    Direct jump valuation deviceFIELD OF THE INVENTION

    This invention relates to a device for measuring and detecting the capacity of 5 vertical jump directly, being applicable in the sports and school field for the assessment of the physical condition and method of dosing the training load.

    STATE OF THE TECHNIQUE 10

    One of the main points of interest in the field of physical and sports performance are the dosing of the training load and the analysis of the variables that explain the physical-sports performance. The measurement and evaluation of the vertical jump have been used as standardized tests for the evaluation of physical performance and load dosing.

    The following are some of the most commonly used methods to measure vertical jump:
     twenty
    Accelerometers: Calculates the speed, force and power resulting from the measurement of acceleration (variation in speed time). This device has less precision than linear positioning meters, since they show higher average and dispersion values than direct speed measurement.
     25
    Mobile application: It consists of using the mobile device camera (smartphone) to record videos and then select the takeoff and contact images to obtain a vertical jump value through the duration of the jump. The collection of information is not instantaneous and the accuracy in the measurement depends on the subjective opinion at the time of the selection of the moments of the 30 images. The measurement is derived from the flight time and in addition the measurement depends on the execution of the user's own jump which produces an overestimation of the jump height reached if the execution is not correct.

    Contact platforms: These are mixed instruments that use a measuring system 35
    (hardware) and data management (software) to directly determine time accurately and objectively, calculate other kinematic variables and infer some kinetics during different conditions of jump capacity and some locomotion activities. It contains a contact sensor or conductive platform and a microcontroller that measures the elapsed time and a software that manages and 5 presents the measured and calculated data. Its main drawback lies in its low precision and the rapid deterioration suffered by the aforementioned sheets (ES 2344980 B1; US 5838638).

    Infrared platforms: They consist of the use of two infrared sensor barriers, separated at a certain distance, between which the subject of the study runs. The system detects possible interruptions and their duration. Its main problem remains the precision, which will depend on the number of sensors used, another drawback is that the measurement is derived from the flight time and also the measurement depends on the execution of the user's own jump which produces an overestimation of the jump height reached if the execution is not correct. Its main problem is the high price of the product, which determines a high final sale price.

    Laser platforms: It is a system for obtaining optical data, consisting of a transmitter and a receiver optical bar. Each contains infrared LEDs. These LEDs are located on the transmitter bar and communicate continuously with the LEDs located on the receiver bar. The system detects possible interruptions and their duration. This allows the measurement of flight and contact times during the execution of jumps. Starting from this fundamental database, the particularly designed software 25 allows real-time and realization. Its main problem remains the precision, which will depend on the number of sensors used, and their location that forces the subject to run through a given space. The measurement is derived from the flight time and in addition the measurement depends on the execution of the user's own jump which produces an overestimation of the jump height reached if the execution is not correct. Its main problem is the high price of the product (KR 20040099226).

    Support detection system via radio: It consists of a support detection system carried out during walking, running and jumps, which is also based 35
    in the ability of electrical conductivity to quantify contact and non-contact times. The measurement is derived from the flight time and also the variability depends on the execution of the user's own jump (ES 2237280 B1).

    All these aforementioned devices have the disadvantage of not making a direct measurement of the jump height, but that it is derived from the flight time or through devices with low measurement accuracy. This formula for calculating the height of the jump is susceptible to error in itself due to the derivative of the function and mainly, due to the execution of the user's own jump, since when using all of them the estimation of the jump from time of 10 flight, the modification of the landing technique (by not making contact with the ground with the forefoot or when falling with the knees slightly bent) modify the flight time, which results in an overestimation of the height of the jump reached.

    This error in the measurement that exists in practically all the instruments 15 designed for the measurement of the jump raises the need to devise an alternative method, that uses a technology that eliminates the deficiencies presented by the methods used at present and that allows to know in Real-time jump capacity which is the object of the present invention. To alleviate the deficiencies described above, a recent study in the field of sports training has shown that the maximum speed reached by the subject during the concentric action (ascent phase) in a jump can be used to calculate the height of the jump (Garcia -Ramos et al., 2015; J Sports Sci Med, 14 (2), 256-262). In addition, another recently published study has shown how the maximum speed reached during the jump is a more sensitive variable to detect small changes in performance than the jump height calculated from the flight time (Jimenez-Reyes, Pareja- Blanco, Rodriguez-Rosell, Marques, & Gonzalez-Badillo, 2016; J Sports Physiol Perform, 11 (2), 227-234). This contribution could be decisive for the advancement of the science of sports training since until now it has never been known what real changes have been produced by a certain training, since it was modifiable mainly by the position on the landing. Measuring the maximum speed during a jump would solve this problem, since it is a direct measurement of performance during the phase in which the subject is applying force (while the subject is in contact with the ground, prior to the flight phase of the jump). It is known that the application of force 35
    would be solely responsible for the modification of the state of motion of a body (F = m.a) in this case, the subject. Therefore, once the subject is in the air, he will not be able to apply force, so that the performance he achieves will be determined by what happened in the pre-takeoff phase. So the maximum speed control could be considered as the most advanced method 5 to monitor the performance in the vertical jump.

    In addition, the device offers greater ease and comfort in measurement, since it does not need the device to be attached to the user / athlete directly through cables or needing to use a load to measure the travel speed, 10 as already occurs , with linear positioning meters and accelerometers.


    DESCRIPTION OF THE INVENTION
     fifteen
    The proposed device has been conceived to solve the problem described above in each and every one of the aspects mentioned.

    For this, and more specifically, based on the basic structuring of a platform, platform or drawer of resistant material, the system of the invention focuses its 20 characteristics on the fact that it incorporates a radar to detect the speed at which it is move the user in a jump. Said device (radar) is connected to a data capture card, which communicates with a computer equipment, it can be both a mobile device and a device fixed to the invention provided with a touch screen, so that the radar specific software informs to the user 25 by means of visual feedback on screen and sound, through at least 1 speaker, the speed (maximum and average) reached in each jump instantaneously and the height of the jump.

    The radar will emit the waves preferably in a vertical direction with respect to the base 30 of the platform, platform or drawer, so the radar will be fixed to the platform, platform or drawer but it will be possible to modify its position if necessary.

    The material that makes up the platform, platform or drawer is a resistant material, which allows jumps to be carried out without any damage, in addition to allowing the user to make the jumps efficiently.

    The platform, platform or drawer has an opening that allows the propagation of the 5 radar waves, this area must allow optimal propagation of the waves and also be resistant to the impacts of the jumps.

    The device with all the characteristics described above allows an optimal fixation to the ground for the realization of the jumps and also due to the use of 10 light materials it allows to transport the device in a simple way, turning it into a device both fixed and portable.

    In addition, for its power supply, the device comprises a battery or accumulator of prolonged duration that allows the use of the device without the need to be connected to electric current; alternatively it will consist of a feeder composed of specific elements (cable and plug) that allow to connect to the electric current directly.
