###### Abstract
This new impulse has paved the way for new opportunities and challenges for the research and development of wearable devices into four major clusters: health, sports, daily physical activity, tracking and localization, and safety. Figure 1: Outline of IoT system. IoT technology, low-power wearable device development, and Data Acquisition (DAQ) are becoming increasingly commonplace in many sports [17; 18; 19; 20]. One widely used device in these systems is the Inertial Measurement Unit (IMU--further explored in Section 5.1). Additionally, IMUs can be integrated with heart rate monitor systems, Global Navigation Satellite Systems (GNSS--further explored in Section 6.2) terminals, and sometimes frequency and force sensors. For example, kinematic DAQs, relying on GNSS and IMU or Ultra-wideband-based location systems (UWB--further explored in Section 6.1.3), are widely used in team sports such as rugby or football [21; 22] to measure the position and displacement of the athletes on the pitch. Dynamic parameters can also be measured (e.g., the forces exerted on the oars in rowing [23] or on the paddle in flatwater kayaking [18; 24]) employing strain gauge bridges, together with kinematic ones. Considering that the latest versions of these applications are becoming more performant from this point of view, the accuracy and reliability of collected data have always been even more crucial [25]. In this context, the essential point by the coaches is to pay attention to discriminating relevant data from countless pieces of information [25]. This technology, widely employed in sports activities monitoring, has found applications in home-based telemedicine, especially suited for the population affected by chronic diseases, mainly if used together with cloud systems [25]. In the clinical area, wearable sensors and technologies are becoming valuable for physicians and physiotherapists to learn the patients' movements and design their rehabilitation methods [26]. Changes in daily physical activities, such as time spent walking, distance, pace, speed, elevation, calories burned, and heart rate, are easily accessible even by smartphone apps or worn waistbands and skin patches connected to it via radio links. They can measure different aspects of performance during all kinds of physical activities [27]. Furthermore, IoT has played a significant role in developing the Internet of Medical Things, facilitating remote healthcare, edible sensor tracking, and mobile health applications. This integrated system enables the measurement of vital signs, which is crucial for physicians to monitor and assess patients' well-being remotely. In this study, over 250 papers were selected through a search strategy considering the keywords related to the field of human performance assessment, modern technologies, and devices to underline the actual state of human movements monitoring in different conditions, looking to identify the actual advances in sports technology applicable in sport, wellbeing, and clinical field published in the last five years. Differently from the current literature, in which the authors focused on specific devices such as wearable sensors to mainly monitor sport and fitness performance [28; 29; 30], this review aims to provide a wide global vision of the recently available technologies that are applied in sport, fitness, and clinical fields to monitoring human motion performance.
