Description

[0001] STRENGTH MEASURING TOOL FOR ARM WRESTLING Technical Field

[0002] The invention relates to a strength measuring tool developed for sports sciences, biomechanics, sports technologies, and measurement of sports performance. Specifically, the invention relates to a strength measuring tool that enables the precise measurement of wrist and arm muscle strength in the sport of arm wrestling, enabling athletes to exercise, optimizing training programs and evaluating the performance of athletes.

[0003] State of the Art

[0004] Arm wrestling is a sport in which two competitors compete on an arm-wrestling table, without any time constraints, under the control of a referee, to gain an advantage over the opponent by forcing the opponent's hand to touch the pad on the table or lowering it to the same level. In an arm-wrestling match, two competitors take the starting position by grasping the handle of the arm-wrestling table fixed with one hand to gain leverage, placing the elbow of the other arm on the elbow pad, and grasping the opponent's hand. After this stage, the referee initiates the match by issuing the "ready-go" command after making certain checks and adjustments, such as wrist, shoulder position, and finger placement, to ensure both athletes begin the match on equal footing. Athletes strive to touch or align each other's hands on the pad without engaging in foul-considered behaviors such as raising their elbows or releasing the handle. Arm wrestling is a sport with no dead heat. Arm wrestling competitions are widely held as amateur and performance sports. Modern arm wrestling can be defined as an explosive power sport that prioritizes branchspecific strength training. Because success in this sport depends on muscle group strength ratios that are critical for the bio-kinematic chains required for certain arm-wrestling techniques.

[0005] Fundamentally, muscle strength and power are essential for performing the physical activities required by daily life. Every person needs muscle strength and power to perform these physical activities. Changes in the musculoskeletal system can be linked to increases in strength and power. Increased muscle volume and development of muscle structure can lead to increased strength, and thus, improved motor skills and muscle control. The high-level motor skills and muscle control observed in athletes, in particular, can be linked to improvements in the strength and power they gain from their branch-specific athletic activities. In this context, the fundamental requirement for strength and power can be considered the foundation of most sports. An arm wrestler's primary mission is to develop the maximum capacity of a competitive movement, that is, the maximum power required in the shortest possible time.

[0006] The professional performance of today's sports has increased the expectation of efficiency. The demanding nature of performance sports is increasing, and coaches are leveraging training science to meet their athletes' development goals. The effectiveness and suitability of applied training are evaluated through specific tests and their assessments. Athletic performance improvement in arm wrestling, as well as in other sports, depends largely on the athletes' specific fitness levels. Therefore, monitoring differences in strength and power among athletes, and determining their current strength parameters is crucial for developing performance athletes and creating training plans and programs. In most sports, strength and power-building training plans are supported by weight training. This allows muscles to be trained using energy systems and movement variations appropriate for the sport branch, aiming to improve performance.

[0007] Strength training is becoming increasingly important in branches that require sporting skills. An activated muscle produces strength, but even if it does produce strength as a result of activation, it cannot be said that the muscle fibers shorten by approaching each other. According to Faulkner, in the early 20th century, researchers discovered the interaction between muscle strength and the load on the muscle, leading to muscle activations such as lengthening (eccentric), shortening (concentric), and unchanged muscle length (isometric). This led to the redefinition of muscle contraction as action and strength production. Of these, isometric contraction is a type of contraction that occurs without a change in muscle length. In fact, during isometric contractions, small differences in muscle fiber length and changes in muscle elasticity occur. The majority of the strength produced by competitors during arm wrestling occurs through isometric contractions. The level and duration of strength produced by isometric contractions can be directly linked to the contribution of performance improvement in arm wrestling (Fidan, 2020). [1] Arm wrestling involves primary (medial rotation of the upper arm, forearm and hand pronation, and wrist flexion) and secondary (arm and forearm flexion) movements using muscles such as the Pectoralis Major, Biceps Brachii, Pronator Teres, and Flexor Carpi Ulnaris. In fact, the Pectoralis Major and Flexor Carpi Ulnaris muscles serve as agonists in arm wrestling, while the Biceps Brachii and Pronator Teres muscles perform secondary functions.

[0008] The current system includes various patent / utility model applications and articles related to the subject. The present patents generally focus on strength measuring tools and various resistance mechanisms for arm wrestling training. The state-of-the-art patent application numbered " US 4,063,727" describes an arm-wrestling exercise device. It aims to increase wrist strength using a resistance arm and flexible springs. This device offers a system that can be adjusted according to the arm length and age of individual users. However, this patent does not provide a system that measures strength numerically and it merely provides resistance training. There is a need for technology that digitally measures and records strength, allowing performance to be analyzed with objective data.

[0009] The state-of-the-art patent application numbered " US 6,691,247" relates to a strength measuring tool. This patent provides a mechanism for measuring strength applied during arm wrestling. However, while this device focuses on strength measurement, it does not provide detailed analysis of how individuals apply strength in different positions. Therefore, there is a need for a technology capable of measuring both static and dynamic strength and analyzing athletes' performance at different angles.

[0010] The state-of-the-art utility model application numbered " CN202342753U" relates to an arm-wrestling trainer apparatus. It is mounted on a workbench and includes a support frame thereon. A tensile strength sensor and indicator are connected to the lower section via a spring after a hole in the workbench. The strength sensor and indicator can be used to determine current arm strength. Because people have different arm lengths, a slide track was added to accommodate these.

[0011] The state-of-the-art patent application numbered " CN101370560A" relates to an armwrestling robot that simulates a human wrist. The arm wrestling robot includes an electric motor that provides the necessary torque based on the motor control input signal calculated by the control system; a position / velocity sensor that detects the angular position and angular velocity of the motor and provides feedback to the control system regarding the angular movement; a torque sensor placed between the speed reducer and the robot arm and configured to detect a torque acting on the robot arm; and the robot arm.

[0012] Studies on strength measurement in the literature generally focus on general sports performance measurements and are not optimized for a specific sport branch, such as arm wrestling. For example, the study conducted by O’Sullivan, Harrison and Cahalan (2009) focused on general strength measuring tools [2] but did not address specific systems measuring arm and wrist strength, such as those used in arm wrestling. Furthermore, a wide variety of devices have been developed worldwide to measure static and dynamic strength. Results obtained from isometric protocols can be used as indicators of functional performance and athletic strength. Studies have shown that isometric strength training is beneficial as a complementary training method for developing many types of strength, from rapid strength to explosive strength.

[0013] Current patent applications focus on resistance training rather than strength measurement, failing to accurately measure the strength applied in arm wrestling. This makes it particularly difficult to objectively monitor athletes' training processes and accurately assess performance. Despite the abundance of research on strength development in the literature, there is a dearth of strength training studies using isometric contractions. At the same time, research on arm wrestling is limited, and there are almost no strength development tools specifically designed for arm wrestling, such as those performed with isometric contractions (Akpinar et al., 2012). [3] Many currently used methods measure general strength but are not optimized for a specific sport branch like arm wrestling. Furthermore, existing devices cannot precisely measure the strength exerted by athletes at different angles and positions, nor can they track their training processes in detail. Therefore, a system optimized specifically for arm wrestling is needed.

[0014] Due to the drawbacks described above and the inadequacy of existing solutions related to the subject, in the sport of arm wrestling, there is a need for technology that allows precise measurement of wrist and arm muscle strength, optimization of training programs and evaluation of athlete performance.

[0015] Brief Description and Objectives of the Invention

[0016] The invention relates to a strength measuring tool that meets all the aforementioned requirements, eliminates the drawbacks and disadvantages of the current system, enables precise measurement of the strength of the wrist and arm muscles in the sport of arm wrestling, optimizes training programs and evaluates the performance of athletes.

[0017] The device developed with the invention is designed to numerically measure and analyze strength in arm wrestling training. This facilitates athletes' ability to optimize their performance based on meaningful data. The apparatus developed with the invention enables comprehensive performance analysis of athletes by taking dynamic strength measurements at different angles and positions. The apparatus is capable of compensating for anthropometric differences, such as arm length. This allows for monitoring changes in strength across different positions. Furthermore, the invention's ability to measure strength exerted by athletes at various angles helps them better analyze their strengths and weaknesses, and measuring strength in different positions indicates the areas athletes should focus on during their training.

[0018] The developed apparatus can be easily set up and used in any location thanks to its portability.

[0019] With this invention, the data obtained by athletes throughout their training process can be tracked in detail. This performance tracking, combined with dynamic measurements, allows athletes to more consciously evaluate their progress.

[0020] The invention also monitors athletes' individual strength levels and positional strength differences, allowing them to develop training programs tailored to individual needs. This accelerates performance improvement and helps athletes strengthen their weaknesses. The invention provides athletes with feedback, enabling controlled exercise. By monitoring the correct and planned execution of exercises, and providing feedback, it provides the athlete with the opportunity for long-term, controlled training aimed at improving performance.

[0035] Detailed Description of the Invention

[0036] The invention relates to a strength measuring tool developed for sports sciences, biomechanics, sports technologies, and measurement of sports performance. Specifically, the invention relates to a strength measuring tool that enables the precise measurement of wrist and arm muscle strength, optimization of training programs, and evaluation of athlete performance in the sport of arm wrestling. The strength measuring tool is positioned on the table pad (1) as shown in Figure 1. The table pad (1) provides ergonomic and comfortable support when using the arm wrestling strength measuring tool. The table pad (1) ensures stable placement of the device and allows users to maintain a comfortable position during measurement. When placing users' hands or wrists on the measurement device, the table pad (1) improves their sitting or standing position, thus ensuring correct strength transfer during measurement and more accurate results. Furthermore, the table pad (1) ensures the physical placement of the device and correct body alignment of users, increasing the consistency of strength measurement and preventing potential inaccurate measurements. The table pad (1) contains an elbow pad (2) on which the athlete rests their elbow, the strength meter body (4), the strength meter adjustment post (5), the distance adjustment chain (6), the finger grip (7), and the grip handle (8). The table pad (1) is also positioned on the table frame (3).

[0037] The elbow pad (2) supports the measurement process by ensuring users position their elbows correctly and safely when using the arm-wrestling strength measuring tool. The elbow pad (2) stabilizes the elbows, ensuring correct positioning, especially in sports like arm wrestling, where strength measurements are intense and dynamic. This feature prevents the elbow from shifting to the right or left, ensuring the proper transmission of strength during measurement. Furthermore, the elbow pad (2) provides users with a sense of comfort and safety during prolonged measurement, reducing the risk of potential injury. By ensuring a comfortable elbow position, it helps achieve accurate results during training or testing. This increases the accuracy and reliability of the device.

[0038] The table frame (3) is the skeletal structure, usually made of materials such as metal or wood, that forms the basic structure of a table. The table frame (3) is the main load-bearing element that supports the table's upper section (i.e., the surface on which the components or devices will be placed) and stabilizes the table. The frame provides the rigidity and stability of the table. In the present invention, the table frame (3) is the structure that provides the platform on which the strength measuring tool is placed. This table frame (3) allows the device to be positioned accurately and remain stable and allows users to perform strength measurements safely. The durability and stability of the table frame (3) are critical to the reliability of the measurement, because it is essential for accurate strength measurements that the device does not move or shake.

[0039] The strength meter body (4) forms the central building block that ensures accurate strength measurement by holding all the device's components (such as the load cell, connection points, and adjustment mechanisms) in place. The strength meter body (4) protects the device from external factors (e.g., impact or vibration) and ensures stable operation, thus increasing measurement accuracy and reliability. It also ensures ergonomic use and ease of transport. The strength meter adjustment post (5) consists of the vertical metal rods of the strength meter body (4). The protrusions on it optimize strength measurement. Grip handles (9) of various lengths and dimensions are fixed to these protrusions. This allows training to achieve the desired strength level.

[0040] The distance adjustment chain (6) is located between the load cell and the rotatable handle grip apparatus (8) and offers adjustment according to the user's physical characteristics. Configured to effectively and accurately transmit strength, it offers user adjustability, allowing for adaptability to different strength levels. This adjustable chain (6) mechanism allows the strength meter to be used by users with different hand and wrist structures, increasing the flexibility and accuracy of measurements. The adjustable structure of the chain (6) ensures that strength is transferred directly and evenly to the load cell, optimizing measurement reliability and device functionality. This feature contributes to obtaining precise and repeatable measurement results that can be customized to individual needs for users. The finger grip (7) helps users of the arm-wrestling strength measuring tool position their hands correctly during measurement and transmit strength more effectively. The finger grip (7) allows the user to hold the device firmly and maintain the control necessary to properly measure strength. Furthermore, if it has an ergonomic design, it prevents discomfort that may occur in the wrist or fingers during prolonged use, ensuring more accurate and reliable results during measurement.

[0041] The rotatable handle grip apparatus (8) allows the user to measure strength from various positions, angles, and grips. Its rotating structure allows it to rotate in different directions and be adjusted to suit the user's needs. This allows the most efficient angle to be achieved for the arm and wrist positions during use. The strength sensor, which measures the strength exerted by the arm wrestler on the rotatable handle grip apparatus (8), is positioned here. The grip handle (9) allows users with varying finger widths, hand sizes, and wrist structures to be accommodated. This allows each user to comfortably hold the measurement device and adopt the appropriate position to accurately transmit strength. These grip handles (9) enable users to use the device safely and efficiently, increasing comfort, especially during prolonged measurements or training sessions.

[0042] The elbow fixing pad (10) stabilizes the user's elbows, ensuring correct body position (stabilization) during measurement and ensuring accurate strength transmission. It also increases user comfort and reduces discomfort during prolonged use. This feature plays a particularly important role in sports involving forceful and dynamic movements, such as arm wrestling, as elbow stabilization increases the accuracy and reliability of strength measurement.

[0043] The fall pad (11) is one of the apparatuses on the match table that indicates the defeat of the athlete (user) whose hand touches the fall pad (11). It allows both referees and spectators to clearly understand the winner. The fall pad serves as a visual indicator of defeat. This prevents any confusion during the match, and the result is determined quickly. The strength sensor, positioned on the rotatable handle grip apparatus (8) of the strength measuring tool, which measures the strength exerted by the arm wrestler on the rotatable handle grip apparatus (8), includes a data collection and analysis unit that processes data received from the strength sensor via wireless communication and converts it into digital data, analyzes athlete performance, and tracks long-term development, along with a mobile application where athletes and / or coaches can review training data and development reports. The rail mechanism allows measurements to be taken at appropriate angles, making adjustments to suit athletes' anthropometric characteristics, such as arm length, carpal, and metacarpal bone lengths.

[0044] The strength sensor is a critical element for assessing athletes' muscle strength and creating a training plan based on this data. Strength changes, such as pressure, pull or push, that occur during arm wrestling are measured by the strength sensor. Using high-precision strength sensors, the strength (in Newtons / N) applied during wrist movements is measured at regular intervals with millisecond precision. The strength sensor is capable of performing static and dynamic strength measurements.

[0045] The data collection and analysis unit converts data received from the strength sensor into digital data. These data include the instantaneous strength value, the duration of strength application, the direction of strength, and its vector components. The measured strength value, as mentioned above, is the measurement of the strength applied to the wrist during a specific time period (during training or match). The duration of strength application is the value of how long the strength is applied. The direction and vectorial components of the strength are the values measured horizontally, vertically, or angularly. In other words, they indicate the direction in which the strength is applied.

[0046] The analog data from the strength sensor is converted to digital signals using an analog-to-digital data converter (ADC) before reaching the microcontroller (software). During the conversion process in the analog-to-digital data converter (ADC), data is generally collected at a specific sampling frequency (e.g., 1000 samples per second), and the precision of the data is determined by the resolution (e.g., 12-bit or 16-bit). This process is necessary for the microcontroller to process the data. The data converted into digital data is sent to the microcontroller located in the data collection and analysis unit. The microcontroller then processes this data and converts it into a meaningful form. Various criteria are used to convert it into a meaningful form. These criteria are as follows:

[0047] Average strength: The value of the average strength applied over a specific time period is calculated.

[0048] Maximum and minimum strength values: The highest and lowest strength values achieved during arm wrestling are determined. This is important for understanding the user's strength capacity. Acceleration and rate of change of strength (dF / dt): The rate of change or acceleration of strength during the time the strength is applied is calculated. This indicates how quickly the strength is applied or increased.

[0049] Fatigue index: The fatigue index can be calculated by measuring the tendency for strength to decrease over time. This helps understand how long the user can maintain maximum performance.

[0050] Figure-2 shows an example graph showing an athlete's weekly strength measurements and fatigue rate. The graph shows the athlete's average strength, maximum strength and minimum strength measurements over a 12-week training period, and fatigue rate weekly. The graph provides a comprehensive analysis for monitoring athlete progress and comparing fatigue and strength gains.

[0051] In the graph, average strength (N) represents the athletes' average strength value for each week and allows for regular monitoring of athlete performance. While the average strength value in the first week is 200 N, this value increases steadily each week and reaches 260 N in the 12th week. This increase indicates that the athlete is adapting to the training loads and increasing his / her muscle strength. This indicates that the strength training is successful and the athlete is making steady progress. Maximum strength (N) represents the highest strength value recorded each week and reflects the highest strength level the athlete can achieve during training. The maximum strength value, which is 250 N in the first week, increases to 310 N in the 12th week. This demonstrates a steady improvement in the athlete's peak strength. The increase in maximum strength indicates that the athlete is both pushing his / her physical limits and improving his / her muscular performance. On the other hand, minimum strength (N) represents the lowest strength level recorded each week. This value is important for monitoring the athlete's fatigue level or periods of low performance during training. The minimum strength value was measured at 180 N in the first week, and this value increased each week, reaching 240 N in the 12th week. This increase in minimum strength indicates that the athlete's baseline strength level has increased and that he / she is performing better during each training session. The fatigue index (%) represents the level of fatigue experienced by the athlete based on training intensity. This rate, which is 10% in the first week, decreases to 4.5% in the 12th week. The decrease in the fatigue index indicates that the athlete is adapting to the training and experiencing less fatigue. This indicates that the athlete's endurance capacity has increased and that signs of fatigue during strength application have decreased. Average strength, maximum strength, minimum strength, and fatigue index data are also shown in the table below.

[0052] Week Average Strength Maximum Minimum Strength Fatigue Index (%) (N) Strength (N) (N)

[0053] 1 200 250 180 10.0

[0054] 2 210 260 190 9.5

[0055] 3 215 265 195 9.0

[0056] 4 220 270 200 8.5

[0057] 5 225 275 205 8.0

[0058] 6 230 280 210 7.5

[0059] 7 235 285 215 7.0

[0060] 8 240 290 220 6.5

[0061] 9 245 295 225 6.0

[0062] 10 250 300 230 5.5

[0063] 11 255 305 235 5.0

[0064] 12 260 310 240 4.5

[0065]

[0066] Table 1: Average Strength, Maximum Strength, Minimum Strength, and Fatigue Index Data

[0067] The values in the table indicate that the athlete consistently improved his / her strength performance each week, with maximum, average, and minimum strength values increasing steadily. At the same time, the decrease in the fatigue index indicates that the athlete experienced less fatigue despite the increase in strength levels and that his / her endurance level increased. This demonstrates that the training program was effective and efficient for the athlete.

[0068] To convert the data into a meaningful form, the microcontroller generates meaningful statistical data using the aforementioned data. These data are as follows:

[0069] Strength Profile Chart: This is a graphical output showing strength changes over time. This allows for analysis of when maximum strength is reached and how strength increases / decreases during arm wrestling.

[0070] Performance Score: An arm-wrestling performance score can be generated using all measurements. This score summarizes the user's performance by considering both the magnitude and duration of the strength. Strength-Balance Ratio: A balance ratio can be calculated to compare users' right and left arm-wrestling strength.

[0071] In all these stages, the microcontroller processes the data and presents it to the user in real time on a screen or via a mobile application. Real-time strength changes and performance analyses allow users to instantly evaluate themselves. These data can also be subjected to graphical and statistical analysis to monitor athletes' progress.

[0072] Storing measurement data in the cloud allows athletes and coaches to access the data from anywhere. This system allows for secure data storage and sharing.

[0073] Due to the varying heights and wrist structures of athletes, the rotatable handle grip apparatus (8) and elbow pad (2) are adjustable. To ensure a grip appropriate for athletes' hand and wrist structures, the length and width of the rotatable handle grip apparatus (8) are adjustable. This adjustment ensures proper grip during arm wrestling and helps prevent excessive strain or discomfort. This allows for an optimal grip for athletes with small or large hands.

[0074] This feature also makes the device universally applicable and ensures accurate measurements. The ergonomic and adjustable rotatable handle grip apparatus (8) provides optimized strength measurement based on wrist position. The elbow pad (2) stabilizes athletes' wrist position, helping to achieve more accurate results.

[0075] Furthermore, the surface of the rotatable handle grip apparatus (8) is made of a non-slip and comfortable material. This surface provides a safe grip, even when athletes' hands are sweaty. Its adjustability allows for increased or decreased grip resistance to meet different strength levels.

[0076] Because athletes' wrist size, angle and endurance levels can vary, the wrist support mechanism features adjustable height and angle. The wrist support maintains athletes' natural wrist position, preventing overload and providing a safe measurement environment. This allows athletes to apply maximum strength without straining their wrists. The wrist support mechanism is made of material resistant to the stresses that may occur during strength application. It maintains its fixed position, providing athletes with extra support and minimizing stress on the wrist area.

[0077] As mentioned, the handles and wrist support mechanism are equipped with a gradual adjustment system that allows users to make fine adjustments down to the centimeter level. This system allows each athlete to make fine adjustments tailored to their physical characteristics.

[0078] A software system has been developed to instantly track measurement data and enable long-term performance analysis. This allows athletes and coaches to review training data and progress reports via the mobile application. Data is instantly transferred to the mobile application via wired or wireless communication (Bluetooth, Wi-Fi). The user-friendly interface allows athletes to easily review their data. Performance analyses are also presented graphically and feedback is provided. The mobile application can also create training programs and track progress. Thanks to the device's digital integration, real-time feedback can be provided during training. Users can monitor their performance in real time during training and adjust as needed.

[0079] Furthermore, an artificial intelligence algorithm has been developed to analyze performance data. This system can predict users' strength development and provide personalized training recommendations. Integrations that allow users to share their progress and achievements on social media platforms can be used to create a community and boost user motivation. The mobile application (5) offers training modules and video content, helping users learn proper techniques. This, in turn, increases the effectiveness of training sessions. Integrating the strength measuring tool with other sports equipment and health monitoring devices provides a more comprehensive performance analysis.

[0080] The strength measuring tool's portability allows athletes to take it wherever they train. This feature makes it suitable for use in both training and competitive environments. Made of lightweight materials, the device has a modular structure and can be easily assembled and disassembled. This allows the strength measuring tool to be conveniently transported to the athletes' areas of use.

[0081] The strength measuring tool allows coaches to regularly measure athletes' strength levels. This allows athletes' progress to be closely monitored and training programs to be made more efficient. This invention allows athletes to measure their strength before competition to determine which techniques and strategies will be most effective. Thus, it allows for better preparation against their opponents. Furthermore, the invention allows for strength analysis in clinical research on athlete health, allowing for more accurate assessment of injury risks. The strength measuring tool is also an important tool for determining the abilities of young athletes during their developmental stages and for developing personalized training programs.
