ABSTRACT

Background: Schoolchildren’s personality development is considered a central goal of physical education (PE). With regard to the relationship between psychological well-being and global self-esteem over the life course, the promotion of positive self-esteem is an issue of particular significance. Past research revealed that PE taught with an individualized teacher frame of reference (iTFR) and a reflexive teaching style is associated with positive effects on facets of children’s perceived sports competence. However, it remains an open question whether this teaching styles has the potential to promote positive self-esteem.

Purpose: The present study investigated whether a five-month teacher training, aimed to enhance the teachers’ iTFR and their reflexive teaching style in PE, has a positive effect on students’ perceived sports competence and their global self-esteem. To analyse the implementation quality, changes in students’ perceived iTFR and perceived reflexive teaching style were investigated.

Method: A total of 21 teachers were assigned to either an intervention group (n?=?13), receiving the five-month teacher training, or a control group (n?=?8) consisting of regular teaching without teacher training. The teacher training encompassed five three-hour consecutive sessions during which the teachers acquired theoretical and practical knowledge about the promotion of competence perceptions in PE with a reflexive teaching style and an iTFR. Between the sessions, the teachers were instructed to implement an iTFR and a reflexive teaching style into their own PE classes. To evaluate the effects of the teacher training, their students’ (N?=?315, 53.7% girls, M_age?=?13.2 y, SD_age?=?1.3 y) perceived teaching style (iTFR and reflexive teaching), perceived sports competence and global self-esteem were measured with paper-pencil questionnaires at three measurement points (pre, post and follow-up).

Findings: Linear mixed effect models showed that students of the intervention group reported an increase in their teachers’ reflexive teaching style, but there were no changes with regard to iTFR. With regard to students’ perceived sports competence and global self-esteem, there were significant interaction effects between time and group over a period of eight months (from pre-test to follow-up), indicating positive effects on these self-concept dimensions due to the teacher training.

Conclusion: The present study indicates that a long-term teacher training supports PE teachers to implement teaching styles with the aim to promote students’ self-concept. Furthermore, the findings lead to the assumption that a more pronounced iTFR in combination with an enhanced reflexive teaching style has the potential to positively influence schoolchildren’s perceived sports competence and global self-esteem.  相似文献   

Application of network meta-analysis in the field of physical activity and health promotion

Continued advancement in the field of physical activity and health promotion relies heavily on the synthesis of rigorous scientific evidence. As such, systematic reviews and meta-analyses of randomized controlled trials have led to a better understanding of which intervention strategies are superior (i.e., produce the greatest effects) in physical activity-based health behavior change interventions. Indeed, standard meta-analytic approaches have allowed researchers in the field to synthesize relevant experimental evidence using pairwise procedures that produce reliable estimates of the homogeneity, magnitude, and potential biases in the observed effects. However, pairwise meta-analytic procedures are only capable to discerning differences in effects between a select intervention strategy and a select comparison or control condition. In order to maximize the impact of physical activity interventions on health-related outcomes, it is necessary to establish evidence concerning the comparative efficacy of all relevant physical activity intervention strategies. The development of network meta-analysis (NMA)—most commonly used in medical-based clinical trials—has allowed for the quantification of indirect comparisons, even in the absence of direct, head-to-head trials. Thus, it stands to reason that NMA can be applied in physical activity and health promotion research to identify the best intervention strategies. Given that this analysis technique is novel and largely unexplored in the field of physical activity and health promotion, care must be taken in its application to ensure reliable estimates and discernment of the effect sizes among interventions. Therefore, the purpose of this review is to comment on the potential application and importance of NMA in the field of physical activity and health promotion, describe how to properly and effectively apply this technique, and suggest important considerations for its appropriate application in this field. In this paper, overviews of the foundations of NMA and commonly used approaches for conducting NMA are provided, followed by assumptions related to NMA, opportunities and challenges in NMA, and a step-by-step example of developing and conducting an NMA.  相似文献

足球比赛的负荷量化-结构、方法和特征     

缪律  史国生  黎涌明 《成都体育学院学报》2020,(2):93-99,106

足球比赛负荷是球员在比赛情景下完成各类动作所承受的物理、生理和心理等方面刺激之和。比赛负荷的量化结构分为外部和内部负荷,外部负荷的量化方法包括人工视频分析技术、自动轨迹追踪技术和全球定位设备,通过球员体能或技术表现的负荷量和强度来评定足球比赛中的行为活动特点,外部负荷特征表现为间歇性运动下频繁变向和短距离变速跑,高比例的中低强度无球跑穿插较少的高强度带球跑。内部负荷的量化方法包括耗氧量、心率和血乳酸等指标的测定,通过上述指标的变化幅度来评定足球比赛中的能量代谢水平;内部负荷特征表现为有氧供能为主、无氧磷酸原和糖酵解供能交替进行。现有研究局限为外部负荷低估了变向运动对足球比赛负荷的影响,内部负荷无法概括正式比赛的供能特征等。未来可尝试在优化量化方法基础上结合内外负荷,从而更精准地量化比赛负荷。  相似文献

运用双框架模型对中美竞技体育国际竞争力进行比较研究。认为:①从显现性框架分析,美国竞技体育国际竞争力一直稳定处于高位,而中国则呈现以2008年为峰顶的倒“U”型发展特征,且与美国还存在一定差距;②从解释性框架分析,美国竞技体育国际竞争力已趋于顶峰,而中国稳步提升;③中国竞技体育发展潜力巨大,但短时间内难以赶超美国;④“举国体制”有利于中国竞技体育显现性竞争力的提升,但与美国社会办竞技体育的发展模式相比,市场、社会在竞技体育发展中的作用发挥不足,不利于高经济性项目、高欣赏性项目的发展;⑤坚持“举国体制”、承办2022年冬奥会有利于中国竞技体育显现性竞争力的提升和冬季项目的发展,但同样存在竞技体育项目布局转型的困难和群众体育基础薄弱的困境。  相似文献   

优秀双向飞碟运动员3号 靶位击发节奏与脱靶关系研究     

耿正洋 《河北体育学院学报》2020,34(4):71-75

双向飞碟射击项目中3号靶位是8个靶位中射击命中难度最大的靶位，是制约运动员整体命中率的关键所在。将双向飞碟双靶分为1靶击发、随靶、2靶击发3个阶段，对3名国内优秀运动员击发节奏特征进行分析。发现：①1靶击发阶段的节奏直接影响2靶中靶情况，1靶击发用时越长，2靶质量越差，想要提高2靶的命中率必须要提高1靶的动作质量。②随靶阶段的人枪结合能力会影响2靶命中率。③优秀运动员2靶击发阶段的时间节奏一致性较强，动作自动化程度较高。④整体击发节奏慢更易造成2靶脱靶。提出，运动员要提高打好1靶的能力，在保证1靶质量的前提下加强快打技术训练，同时提高随靶阶段人枪结合能力，加强对技术的监控和分析，辅助运动训练，科学提高成绩。  相似文献
