Wearable technology has added a whole new dimension in the healthcare system by real-time continuous monitoring of human body physiology. They are used in daily activities and fitness monitoring and have even penetrated in monitoring the health condition of patients suffering from chronic illnesses. There are a lot of research and development activities being pursued to develop more innovative and reliable wearable. This chapter will cover discussions on the design and implementation of wearable devices for different applications such as real-time detection of heart attack, abnormal heart sound, blood pressure monitoring, gait analysis for diabetic foot monitoring. This chapter will also cover how the signals acquired from these prototypes can be used for training machine learning (ML) algorithm to diagnose the condition of the person wearing the device. This chapter discusses the steps involved in (i) hardware design including sensors selection, characterization, signal acquisition, and communication to decision-making subsystem and (ii) the ML algorithm design including feature extraction, feature reduction, training, and testing. This chapter will use the case study of the design of smart insole for diabetic foot monitoring, wearable real-time heart attack detection, and smart-digital stethoscope system to show the steps involved in the development of wearable biomedical systems.
可穿戴技术通过对人体生理的实时连续监测,为医疗保健系统增加了一个全新的维度。它们用于日常活动和健康监测,甚至已渗透到监测慢性疾病患者的健康状况。为了开发更创新、更可靠的可穿戴设备,人们正在进行大量的研究和开发活动。本章将讨论不同应用的可穿戴设备的设计和实现,如心脏病发作的实时检测,异常心音,血压监测,糖尿病足监测的步态分析。本章还将介绍如何将从这些原型中获取的信号用于训练机器学习(ML)算法,以诊断佩戴该设备的人的状况。本章讨论了以下步骤:(i)硬件设计,包括传感器选择、表征、信号采集和与决策子系统的通信;(ii)机器学习算法设计,包括特征提取、特征约简、训练和测试。本章将以糖尿病足监测智能鞋垫、可穿戴式实时心脏病检测和智能数字听诊器系统的设计为例,展示可穿戴式生物医学系统的开发过程。

People have been searching for the good life or personal well-being since the ancient Greeks. During this same period, people have been expressing themselves through sport, participating in games of athleticism as a means of discovering who they are and reaching their potential. This chapter examines the relationship between sports and a flourishing life. By examining sports as a mechanism of achieving specific traits of positive psychology associated with flourishing, the researcher is able to determine that sports are a matrix in which human potential can be nourished.

Challenges and Future of Wearable Technology in Human Motor-Skill Learning and Optimization 可穿戴技术在人类运动技能学习与优化中的挑战与未来
Pub Date : 2020-02-25 DOI: 10.5772/intechopen.91356

Learning how to move is a challenging task. Even the most basic motor skill of walking requires years to develop and can quickly deteriorate due to aging and sedentary lifestyles. More specialized skills such as ballet and acrobatic kicks in soccer require “talent” and years of extensive practice to fully master. These practices can easily cause injuries if conducted improperly. 3D motion capture technologies are currently the best way to acquire human motor skill in biomechanical feedback training. Owing to their tremendous promise for a plethora of applications, wearable technologies have garnered great interest in biofeedback training. Using wearable technology, some physical activity parameters can be tracked in real time and a noninvasive way to indicate the physical progress of a trainee. Yet, the application of biomechanical wearables in human motor-skill learning, training, and optimization is still in its infant phase due to the absence of a reliable method. This chapter elaborates challenges faced by developing wearable biomechanical feedback devices and forecasts potential breakthroughs in this area. The overarching goal is to foster interdisciplinary studies on wearable technology to improve how we move.
学习如何移动是一项具有挑战性的任务。即使是最基本的步行运动技能也需要多年的发展,并且由于年龄的增长和久坐不动的生活方式会迅速退化。更专业的技能,如芭蕾和足球中的杂技踢腿,需要“天赋”和多年的广泛练习才能完全掌握。如果操作不当,这些做法很容易造成伤害。三维动作捕捉技术是目前生物力学反馈训练中获取人类运动技能的最佳途径。由于其巨大的应用前景,可穿戴技术在生物反馈训练中引起了极大的兴趣。使用可穿戴技术,可以实时跟踪一些身体活动参数,以一种无创的方式来指示受训者的身体进步。然而,由于缺乏可靠的方法,生物力学可穿戴设备在人类运动技能学习、训练和优化方面的应用仍处于起步阶段。本章阐述了开发可穿戴生物力学反馈设备所面临的挑战,并预测了该领域的潜在突破。总体目标是促进可穿戴技术的跨学科研究,以改善我们的运动方式。

Sport for Development and Peace: Current Perspectives of Research 体育促进发展与和平:目前的研究观点
Pub Date : 2019-11-18 DOI: 10.5772/intechopen.89192
T. Gadais
Sport for Development and Peace (SDP) is an international movement that began in the 2000s with the Millennium Development Goals (2000–2015) and is currently continuing around the United Nations’ Sustainable Development Goals 2015–2030, driven by international organizations such as UNESCO. Often located in an international development context, organizations and associations use sport as a vehicle to reach several social and humanitarian missions (e.g., education, social cohesion, health, reintegration, diplomacy, and peace). This chapter presents the origins and objectives of the SDP, but it also looks at current research in the field. Since 2010, studies have significantly increased in the field around four main areas (macrosociological, field explorations, program management and evaluation, and literature reviews). This chapter also provides illustrations of SDP research projects, axis of tensions between practice and theory, and perspectives for future research in the field.
体育促进发展与和平(SDP)是一项国际运动,始于2000年的千年发展目标(2000-2015),目前在联合国教科文组织等国际组织的推动下,围绕联合国2015-2030年可持续发展目标继续进行。各组织和协会往往位于国际发展背景下,利用体育作为实现若干社会和人道主义使命(如教育、社会凝聚力、卫生、重返社会、外交与和平)的工具。本章介绍了SDP的起源和目标,但也介绍了该领域的当前研究。自2010年以来,该领域的研究在四个主要领域(宏观社会学、实地探索、项目管理和评估以及文献综述)显著增加。本章还提供了SDP研究项目的插图,实践与理论之间的紧张轴线,以及该领域未来研究的观点。

Smart Wearables for Tennis Game Performance Analysis 用于网球比赛表现分析的智能可穿戴设备
Pub Date : 2019-10-09 DOI: 10.5772/intechopen.89544
M. Kos, I. Kramberger
For monitoring the progress of athletes in various sports and disciplines, several different approaches are nowadays available. Recently, miniature wearables have gained popularity for this task due to being lightweight and typically cheaper than other approaches. They can be positioned on the athlete’s body, or in some cases, the devices are incorporated into sports requisites, like tennis racquet handles, balls, baseball bats, gloves, etc. Their purpose is to monitor the performance of an athlete by gathering essential information during match or training. In this chapter, the focus will be on the different possibilities of tennis game monitoring analysis. A miniature wearable device, which is worn on a player’s wrist during the activity, is going to be presented and described. The smart wearable device monitors athletes’ arm movements with sampling the output of the 6 DOF IMU. Parallel to that, it also gathers biometric information like pulse rate and skin temperature. All the collected information is stored locally on the device during the sports activity. Later, it can be downloaded to a PC and transferred to a cloud-based service, where visualization of the recorded data and more detailed game/training statistics can be performed.
为了监测运动员在各种运动和学科中的进步,现在有几种不同的方法可用。最近,微型可穿戴设备由于重量轻且通常比其他方法便宜而在这项任务中受到欢迎。它们可以放置在运动员身上,或者在某些情况下,这些设备被整合到运动必需品中,如网球拍把手、球、棒球拍、手套等。他们的目的是通过在比赛或训练中收集基本信息来监测运动员的表现。在本章中,重点将放在网球比赛监测分析的不同可能性上。将展示和描述一种微型可穿戴设备,在活动期间佩戴在玩家的手腕上。智能可穿戴设备通过采样6自由度IMU的输出来监测运动员的手臂运动。与此同时,它还能收集脉搏和皮肤温度等生物特征信息。在体育活动期间,所有收集到的信息都会本地存储在设备上。之后,它可以下载到PC上,并转移到基于云的服务中,在那里可以执行记录数据的可视化和更详细的游戏/训练统计。

The modern phenomenon of tourism is more focused on specific forms of tourism in which sports and health tourism play a very important role. That fact is not surprising having in mind that they represent interconnected activities that complement each other and give each other completely new dimension. On one side, sports and health represent very important content of tourist offer because of the fact they enable tourists to become active participants in various activities, and on the other side, they represent important driving force for visiting particular destination. The idea of this chapter is to provide a theoretical and practical framework of this issue with a special focus on case study of Montenegro. According to the results of the research that was carried out, the general conclusion is that Montenegro has extremely valuable natural resources and potentials for the development of sports and health tourism, but there are still a lot of challenges that should be faced in the future in order to improve the quality of tourist offer and the level of tourists’ satisfaction as well as to create completely new image of the destination and position it as high-quality sports and health tourist destination on international market.
现代旅游现象更多地集中在特定的旅游形式上,其中体育旅游和健康旅游发挥着非常重要的作用。这一事实并不令人惊讶,因为它们代表着相互关联的活动,相互补充,并赋予彼此全新的维度。一方面,体育和健康是旅游报价中非常重要的内容,因为它们使游客成为各种活动的积极参与者,另一方面,它们是访问特定目的地的重要动力。本章的想法是为这一问题提供一个理论和实践框架,特别侧重于黑山的案例研究。根据所进行的研究结果,总的结论是黑山拥有极其宝贵的自然资源和发展体育和保健旅游的潜力。但要提高旅游服务质量和游客满意度,塑造旅游目的地的全新形象,在国际市场上定位为高品质的体育健康旅游目的地,在未来还需要面对许多挑战。
