现代竞技体育体能训练对改善女大学生脊柱功能的研究

脊柱功能是衡量人体健康水平的重要指标,对人体保持高质量的学习、生活和工作状态产生直接的影响。如何运用有效的训练改善和提高人体脊柱功能,应引起高度的重视。以黑龙江省30名女大学生为研究对象,制定有针对性的训练方案,进行为期3个月的运动干预实验,分5个阶段进行训练监控及训练效果评估。结果显示：全体受试对象脊柱直背趋势最为显著,脊柱姿势、柔韧性、稳定性整体较差,脊柱疾病风险较高;通过动态拉伸、颈肩及腰等功能性训练对改善女大学生脊柱功能效果显著;实施训练方案后,在第30天改善效果最为明显。     

基于互联网的运动干预项目对大学生体质健康影响的实验研究

运用文献资料、教学实验、数理统计等方法,揭示微信平台和移动健身运用(APP)对大学生体质健康水平的影响及其作用机制。结果:1)实验组实验后体质健康各项指标(身高体重除外)均有显著的提升(P<0.05),对照组各指标也均有上升趋势,但无统计学意义(P>0.05);2)实验组实验后各项指标(身高体重除外)显著高于对照组(P<0.05)。结论:1)基于互联网的线上运动干预项目可以有效促进大学生的体质健康水平,可以作为大学生体育锻炼习惯养成及体质健康促进的有效手段;2)线上运动干预项目促进大学生体质健康的作用机制是通过目标设定,自我监测行为,个性化定制与指导,社会互动等强化因素作用的结果。     

登山户外运动事故的原因分析与对策研究——基于中国登山协会2010-2015年度报告

通过文献资料法,数理统计法对2010-2015年登山户外运动事故进行分析,得出事故发生与参与时间,参与项目和组织形式的关系,并提出相应的对策。可以从国家,服务机构和个人三方面进行控制。国家应该发挥主体的作用,完善相关法律法规,强化相关机构;民间服务机构,一方面要有相关的资质和严谨的服务机构,另一方面,在员工的选拔和任用上也要严格把关;在个人方面,既要学习相关理论知识,还要熟悉各种实践操作,在活动前,活动中,活动后都要时刻注意风险,做好总结。

Low-intensity electrical muscle stimulation induces significant increases in muscle strength and cardiorespiratory fitness

The aim of this study was to investigate the effect of low-intensity exercise training using belt electrode skeletal muscle electrical stimulation on muscle strength and cardiorespiratory fitness in healthy subjects. Nineteen healthy subjects were allocated into control or intervention groups; in both groups the participants kept regular physical activity while the intervention group underwent 30 min B-SES training at 3–4 METs for four weeks. Knee extensor muscle strength and cardiorespiratory endurance during incremental exercise test were measured at baseline and after four weeks for all participants. The relative change of knee extensor muscle strength in the intervention group was significantly higher than control group (p?p?相似文献   

江西省赣州市农民体育健身工程现状调查与分析

采用问卷调查法、实地观察法、访谈法等,就农民体育健身工程对赣州市4个县40个行政村的村民进行了调查.结果表明:赣州市100个示范村的工程建设顺利完成,工程选址较合理,无产权纠纷,使用率较高,对社会、生活、环境产生了积极效益.工程管理不够规范、责权不够明确、融资渠道单一、农民的健身意识较差、社会体育指导员缺乏等是工程建设存在的主要问题.同时提出:强化政府职能,加大资金投入;加强体育骨干培训与管理,积极开展农村体育活动;建立完善的农民体育健身工程服务体系等建议,为赣州市乃至江西省农民体育健身工程的可持续发展提供理论依据.     

Comparative studies on phenotypic plasticity of two herbs, Changium smyrnioides and Anthriscus sylvestris

The endangered medicinal herb, Changium smyrnioides can only be found in deciduous forest gaps within the middle to northern subtropical broad-leaved evergreen forest zone of China. The considerable plasticity of its shoot and root structure helps it to capture light more effectively in winter and early spring, and to adapt to the soil moisture conditions in its narrow habitat. Another medicinal plant, Anthriscus sylvestris, is of similar economic importance but commonly distributed widely. In contrast to C. smyrnioides, it has low structural plasticity. It is also specialized to adapt to the moist and sunny environment, where habitat, such as the banks of creeks and rivers, is abundant.     

Learning about the past: exploring the opportunities and challenges of using an outdoor learning approach

This paper examines the potential of outdoor learning for supporting children’s understanding of and attitude towards history. A class of primary school children participated in an intensive experiential, residential history programme. A range of data was collected before, during and after the residential programme, and the findings suggest that the experience had a positive impact on the children’s attitude towards history and enabled many of the children to be able to easily recall highly specific factual knowledge. However, the children’s understanding of history as a provisional construct was not developed, as it was not a strong feature of the programme. Nor was the experiential nature of the experience fully exploited. Overall the study suggests that such a programme has the potential to support children’s learning of the past, but a deeper understanding of history, drawing on the benefits of outdoor learning pedagogy, needs to be planned for more explicitly.
