consider whether PE pre-service teachers are trained during short training sessions aimed to discover new physical activities. We examine the influence of a scaffolding procedure (CLS design) on PE pre-service teachers’ knowledge, skills and self-efficacy in comparison to a CL and a DI experience. This leads to consider to what extent this instructional support provided by the instructor would help pre-service teachers to perceive themselves as self-efficacious to teach contents in PE.
Participants and design: After a pre-test, sixty-nine PE pre-service teachers were randomly assigned to one of the three following conditions: CL (14 males and 7 females); CLS (20 males and 8 females) or direct instruction condition (DI; 12 males and 8 females). For the training session a selected CL procedure (Jigsaw) [Aronson, Elliot, and Shelley Patnoe. 1997. The Jigsaw Classroom: Building Cooperation in the Classroom. 2nd ed. Wokingham: Addison-Wesley Educational]) was used to split CL and CLS participants into mixed-sex teams, whereas DI participants practiced the same exercises in dyads. According to the training conditions, the same instructor provided different information to participants along the three 2-hour instructional sessions with regard to: (a) warm-up (DI), (b) CL organization (CL), and (c) scaffolding integrated into a CL implementation (CLS).
Data collection: A Pre-test/post-test design was used to consider PE pre-service teacher’s motor skill, knowledge for practice, and self-efficacy improvements. The post-test also examined participants’ pedagogical knowledge.
Findings: The results showed that the participants in the three conditions progressed on performance, knowledge for practice, knowledge for teaching, and self-efficacy. Although no difference was found in self-efficacy between the three training conditions over time, significant differences appeared on pedagogical knowledge or/and motor skills with an advantage for the CL and CLS participants, respectively.
Conclusion: Although short training sessions dedicated to discovering new sports stay problematic for teacher professional development, implementing CL pre-service teacher training designs would be a relevant alternative. Instructional knowledge would be developed mainly when they have explicitly access to information concerning the teacher intervention. Nevertheless, such a scaffolding procedure integrated into CL training designs would need to be applied repeatedly to various physical activities to have an impact on pre-service teachers’ self-efficacy. 相似文献
Research design: This study utilized an exploratory multiple case study design (Yin 2003). The main premise of the case study method is to better understand complex educational and social phenomena, while retaining the holistic and meaningful particularities of real-life circumstances (Yin 2003). Teacher interviews and teacher shadowing were used to examine the experiences of PE teachers in high-poverty schools.
Findings: Results indicate that several psychological factors (relating to positive personality, motivation, focus, and perceived social and administrative support) protected the PE teachers in this inquiry from the potential negative effect of stressors by prompting their metacognitions and challenge appraisal. These processes promoted facilitative responses that proved to be key to developing and maintaining their capacities for resilience. The teachers demonstrated a sustained commitment to self-improvement and student success by implementing effective teaching practices.
Conclusion: The teachers in this study possessed strong individual dispositions and were able to demonstrate behaviors that facilitated an elevated level of resilience. School administrators must establish a strong culture of support to enable teacher resilience. Identifying ways to increase the resilience capacity of physical education teachers has the potential to decrease the concerns surrounding teacher attrition and increase job satisfaction for teachers working in high-poverty schools. Implications also indicate a need for physical education teacher education (PETE) programs to identify candidates with the individual dispositions that aid in resilience and provide them with experiences in high-poverty schools. This partnership may assist in minimizing the effects of reality shock oftentimes experienced by new teachers. 相似文献
Purpose: This study uses a conceptual framework on transfer of life skills to examine the role of life skills in an SBYD program. Research questions include: (1) how does the SBYD program integrate the teaching of life skills, (2) how do youth participants experience the life skills in the boxing program, and (3) how do youth participants perceive the life skills impact them beyond the program.
Methodology: This research took place at three community boxing academies in New Zealand. The three academies were selected because they are affiliated with a boxing program that is committed to implementing a life skills framework called the Passport to Success. Forty-one youth (31 boys, 10 girls) across the three sites participated in focus groups interviews about their experience in the program. Additionally, observations of program implementation documented the daily routines of each boxing academy. Using a qualitative case study design, inductive analysis and constant comparative methods were used to identify emergent themes.
Findings: Youth participants perceived life skills to be a foundational component of the boxing program. The life skills were presented to youth through the ‘Passport to Success’, a document featuring eight key life skills. The coaches focused on the Passport to Success in several ways, including setting an expectation that youth memorize the life skills to demonstrate their commitment. Several youth participants discussed learning valuable lessons around the life skills. Finally, youth were able to describe scenarios which demonstrated how the life skills connected with other areas of their lives.
Conclusion: Life skills implementation was guided by the Passport to Success and an expectation that youth develop positive relationships in the gym. A routine strategy for memorizing the Passport to Success provided a clear example of youth learning the meaning of life skills in the context of sports. The youth participants demonstrated cognitive connections in their explanation of the value of life skills beyond the boxing program. Using the conceptual framework on transfer [Jacobs and Wright 2018. “Transfer of Life Skills in Sport-Based Youth Development Programs: A Conceptual Framework Bridging Learning to Application.” Quest 70 (1): 81–99] helps to explain the cognitive connections youth participants make between life skills in a sports program and their application beyond sports. 相似文献
Purpose: The current article aims to provide a narrative summary of international research perspectives and findings regarding PE teachers’ attitudes and self-efficacy (SE) toward inclusion, as well as to develop a model for conducting further research.
Design: A narrative literature review was performed, based on a search of the databases SPORT Discus and MEDLINE (combined via EBSCO host and screened for peer-reviewed academic journals only), and Google Scholar. The search used the following terms: physical education teachers, inclusion, disability, and attitudes or SE. The narrative review begins with setting the scope of this topic via definitions and theoretical frameworks used to enable the understanding of attitudes and SE within inclusive PE. The Social Learning Theory (SLT) and the Theory of Planned Behavior (TPB) were outlined in order follow up with an explanation of the link between attitudes and SE. In the next section, the literature on attitudes and SE of PE teachers is presented. This section is comprised of subsections describing the development of instruments and their utilization in the field of study, as well as contextual variables influencing PE teachers’ attitudes and SE toward inclusion.
Findings: Seventy-five articles were included in total, of which 54 discussed research on teachers’ attitudes towards inclusive PE, 12 were related to research on teachers’ SE (three of which also included research on teachers’ attitudes towards inclusion), and 12 were considered reviews or viewpoints. The article ends with a model, including the following parts: background variables (regarding teachers’ personal attributes, school attributes, and disability attributes); moderating variables (attitude and SE); and, teachers’ behavior toward inclusion, all of which are interrelated and include a feedback loop. This model can be used for designing future research, as well as evidence-based interventions aimed at facilitating teacher training toward inclusion.
Summary for practitioners: From a practical point of view, educational inclusion practitioners should be aware of several factors influencing attitudes and/or SE while engaging in inclusion of children with disabilities in PE: (a) The teachers’ volume and type of experience with persons with disabilities at school, in the family or in the community; (b) The professional and academic training toward inclusion; (c) Individual factors, including gender; (d) School environmental factors, such as a process rather than performance orientation; and, finally, (e) The type and degree of disability. 相似文献
Purpose: This digital ethnographic study sought to describe one elementary school physical education (PE) teacher's attempt to employ transformative pedagogy (TP).
Method: Cochran-Smith's [1998. “Teaching for Social Change: Toward a Grounded Theory of Teacher Education.” In The International Handbook of Educational Change, edited by A. Hargreaves, A. Lieberman, M. Fullan, and D. Hopkins, 916–952. Netherlands: Kluwer Academic Publishers, 2004. Walking the Road: Race, Diversity, and Social Justice in Teacher Education. New York: Teachers College Press] pedagogical principles for social justice education (SJE) drove our data collection and analysis. Seven qualitative methods were employed to collect data about Harry's pedagogies, organizational structures, and the content he taught. These were formal and informal interviews, conversations, short films, document collection, social media accounts, and an electronic journal. Data were analyzed using both inductive and deductive methods [Patton 2015. Qualitative Research and Evaluation Methods. 4th ed. Thousand Oaks: Sage].
Findings: Harry's TP and the factors that facilitated and limited his practice were uncovered within five main themes: (a) creating communities of learners through restorative practice principles, (b) building on what students bring to school with them for a democratic curriculum, (c) teaching skills, bridging gaps, and the affective component, (d), working with communities in-between social justice illiteracy, and (e) utilizing diverse forms of assessment.
Conclusion: We confirmed that there is no best way to teach social justice through PE and that TP must be individual to the teacher. In addition, this study highlighted methods and pedagogies by which teachers could engage in TP. Finally, the study's findings implied how teacher educators might go about working with both preservice and inservice PE teachers with the goal that they focus on facilitating social justice through their pedagogical approach. 相似文献
