Body sensor networks for monitoring performances in sports: A brief overview and some new thoughts (original) (raw)

An initial experience in wearable monitoring sport systems

Proceedings of the IEEE/EMBS Region 8 International Conference on Information Technology Applications in Biomedicine, ITAB, 2010

Until recent years most research involving the capture and analysis of biometric and/or physiological signals have been limited to a laboratory or otherwise controlled environment. Wearable technologies introduced a refinement to personal signal capturing by permitting a long-term onperson approach. Sensors, integrated circuits, textile integration and other elements are directly responsible for advancements in this area; however, in spite of the present progress there are still a number of obstacles to overcome for truly achieving seamless wearable monitoring technology (WMT). This article presents an overview of a generic monitoring systems architecture based on designs found in recent literature and commercially available solutions. A custom implementation based on commercially available components and evaluation boards is also presented, including some obtained data in varying body locations and/or activities.

Smart garments for performance and training assessment in sport

Proceedings of the 4th International Conference on Wireless Mobile Communication and Healthcare - "Transforming healthcare through innovations in mobile and wireless technologies", 2014

This paper describes a novel method and system to monitor and compute swimmer performance. We placed a 3-axes accelerometer onto the athlete's back. This accelerometer allows for detecting and interpret single gestures during the training session. The acquired data can be processed to compute synthetic parameters for a qualitative assessment of the performance. Symmetry and no. of foot-/arm-stroke integrate the measurement. 3 healthy volunteers (1 male, 2 females) participated to the system validation. The system proved a fine detection of each phase and movement in the analyzed sport. Also comfort and wearability was positively assessed.

Wireless Sensor Devices in Sports Performance

Sensor devices are an integral part of human movement analysis. The use of sensors in sports performance and injury prevention is extremely useful. Over the years wireless systems have become increasingly popular and the analysis of human movement has been therefore simplified. Inertial measurement units are very popular in physical activity monitoring and have become readily available for consumers. The use of more advanced sensors to measure electrical and mechanical muscle activity tend to be tethered devices, thus data collection on more complex movements is limited. This paper looks at the need for wireless solutions to these sensors and the proposal for a multi-channel sensor which incorporates all the necessary sensors for complete human movement analysis. Wireless systems have the advantage of allowing the participant or athlete to perform the movement in their ecologically valid environment while giving both reliable and accurate results to the practitioner. In terms of human movement, to achieve accurate information about the position, kinematic and external forces of the segments of the body being studied, a single multi-channel sensor device is necessary. The combination of sensors in one device can give accurate information on muscle activity, forces, directionality and acceleration.

Design , manufacturing and test of a wearable device to monitor athlete ' s body movements

2021

In this paper a device based on wearable sensors is introduced to describe quantitative body movements in different sports. This device can be an alternative of Image processing techniques. Image processing devices have always been used to describe quantitative body movements, which in addition to being costly, have to be used in specific conditions. The device is built from a number of wireless modules that are easy to use in real-world environments with no limitations. In this method, a quantitative description of movement is made by wireless modules and is performed by the data collected from these modules. In order to analyze the data that was extracted from an athlete's body movements with these wearable sensors, the outputs are simulated in Matlab, and some of its kinematic and kinetic parameters have been studied. Then, at the end of this paper, the quality of movement of a professional athlete and a beginner athlete are compared, and the result is shown. Kinematic and dy...

In-situ Athlete Monitoring: Data Collection, Interpretation & Feature Extraction

2018

:The original core question of this thesis related to the real-time wireless collection of data from teams of athletes, in essence a technology - engineering issue. However, as time progressed, more fundamental questions evolved: What data is being collected, what does the data mean and how should it be interpreted? This question lies on the intersection of human movement studies, in the form of biomechanical & physiological sports science, and digital signal processing. The key biomechanical and physiological questions also feed back into the original real-time data collection issue. If data collected from athlete-mounted transducers1 is correctly interpreted, the salient features can be extracted and subsequently stored or transferred across a wireless network to a host system for analysis. Consequently this thesis addresses two intertwined issues, the real time in-situ data collection and the data processing necessary to extract some specific information useful to sports scientis...

Team Fitness Monitoring for Field Hockey Using In-vivo Sensor and Multiple Sinks

In any sport, where many players work as team, the fitness level of every single player directly affects the overall performance of the team. Beside injuries and many other game related illnesses, the most problematic thing that players usually suffer from is the muscle fatigue. Scientists are sure that the level of fatigue in an over worked muscle can be measured by measuring PH value of the blood. This is because an overburdened muscle has slightly acidic PH value than normal. This acidity is due to the production of excess lactic acid in the blood. In this research work we use in-vivo sensors to measure fatigue in field hockey players and then transmit that information to health officials of the hockey team using Wireless Body Area Network (WBAN). WBAN in our proposed design consists of multiple sinks mounted around the ground.

A Sports Technology Needs Assessment for Performance Monitoring in Swimming

Procedia Engineering, 2013

In recent years, technology has played an increasing role in many sports, including swimming. Far beyond the stopwatch and hand marked events, detailed biomechanical attributes can be measured using technology such as instrumented blocks, wire tethers and underwater/dolly cameras. With the advent of micro-technology, there has been an increasing trend toward the use of wearable sensors such as heart rate monitors, cadence aids and -more recently -activity monitors. The micro-electromechanical system (MEMS)-based inertial sensor class of activity monitor is of particular interest to the CWMA (Centre for Wireless Monitoring and Applications) at Griffith University.
