Abstract: A computerized method performed by a processor, an apparatus and a computer program product the method comprising: receiving a model associated with a baseline of one or more biomechanical parameters of one or more action types of a subject, the model describing the biomechanical parameters during a first time period; obtaining one or more values characterizing the biomechanical parameter of the action type in an uncontrolled environment during a second time period, the second time period being later than the first time period; determining whether the value characterizing the biomechanical parameter during the second time period are in compliance with the model; and outputting an alert if the values are not in compliance with the model.

Abstract: A system, method and footwear sensor unit a footwear sensor unit removably attachable to footwear, the footwear sensor unit including: an Inertial Measurement Unit (IMU) including a 3-axis accelerometer and a 3-axis gyroscope, the IMU adapted to gather sensor data of detected movements of the footwear; and a storage device in electronic communication with the IMU, the storage device for storing the sensor data; and a communications module in electronic communication with the storage device, the communication module configured to transmit data to an external computing device.

Abstract: A method and system are disclosed using a position sensor for tracking a trajectory of a paddling instrument. Optionally the trajectory may be used for determining a paddling improvement strategy, for recognizing a stroke type, for coordinating a rowing team and/or for calculating a paddling force.
