BackgroundRegular exercise is beneficial for adults with cardiovascular disease (CVD) and CVD risk factors. Tai Ji Quan is popular among older adults and may offer additional exercise options. The present article aims to review the scientific literature published within the past decade on Tai Ji Quan as an exercise modality to prevent and manage CVD.MethodsAn electronic literature search of four databases (PubMed, CINAHL, PsycINFO, and AMED) was conducted from April 2003 through March 2013. Studies that examined Tai Ji Quan, were published in English, and specified a target study population of participants with a known CVD condition (e.g., coronary artery disease, chronic heart failure, or stroke) or studies conducted among participants with a CVD risk factor (e.g., hypertension, dyslipidemia, or impaired glucose metabolism) were included.ResultsA total of 20 studies met the inclusion criteria: 11 randomized clinical trials, seven quasi-experimental studies and two cross-sectional studies. The effect of Tai Ji Quan was examined on more than 20 different study variables among persons with coronary artery disease (n = 5 studies), chronic heart failure (n = 5 studies), stroke (n = 4 studies), and CVD risk factors (n = 6 studies). These studies were conducted primarily in Asia (n = 9, 45%) or the United States (n = 8, 40%). Overall, participants enrolled in Tai Ji Quan had better outcomes, though mixed results were reported.ConclusionCollectively, these studies indicate that Tai Ji Quan is a safe form of exercise to prevent and manage CVD. Further research is needed with more rigorous study designs, larger sample sizes, adequate Tai Ji Quan exercise doses, and carefully chosen outcome measures that assess the mechanisms as well as the effects of Tai Ji Quan, before widespread recommendations can be made.  相似文献

Many children and adolescents who require psychiatric hospitalization have been physically or sexually abused, yet the association between reported histories of abuse and the complexity and severity of mental illness among psychiatrically hospitalized youth is poorly described with regard to current inpatient psychiatric practice. We sought to determine the association between histories of abuse and psychiatric complexity and severity in psychiatrically hospitalized youth including comorbidity patterns, psychotropic medication use, reason for admission and length of hospitalization. A systematic chart review was performed on 1433 consecutive psychiatric hospitalizations of children and adolescents that occurred over a 10-month period. Children with a history of abuse were more likely to be diagnosed with multiple DSM-IV-TR disorders than non-traumatized children. A history of sexual abuse was associated with more medication use than in their non-traumatized peers and a higher likelihood of treatment with antipsychotic medications, both at admission and discharge. Physical and sexual abuse were independently associated with increased length of stays, with exposure to both physical and sexual abuse associated with a 2-day increase in duration of hospitalization compared to non-traumatized patients. The findings from this study draw attention to the adverse impact of abuse on psychiatric morbidity and complexity and suggest the need for trauma-informed treatment in psychiatric hospital settings.  相似文献

Information technology has recently seen a huge progress in innovative healthcare technologies that rendered healthcare data bigger. Connectivity on 7/24 basis between human to device and device to device have a crucial role in individuals’ lives. Therefore, Mobile Cloud System (MCC) has become an indispensable tool. Parallel with the rapid developments in the Internet of Things, convergence has become an important issue. Our proposed method, accordingly, can be converged with mobile-cloud environments with cloud computing in handling healthcare information. This study uses Virtual Dedicated Server (VDS) as 4 VCPU and 8 GB RAM and proposes a model based on the Android based mobile phones for stroke patients with cardioembolic (689) and cryptogenic (528) subtypes. The system set up through this study has two basic application elements which are mobile application and server application. Artificial Neural Network (ANN) module is beneficial for classifying the two stroke subtypes while server application is used for saving the data from the patients. Accordingly, our model guarantees availability, security, and scalability as a system for stroke patients applying Stroke dataset for ANN algorithm, Multilayer Perceptron Algorithm (MLP), which has been done for the first time in literature with big data in this scope. The main contributions are: (1) The outcomes will display an individual unique social insurance framework. (2) The outcomes will be utilized for the distinguishing proof of stroke-related data to be gathered by cell phones that are Android based. (3) Stroke patients will find out about their condition of well-being through an ANN application programming interface, which will provide a sort of organization for the patients. Overall, an efficient and user-friendly stroke determination human services framework has been presented through this Healthcare System for patients.  相似文献

本研究采用文献资料法,专家访谈法、问卷调查法、实验研究法等研究方法,以12名上海市14-17岁二、三线青少年男性蝶泳运动员作为受试对象,将实验对象平均分为实验组和对照组,对实验组进行为期两个月的“2-4-2”水陆核心稳定力量训练,对照组进行“2-4-2”常规力量训练。分别在实验干预前后测定受试者八级腹桥测试、15米蹬壁蝶泳腿成绩、50米蝶泳成绩、100米蝶泳成绩、100米蝶泳后15米分段成绩和平均划频、划幅、游速。研究结果显示,水陆核心稳定力量训练可以有效提高青少年蝶泳运动员的八级腹桥测试、15米蹬壁蝶泳腿成绩、50米蝶泳成绩和100米蝶泳后15米分段成绩以及平均划频、游速,表明本研究所采用的水陆核心稳定力量训练模式对提高青少年蝶泳运动员的专项成绩具有积极的作用。  相似文献

长期以来,我国外语写作教学一直沿用传统的教学方法,即“学生单独写作,教师单独批阅”这样一种单向式交流的模式。而“写长法”教学则通过逆向思维的方式,鼓励学生“长长地写”,能写多长就写多长,并且不纠缠错误。这种“长写作”为今后学生有思想的短写作打下了坚实的基础,真正发挥以写促学的功效,从而促成外语学习中听、说、读、写等外语综合运用能力的全面提高,有效地建构外语教学。  相似文献

对世界优秀女子标枪运动员的投掷步步幅、速度和投掷成绩进行初步研究发现:投掷步第二步速度对交叉步保持和利用已获得的速度具有很重要的意义,而投掷步第二步步幅又与第二步和交叉步速度密切相关.研究结果表明:适当缩小投掷步第二步步幅,有利于进一步完善投掷步步幅节奏、加快投掷步速度节奏,为提高标枪运动成绩创造良好条件.  相似文献
