With the rapid advances in sports technologies, athletes and sports coaches are constantly searching for improved performance assessment methods. Whilst athletic performances continue to improve, accurate training prescription and feedback is important to the consistency of the training outcome and maintaining the performance margin. Traditionally, the measurement of elite athlete performance is performed...
The recent growth in popularity in sport climbing is partly due to the safe environment provided by indoor climbing walls, particularly for novice climbers. Sport climbing involves a wide range of skills and abilities. The purpose of this paper is to present a wearable sensing platform and an analysis framework for assessing general climbing performance during training. To provide the required freedom...
The key to a long healthy life is the adoption of a balanced diet and regular exercise. The paper describes the use of a Body Sensor Network (BSN) for real-time corrective feedback during the performance of an exercise routine. The feedback utility will log important parameters during an exercise session to allow one to keep track of fitness progress. Inclusion of vital sign sensors such as pulse...
A 2.4 GHz low-power wireless platform based on the Texas Instrumentstrade CC2431 System-On-Chip (SOC) transceiver is used to conduct a preliminary investigation of the accuracy of a 3-axis accelerometer fused with a linear encoder for capturing high-speed motion. Calibration of the fused sensors is accomplished by extracting the gravity related term from the accelerometer when it is under static conditions...
We describe the use of upper leg mounted force sensitive resistors (FSR) to analyze muscle activity during bicycling. We demonstrate that FSRs can provide information that is not accessible to motion sensors, like the gear in which a person is cycling or rather the amount of force applied to the pedals. This is exemplary for many other activities where the effort and subtle muscle activities patterns...
This paper presents a new algorithm for real time tracking the flexion angle from wearable accelerometer sensor data using wireless body sensor network (BSN). The proposed algorithm uses dynamic filter for tracking the flexion angles of which the human body dynamics is described by its system model. In this work, the Extended Kalman Filtering is used to demonstrate the superiority of this approach...
The idea of ldquoPhysical Exercises (PEs) homeworkrdquo has been introduced to encourage children and potential young athletes to stay physically active outside of classroom and to keep up with training. However, it is not practical to assume all parents are willingly and responsible enough to supervise home PE sessions. To turn the concept of managed PE homework into a reality, an automated solution...
A novel air jet indentation system with the combination of the optical coherence tomography (OCT) technique was presented in this paper for the quantitative measurement of mechanical properties of soft tissues. The key idea of this method is to use a pressure-measured air jet as an indenter to compress the soft tissue and utilize the OCT signals to extract the deformation induced. Experiments were...
Heart rate monitoring related to dynamic movements can be a crucial indicator of individual health according to recent researches. It makes it important to found a real-time system for automatic recordings of heart rate variability and physical activity. In this paper, we developed a distributed and synchronized intelligent sensor system using a single, waist-mounted triaxial wireless accelerometer...
