浅析青少年生理发育特点与体育教学卫生

合理的运动可以起到增强心脏功能，改善呼吸系统功能，提高消化系统功能。不合理的运动将会与之背道而驰。针对青少年身体各器官的生理发育特点，通过对运动系统、心血管系统和呼吸系统、神经系统的生理发育特点以及体育教学卫生等方面的分析研究，认为：在体育教学中，应根据青少年运动系统的卫生，注意青少年心血管系统和呼吸系统的卫生，还应把握青少年神经系统的发育特点，促进大脑皮层兴奋与抑制，均衡发展卫生。

体育专业大学生的从众心理研究

从体育学习、体育消费、考试以及课余生活方面对忻州师范学院体育专业大学生进行从众心理的调查,结果表明体育专业大学生在这几方面均有着普遍的从众现象。对体育专业大学生的心理特征进行分析研究,提出克服他们心理障碍的切实可行的方案,既要发挥从众心理在大学生中的积极作用,同时又要抑制它对当代大学生的负面影响,实现引导大学生拥有健康心理机制的目标。     

Understanding young Chinese Australian's (dis)engagement in Health and Physical Education and school sport

Background: School Health and Physical Education (HPE) and sport has increasingly become a complex cultural contact zone. With global population shifts, schools need policies and strategies to attend to the interests and needs of diverse student populations. School HPE and sport is a particularly significant site as it is a touchpoint for a range of cultural values and practices related to physical activity, the body, health and lifestyle proprieties.

Purpose: While there is a high Chinese student population in Australian schools, little research has been undertaken to understand their needs, experiences and perceptions in schools HPE and sport. In addition, research in the physical activity field is accentuated by paradigms that assume and perpetuate the binary notion of cultural beliefs and practices such as ‘West’ versus ‘East’ and in association with ‘Normal’ versus ‘Problematic’ lifestyles in relation to physical activity. We argue that, without conceding the epistemological understanding of ‘difference’, policies and practices that promote diversity can remain socially unjust and superficial.

Research design: This paper focuses on two schools in Queensland. The data collection process was underpinned by critical and interpretive ethnographic methods. The participants in Sage College consisted of seven girls of whom three were in Year 8, three in Year 9 and one in Year 10. At Routledge State High, a state-owned, secular and coeducational secondary school, the cohort consisted of two girls in Year 8, one girl and two boys from Year 9.

Results: This paper draws on Bourdieu's concepts of habitus, capital, field and doxa and the Chinese Confucianism philosophy of ‘Complementary difference’ to understand the various perceptions and experiences of young Chinese Australians in schools HPE and sport. Results invite us to seek an understanding of students’ subjectivities and disrupt the binary differences in cultural values and attributes to promote multicultural education.

Conclusion and recommendation: Moving beyond the Australia's Anglo-Celtic centred HPE and the limitations of a Western view of exclusive opposites, this paper makes an original contribution to knowledge by presenting a ‘heuristic of difference’ model that accommodates Western and Chinese perspectives in Australian HPE research.

Accelerometer data requirements for reliable estimation of habitual physical activity and sedentary time of children during the early years - a worked example following a stepped approach

This study presents a worked example of a stepped process to reliably estimate the habitual physical activity and sedentary time of a sample of young children. A total of 299 children (2.9 ± 0.6 years) were recruited. Outcome variables were daily minutes of total physical activity, sedentary time, moderate to vigorous physical activity and proportional values of each variable. In total, 282 (94%) provided 3 h of accelerometer data on ≥1 day and were included in a 6-step process: Step-1: determine minimum wear-time; Step-2: process 7-day-data; Step-3: determine the inclusion of a weekend day; Step-4: examine day-to-day variability; Step-5: calculate single day intraclass correlation (ICC) (2,1); Step-6: calculate number of days required to reach reliability. Following the process the results were, Step-1: 6 h was estimated as minimum wear-time of a standard day. Step-2: 98 (32%) children had ≥6 h wear on 7 days. Step-3: no differences were found between weekdays and weekend days (P ≥ 0.05). Step-4: no differences were found between day-to-day variability (P ≥ 0.05). Step-5: single day ICC’s (2,1) ranged from 0.48 (total physical activity and sedentary time) to 0.53 (proportion of moderate to vigorous physical activity). Step-6: to reach reliability (ICC = 0.7), 3 days were required for all outcomes. In conclusion following a 7 day wear protocol, ≥6 h on any 3 days was found to have acceptable reliability. The stepped-process offers researchers a method to derive sample-specific wear-time criterion.     

中国皮划艇国家二队功能动作筛查的应用研究

运用文献资料法、测试法、问卷调查法、专家访谈法和数理统计法对国家皮划艇青年队进行功能动作筛查测试,根据测试结果为备战2020年奥运会提供数据及理论的支持。通过研究发现:划艇运动员的总分情况整体优于皮艇运动员;大部分运动员髋、膝、踝三关节在单一的运动平面中具有较好的协调和稳定性,但在两个以上的运动平面中完成动作的稳定和控制能力有待提高;运动员的髋关节、肩关节及股四头肌柔韧性存在不平衡现象,左侧链与右侧链在多运动平面中协调稳定性也存在不平衡现象;运动员的损伤率较高,且损伤的主要部位是肩和腰。
