The purpose of this study was to differences in cardiovascular risk factors and upper and lower limb muscle function according to the WHR classification in women with obese. Eighty-three obese women with over 30% body fat who aged between 20- and 30-years were divided into 3 groups: normal control group (NCG, n=6), obese women with low WHR group (WHR 0.85 or less+ more than 30% body fat, OLW, n=64), obese women with high WHR group (WHR 0.85 or more+ more than 30% body fat, OHW, n=13). We performed measurements to determine cardiovascular risk factors, basic physical fitness, isokinetic knee and trunk muscle functions according to WHR classification.As the result of this study, the knee flexor peak torque and hamstring to quadriceps torque ratio (H:Q ratio) as well as isokinetic endurance capacity of the right and left knee flexors were significantly higher in the NCG compared to the OLW and OHW. In addition, sergeant jump was significantly higher in the NCG compared to the OLW and OHW. But other basic physical fitness factors and cardiovascular disease risk factors were no significant difference between all groups. Our findings confirmed that WHR risk level may be an important predictor of lower extremity muscle function in obese women.
本研究的目的是根据WHR分级探讨肥胖女性心血管危险因素及上肢和下肢肌肉功能的差异。将83名20 ~ 30岁体脂大于30%的肥胖女性分为3组:正常对照组(NCG, n=6)、低腰宽比肥胖组(腰宽比0.85及以下+ 30%以上体脂,OLW, n=64)、高腰宽比肥胖组(腰宽比0.85及以上+ 30%以上体脂,OHW, n=13)。我们通过测量来确定心血管危险因素、基本体能、等速膝关节和躯干肌肉功能。本研究的结果是,NCG组的膝屈肌峰值扭矩、腘绳肌与股四头肌扭矩比(H:Q ratio)以及左右膝屈肌的等速耐力能力明显高于OLW和OHW组。此外,NCG的中士跳跃率明显高于OHW和OLW。而其他基本体质因素和心血管疾病危险因素在各组间无显著差异。我们的研究结果证实,腰臀重风险水平可能是肥胖女性下肢肌肉功能的重要预测指标。

The aim of this study was to analyze the breast cancer survivors' difficulties in participating in sports as cancer aftercare. This study employed the case study and purposive sampling to obtain the sample from five breast cancer survivors, two surgical oncologists, and a cancer aftercare NGO specialist. This study conducted the participatory observation method and depth interviews to categorize and conceptualize based on transcribed data with selected study participants. The study was to identify the essential themes, and four medical experts addressed within and across cases. Three essential themes were revealed: financial difficulty, severe chronic condition, and social role. Firstly, breast cancer survivors suffer financial difficulty after a cancer diagnosis because of their career breaks or the absence of economic activities. This situation put survivors hard to take part in sports with high expenses or customized personal programs. Secondly, breast cancer survivors suffer experience motor disorders due to low motivation due to poor physical ability. Therefore, follow-up measures for them should be taken at the welfare level. Thirdly, breast cancer survivors continue to shoulder a disproportionate share burden of Balancing work and family obligations. Cancer survivors who are parents or family caregivers have taken on even more during the cancer treatment. They were already shouldering the majority of financial, social, and family care responsibilities. That is wholly inadequate for most cancer survivors to find enough time to work out or do sports regularly but sporadic or never for themselves and their health.
本研究的目的是分析乳癌幸存者参与运动作为癌症后护的困难。本研究采用个案研究法和目的抽样法,从5名乳腺癌幸存者、2名外科肿瘤学家和1名癌症善后非政府组织专家中获取样本。本研究采用参与式观察法和深度访谈,根据转录的数据对选定的研究参与者进行分类和概念化。该研究旨在确定基本主题,并由四位医学专家在病例内部和跨病例进行讨论。研究揭示了三个基本主题:经济困难、严重慢性疾病和社会角色。首先,乳腺癌幸存者在诊断出癌症后,由于职业中断或缺乏经济活动而遭受经济困难。这种情况使幸存者很难参加高费用或定制个人项目的体育活动。其次,乳腺癌幸存者由于身体能力差而缺乏动力,因此会出现运动障碍。因此,应该在福利层面对他们采取后续措施。第三,乳腺癌幸存者在平衡工作和家庭义务方面继续承担着不成比例的负担。作为父母或家庭照顾者的癌症幸存者在癌症治疗期间承担了更多的负担。她们已经承担了大部分的经济、社会和家庭照顾责任。对于大多数癌症幸存者来说,这是完全不够的,他们没有足够的时间定期锻炼或做运动,而是偶尔或从不为自己和他们的健康着想。

Human movement and motor behavior science involve various theoretical frameworks and methodologies. This study describes the force control of motor phenomenon, processes of linear or nonlinear dynamics, and proposes a system approach as an additional potential aspect. Thus far, issues regarding these motor control and learning paradigms were critically examined, and their respective mechanisms were compared using descriptive analysis. Elaborate simulations based on the transitions and development flow of each component at issue contributed to the linear approach, laid concrete emphasis on the advantages of the nonlinear approach, and empirically derived the rationale for the indispensable application of system dynamics. Sports science can benefit from system dynamics associated with human motor behavior, as demonstrated in this study.
人体运动和运动行为科学涉及多种理论框架和方法。本研究描述了电机现象、线性或非线性动力学过程的力控制,并提出了一种系统方法作为附加的潜在方面。到目前为止,对这些运动控制和学习范式的问题进行了严格的研究,并使用描述性分析对其各自的机制进行了比较。基于所讨论的每个组件的转换和开发流程的详细模拟有助于线性方法,具体强调非线性方法的优点,并经验地推导出系统动力学不可或缺的应用的基本原理。正如这项研究所证明的那样,运动科学可以从与人类运动行为相关的系统动力学中受益。

This study aimed to describe and compare the pacing strategy and performance of world level under 19 (U19), under 23(U23) and senior single scullers during world championship races. Data are from 8 years of Rowing World Championships A and B finals of single scull races for U19, U23 and senior age scullers. Pacing was determined for velocity, stroke rate and, distance per stroke (SD). Scullers presented a fast start strategy for all races investigated. There was no significant difference in pacing between age groups. Velocity peaked at the 100m (U19) and 150m (U23 and senior) mark. The scullers in the older age groups showed superior performance scores of the studied variables. U19, Under 23 and senior single scullers present similar pacing regardless of their age group. Performance of single sculler improve from U19, to U23 to senior for both lightweight and heavyweight classes. The results of this study may serve as a reference for athletes, coaches, and sports scientists to be implemented in training.

A physically educated person is characterized as an individual who has the motivation, competence, understanding, and knowledge to enjoy physical activity in a healthy way. Given that physical literacy (PL) development is a lifelong process, the recording of the process, called charting, has critical importance in PL development. This study aimed to explore features of student participation in an e-portfolio for charting PL and its impacts on student learning. Participants were 10 middle school students selected on the basis of gender, technological competence, and interest in physical education. Participants took part in PL charting programs for 10 weeks by utilizing an e-portfolio developed by the researcher. Data were collected from semi-structured interviews with participants and student work samples retrieved from the e-portfolio. The features of students’ PL charting in the e-portfolio were categorized as (a) digital fumblers, (b) superficial participants, (c) passionate creators, and (d) journey reflectors, depending upon the levels of technological competence and motivation for PL recording activities. Participation in PL charting through an e-portfolio (a) enhanced sense of achievement and motivation for future PL growth in students, (b) enabled students to obtain tailored strategic support from the teacher, and (c) helped them perceive learning as continual growth. The findings of this study suggest an e-portfolio can be a viable tool for PL charting by providing opportunities to keep track of students’ learning process and reflect on their PL-related learning activities.
受过体育教育的人的特点是具有以健康的方式享受体育活动的动机、能力、理解和知识的个人。鉴于物理素养(PL)的发展是一个终身的过程,记录这一过程,称为图表,在PL发展中具有至关重要的意义。本研究旨在探讨学生参与电子档案袋的特征及其对学生学习的影响。研究对象为根据性别、技术能力和体育兴趣选择的10名中学生。参与者利用研究人员开发的电子文件夹参加了为期10周的PL制图计划。数据收集自对参与者的半结构化访谈和从电子档案中检索的学生工作样本。根据技术能力水平和PL记录活动的动机,学生在电子作品集中的PL图表特征被归类为(a)数字摸索者,(b)肤浅参与者,(c)热情创造者和(d)旅程反射者。通过电子档案袋参与学习学习图表(a)增强了学生的成就感和对未来学习学习的动力,(b)使学生能够从老师那里获得量身定制的战略支持,(c)帮助他们将学习视为持续成长。本研究的结果表明,通过提供跟踪学生学习过程和反思他们与PL相关的学习活动的机会,电子档案可以成为PL图表的可行工具。

Seoi-nage is a representative technique frequently used in judo. Therefore, it is essential to identify how seoi-nage force characteristics change under various conditions. This study aimed to determine the differences in the force characteristics at different performance heights of elite male judo athletes. Twenty elite male judo athletes participated in the study. They were asked to perform seoi-nage at different heights (80 cm and 60 cm) using a rubber band as a practice situation. Data were collected by a force-measurement device with a rubber band connected to the device. The time variables, force value magnitude, force value rate, and force value angle in the vertical/horizontal planes were calculated and compared at 80 cm and 60 cm. There were significant differences in the force magnitude and the force vector vertical angle at 80 cm and 60 cm (p<.05). The force magnitude was greater at 60 cm than at 80 cm height. The force vector vertical angle was greater at 60 cm than at 80 cm height. In conclusion, seoi-nage at 80 cm height requires less force than at 60 cm; hence, judo players should perform the seoi-nage throw placing their center of mass lower than that of an opponent. Practicing seoi-nage repeatedly at 60 cm height under the training conditions is recommended. Seoi-nage at 60 cm height can be considered an effective training method for increasing the ability to handle difficult opponents.
seoage是柔道中常用的代表性技术。因此,有必要确定在不同条件下的海上力特性是如何变化的。本研究旨在探讨优秀男子柔道运动员在不同表演高度时的力特性差异。20名优秀的男性柔道运动员参加了这项研究。他们被要求在不同的高度(80厘米和60厘米)使用橡皮筋作为练习情境。数据通过力测量装置收集,力测量装置上连接有橡皮筋。计算80 cm和60 cm垂直/水平平面上的时间变量、力值大小、力值速率和力值角。在80 cm和60 cm处的力大小和力矢量垂直角度差异有统计学意义(p< 0.05)。60 cm处的力大小大于80 cm处的力大小。力矢量垂直角度在60 cm处大于在80 cm处。综上所述,80 cm高度处的船体所需的力小于60 cm高度处;因此,柔道选手应该在投掷时将他们的重心放在比对手低的位置。建议在训练条件下,在60厘米的高度上反复练习。在60厘米的高度上进行“打球”,可以看作是提高对付难对付对手能力的有效训练方法。

The purpose of this study was to investigate the vertical stiffness and agonist-antagonist muscle co-activation according to running velocity. Eighteen runners asked to perform running on an instrumented treadmill (HP Cosmos, Germany) with a capacitance-based pressure platform at 40, 50, 60, 70, 80% of maximum velocities, 19 infrared cameras and surface electromyography were used to measure kinematics and muscle activation. Vertical stiffness increased significantly as running speed increased. On the other hand, co-activation decreased significantly as the running speed increased. We conclude that antagonist muscle groups decrease with increasing running speed and depend on agonist muscle group activity.
本研究的目的是探讨垂直刚度和激动-拮抗剂肌肉协同活化随跑步速度的变化。18名跑步者被要求在仪器跑步机上(HP Cosmos,德国)以最大速度的40,50,60,70,80%进行跑步,并使用19台红外摄像机和表面肌电图来测量运动学和肌肉激活。垂直刚度随着运行速度的增加而显著增加。另一方面,随着运行速度的增加,共激活显著降低。我们得出结论,拮抗剂肌群随着跑步速度的增加而减少,并取决于激动剂肌群的活性。

Common Cartesian dualisms (e.g., mind vs. body) are misleading in understanding human action likephysical activity. Therefore, in this paper, we will challenge the typical dualism habitus vs. reflexivityand showcase that exercise habitus and reflexivity are embodied encompassing familial, cultural,cognitive, emotional, and corporeal elements that inform exercise decisions. Exercise tradition is not lostin the modern globalized world; rather, it remains strong (e.g., instead of relying on screens, youngpeople enjoy being active outdoors). Exercise habitus and reflexivity need to be studied together withemotions, which are embodied and constitute an integral part of them. The embodied nature of exercisehabitus and reflexivity form human consciousness and can better explain physical activity choices thanCartesian dualisms, such as cognitive vs. bodily elements.
常见的笛卡儿二元论(例如,心灵与身体)在理解像身体活动这样的人类行为时是有误导性的。因此,在本文中,我们将挑战典型的二元论习惯与反身性,并展示运动习惯和反身性的体现,包括为运动决策提供信息的家庭、文化、认知、情感和物质因素。在全球化的现代世界,运动传统并没有消失;相反,它仍然很强大(例如,年轻人不依赖屏幕,而是喜欢在户外活动)。运动习惯和反身性需要与运动一起研究,运动是运动习惯和反身性的具体体现,是运动习惯和反身性的有机组成部分。运动习惯和反身性的具体性质形成了人类意识,比笛卡尔的二元论(如认知与身体因素)能更好地解释体育活动选择。

The purpose of this study is to establish a simpler way to assess cardiopulmonary function in handball athletes whose continuous aerobic ability is vital in games using field tests, as well as to provide basic data on changes in lactic acid concentration. A total of 8 youth elite male handball athletes participated in this study. Participants visited three times in total. The first was assigned to graded exercise test and body composition measurements. Participants were then randomly assigned to a 20-meter shuttle ride or Yo-Yo Intermediate Recovery. All participants measured the lactic acid concentration after each exercise test. There were no significant differences in the VO2max (ml/kg/min) results in each test. There was no significant difference immediately after exercise of each test, after 5 minutes, after 10 minutes, and after 20 minutes. Compared to the golden standard GXT, there is no difference in maximum oxygen intake and lactic acid concentration after the two field tests, so both tests are expected to be efficiently used to evaluate the aerobic ability and develop training programs in the field.
本研究的目的是建立一种更简单的方法来评估手球运动员的心肺功能,这些运动员的持续有氧能力在比赛中至关重要,并通过现场测试提供乳酸浓度变化的基础数据。共有8名青少年优秀男子手球运动员参与了本研究。参与者共访问了三次。第一组被分配进行分级运动测试和身体成分测量。然后,参与者被随机分配参加20米的穿梭运动或溜溜球中级恢复运动。所有参与者在每次运动测试后都测量了乳酸浓度。各试验VO2max (ml/kg/min)结果无显著差异。在运动后5分钟、10分钟和20分钟后,各测试的运动后立即、5分钟后、10分钟后和20分钟后无显著差异。与黄金标准GXT相比,两种野外试验的最大摄氧量和乳酸浓度没有差异,因此这两种试验有望有效地用于评价有氧能力和制定野外训练计划。

The purpose of this study was to examine the mediating effect of emotion regulation in the relationship between perfectionism and self-handicapping. After 503 college dancers (414 females, 89 males) completed the battery of questionnaires, the data were analyzed for descriptive statistics and analyzed by frequency analysis, correlation analysis. The bootstrapping method was used to verify the statistical significance of the indirect effect. The results showed that the reappraisal of emotion-regulation significantly mediated the relationship between self-oriented perfectionism and behavioral self-handicapping. Also determined that the suppression of emotion regulation significantly mediated the relationship between socially prescribed perfectionism and claimed self-handicapping. This study demonstrates that perfectionism and self-handicapping will have a different relationship depending on dancers’ types of emotion regulation. These findings provide valuable information on the psychological coping strategies used to control the negative emotion that are related to perfectionism among dancers.
摘要本研究旨在探讨情绪调节在完美主义与自我设限之间的中介作用。对503名高校舞蹈演员(女414人,男89人)完成问卷调查后,对数据进行描述性统计和频率分析、相关分析。采用自举法验证间接效应的统计显著性。结果表明,情绪调节的重评价在自我导向型完美主义与行为自我妨碍之间具有显著的中介作用。同时确定情绪调节的抑制在社会规定的完美主义和自我设限之间的关系中起着显著的中介作用。本研究表明,完美主义和自我设限会因舞者情绪调节类型的不同而产生不同的关系。这些发现为舞者控制与完美主义相关的负面情绪的心理应对策略提供了有价值的信息。
