1. An ergometric treadmill for sport training comprising a screen, a control system and a system configured for collecting, processing, analyzing and visualizing a biomechanical response of a user while running on the ergometric treadmill, wherein the system comprises:
(a) a plurality of microelectromechanical system (MEMS) acceleration sensors attached by supports to the ergometric treadmill connected to a data capture unit comprising a micro-controller with ports for sending and receiving data, at least one memory, and at least one program comprising a plurality of instructions which, when executed by the micro-controller, cause the data capture unit to:
(1) initialize and calibrate the plurality of MEMS acceleration sensors disposed in their respective supports when the ergometric treadmill initializes and at the start of each run;
(2) filter signals sent by each of the plurality of MEMS acceleration sensors to minimize noise and interference;
(3) temporarily synchronize accelerometry signals from the plurality of MEMS acceleration sensors to send the signals from the plurality of MEMS acceleration sensors as a whole and grouped to the data processing unit; and
(4) monitor the data from the plurality of MEMS acceleration sensors to request the MEMS accelerations sensors to restart in event of a problem or a failure in readings therefrom;
(b) a data processing unit comprising a processor and at least one memory that stores at least one program that includes instructions that, when executed by the processor, cause the data processing unit to:
(1) receive data from the data capture unit and the control system of the ergometric treadmill;
(2) generate a plurality of parameters related to physical exercise performed on the ergometric treadmill by the user, wherein the plurality of parameters is calculated for left and right legs of the user, man average value of both the left and the right legs of the user, and an asymmetry level between both the left and the right legs of the user; and
(3) synthesize and show the plurality of parameters generated in (b)(2) in graphic form in form of a loop by the screen of the ergometric treadmill.
