Definitions
- the invention relates to the field of evaluating the performance of the rower, and more particularly the measurement of the power developed during a rowing stroke or rowing.
- Athletes often work to improve their performance, regardless of the sport they practice. This requires access to techniques for evaluating their current performance in order to establish a baseline from which to progress. Depending on the sport practiced, it is possible that the performance depends on a large number of parameters such as, for example, a positioning of the athlete's body, a regularity in the effort, but also a quality of synchronization of his performances. gestures with the actions of a team-mate.
- the invention makes it possible to improve at least one of the disadvantages of the state of the art by proposing a system for determining a power produced by a rower, for example in rowing.
- the system includes at least one rowing.
- the rowing comprises a first inertial center (still called usually inertial center) and a second inertia center and cooperates with a boat, which includes a third inertia center.
- the system further comprises a power calculation module, itself comprising:
- a second module for determining a moment of an estimated force on a rowing lady supporting rowing during a partial or full immersion phase of the rowing pad
- a third module for determining a rotation of the first center around a vertical axis of the third central inertia.
- the first inertial center is positioned substantially close to said swimming lady.
- the third inertial center is positioned on a horizontal plane of the boat.
- the first, second and third modules are included in the same computing device.
- the invention also relates to a method in the above-mentioned system for determining a power produced by a rower, the method comprising in particular: a determination of an angular deformation of rowing during all or part of a phase immersion of a palette of this rowing,
- the invention relates to a computer program product loadable directly into the internal memory of a computer comprising portions of software code for executing the steps of the method described above, when said program is executed on a computer . 4. List of figures.
- FIG. 1 shows a system for determining a power produced by a rower in rowing according to a particular and non-limiting embodiment of the invention.
- FIG. 1 represents a system for determining a power produced by a rower in rowing according to a particular and non-limiting embodiment of the invention.
- the boat (boat) BOAT shown in FIG. 1 comprises two OAR oars, only one of which is shown in the figure.
- Each of the OAR oars is carried by a so-called "swimming lady" device which operates as an articulated support and facilitates the movements of the oars, controlled by a rower.
- At least one of the two OAR oars is equipped inertia plants.
- This OAR equipped rowing carries at least two IMU1 and IMU2 inertia plants positioned respectively close to the swimming lady and close to the rowing paddle.
- a third IMU3 inertia station is fixed on a horizontal plane of the BOAT boat.
- the three IMU1, IMU2 and IMU3 inertial units are connected by wireless communication links adapted to communicate according to one or more short-distance communications protocols, with a COMP calculation module and possibly between them.
- the wireless communication protocols implemented are, for example, compatible with the bluetooth standards, WiFi 802.1 1, etc. Of course, these examples are not limiting and any wired or wireless communication interface can be used.
- the calculation model COMP is embarked on the boat (boat BOAT).
- the calculation model can be deported to a nearby craft or established at a distance compatible with a good quality of remote communication with inertia units interfaced to do this.
- the calculation module COMP comprises a plurality of dedicated calculation modules, among which COMP1, COMP2 and COMP3 respectively adapted to a determination S1 of an angular deformation of an OAR oar during all or part of an immersion phase from a range of OAR rowing, to a S2 determination of a moment of an estimated force on a RS swimming lady supporting Rowing OAR during a partial or full immersion phase of the rowing paddle OAR, and an S3 determination a rotation of the first central IMU1 around an axis of the third IMU3 inertial center.
- Each of the modules (or submodules) COMP1, COMP2 and COMP3 conventionally comprises one or more microcontrollers, at least one random access memory called working memory, at least one non-volatile memory called storage memory, a reset circuit and energy monitoring system, one or more external communication buses, one or more communication interfaces in particular compatible with the communication interfaces of the IMU1, IMU2 and IMU3 inertia control panels.
- One of the communication interfaces is adapted to an extraction of the metrology data recorded during the training or competition sessions whose power data determined to the swimming lady. Such extraction can be performed by means of a wired or wireless connection to a device such as a laptop, tablet, smartphone or any other similar equipment configured for reading and / or a more developed exploitation of these data.
- the COMP1, COMP2 and COMP3 modules are merged in a single device.
- the system according to the invention is suitable for determining a PROW power produced by the rower, for example during a rowing stroke OAR, in an ecological situation, that is to say, in a real situation of practice.
- the power PROW expressed to the swimming lady in ecological condition is the most relevant mechanical parameter to quantify and analyze the performance of a rower.
- the rowers also use this PROW parameter as an indicator of the quality of the training during their ergometer sessions.
- technical solutions exist to measure the power produced at the swimming lady, involving using oars and / or instrumented swimming ladies.
- the integration of these sensors during boat sessions is not simple and involves a considerable preparation time of the boat, making the use of these measures complex and for the moment circumscribed at the highest level.
- the systems and methods envisaged according to the invention propose a measurement of the force power PROW developed by the rower via the use of the three IMU1, IMU2 and IMU3 inertial units.
- These plants can very easily be fixed on BOAT boat and OAR rowing, the proposed system is very simple to set up and could be used routinely in training.
- the IMU1, IMU2 and IMU3 inertia control panels can be positioned very quickly and fixed with conventional links, such as self-gripping fastening strips (Velcro) as an example. It is the same for the calculation module COMP when it is embarked aboard the boat BOAT.
- the IMU1, IMU2 and IMU3 inertial units represented in FIG. 1 are advantageously and cleverly configured for calculating the PROW power produced to the swimming lady by determining both the moment of force exerted and the angular speed of the rowing at the level of of the swimming lady.
- the IMU1, IMU2 and IMU3 inertial units each comprise at least three gyroscopes, a three-dimensional accelerometer and a magnetometer cooperating to establish, for each of the inertial units, its situation in a single reference system.
- the first IMU1 inertial unit is positioned on a rigid sleeve of the OAR oar / oar located close to the swimming lady and the second central IMU2 is placed at most close to the oar paddle oar to measure the maximum deformation of rowing.
- the third unit IMU3 is fixed in a horizontal plane of the boat to obtain a rotation about a vertical axis coinciding with that of the swimming lady.
- each of the IMU1, IMU2 and IMU3 control panels is carried out using a clean fixing system. This system must be sufficient to ensure a stable maintenance of the inertial unit respectively to the OAR oar or the boat BOAT.
- the IMU1 and IMU2 inertial units are configured to determine an angular deformation of the oar oar during a rowing stroke. According to the material resistance theory (field of linear elastic deformation), the moment of force applied to the OAR is directly proportional to the angular deformation of the rowing.
- IMU1 and IMU2 control panels Data transmitted by the IMU1 and IMU2 control panels are used to determine this instantaneous angular deformation.
- Each of these two plants uses the data of the three gyroscopes, the accelerometer and the magnetometer that are specific to give the orientation of the inertial unit in a terrestrial reference, at every moment.
- w1 is a scalar corresponding to the value of the rotation around this vector.
- x2, y2 and z2 give the components of the rotation vector of the IMU2 control unit in the terrestrial reference and,
- w2 is a scalar corresponding to the value of the rotation around this vector.
- IMU2 with respect to the IMU1 control unit is determined in two steps using rotation matrices.
- a first step consists in determining a relative orientation of rest, that is to say without loading, between the two inertial units during a static phase without deformation of the OAR.
- This relative rest orientation makes it possible to reset the relative orientation subsequently calculated during a deformation of the rowing because of the power dissipated.
- This relative rest orientation is determined by calculating the rotation matrices giving respectively the orientation of the IMU1 and IMU2 plants in relation to the terrestrial reference marked "0":
- a relative rotation matrix is then determined to characterize the relative orientation between the IMU1 and IMU2 inertial units arranged on the OAR.
- IMU1 and IMU2 at any moment.
- the theory of the resistance of materials indicates that the angular deformation is linearly related to the moment of force applied in the field of linear elastic deformation.
- a calibration is performed to obtain a linear relationship between the average angular deformation and a moment of strength estimated at the swimming lady.
- a and b are coefficients determined by linear regression. Assuming a value of zero force moment for zero angular deformation, the value of the constant b is set to 0 and removed from the previous equation. The power of the moment of force exerted on the handle
- the IMU3 inertial unit is fixed in the horizontal plane of the boat BOAT to obtain a rotation about a vertical axis coincide with that of the swimming lady supporting the OAR.
- a procedure similar to that explained above is used to determine an instantaneous rotation of the train around a vertical axis of the boat.
- a new rotation matrix can be calculated at
- central IMU1 in the terrestrial reference is the transpose of the rotation matrix
- inertial IMU1 around the vertical axis of the IMU3 inertial unit assumed parallel to that of the swimming lady.
- the invention does not concern the only embodiment described but applies to any system comprising a module for determining an angular deformation of a train or an oar during all or part of a phase of immersion of a paddle of this oar, a module for determining a moment of an estimated force on a rowing lady supporting rowing during a partial or full immersion phase of the rowing paddle, and a module for determining a rotation of the first inertia center around a vertical axis of the third inertia center.
- the invention also applies to any method of determining a power dissipated during a rowing stroke or rowing comprising the three steps of determination above.
