Monitoring variations in the functioning of the autonomic nervous system may help personalize training of runners and provide more pronounced physiological adaptations and performance improvements. We systematically reviewed the scientific literature comparing physiological adaptations and/or improvements in performance following training based on responses of the autonomic nervous system (ie, changes in heart rate variability) and predefined training. PubMed, SPORTDiscus, and Web of Science were searched systematically in July 2019. Keywords related to endurance, running, autonomic nervous system, and training. Studies were included if they (a) involved interventions consisting predominantly of running training; (b) lasted at least 3 weeks; (c) reported pre- and post-intervention assessment of running performance and/or physiological parameters; (d) included an experimental group performing training adjusted continuously on the basis of alterations in HRV and a control group; and (e) involved healthy runners. Five studies involving six interventions and 166 participants fulfilled our inclusion criteria. Four HRV-based interventions reduced the amount of moderate- and/or high-intensity training significantly. In five interventions, improvements in performance parameters (3000 m, 5000 m, Loadmax, Tlim) were more pronounced following HRV-based training. Peak oxygen uptake () and submaximal running parameters (eg, LT1, LT2) improved following both HRV-based and predefined training, with no clear difference in the extent of improvement in . Submaximal running parameters tended to improve more following HRV-based training. Research findings to date have been limited and inconsistent. Both HRV-based and predefined training improve running performance and certain submaximal physiological adaptations, with effects of the former training tending to be greater. 相似文献

Improving Surgical Training is a programme piloting an innovative, evidence-based approach to training. It was developed in response to the Shape of Training report which reviewed postgraduate training and recommended changes in medical education to meet the demands of the modern NHS. A series of initiatives have been developed to enhance the experience for surgical trainees not only to encourage a more focussed and supported method, but also to improve their job satisfaction. The initiatives have combined a greater emphasis on time for training provided by trainers with allocated time for training with multidisciplinary teamworking and the use of technology enhanced learning with simulation of both technical and non-technical skills. The pilot started in 2018 with core training in general surgery and has been expanded to include vascular surgery, urology and trauma and orthopaedics over the last 2 years. Initial feedback from both trainees, trainers and schools of surgery have identified different challenges to aid implementation. The programme is being very carefully evaluated by an independent company as well as careful oversight by the General Medical Council which are paramount to its success. 相似文献

A presentation is made of 12 cases that have a full and detailed clinical history and physical examination, which are essential for obtaining optimal diagnostic-therapeutic planning for quality care. Furthermoe, education in values focused on the patient is considered as another of the essential objectives to be transmitted in university faculties and hospitals. This article, based on anonymised real cases, aims to provide small brushstrokes in this regard, hoping that they will be useful. 相似文献

目的调查镇江市各医院护士分层培训及分层进阶的方法及现状。方法2018年4—5月间采用自行设计的调查问卷,对全市医院的护理人员进行随机抽样调查。结果调查显示镇江市96.45%的护士受医院分层培训及分层进阶这一模式的管理。其中N1占16.77%,N2占29.5%,N3占41.9%,N4占8.7%,其他占3.11%。有24.53%的护士对医院目前的分层培训方式感到满意并认为无需改进,40.99%的护士表示满意,但需要改进,29.19%的护士表示基本满意,需要改进,5.28%的护士表示不满意需要较大改进。95.82%的医院科室对不用层级的护士有不同的核心能力要求并根据不同核心能力要求进行培训。结论护士分层培训几分层进阶这一管理模式在镇江各医院都有体现,但各医院实行的方式有较大差异,配套的管理方式也有待完善。 相似文献

BackgroundA number of key publications in recent years have advocated a more integrated vision of UK primary care involving increased multi-professional communication and understanding. This has resulted in a marked change in the roles being undertaken by pharmacists. Community pharmacists have traditionally provided a medicine supply function and treated minor ailments in addition to delivering a suite of locally commissioned services; however these functions have not necessarily been part of a programme of care involving the other clinicians associated with the patient. An integrated model of care would see much closer working between pharmacy and general practice but also with pharmacists not only working with, but in the practice, in an enhanced patient-facing role, trained as independent prescribers. This has implications for the dynamics amongst professionals in this environment.ObjectivesThis exploratory multiple case study attempts to explore these changing dynamics across ten GP surgeries throughout the South-East of England.MethodsSemi-structured, in-depth interviews were conducted with one nurse, one pharmacist and one physician from each clinic, and survey data was collected from 38 patients who had appointments with a pharmacist.ResultsThe data suggested that the pharmacists who had enhanced roles perceived some uncertainty about their professional role and identity, which resulted in instability and insecurity and that this uncertainty led to both professional and interprofessional tension with their primary care colleagues. The survey data revealed that n = 35 (92%) patients stated they were ‘very satisfied’ or ‘satisfied’ with their appointment. And n = 37 (97%) were ‘very comfortable’ or ‘comfortable’ discussing their medications with the pharmacist. In addition, 36 patients (95%) reported that they strongly agreed or agreed with the clinical recommendations made by the pharmacist.ConclusionsThese findings are discussed in relation to role expansion and professional/interprofessional relations before key practical suggestions are offered. 相似文献
