大健康视野下老年功能性力量评估——以武汉市老年太极人群为例     

肖剑  邹克宁  李小兰 《武汉体育学院学报》2019,53(2):74-80

采用文献法、测试法、数理统计等方法，以武汉市十三个行政区内528名以太极拳为主要体育健身方式的老年人为样本，以马步蹲起、弓箭步蹲起、肘撑侧桥、肘撑侧桥举腿等与日常生活活动相关联的四个基础动作为测试内容。研究表明，受试人群普遍存在下肢与躯干的功能性力量不足、左右侧肌肉链力量不均衡的问题。虽然样本人群经常进行以太极拳为主要形式的体育锻炼，但在锻炼过程中侧重于套路技能的演练，对功能性力量训练的认识不足及缺乏相应的训练方法，存在科学性盲区，需要引起重视。  相似文献

Guiding Low Spatial Ability Individuals through Visual Cueing: The Dual Importance of Where and When to Look     

Victoria A. Roach  Graham M. Fraser  James H. Kryklywy  Derek G.V. Mitchell  Timothy D. Wilson 《Anatomical sciences education》2019,12(1):32-42

Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P < 0.001); however, an interaction was observed between treatment and test iteration (P = 0.024). The effect of guidance on scores was contingent on when the guidance was applied. When guidance was applied early, scores were significantly greater than expected (P = 0.028). These findings suggest that by guiding individuals with low mental rotation ability “where” to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

The application of inertial measurement units and functional principal component analysis to evaluate movement in the forward 3½ pike somersault springboard dive     

Cherie Walker  John Warmenhoven  Peter J. Sinclair 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(2):146-162

Based on technological and analytical advances, the capability to more accurately and finitely examine biomechanical and skill characteristics of movement has improved. The purpose of this study was to use Inertial Measurement Units (IMUs) and Functional Principal Components Analysis (fPCA) to examine the role of movement variability (assessed via angular velocity), on 2 divers (1 international level; 1 national) performing the forward 3½ pike somersault dive. Analysis of angular velocity curves during ive-flight identified 5 fPCs, accounting for 96.5% of movement variability. The national diver’s scatter plots and standard deviation of fPC scores illustrated larger magnitudes of angular velocity variability across dive flight. For fPC1 and fPC3, magnitudes of SD variability were 282.6 and 201.5, respectively. The international diver illustrated more consistent angular velocity profiles, with clustering of fPCs scores (e.g., fPC1 & 3 = SD’s of 75.2 & 68.0). To account for lower variability in the international diver, the ability to better coordinate movement sequences and functionally utilise feedback in response to initiation of the somersault position is highlighted. Overall, findings highlight how both IMUs and fPCA can more holistically and finitely examine the biomechanical and skill characteristics of movement sequences with the capability to inform athlete development.  相似文献   

Blogadapting: Adaptation Experiences among Expatriate Bloggers     

Clark Callahan  Jesse King  Audrey Halversen 《Journal of Intercultural Communication Research》2020,49(3):227-241

ABSTRACT

Increased global communication is adjusting traditional models of cross-cultural communication. Specifically, changes in international communication processes have caused increased scrutiny of cross-culture adaptation theory. This is especially true when focusing on the difference between cultural adaptation and functional fitness. The purpose of this research is to address changes in global communications by testing to see if there is a difference between two important theoretical concepts within cross-cultural adaptation theory – linear and non-linear adaptation. Findings indicate that cultural sojourners do not equate cross-cultural adaptation with linear models of functional fitness. Models that equate the two should be revisited.  相似文献   

定向行走课程与教学专业能力研究     

杞昭安 《现代特殊教育》2020,(2):26-37

从感觉训练、概念发展、行动技能、定向系统、求助技能、安全议题、小区资源与大众运输系统七个方面选取50项能力指标,对海峡两岸64名担任定向行走课程的教师进行问卷调查。调查结果显示:大多数被调查者认可这50项能力指标;定向行走教师对自己的课程与教学专业能力认可度多为中等,需要进一步作培训。同时发现,在定向行走课程与专业能力各向度的重要程度上,海峡两岸定向行走教师的认知有显著差异,各向度胜任程度的差异更加明显;而定向行走教师的年龄对定向行走课程与教学专业能力在重要程度和胜任程度上并没有显著差异;海峡两岸担任定向行走课程的教师,多数认为有培训的必要。建议将重要性在3.5以上的题目编制为《定向行走专业能力检核表》;将定向行走专业能力胜任程度在3.5以下的向度作为定向行走师资培训的参考。  相似文献   

Does spatial awareness training affect anatomy learning in medical students?     

Rene A. Gonzales  Gordon Ferns  Marc A. T. M. Vorstenbosch  Claire F. Smith 《Anatomical sciences education》2020,13(6):707-720

Spatial ability (SA) is the cognitive capacity to understand and mentally manipulate concepts of objects, remembering relationships among their parts and those of their surroundings. Spatial ability provides a learning advantage in science and may be useful in anatomy and technical skills in health care. This study aimed to assess the relationship between SA and anatomy scores in first- and second-year medical students. The training sessions focused on the analysis of the spatial component of objects' structure and their interaction as applied to medicine; SA was tested using the Visualization of Rotation (ROT) test. The intervention group (n = 29) received training and their pre- and post-training scores for the SA tests were compared to a control group (n = 75). Both groups improved their mean scores in the follow-up SA test (P < 0.010). There was no significant difference in SA scores between the groups for either SA test (P = 0.31, P = 0.90). The SA scores for female students were significantly lower than for male students, both at baseline and follow-up (P < 0.010). Anatomy training and assessment were administered by the anatomy department of the medical school, and examination scores were not significantly different between the two groups post-intervention (P = 0.33). However, participants with scores in the bottom quartile for SA performed worse in the anatomy questions (P < 0.001). Spatial awareness training did not improve SA or anatomy scores; however, SA may identify students who may benefit from additional academic support.  相似文献
