大学生涉跑猝死事件的体医融合防卫机制研究     

洪邦辉  胡庆山  张恒波  向彪 《武汉体育学院学报》2020,54(2):32-36,58

近年来，大学生身体素质不佳，已成为"老大难"，也是刻不容缓需要解决的问题，多地曾出现在体测、运动会、马拉松中晕倒甚至猝死事件，这给学校体育工作的开展带来不小的考验。带着因涉跑引起猝死的疑问，通过猝死案例分析，探究高校大学生猝死的病理学的非运动成因。研究认为：涉跑猝死的主因是先天性生理疾病，运动不是引发猝死的主要诱因，并提出了预防运动猝死的"堵疏结合"的医学监控策略和体医融合防卫机制构建方法。建议通过入校时医学筛查、跑前医学检查、跑中医学观察、猝死现场急救、跑后跟踪复查降低猝死风险；建立宿舍、运动场地、运动项目的全覆盖的心脏复苏志愿队伍，实施"黄金8分钟"内的急救生存链；建立学生、学校、政府、社会四方体育运动分级分类保险制度，从风险转移和人道主义援助进行关怀；建立涉跑猝死、猝死、非正常死亡的数据库，开展非正常死亡人员的病理学研究；建立全生命周期医学监控和健康安全宣传教育，形成全方位、全过程、全人员的体医融合防卫机制。  相似文献   

Blockchain and sustainable supply chain management in developing countries     

《International Journal of Information Management》2021

Theoretical, empirical and anecdotal evidence suggests that there are more violations of sustainability principles in supply chains in developing countries than in developed countries. Recent research has demonstrated that blockchain can play an important role in promoting supply chain sustainability. In this paper we argue that blockchain’s characteristics are especially important for enforcing sustainability standards in developing countries. We analyze multiple case studies of blockchain projects implemented in supply chains in developing countries to assess product quality, environmental accounting and social impact measurement. We have developed seven propositions, which describe how blockchain can help address a number of challenges various stakeholders face in promoting sustainable supply chains in developing countries. The challenges that the propositions deal with include those associated with an unfavorable institutional environment, high costs, technological limitations, unequal power distribution among supply chain partners and porosity and opacity of value delivery networks.  相似文献

Kinematic analysis of the drag flick in field hockey     

Rony Ibrahim  Gert S. Faber  Jaap H. van Dieën 《Sports biomechanics / International Society of Biomechanics in Sports》2017,16(1):45-57

Attaining high speed of the stick head and consequently of the ball is essential for successful performance of the drag flick in field hockey, but the coordination pattern used to maximise stick head speed is unknown. The kinematics of the drag flick was studied in ten elite hockey players who performed twenty shots each towards a target located 1.5 m high. A 150 Hz active marker motion analysis system was used, alongside two force plates to detect foot touchdown. Angular velocity and contribution to stick endpoint speed of upper body joints were analysed. Repeated measures ANOVA was used to compare timing of onset and peak angular velocities between joints. Participants used a kinematic pattern that was close to a proximal-to-distal sequence. Trunk axial rotation and lateral rotation towards the target, right wrist flexion and left wrist extension were the main contributors to stick endpoint speed. Coaches should emphasise trunk rotations and wrist flexion and extension movements for maximising stick head speed. Given the high level of the participants in this study, the coordination of joints motions, as reported here, can serve as a guideline for drag flick training.  相似文献

Hip and upper extremity kinematics in youth baseball pitchers     

Taylor Holt 《Journal of sports sciences》2016,34(9):856-861

The purpose of this study was to examine the relationship between dynamic hip rotational range of motion and upper extremity kinematics during baseball pitching. Thirty-one youth baseball pitchers (10.87 ± 0.92 years; 150.03 ± 5.48 cm; 44.83 ± 8.04 kg) participated. A strong correlation was found between stance hip rotation and scapular upward rotation at maximum shoulder external rotation (r = 0.531, P = 0.002) and at ball release (r = 0.536, P = 0.002). No statistically significant correlations were found between dynamic hip rotational range of motion and passive hip range of motion. Hip range of motion deficits can constrain pelvis rotation and limit energy generation in the lower extremities. Shoulder pathomechanics can then develop as greater responsibility is placed on the shoulder to generate the energy lost from the proximal segments, increasing risk of upper extremity injury. Additionally, it appears that passive seated measurements of hip range of motion may not accurately reflect the dynamic range of motion of the hips through the progression of the pitch cycle.  相似文献
