父母教养方式对大学生子女体重指数和身体活动行为的影响研究

运用问卷调查法和数理统计法,对176名大学生及其父母的饮食、身体活动及教养方式进行调查分析。结果显示,子女同父母在体重指数（BMI）上具有显著正相关关系（r=19,P＜05）,而在每周平均身体活动量上无显著相关（r=08,P=17）。回归分析表明,三类教养方式对子女BMI均无直接预测作用,然而专制型父母教养方式对父母与子女BMI的相关关系起间接调节作用（P＜01）;在子女身体活动行为方面,溺爱型父母教养方式更有可能导致子女的身体活动不足（P＜01）。研究结果表明,大学生离开家庭环境后,父母教养方式仍然对子女BMI和身体活动行为产生持续影响,父母与子女BMI方面存在相关关系。为今后在青少年肥胖干预及身体活动促进研究中纳入教养方式因素提供了实证依据。     

Extended Validation of the Korean Version of the Quality of Life Survey

In this study, we examined the factor structure and reliability of the Korean Quality of Life (KQoL) survey and compared the KQoL survey to both the World Health Organization Quality of Life-Brief Version (WHOQOL-BREF) and the Satisfaction with Life Scale (SWLS). We also assessed associations between KQoL scores and physical activity (PA) participation. Participants were 557 (male = 281, female = 276) healthy Korean adults with ages between 18 and 71 years (M = 33.2, SD = 14.2). Results of confirmatory factor analyses confirmed the 7-subscale model and indicated acceptable values supporting convergent validity (χ² = 1,678.758, df = 443, p < .001, RMSR = .045, RMSEA = .071, TLI = .880, CFI = .892). Correlations of KQoL subscales with similar subscales of WHOQOL-BREF and with SWLS supported concurrent validity. Results confirm that the KQoL survey can assess multidimensional aspects of quality of life (QoL), including spiritual, physical, social, and psychological. KQoL scores were positively related to PA participation, in line with previous research supporting the positive association of PA with QoL.     

Framing citizenship: from assumptions to possibilities in health and physical education

Within the Australian context physical education (PE) and more recently health and physical education (HPE) have long been ascribed utilitarian value for producing healthy citizens. Whilst this has not been a linear progression over time, traces from the past do inform current assumptions about this utilitarian role. Of consequence are historical contingencies and responses to societal problems around health-related conduct and capabilities of the nations’ citizens. In this paper a genealogical approach is adopted to explore discourses and power relations that have framed the contribution of PE and HPE in shaping students for healthy citizenship. Disciplinary technologies associated with military-style physical training, civilising technologies of game play and responsibilising governmental technologies of contemporary policies will be explored. I conclude in arguing that if HPE is to prepare all students for equitable, inclusive citizenship what is required is the adoption of curricula and pedagogies that counteract hegemonic notions of individual responsibility for healthy citizenship.     

Can sit-to-stand muscle power explain the ability to perform functional tasks in adults with severe obesity?

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m²) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.     

Effects of Different Chair-Based Exercises on Salivary Biomarkers and Functional Autonomy in Institutionalized Older Women

Purpose: The aim of this study was to test the effects of chair-based exercise programs on salivary stress hormones, physical fitness, and functional autonomy of institutionalized older women. Method: In total, 47 participants (80 ± 8.04 years old) were recruited and allocated into three groups: chair-based aerobic exercises (CAE, n = 19), chair-based elastic-band strength exercises (CSE, n = 15), and a control group (CG, n = 13). A 14-week exercise intervention was done for the CAE and CSE groups, two times per week, in no consecutive days. Members of the CG did not participate in any type of exercise but kept their regular lifestyle. Fear of falling, autonomy, physical fitness, salivary cortisol, and alpha-amylase levels were assessed before and after the intervention. Results: The CAE group improved upper and lower body strength, agility–dynamic balance, and autonomy, with fear of falling decreasing significantly (p < .05, moderate effect size). Both exercise groups showed a trend toward an increase in salivary alpha-amylase levels (CAE = 43%, d = .31, and CSE = 44%, d = .41). Conclusion: Both exercise programs were able to improve functional autonomy, even in elders older than 80 years of age. It might be interesting to investigate the effectiveness of combining both aerobic and strength exercises in a unique protocol. The modulation effect of exercise in the hormonal responses needs to be further explored.     

Facilitators and Barriers to Movement Integration in Elementary Classrooms: A Systematic Review

Purpose: A systematic review was conducted to identify facilitators and barriers to movement integration (MI) in elementary school classrooms. Method: Online databases (Educational Resources Information Center, Google Scholar, PsycINFO, and PubMed) served as data sources for the study. Following the PRISMA guidelines, relevant published research on MI was identified and screened for inclusion in a qualitative synthesis. Content analysis of the included articles (N = 28) was used to identify themes of MI facilitators and barriers. Facilitators and barriers were then categorized using a social-ecological framework. Results: A total of 12 themes of MI facilitators and barriers were identified and categorized into two social-ecological levels: institutional factors (e.g., administrative support, resources) and intrapersonal factors (e.g., teacher confidence, ease of implementation). Conclusion: This review can inform research and practice aimed at supporting the implementation of MI in elementary classrooms.     

学生体质健康测试第三方机构督查的独立性

运用文献资料法、专家访谈法等研究方法,对我国各省份学生体质健康测试第三方机构督查的独立性进行研究。通过对我国各省份学生体质健康测试第三方机构督查独立性的现状、问题、原因及对策的探索,在政策上,可以为教育行政部门改革提供决策思路和参考,在实践上,可以提高学生体质健康测试督查的权威性和有效性,倒逼学生体质健康测试的规范化实施。研究发现,当前我国各省份学生体质健康测试第三方机构督查的独立性差,主要体现在第三方机构与教育厅存在行政隶属关系、存在利益关联、第三方机构工作自主性差3个方面。影响学生体质健康测试第三方机构督查独立性的因素主要为中国传统文化对体育和公民意识的漠视、当事方的利益诉求对第三方机构督查独立性的限制、法规制度缺位、第三方机构发育程度低等。提出保障学生体质健康测试第三方机构督查独立性的对策：教育部对第三方机构督查的责权划分做出设计安排,培养公民意识,扩宽经费来源渠道,第三方机构完善自身治理。

身体活动对改善药物成瘾戒断者脑功能损伤的研究——来自抑制加工及脑功能静息态的证据

目的：探讨身体活动对药物成瘾戒断者抑制能力及静息态脑功能的改善,拟为药物成瘾提供有效的辅助治疗手段。方法：将药物成瘾戒断者按身体活动量分为活动组和久坐组,首先进行Go/NoGo抑制能力测试,然后采集他们的静息态功能磁共振数据。选取静息态的两项重要分析方法——低频振幅（amplitude of low frequency fluctuations,ALFF）和局部一致性（regional homogeneity,ReHo）来探讨身体活动对药物成瘾戒断者脑功能损伤的改善。结果：①Go/NoGo测试：活动组NoGo正确率显著高于久坐组。②ALFF分析：活动组在双侧脑岛、左侧额下回眶部、双侧额内侧回、左侧前扣带回、右侧背外侧前额叶、左侧枕上回、左侧辅助运动区、双侧内侧扣带回ALFF显著高于久坐组。③ReHo分析：活动组在左侧枕中回、双侧背外侧前额叶、左侧辅助运动区ReHo显著高于久坐组。这些显著差异脑区主要与成瘾的抑制能力有关。结论：①身体活动能有效地提高药物成瘾戒断者的抑制能力。②身体活动是修复药物成瘾戒断者大脑功能损伤的关键因素之一。身体活动可通过增加药物成瘾戒断者静息状态下脑功能的低频振幅和局部一致性,改善药物成瘾戒断者大脑功能损伤。
