Description

Technical Field

[0001] This invention relates to the field of sports physical fitness testing technology, specifically to the rugby-specific test BeepTackle. Background Technology

[0002] In the field of athlete fitness assessment, maximum oxygen uptake (VO2 max) is a core physiological indicator for measuring an individual's aerobic endurance. Current technologies typically employ multi-stage fitness tests (e.g., the Beep Test) to measure this indicator. These tests assess the cardiopulmonary limits by controlling subjects to perform shuttle runs at a preset pace with progressively increasing loads.

[0003] However, for contact sports like rugby, an athlete's physical performance is not determined solely by running ability. A vigorous rugby match often involves hundreds of sprints combined with high-intensity physical contact (such as tackling). Existing running test models are primarily designed to assess sustained aerobic capacity, thus failing to incorporate the significant physiological load from these intermittent, high-intensity specific movements (such as tackling) into the evaluation system. This results in a significant difference between the test scenario and the demands of real-world matches.

[0004] Therefore, relying solely on assessment results obtained from traditional running tests is insufficient to comprehensively and accurately reflect a rugby player's specific endurance on the actual field, especially their ability to maintain performance after repeated high-intensity collisions. This limitation in assessment methods means that coaches lack sufficient objective and specific data support when developing training plans, selecting athletes, or evaluating their competitive state, thus creating a technical problem that urgently needs to be addressed in existing technologies.

[0005] Therefore, this invention proposes a rugby-specific detection method called BeepTackle to address the shortcomings of existing technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides the BeepTackle rugby-specific testing method, which solves the problem that indirect physical fitness tests cannot quantify specific combat loads, leading to a disconnect between assessment results and athletes' actual combat abilities.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] The first aspect of this invention provides a rugby-specific detection tool called BeepTackle.

[0009] The device includes: an impact intensity acquisition unit, an audio playback unit, a storage unit, an input unit, an output unit, and a processing unit. The processing unit is electrically connected to the impact intensity acquisition unit, the audio playback unit, the storage unit, the input unit, and the output unit.

[0010] The processing unit runs a preset test program stored in the storage unit to achieve the following functions:

[0011] The subject's weight W is received through the input unit.

[0012] Secondly, the processing unit controls the audio playback unit to play audio signals with a preset rhythm to guide the subject to perform a cyclical test that includes running and impact actions, and determines the final level L reached by the subject when the test ends, based on the test progress.

[0013] The processing unit calculates the maximum oxygen uptake based on the collected and received data.

[0014] In one technical solution of the present invention, the specific process of the processing unit calculating the maximum oxygen uptake is as follows:

[0015] The intermediate variables are calculated. The processing unit calculates the final speed v, representing the subject's running ability, based on the initial speed and speed increments preset in the storage unit, and in conjunction with the determined final level L. final .

[0016] Simultaneously, the processing unit calculates the level completion rate d using the determined final level L and its rounded-down integer portion. This level completion rate d characterizes the subject's degree of completion in the final test level.

[0017] Subsequently, based on the level completion rate d and the preset fatigue accumulation coefficient, the standardized impact load coefficient r is calculated. This standardized impact load coefficient r mathematically correlates discrete impact actions with the continuous process of the test, in order to quantify the physiological load generated by the grappling action under progressive fatigue.

[0018] After calculating the aforementioned intermediate variables, the processing unit applies a specific maximum oxygen uptake assessment model and integrates the final velocity v. fimal The maximum oxygen uptake (VO2max) is calculated using the standardized impact load coefficient r and the input subject weight W.

[0019] The specific maximum oxygen uptake assessment model is as follows:

[0020] VO2max=(k v ×v final )+C+kimpact ×r×W 0.75 -k penalty ×(1-r);

[0021] In the formula, k v C, k impact and k penalty The preset model coefficients are stored in the storage unit.

[0022] In another embodiment of the present invention, the processing unit is further configured to determine a test termination condition. The test termination condition includes:

[0023] The subject fails to complete the running cycle within the specified time of the audio signal twice in a row, or the subject's impact intensity is lower than the preset benchmark threshold twice in a row.

[0024] In another embodiment of the present invention, the impact intensity acquisition unit, the storage unit, and the processing unit are disposed inside the housing. The input unit consists of a setting key located on the top of the housing and volume keys located on both sides of the front of the housing. The output unit is a screen located on the middle side of the front of the housing. The audio playback unit consists of speakers located on the right and lower sides of the housing and a speaker located on the left side of the housing. A charging port is provided on the middle side of the top of the housing.

[0025] To improve the ease of installation and stability of the device, a back plate groove is provided at the rear of the housing. The device also includes a quick-release plate mechanism disposed inside the back plate groove and a locking mechanism for locking the quick-release plate mechanism. Two slots are provided at the bottom of the back plate groove, and two plates are provided at the bottom of the quick-release plate mechanism, which engage with the slots. Two plates are provided on the top front side of the quick-release plate mechanism, and a circular hole is provided at the top of each plate. The locking mechanism includes a pressable lever that detachably engages with the circular hole, thereby locking the quick-release plate mechanism within the back plate groove.

[0026] A second aspect of the present invention provides a rugby-specific BeepTackle detection method, which is applied to the aforementioned rugby-specific BeepTackle detection device.

[0027] The method includes the following steps:

[0028] S1. The subject's weight is obtained through the input unit, and the audio signal of the initial rhythm is played through the audio playback unit;

[0029] S2. Guide the subject to perform a cyclical test including running and impact actions according to the rhythm of the audio signal, and have the impact intensity acquisition unit collect the impact intensity data of each impact.

[0030] S3. After the subject triggers the preset test termination condition, record the final level reached.

[0031] S4. The processing unit calculates the maximum oxygen uptake based on the acquired body weight, final level, and impact intensity data.

[0032] This invention provides a rugby-specific detection method called BeepTackle. It has the following beneficial effects:

[0033] 1. This invention incorporates a tackling load calculation component related to the subject's metabolic weight and standardized impact load coefficient into the VO2 max assessment model, thereby integrating the metabolic consumption generated by specific impact actions in rugby into the assessment system. This ensures that the final assessment result is no longer limited to simple running aerobic capacity but integrates the physiological load of specific combat, thus more accurately reflecting the athlete's comprehensive physical fitness level under near-real-competition conditions and enhancing the specificity and practical reference value of the assessment results.

[0034] 2. This invention transforms discrete, difficult-to-compare impact actions during testing into a continuous mathematical variable closely related to the final test level by constructing a standardized impact load coefficient. This coefficient not only scientifically addresses the subject's performance in incomplete levels but also quantifies the cumulative effect of fatigue, resulting in high consistency and comparability between different test results. This solves the problem of traditional methods' difficulty in standardizing the assessment of intermittent adversarial performance.

[0035] 3. The housing of the device of the present invention, through the setting of a back plate groove and the mechanical structure of the locking mechanism and the quick-release plate mechanism, achieves a stable and quick-release fixing method. This structure allows the device to be quickly installed on or removed from the athlete's equipment, greatly simplifying the pre-test preparation process, reducing equipment debugging time, and thus improving the overall testing efficiency and ease of operation in team or field environments.

[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] See attached document Figure 1 -Appendix Figure 3 , Figure 1 This is a schematic diagram of a test site setup according to an embodiment of the present invention. Figure 2 This is a flowchart of a specific testing method according to an embodiment of the present invention. Figure 3 This is a flowchart for calculating maximum oxygen uptake according to an embodiment of the present invention. The present invention provides a rugby-specific BeepTackle detection device, which functionally includes: an impact intensity acquisition unit, an audio playback unit, a storage unit, an input unit, an output unit, and a processing unit.

[0050] In terms of hardware, the impact intensity acquisition unit can be a sound level meter or decibel meter, used to collect impact intensity data generated by each impact action of the subject during the test. The audio playback unit is a speaker or sound generator, used to play audio signals with a preset rhythm to control the subject's testing process. The input and output units can be integrated into a touch screen, or consist of physical buttons and a display screen respectively. The storage unit is a non-volatile storage medium, such as flash memory. The processing unit can be a microcontroller (MCU) or an embedded system processor. All units are electrically connected through an internal bus or circuit board and are coordinated by the processing unit.

[0051] The storage unit contains a preset test program and a set of model coefficients. The model coefficients include: initial velocity v. initial The velocity increment Δv per stage, and the velocity-oxygen uptake conversion coefficient k. v Basal metabolic calibration constant CC, impact-oxygen uptake conversion factor k impact Efficiency adjustment coefficient k penalty and fatigue accumulation coefficient k fatigue .

[0052] The processing unit is configured to execute the test procedure to specifically assess the subject's maximum oxygen uptake. In a complete test and calculation process, the processing unit first receives and stores the subject's weight information (W) through the input unit. After the test begins, the processing unit controls the audio playback unit to play the audio at a preset initial speed (v). initial The audio signal was played at each velocity increment (Δv) to guide the subjects in a certain direction. Figure 1 The test site shown is used for a cyclical test involving running and impact movements.

[0053] During the test, the impact intensity acquisition unit collects impact intensity data for each impact in real time and transmits it to the processing unit. The processing unit determines the test to be terminated based on preset termination conditions, such as the subject failing to keep up with the rhythm of the audio signal twice consecutively or the impact intensity failing to meet the standard twice consecutively, and records the final level (L) at the time of test termination.

[0054] After the test is terminated, the processing unit executes the core algorithm to calculate the maximum oxygen uptake (VO2max). This calculation process first obtains two key intermediate variables: the final velocity (v... final ) and standardized impact load factor (r). The final velocity (v) final The formula for calculating ) is:

[0055] v final =v initial +Δv×(L-1);

[0056] The calculation of the standardized impact load factor (r) consists of two steps. First, the level completion rate (d) is calculated:

[0057]

[0058] In the formula, This involves rounding down the final level L. Then, the standardized impact load factor (r) is calculated based on the level completion rate (d):

[0059] r=d+k fatigue ×(1-d);

[0060] In obtaining the final velocity (v) initial After calculating the standardized impact load coefficient (r), the processing unit invokes a specialized VO2max assessment model, integrating the aforementioned variables and the pre-input subject weight (W), to calculate the final VO2max. The processing unit then displays the final VO2max value and other relevant test data through the output unit.

[0061] The method includes the following steps:

[0062] S1. The subject's weight is obtained through the input unit, and the audio signal of the initial rhythm is played through the audio playback unit;

[0063] S2. Guide the subject to perform a cyclical test including running and impact actions according to the rhythm of the audio signal, and have the impact intensity acquisition unit collect the impact intensity data of each impact.

[0064] S3. After the subject triggers the preset test termination condition, record the final level reached.

[0065] S4. The processing unit calculates the maximum oxygen uptake based on the acquired body weight, final level, and impact intensity data.

[0066] See attached document Figure 4 To be continued Figure 11 , attached Figure 4 This is a schematic diagram of a device structure according to an embodiment of the present invention, with appended figures. Figure 5 This is a left-side view of the device, with appendix. Figure 6 This is a right-side view of the device, with appendix. Figure 7 This is a rear view of the device, attached.

Figure 10 This is a schematic diagram of the clamping structure in the device, attached. Figure 11This is a schematic diagram of the strap-type structure in the device.

[0067] See attached document Figure 4 This embodiment provides a rugby-specific BeepTackle detection device, the main hardware of which is a housing 1. The impact intensity acquisition unit, storage unit, and processing unit are all located inside the housing 1. A screen 7 serving as an output unit is located on the front center side of the housing 1. The input unit includes a setting button 6 located on the top of the housing 1 and volume buttons 3 located on both sides of the screen 7. The audio playback unit consists of three parts: a speaker 2 located on the left side of the housing 1, and speakers 8 located on the right and lower sides of the housing 1. A charging port 4 for power supply or charging is located on the top center side of the housing 1.

[0068] See attached document Figure 8 and attached Figure 9 To facilitate quick installation and disassembly of the device, the rear of the housing 1 is integrally formed or has a back plate groove 11. Two slots 111 are equidistantly spaced at the bottom of the back plate groove 11, and two slots 112 are equidistantly spaced at the top inner side. A latching groove 10 is provided at the top corner of the back plate groove 11 to facilitate the insertion of fingers or tools. A locking mechanism 5 is provided at the top of the housing 1, and to facilitate the installation and movement of the locking mechanism 5, a spring groove 113 and a sliding groove 114 communicating with the spring groove 113 are provided at corresponding positions on the top of the housing 1.

[0069] See attached document Figure 9 The structure of the locking mechanism 5 is described in detail below. The locking mechanism 5 includes an operation button 51. The bottom of the button 51 is connected to the top of an L-shaped rod 52. The short end of the button 51 is integrally formed or fixedly connected to a locking rod 54, the extension direction of which is parallel to the long end direction of the L-shaped rod 52. A limiting plate 55 is connected to the middle of the L-shaped rod 52. In the assembled state, the rod body of the L-shaped rod 52 is accommodated in the sliding groove 114, and the limiting plate 55 and the spring 53 are accommodated in the spring groove 113. One end of the spring 53 abuts against the top inner wall of the spring groove 113, and the other end abuts against the upper surface of the limiting plate 55, providing the locking mechanism 5 with a restoring force along the axial direction of the L-shaped rod 52.

[0070] See attached document Figure 8This embodiment also provides a quick-release plate mechanism 9 that can cooperate with the housing 1. Two locking plates 92 are equidistantly arranged at the bottom of the quick-release plate mechanism 9, the shape and position of which match the locking slot 111. Two locking plates 93 are arranged on the top front side of the quick-release plate mechanism 9, the shape and position of which match the locking slot 112. Each locking plate 93 has a round hole at its top. At the rear of the quick-release plate mechanism 9, multiple magnetic rings 91 are equidistantly arranged for adsorbing the device onto a metal surface. As an alternative, the rear of the quick-release plate mechanism 9 can also be configured as a clamping structure or a strapping structure to adapt to different fixing requirements, as shown in the attached figure. Figure 10 -Appendix Figure 11 .

[0071] When installing the quick-release plate mechanism 9 onto the housing 1, firstly, insert the first locking plate 92 into and lock it inside the first locking slot 111. Then, by pressing the button 51, the button 51 causes the L-shaped rod 52 and the locking rod 54 to move downward under the pressure of the spring (53). At this time, push the quick-release plate mechanism 9 into the back plate groove 11, so that the second locking plate 93 enters the position of the second locking slot 112. Release the button 51, and under the restoring force of the spring 53, the locking rod 54 moves upward and passes through the round hole at the top of the second locking plate 93, thereby achieving a reliable lock of the quick-release plate mechanism 9 onto the housing 1. The disassembly process is the reverse.

[0072] See attached document Figure 1 -Appendix Figure 3 This embodiment details the method and steps for conducting a complete rugby-specific test using the aforementioned BeepTackle rugby-specific testing device.

[0073] First, the test preparation phase is conducted. For the test site setup, two parallel lines 20 meters apart are marked on a flat surface, serving as the starting and ending lines. The impact point is set 4 meters before one line, i.e., 16 meters from the other line, and a standardized impact pad is placed there. The device of this invention is secured to a suitable position on the subject's torso or shoulder via its quick-release plate mechanism 9, or fixed to a tripod near the impact point, ensuring that its impact intensity acquisition unit can effectively collect the acoustic or vibration signals generated by the impact, for example, by setting it 1 meter away from the impact point. Before the test begins, the operator inputs the subject's weight (W) information into the device via the input unit, and the device's storage unit stores this data.

[0074] Next, the test execution and data acquisition phase begins. The operator starts the test program using the setting key 6. The processing unit controls the audio playback unit to begin playing the first-level audio signal. The initial velocity (v) of this audio signal... final The speed was set at 8.5 km / h. After hearing the first "beep" signal, the participant started running from the starting line towards the finish line. Upon reaching the impact point at 16 meters, the participant was required to perform a tackle or impact action in accordance with rugby rules, striking the impact pad, and then continue running, crossing the finish line at 20 meters before the next "beep" signal. Afterward, the participant turned around and ran back to the starting line from the finish line after the next "beep" signal. This constituted one complete running cycle.

[0075] During this process, the impact intensity acquisition unit collects corresponding impact intensity data each time an impact occurs and transmits the data to the processing unit. The processing unit compares the collected impact intensity with a preset reference threshold stored in the storage unit. The reference threshold is set to an intensity value that represents a valid impact, for example, an intensity equivalent to a 60 dB sound pressure level. The processing unit uses this to determine whether each impact is a valid impact and can count the valid impacts.

[0076] Each level of the test lasts approximately 62 seconds. After each level, the audio playback unit plays a preset cue tone, such as three consecutive rapid "beep" sounds, to alert the subject that the speed will increase in the next level. Subsequently, the processing unit controls the rhythm of the audio signal to accelerate, increasing the speed by an increment (Δv, 0.5 km / h in this embodiment), and the test proceeds to the next level. The subject repeats the above cycle of running and impact until they can no longer continue.

[0077] Finally, the test terminates. The processing unit continuously monitors two termination conditions during the test: first, whether the subject fails to complete the 20-meter run and cross the corresponding finish line twice consecutively before the designated "beep" signal sounds; second, whether the impact intensity data generated by two consecutive impacts is lower than a preset benchmark threshold. When either termination condition is met, the processing unit determines the test is over and automatically records and stores the last level reached by the subject before the test termination as their final level (L). This final level (L) can be a decimal value, where the integer part represents the number of complete levels, and the decimal part represents the ratio of the number of runs completed in the last incomplete level to the total number of runs in that level.

[0078] This embodiment details how the processing unit calculates the subject's maximum oxygen uptake (VO2max) based on the collected and recorded data after the test, using a core algorithm. The core of this algorithm lies in integrating a traditional running metabolic model with a rugby-specific impact load model.

[0079] After the test is terminated and the final level (L) and subject weight (W) are obtained, the processing unit first performs a series of calculations on key intermediate variables.

[0080] The first step is to calculate the final velocity (v). final This variable represents the subject's running ability level when reaching their limit. The processing unit retrieves the initial velocity v stored in the storage unit. final (e.g., 8.5 km / h) and the speed increment per step Δv (e.g., 0.5 km / h) are calculated using the following formula:

[0081] v final =v initial +Δv×(L-1);

[0082] In the formula, L is the final level recorded when the test ends.

[0083] The second step is to calculate the standardized impact load factor (r). The purpose is to mathematically correlate and quantify the discrete impact actions with the fatigue level of the subject under extreme conditions. This calculation process is further divided into two sub-steps:

[0084] First, calculate the level completion rate (d). This value reflects the subject's performance in the last level not completed. The calculation formula is:

[0085]

[0086] In the formula, This is the floor function of rounding down the final level L. When the subject has completed exactly one integer level... At this point, d = 1. When the subject terminates midway through a certain level... At this time 0 <d<1。

[0087] Subsequently, a standardized impact load factor (r) is calculated based on the level completion rate (d). This calculation incorporates a fatigue accumulation factor k pre-defined in the storage cell. fatigue (For example, 2.5). This factor is used to amplify the additional physiological load caused by accumulated fatigue in the incomplete level. The calculation formula is:

[0088] r=d+k fatigue ×(1-d);

[0089] This formula defines a standardized load unit when d = 1 and r = 1. When d < 1 and r > 1, it represents the relative load increase due to fatigue.

[0090] After calculating the aforementioned intermediate variables, the processing unit invokes a specific VO2 max assessment model, which integrates aerobic running, basal metabolism, and specific impact load. The processing unit retrieves the preset speed-VO2 max conversion coefficient k from the storage unit. v (e.g., 3.46), basal metabolic calibration constant C (e.g., 11.3), impact-oxygen uptake conversion factor k impact (e.g., 0.042) and efficiency adjustment coefficient k penalty (For example, 1.8), the final VO2max is calculated using the following formula:

[0091] VO2max=(k v ×v final )+C+k impact ×r×W 0.75 -k penalty ×(1-r);

[0092] In this model, the first part (k) v ×v final The first part represents the core oxygen uptake produced by aerobic running. The second part, C, is a calibration constant used to compensate for basal metabolic rate and other metabolic activities at rest. The third part, k... impact ×r×W 0.75 This is the dedicated load portion, of which W 0.75 This is the subject's metabolic weight based on metabolic calibration theory. This term correlates the impact load (represented by r) with the subject's individual body size (represented by W) to calculate the additional oxygen uptake required during the impact action. Part Four -k penalty ×(1-r) is an efficiency adjustment term used to dynamically fine-tune the situation where the entire level is not completed.

[0093] Finally, the calculated VO2max value will be displayed through the output unit, providing coaches and athletes with a comprehensive evaluation index that combines aerobic endurance and specific competitive ability.

[0094] To further clarify how the device and method described in this invention work together, a specific application example will be used below to provide a detailed explanation of the entire process from the start of the test to the calculation of the final result.

[0095] In this example, it is assumed that a subject weighing 85 kg is tested using the BeepTackle rugby-specific testing device described in this invention. The device's storage unit has the following model coefficients preset:

[0096] Initial velocity vfinal The speed is 8.5 km / h, the speed increment per stage Δv is 0.5 km / h, and the fatigue accumulation coefficient k fatigue The velocity-oxygen uptake conversion factor k is 2.5. v The value is 3.46, the basal metabolic calibration constant C is 11.3, and the impact-oxygen uptake conversion factor k is... impact The value is 0.042, and the efficiency adjustment coefficient k penalty It is 1.8.

[0097] First, the test operator inputs the subject's weight information (W=85kg) into the device through the input unit.

[0098] Subsequently, the test was conducted according to the testing method. The subject underwent a cyclical test of running and impact under the guidance of an audio signal until a termination condition was triggered. Assuming the subject ultimately completed a test level of 11.3, the processing unit recorded this final level (L = 11.3).

[0099] After the test is completed, the processing unit automatically executes the core algorithm.

[0100] The first step is to calculate the final velocity (v). final ):

[0101] v final =8.5+0.5×(11.3-1)=8.5+5.15=13.65km / h;

[0102] The second step is to calculate the standardized impact load factor (r). First, calculate the level completion rate (d):

[0103]

[0104] Then, the standardized impact load factor (r) is calculated based on the level completion rate (d):

[0105] r=0.973+2.5×(1-0.973)=0.973+0.0675=1.0405;

[0106] The third step is to calculate VO2max using a specific VO2max assessment model. First, the subject's metabolic weight (W) is calculated. 0.75 ):

[0107] W 0.75 =85 0.75 ≈28.16;

[0108] Then substitute all the calculated intermediate variables and preset coefficients into the complete formula:

[0109] VO2max=(3.46×13.65)+11.3+(0.042×1.0405×28.16)-(1.8×

[0110] (1-1.0405))=47.239+11.3+1.231-(1.8×-0.0405)=47.239+

[0111] 11.3+1.231+0.0729≈59.84ml / min / kg;

[0112] Finally, the calculated maximum oxygen uptake (59.84 ml / min / kg), along with the final level (level 11.3) and other test data, are displayed on the screen 7 of the output unit, providing the user with a clear and quantitative evaluation report.

[0113] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
