Inertial measurement unit and biomechanical analysis of swimming: an update

Kamiar Aminian, Farzin Dadashi, Grégoire Millet

The biomechanical analysis of swimming always faced impeding factors of measurement in the aquatic environment. Our current knowledge of swimming locomotion is very much owing to employing video cameras to capture the body kinematics. Nevertheless, the rec ...

Gaussian process framework for pervasive estimation of swimming velocity with a body-worn IMU

Kamiar Aminian, Grégoire Millet, Farzin Dadashi

Presented is an accurate swimming velocity estimation method using an inertial measurement unit (IMU) by employing a simple biomechanical constraint of motion along with Gaussian process regression to deal with sensor inherent errors. Experimental validati ...

Front-Crawl Instantaneous Velocity Estimation Using a Wearable Inertial Measurement Unit

Kamiar Aminian, Grégoire Millet, Farzin Dadashi, Florent Crettenand

Monitoring the performance is a crucial task for elite sports during both training and competition. Velocity is the key parameter of performance in swimming, but swimming performance evaluation remains immature due to the complexities of measurements in wa ...

In-field objective evaluation and analysis in ski jumping using inertial sensors

Julien Chardonnens

Ski jumping, a prestigious Olympic discipline, has been constantly evolving. Over the years, the biomechanics fundamentals of this highly technical sport have been intensively documented by investigating the jump timing, kinematics, dynamics and motor cont ...

Conjugate momentum estimate using non-linear dynamic model of the sit-to-stand correlates well with accelerometric surface data

Kamiar Aminian, Raluca Lidia Ganea

The purpose of this study was the development of a non-linear double inverted constrained pendulum model for the analysis of the movement of sit-to-stand (STS) transition. Ten able-bodied subjects perform five trials in their natural speed. Kinematics, kin ...

Front-Crawl Propulsive Phase Detection Using Inertial Sensors

Kamiar Aminian, Grégoire Millet, Farzin Dadashi, Florent Crettenand

Front crawl is an alternating swimming stroke technique in which different phases of arm movement induce changes in acceleration of limbs and body. This study proposes a new approach to use inertial body worn sensors to estimate main temporal phases of fro ...

Optimization of two GPS/MEMS-IMU integration strategies with application to sports

Jan Skaloud, Adrian Wägli

The application of low-cost L1 GPS receivers integrated with micro-electro-mechanical system (MEMS) inertial measurement units (IMU) allows the continuous observation of position, velocity and orientation which opens new possibilities for comparison orf at ...
