The main objectives of this research will be analyse the relationship between external load parameters (accelerometery) with the internal load response (electromyography) in specific actions of collective sports (Thorlund, Aagaard & Madsen, 2009). Create an algorithm to obtain useful indicators for the control and quantification of the load, based on the existing relationship between the accelerometery and electromyographyCiencias de la Actividad Física y del Deport
