Description

An Interactive Sports Training Assessment Method and System Technical Field

[0001] This invention relates to the field of sports training assessment technology, and in particular to an interactive sports training assessment method and system. Background Technology

[0002] In the field of sports training, scientific and accurate training assessment is crucial for improving athletes' training effectiveness and competitive level. Traditional sports training assessment mainly relies on coaches' experience and observation and simple manual recording. This method is highly subjective, inefficient, and makes it difficult to conduct a comprehensive and accurate analysis of athletes' training data.

[0003] With the development of sensor and information technologies, some training and evaluation systems based on data collection and analysis have gradually emerged, enabling real-time monitoring and processing of athletes' exercise data. However, most existing systems only perform simple analysis on single data indicators, lacking comprehensive consideration of multiple key indicators and interactive training feedback mechanisms, and thus failing to provide athletes with personalized and precise training guidance. Summary of the Invention

[0004] The technical problem to be solved by this invention is that the existing technology has the disadvantages of lacking comprehensive evaluation, lacking dynamic adjustment mechanism, and inaccurate evaluation results. To this end, we propose an interactive sports training evaluation method and system.

[0005] The technical solution mainly consists of: an interactive sports training assessment method, the specific implementation steps of which include:

[0006] Step 1: Use the data acquisition module to collect real-time data on the athlete's physical condition, stride length, cadence, and center of gravity shift.

[0007] Step II: Using the data processing module, first perform initial settings and averaging on the body condition data, stride data, cadence data, and center of gravity shift data respectively;

[0008] Step III: Based on the initial settings and the results of averaging, the data processing module is used to calculate and output the stride score BH, the overall movement quality score ZT, and the new ideal stride LB in sequence. new ;

[0009] Step IIII: Using the results feedback and adjustment module, adjust the new ideal stride length (LB). new The results are compared with the ideal stride length (LB) obtained from the stride length data, and the correction is evaluated. The new ideal stride length (LB) is then replaced with the new ideal stride length (LB) in the next training session. new ;

[0010] Step IIIII: Iterate through Step I to Step IIII until a new ideal stride LB is achieved. new It equals the ideal stride length LB.

[0011] Preferably, the formula for calculating the stride score BH based on step III is as follows:

[0012] ;

[0013] in:

[0014] BH represents stride score;

[0015] SB stands for actual stride length. SB reflects the average number of meters taken by an athlete during running, which is the average of all steps taken and the data processed by the athlete.

[0016] LB is the ideal stride length, which reflects the ideal average distance that an athlete sets based on physical condition data and their actual training status.

[0017] When setting the ideal stride length (LB) initially, the body condition data is height, and the specific calculation formula is LB = G × k;

[0018] G represents the athlete's height in meters;

[0019] k is a proportionality coefficient, and the value of k ranges from {0.4 to 0.6};

[0020] If the actual stride length SB is large, it will be close to 0.6;

[0021] If the actual stride length SB is small, it will be close to 0.4.

[0022] Preferably, the formula for calculating the overall motion quality score ZT based on step III is as follows:

[0023] ;

[0024] in:

[0025] ZT represents the overall quality score of the movement.

[0026] SP stands for actual cadence. SP reflects the average number of steps per minute that an athlete actually takes during running, as measured and calculated.

[0027] LP is the ideal stride frequency. LP is calculated based on the athlete's ideal stride length LB and training goals. The specific calculation formula is LP=v / LB, where v is the target speed and is the training goal of meters per minute.

[0028] SY is the body center of gravity offset distance. SY reflects the average offset distance of the body center of gravity in the horizontal direction that is actually measured and calculated during the running process, i.e., the center of gravity offset data.

[0029] LY is the ideal center of gravity offset distance, which is set based on the offset degree of different athletes in history.

[0030] Preferably, the new ideal stride length LB is determined based on step III. new The calculation formula is as follows:

[0031] ;

[0032] in:

[0033] LB new For a new ideal stride;

[0034] And the new ideal stride LB new It will be used as a replacement correction value for the ideal stride length (LB) for training, correction, and interaction with athletes.

[0035] Preferably, based on the new ideal stride LB new The corrective assessment of the ideal stride length (LB) is as follows:

[0036] If the new ideal stride LB new If the stride length (LB) equals the ideal stride length, it reflects that the athlete has completed training corrections.

[0037] If the new ideal stride LB new If the stride length (LB) is not equal to the ideal stride length, it reflects that the athlete has not completed the training correction.

[0038] The technical solution mainly consists of: an interactive sports training assessment system, including a data acquisition module, a data processing module, and a result feedback and adjustment module;

[0039] The data acquisition module is responsible for collecting athletes' physical condition data, stride length data, stride frequency data, and center of gravity shift data in real time.

[0040] The data processing module is responsible for calculating and processing body condition data, stride data, cadence data, and center of gravity shift data, and based on the processing results, sequentially calculates and outputs the stride score BH, the overall movement quality score ZT, and the new ideal stride LB. new ;

[0041] The results feedback and adjustment module is responsible for displaying the corrective assessment results in the form of charts and numbers.

[0042] Preferably, the data acquisition module uses a sensor device;

[0043] The equipment used by the data processing module includes a data processing center;

[0044] The device used in the result feedback and adjustment module includes a display device.

[0045] The technical effects and advantages of this invention are as follows:

[0046] In this invention, firstly, the stride score BH is calculated, comprehensively considering the deviation between the actual stride length SB and the ideal stride length LB, thus quantifying this important indicator. Then, the stride score BH is combined with the ratio of the actual stride frequency SP to the ideal stride frequency LP to obtain a comprehensive stride length and frequency score. Furthermore, the important factor of body center of gravity offset distance is introduced, and the comprehensive stride length and frequency score is multiplied by the body center of gravity offset ratio to obtain the overall movement quality score ZT. This calculation compensates for the shortcomings of existing technologies in body center of gravity assessment, making the evaluation results more comprehensive and accurate, and more effectively identifying problems in the athlete's running movements. Finally, based on the overall movement quality score ZT, a new ideal stride length LB is calculated using an optimized cyclic influence formula. new This mechanism enables dynamic adjustment of training parameters, allowing for timely optimization of the ideal stride length (LB) based on the athlete's real-time performance and training results, making training programs more targeted and adaptable.

[0047] In addition, the system provides athletes with targeted training suggestions and corrective assessments based on their scores. Athletes can make real-time adjustments based on this guidance. The system continuously monitors and evaluates training effectiveness, forming an interactive training process. This interactive training method makes up for the lack of real-time feedback and dynamic adjustment in existing technologies, and can significantly improve training efficiency and effectiveness.

[0049] Figure 2 is a schematic diagram of the overall structure of this sports training assessment system. Detailed Implementation

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0051] Referring to Figures 1 and 2, the present invention provides a technical solution: an interactive sports training assessment method, the specific implementation steps of which include:

[0052] Step 1: Use the data acquisition module to collect real-time data on the athlete's physical condition, stride length, cadence, and center of gravity shift.

[0053] Step II: Using the data processing module, first perform initial settings and averaging on the body condition data, stride data, cadence data, and center of gravity shift data respectively;

[0054] Step III: Based on the initial settings and the results of averaging, the data processing module is used to calculate and output the stride score BH, the overall movement quality score ZT, and the new ideal stride LB in sequence. new ;

[0055] Step IIII: Using the results feedback and adjustment module, adjust the new ideal stride length (LB). new The results are compared with the ideal stride length (LB) obtained from the stride length data, and the correction is evaluated. The new ideal stride length (LB) is then replaced with the new ideal stride length (LB) in the next training session. new ;

[0056] Step IIIII: Iterate through Step I to Step IIII until a new ideal stride LB is achieved. new It equals the ideal stride length LB.

[0057] Referring to Figure 1, the present invention also provides a technical solution: an interactive sports training assessment system, including a data acquisition module, a data processing module, and a result feedback and adjustment module;

[0058] The data acquisition module is responsible for collecting athletes' physical condition data, stride data, cadence data, and center of gravity shift data in real time.

[0059] The data processing module is responsible for calculating and processing body condition data, stride length data, cadence data, and center of gravity shift data. Based on the processing results, it sequentially calculates and outputs the stride length score (BH), the overall movement quality score (ZT), and the new ideal stride length (LB). new ;

[0060] The Results Feedback and Adjustment module is responsible for displaying the corrective assessment results in charts and numbers.

[0061] The data acquisition module uses sensor devices;

[0062] The equipment used in the data processing module includes a data processing center;

[0063] The devices used in the results feedback and adjustment module include display devices.

[0064] In this embodiment, the iterative execution of steps I to IIII by the data acquisition module, data processing module, and result feedback and adjustment module allows athletes to clearly understand their strengths and weaknesses during running and make targeted improvements. Reasonable stride length, coordinated stride frequency, and stable body center of gravity control not only help improve running efficiency but also effectively reduce the risk of sports injuries. The new ideal stride length LB... new A dynamic adjustment mechanism is formed to address the cyclical influence of the ideal stride length LB in the stride length score BH. It optimizes the ideal stride length LB in real time based on the overall movement quality score ZT, enabling the training program to be flexibly adjusted according to the athlete's real-time performance, adapting to the physical conditions and training progress of different athletes, and achieving personalized and interactive corrective training.

[0065] In addition, stride length score (BH), overall movement quality score (ZT), and ideal stride length score (LB) are also included. new The calculation formula adopts a scientific and reasonable calculation method, which fully considers the complex relationship between various indicators. By comparing and quantifying actual data with ideal data, the evaluation results are more accurate and objective, providing athletes and coaches with a reliable basis for decision-making. Compared with the simple data analysis methods of existing technologies, the calculation method of this system is more scientific and reasonable.

[0066] Referring to Figure 1, in this implementation scheme, the formula for calculating the stride score BH based on step III is as follows:

[0067] ;

[0068] in:

[0069] BH represents stride score;

[0070] SB stands for actual stride length. SB reflects the average number of meters taken by an athlete during running, which is the average of all steps taken and the data processed by the athlete.

[0071] LB is the ideal stride length, which reflects the ideal average distance that an athlete sets based on physical condition data and their actual training status.

[0072] When setting the ideal stride length (LB) initially, the body condition data is height, and the specific calculation formula is LB = G × k;

[0073] G represents the athlete's height in meters;

[0074] k is a proportionality coefficient, and the value of k ranges from {0.4 to 0.6};

[0075] If the actual stride length SB is large, it will be close to 0.6;

[0076] If the actual stride length SB is small, it will be close to 0.4.

[0077] In this embodiment, The calculation section eliminates the positive or negative nature of the deviation ratio and focuses solely on the magnitude of the deviation. Its absolute value calculation ignores the direction of the deviation, retaining only its numerical value. This ensures that subsequent score calculations will not be abnormal due to the direction of the deviation, allowing the score to reasonably reflect the degree to which the stride deviates from the ideal state. The overall calculation converts the deviation ratio into a percentage. Multiplying it by 100 converts the decimal deviation ratio into a common percentage representation, making it easier to intuitively understand the magnitude of the deviation. Then, subtracting the percentage of deviation from 100 means that the larger the deviation, the lower the score, and the smaller the deviation, the higher the score. With 100 as the maximum score, this method can intuitively reflect the rationality of the stride. The stride score BH is the final calculation result, which directly reflects the rationality of the stride in the current training. The higher the score, the closer the stride is to the ideal state.

[0078] This implementation compares the actual stride length SB with the ideal stride length LB. By calculating the deviation ratio and converting it into a score, it can intuitively and accurately quantify the rationality of the athlete's stride length. In traditional sports training, coaches can often only rely on experience to roughly judge whether the stride length is appropriate, lacking precise quantitative indicators. This formula provides a clear numerical basis for stride length assessment, enabling athletes and coaches to clearly understand the gap between the current stride length and the ideal state.

[0079] Based on stride length score (BH), athletes can clearly know whether their stride length is too large or too small. If the stride length score (BH) is low, it means that the stride length deviates significantly from the ideal value and needs to be adjusted accordingly. If the stride length score (BH) is high, it means that the stride length is reasonable and can be maintained. This clear feedback helps athletes to quickly adjust their stride length during training and improve training efficiency.

[0080] The calculation method implemented here is uniform and objective, unaffected by subjective factors. Regardless of the training environment or the athletes, the same standard can be used to assess stride rationality, making the assessment results comparable and valuable for reference.

[0081] Referring to Figure 1, in this implementation scheme, the formula for calculating the overall motion quality score ZT based on step III is as follows:

[0082] ;

[0083] in:

[0084] ZT represents the overall quality score of the movement.

[0085] SP stands for actual cadence. SP reflects the average number of steps per minute that an athlete actually takes during running, as measured and calculated.

[0086] LP is the ideal stride frequency. LP is calculated based on the athlete's ideal stride length LB and training goals. The specific calculation formula is LP=v / LB, where v is the target speed and is the training goal of meters per minute.

[0087] SY is the body center of gravity offset distance. SY reflects the average offset distance of the body center of gravity in the horizontal direction that is actually measured and calculated during the running process, i.e., the center of gravity offset data.

[0088] LY is the ideal center of gravity offset distance, which is set based on the offset degree of different athletes in history.

[0089] In this embodiment, The calculation section calculates the ratio of actual cadence (SP) to ideal cadence (LP). Cadence is a crucial factor affecting running efficiency and movement quality. Ideal cadence (LP) is the optimal value determined based on the athlete's physical condition data and actual training status. By dividing the actual cadence (SP) by the ideal cadence (LP), the relative relationship between the two can be obtained. If the result is greater than 1, it indicates that the actual cadence (SP) is higher than the ideal cadence (LP); if the result is less than 1, it indicates that the actual cadence (SP) is lower than the ideal cadence (LP). The calculation section reflects the rationality of stride frequency and is an important factor in comprehensively evaluating stride length and stride frequency. The calculation results yield a comprehensive stride length and frequency score. The stride length score BH is multiplied by the relative ratio of stride frequency, taking into account the influence of both stride length and stride frequency on running motion. Since stride length and stride frequency are interrelated, running motion is more efficient only when both are in a reasonable state.

[0090] The calculation section measures the ratio of the body's center of gravity offset distance SY to the ideal center of gravity offset distance LY. The stability of the body's center of gravity is crucial for the quality of running motion. The ideal center of gravity offset distance LY is a standard value under professional specifications. By dividing the actual body's center of gravity offset distance SY by the ideal offset distance LY, the relative relationship between the actual offset and the ideal state can be obtained. If the result is greater than 1, it indicates that the body's center of gravity offset is too large; if the result is less than 1, the offset is small. It reflects the rationality of the body's center of gravity offset and is a key factor in evaluating the overall quality of running motion. Calculation part and The overall movement quality score ZT is obtained by multiplying the calculated components. It combines the stride length and frequency scores with the relative proportion of body center of gravity shift, taking into account the influence of three important factors on the quality of running movements. These three factors together determine the overall quality of running movements. This multiplication operation can comprehensively evaluate the quality of running movements. The overall movement quality score ZT is a quantitative assessment of the overall quality of running movements. The higher the score, the more reasonable the running movements are in terms of stride length, stride frequency, and body center of gravity control.

[0091] In running, stride length and stride frequency are two important factors that are interconnected and influence each other. Existing evaluation methods often only assess stride length or stride frequency separately. However, this embodiment combines the stride length score (BH) with the relative ratio of stride frequency, comprehensively considering the synergistic effect of the two. This makes the evaluation results more reflective of the athlete's overall running efficiency and coordination, avoiding one-sided evaluations caused by focusing on only a single indicator. In addition to stride length and stride frequency, the stability of the body's center of gravity is also a key factor affecting the quality of running movements. Therefore, this embodiment combines the comprehensive stride length and frequency scores with the body's center of gravity shift ratio, comprehensively considering the three important aspects of stride length, stride frequency, and body center of gravity control. This allows the evaluation results to more accurately reflect the overall quality of the athlete's running movements and identify potential problems and deficiencies.

[0092] By calculating the Overall Movement Quality Score (ZT), it is possible to determine whether an athlete's running rhythm is reasonable. If the stride length is reasonable but the stride frequency is too fast or too slow, the ZT will also be affected. This helps athletes find the optimal combination of stride length and stride frequency, optimize running rhythm, and improve athletic performance. In addition, excessive shift of the body's center of gravity can also reduce running efficiency and increase the risk of injury to athletes. By assessing the shift of the body's center of gravity, athletes can be reminded to pay attention to maintaining body balance and reduce unnecessary swaying of the center of gravity, thereby improving the safety of the sport.

[0093] Different athletes have different physical conditions and athletic abilities, so the suitable combination of stride length and stride frequency also varies. The calculation section can calculate a comprehensive score based on the athlete's actual stride length and stride frequency, providing an important reference for developing personalized training plans. Finally, based on the overall movement quality score (ZT), athletes can understand their performance in various aspects during running. If the overall movement quality score (ZT) is low, it indicates problems in stride length, stride frequency, and body center of gravity control, which need to be improved in a targeted manner. This comprehensive assessment helps athletes continuously optimize their running movements and improve their athletic performance.

[0094] Referring to Figure 1, in this implementation scheme: based on step III, the new ideal stride length LB is adjusted. new The calculation formula is as follows:

[0095] ;

[0096] in:

[0097] LB new For a new ideal stride;

[0098] And the new ideal stride LB new It will be used as a replacement correction value for the ideal stride length (LB) for training, correction and interaction with athletes;

[0099] Based on the new ideal stride length LB new The corrective assessment of the ideal stride length (LB) is as follows:

[0100] If the new ideal stride LB new If the stride length (LB) equals the ideal stride length, it reflects that the athlete has completed training corrections.

[0101] If the new ideal stride LB new If the stride length (LB) is not equal to the ideal stride length, it reflects that the athlete has not completed the training correction.

[0102] In this embodiment, The core significance of this calculation lies in dynamically adjusting the key training parameter, ideal stride length (LB), based on the athlete's current overall running performance. The overall performance score (ZT) comprehensively reflects the athlete's performance in stride length, stride frequency, and body center of gravity control. The calculation quantifies this overall performance as an adjustment to the ideal stride length (LB), making LB no longer a fixed value but flexible enough to vary based on the athlete's actual training results and real-time condition. Furthermore, the overall movement quality score (ZT) is a quantitative representation of the athlete's overall running movement quality; a higher score indicates the movement is closer to the ideal state, while a lower score indicates more areas for improvement. The value is calculated by subtracting 1 from the value of the ideal stride length (LB). This ratio yields an adjustment coefficient, which is used to adjust the expected stride length (LB).

[0103] The Overall Movement Quality Score (ZT) reflects the athlete's overall performance in running motion, through... The calculation can dynamically adjust the ideal stride length LB based on the overall score. When the overall movement quality score ZT is low, it indicates that there is a problem with the current running movement, and the ideal stride length LB needs to be adjusted appropriately to improve the movement quality. When the overall movement quality score ZT is high, it indicates that the current stride length and movement are relatively reasonable, and the ideal stride length LB can be maintained and fine-tuned. This dynamic adjustment mechanism makes the training program more flexible and adaptable, and can be optimized based on the athlete's real-time performance.

[0104] New Ideal Stroke LBnew The ideal stride length (LB) is fed back into the stride length score (BH), thus forming a closed-loop feedback system. During training, the system continuously monitors and evaluates the quality of the running motion, and adjusts the ideal stride length (LB) based on the evaluation results. The athlete then adjusts the ideal stride length (LB) according to the new ideal stride length (BH). new During training, the system continues to evaluate and adjust. This cyclical feedback mechanism enables athletes to train more scientifically and precisely, continuously improving training effectiveness and athletic performance. Through this cyclical influence, the system can make precise adjustments to address specific issues faced by athletes. For instance, if a low overall movement quality score (ZT) is due to an unreasonable stride length, the system will adjust the ideal stride length (LB) accordingly, guiding the athlete to train towards a more reasonable stride length. This targeted training avoids blind training, improves training efficiency, and achieves interactivity in the training correction process, enabling athletes to reach their training goals more quickly.

[0105] It should be noted that any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should also be within the scope of protection of this invention.
