Description

Technical Field

[0001] This application relates to the field of terminals, and particularly to a method and a terminal device for evaluating the risk of sports injuries. Background Art

[0002] Sports such as running are important activities in human life. At the same time, in order to enhance the scientificity and safety of sports, more and more terminal devices can detect the user's sports data and present the sports data to the user. The user can preliminarily evaluate the possible injuries during the sports process based on the sports data. However, since the sports data is usually relatively complex, the user often cannot accurately evaluate the possible injuries during the sports process based on the sports data. Therefore, there is an urgent need for a method for evaluating the risk of sports injuries to analyze and process the sports data, so as to intuitively provide the evaluation result to the user.

[0003] In the prior art, some terminal devices can evaluate the possible injuries to organs such as the heart and lungs of the user based on the sports data of heart rate, stride, exercise duration, exercise speed, number of steps, breathing frequency, and blood pressure during the user's exercise process, but no terminal device has been able to evaluate the possible injuries to the knees. Summary of the Invention

[0004] In view of this, this application provides a method and a terminal device for evaluating the risk of sports injuries, which can evaluate the risk of knee injuries based on the user's sports data.

[0005] To achieve the above object, in a first aspect, an embodiment of this application provides a method for evaluating the risk of sports injuries. The method includes: obtaining sports data for a first time period, where the sports data includes at least one impact value, at least one left touchdown balance value, and at least one right touchdown balance value. The impact value is used to indicate the reaction force borne during the touchdown of the left foot or the right foot, the left touchdown balance value is used to indicate the duration of the left foot touchdown, and the right touchdown balance value is used to indicate the duration of the right foot touchdown; determining a left impact value accumulation amount corresponding to the first time period and a right impact value accumulation amount corresponding to the first time period based on at least one of the impact values, at least one of the left touchdown balance values, and at least one of the right touchdown balance values. The left impact value accumulation amount is used to indicate the cumulative reaction force borne during the left foot touchdown within the first time period, and the right impact value accumulation amount is used to indicate the cumulative reaction force borne during the right foot touchdown within the first time period; determining the risk of knee injury corresponding to the first time period based on the left impact value accumulation amount and the right impact value accumulation amount.

[0006] In the embodiments of the present application, motion data for a first time period can be obtained, including at least one impact value, at least one left touchdown balance value, and at least one right touchdown balance value. Since the impact value can indicate the reaction force borne during the touchdown of the left foot or the right foot, the left touchdown balance value is used to indicate the duration of the left foot touchdown, and the right touchdown balance value is used to indicate the duration of the right foot touchdown. Therefore, based on at least one impact value and at least one left touchdown balance value within the first time period, the cumulative reaction force borne during the left foot touchdown within the first time period, that is, the left impact value accumulation, can be determined. Based on at least one impact value and at least one right touchdown balance value within the first time period, the cumulative reaction force borne during the right foot touchdown within the first time period, that is, the right impact value accumulation, can be determined. When the left impact value accumulation and the right impact value accumulation are determined, the risk of knee injury within the first time period can be conveniently and quickly evaluated based on the magnitude of the left impact value accumulation, the magnitude of the right impact value accumulation, and the difference between the left impact value accumulation and the right impact value accumulation, facilitating the user to fully understand the health condition of the knee during the exercise process, taking preventive and protective measures in a timely manner, and improving the safety of the user's exercise.

[0007] In some embodiments, the first time period includes at least one moment. At least one impact value can include the impact value corresponding to each moment. At least one left touchdown balance value can include the left touchdown balance value corresponding to each moment. At least one right touchdown balance value can include the right touchdown balance value corresponding to each moment.

[0008] In some embodiments, the impact value is the impact peak value, and the impact peak value is used to indicate the maximum reaction force borne during the touchdown of the left foot or the right foot; and / or, the left touchdown balance value is used to indicate the ratio of the duration of the left foot touchdown to the total touchdown duration, and the right touchdown balance value is used to indicate the ratio of the duration of the right foot touchdown to the total touchdown duration. It can be understood that the impact value can also indicate the force borne at any moment during the touchdown of the left foot or the right foot, or the impact value can be the impact average value, and the impact average value is used to indicate the average force borne during the touchdown of the left foot or the right foot.

[0009] In some embodiments, determining the knee injury risk corresponding to the first time period based on the left impact value accumulation and the right impact value accumulation includes: if the left impact value accumulation is greater than a first threshold, or the right impact value accumulation is greater than the first threshold, or the absolute value of the difference between the left impact value accumulation and the right impact value accumulation is greater than a second threshold, it is determined that there is a knee injury risk within the first time period.

[0010] Among them, if the cumulative amount of the left impact value is greater than the first threshold, the force on the left knee is relatively large, and damage may have occurred or already occurred, and it can be determined that there is a risk of knee injury within the first time period; or, if the cumulative amount of the right impact value is greater than the first threshold, the force on the right knee is relatively large, and damage may have occurred or already occurred, and it can be determined that there is a risk of knee injury within the first time period; or, if the absolute value of the difference between the cumulative amount of the left impact value and the cumulative amount of the right impact value is greater than the second threshold, the difference between the force on the left knee and the force on the right knee is relatively large, so it can be determined that there is a risk of knee injury within the first time period.

[0011] In some embodiments, the method further includes: if it is determined that there is a risk of knee injury, presenting a first prompt message, where the first prompt message is used to prompt the existence of the risk of knee injury, so as to further timely and intuitively remind the user and ensure the safety of the user's exercise.

[0012] In some embodiments, the method further includes: if the difference between the cumulative amount of the left impact value and the cumulative amount of the right impact value is greater than a third threshold, presenting a second prompt message, where the second prompt message is used to prompt that the risk of injury to the left knee is greater than the risk of injury to the right knee; if the difference between the cumulative amount of the right impact value and the cumulative amount of the left impact value is greater than the third threshold, presenting a third prompt message, where the third prompt message is used to prompt that the risk of injury to the right knee is greater than the risk of injury to the left knee.

[0013] That is to say, when the cumulative amount of the left impact value is greater than the cumulative amount of the right impact value and the difference between the cumulative amount of the left impact value and the cumulative amount of the right impact value is greater than the third threshold, the user can be reminded that the risk of injury to the left knee is greater than the risk of injury to the right knee; when the cumulative amount of the right impact value is greater than the cumulative amount of the left impact value and the difference between the cumulative amount of the right impact value and the cumulative amount of the left impact value is greater than the third threshold, the user can be reminded that the risk of injury to the right knee is greater than the risk of injury to the left knee, so as to timely remind the user and further improve the safety during exercise.

[0014] In some embodiments, determining the cumulative amount of the left impact value corresponding to the first time period based on at least one of the impact values, at least one of the left ground contact balance values, and at least one of the right ground contact balance values includes:

[0015] Limpacksum = ((impack_1 + … + impack_n) * (Lbalance_1 + … + Lbalance_n_)) / n; where Limpacksum is the cumulative left impact value corresponding to the first time period, impack_n is the impact value corresponding to the nth moment, and Lbalance_n is the left touchdown balance value corresponding to the nth moment.

[0016] In some embodiments, determining the cumulative right impact value corresponding to the first time period based on at least one of the impact values, at least one of the left touchdown balance values, and at least one of the right touchdown balance values includes:

[0017] Rimpacksum = (impack_1 + … + impack_n) - Limpacksum; where Rimpacksum is the cumulative right impact value corresponding to the first time period.

[0018] In a second aspect, an embodiment of the present application provides a device for evaluating the risk of sports injuries, and the device has the functions of implementing the behaviors in the above aspects and the possible implementation manners of the above aspects. The functions can be implemented by hardware or by hardware executing corresponding software. The hardware or software includes one or more modules or units corresponding to the above functions. For example, a transceiver module or unit, a processing module or unit, an acquisition module or unit, etc.

[0019] In some embodiments, the device may include an acquisition module and a determination module.

[0020] The acquisition module is configured to acquire motion data for a first time period, the motion data including at least one impact value, at least one left touchdown balance value, and at least one right touchdown balance value, the impact value being used to indicate the reaction force borne during touchdown of the left or right foot, the left touchdown balance value being used to indicate the duration of touchdown of the left foot, and the right touchdown balance value being used to indicate the duration of touchdown of the right foot;

[0021] The determination module is configured to determine the cumulative left impact value corresponding to the first time period and the cumulative right impact value corresponding to the first time period based on at least one of the impact values, at least one of the left touchdown balance values, and at least one of the right touchdown balance values, the cumulative left impact value being used to indicate the cumulative reaction force borne during touchdown of the left foot within the first time period, and the cumulative right impact value being used to indicate the cumulative reaction force borne during touchdown of the right foot within the first time period; and determine the risk of knee injury corresponding to the first time period based on the cumulative left impact value and the cumulative right impact value.

[0033] The method and terminal device for evaluating the risk of sports injuries provided by the embodiments of the present application can be applied to terminal devices such as mobile phones, tablet computers, wearable devices (such as smart watches and bracelets), vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, laptop computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), etc. The embodiments of the present application do not impose any restrictions on the specific types of terminal devices.

[0034] Figure 1 FIG. 4 is a schematic structural diagram of a terminal device 100 provided by an embodiment of the present application. The terminal device 100 may include a processor 110, a memory 120, a communication module 130, etc.

[0035] Among them, the processor 110 may include one or more processing units, and the memory 120 is used to store program codes and data. In the embodiments of the present application, the processor 110 can execute the computer execution instructions stored in the memory 120 to control and manage the actions of the terminal device 100.

[0036] The communication module 130 can be used for communication between various internal modules of the terminal device 100, or communication between the terminal device 100 and other external terminal devices, etc. Exemplarily, if the terminal device 100 communicates with other terminal devices in a wired connection manner, the communication module 130 may include interfaces, such as a USB interface. The USB interface can be an interface that conforms to the USB standard specification, specifically a Mini USB interface, a Micro USB interface, a USB Type C interface, etc. The USB interface can be used to connect a charger to charge the terminal device 100, and can also be used for data transmission between the terminal device 100 and peripheral devices. It can also be used to connect headphones to play audio through the headphones. This interface can also be used to connect other terminal devices.

[0037] Alternatively, the communication module 130 may include audio devices, radio frequency circuits, Bluetooth chips, wireless fidelity (Wi-Fi) chips, near-field communication (NFC) modules, etc., and can realize the interaction between the terminal device 100 and other terminal devices in a variety of different ways.

[0038] Optionally, the terminal device 100 may further include a display screen 140, which can display images, videos, etc. in the human-computer interaction interface. Exemplarily, the terminal device 100 can present image-type prompt information to the user through the display screen 140.

[0039] Optionally, the terminal device 100 may further include a speaker 150, also known as a "horn", which is used to convert an audio electrical signal into a sound signal. Exemplarily, the terminal device 100 can present sound-type prompt information to the user through the speaker 150.

[0040] Optionally, the terminal device 100 may further include a motor 160, which can generate a vibration prompt. The motor 160 can be used for touch vibration feedback or to present vibration-type prompt information to the user, such as beeping.

[0041] Optionally, the terminal device 100 may further include a sensor 170, which can be used to detect various signals in the environment where the terminal device 100 is located and convert the signal into a corresponding electrical signal. Exemplarily, the sensor 170 may include one or more of a gyroscope sensor, an acceleration sensor, and a pressure sensor. The gyroscope sensor can be used to determine the motion posture of the terminal device 100. In some embodiments, the angular velocity of the terminal device 100 around three axes (i.e., the x, y, and z axes) can be determined by the gyroscope sensor. The acceleration sensor can detect the magnitude of the acceleration of the terminal device 100 in each direction (generally three axes). When the terminal device 100 is stationary, the magnitude and direction of gravity can be detected, and it can also be used to identify the posture of the terminal device 100. The pressure sensor is used to sense the pressure signal and can convert the pressure signal into an electrical signal. The terminal device 100 can detect the user's motion data through one or more of the gyroscope sensor, the acceleration sensor, and the pressure sensor, such as the reaction force received during the user's foot contact during exercise and the duration of foot contact.

[0042] It should be understood that in addition to Figure 1 the various components or modules listed above, the structure of the terminal device 100 is not specifically limited in the embodiments of the present application. In some other embodiments of the present application, the terminal device 100 may further include more or fewer components than shown in the figure, or combine certain components, or split certain components, or have different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0043] To facilitate understanding of the technical solutions in the embodiments of the present application, the application scenarios of the embodiments of the present application are first introduced below.

[0044] Please refer to Figure 2 for a schematic diagram of a scenario provided by the embodiments of the present application.

[0045] The user can carry the first terminal 210 and / or the second terminal 220 during exercise. Exemplarily, the first terminal 210 can be a mobile phone, and the second terminal can be a wearable device such as a smart watch.

[0046] In some embodiments, the first terminal 210 and the second terminal 220 can be communicatively connected by means such as Bluetooth. The second terminal 220 includes sensors. The second terminal 220 can collect the user's motion data through the sensors and send the motion data to the first terminal 210 through the communication connection. The first terminal 210 can receive the motion data and analyze and process the motion data, so as to evaluate the risk of knee injury of the user. The first terminal 210 can display the evaluation result, or can also send the evaluation result to the second terminal 220 so that the second terminal 220 displays the evaluation result.

[0047] Alternatively, in some other embodiments, the second terminal 220 can collect the user's motion data through the sensors, analyze and process the motion data, so as to evaluate the risk of knee injury of the user, and can also display the evaluation result.

[0048] Alternatively, in some other embodiments, the first terminal 210 can collect the user's motion data through the sensors, analyze and process the motion data, so as to evaluate the risk of knee injury of the user, and can also display the evaluation result.

[0049] That is to say, when evaluating the risk of sports injury, it can include three functions: collecting motion data, analyzing the motion data to obtain an evaluation result, and displaying the evaluation result. These three functions can be completed by one terminal device, or can be completed by multiple terminal devices in cooperation.

[0050] The technical solution of the present application will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and for the same or similar concepts or processes, they may not be repeated in some embodiments.

[0051] Please refer to Figure 3 , which is a flowchart of a method for evaluating the risk of sports injury provided by an embodiment of the present application. Among them, Figure 3 Taking the first terminal as an example, the method for evaluating the risk of sports injury will be described. It can be understood that this method can also be applied to the second terminal. It should be noted that this method is not limited by Figure 3 the specific order described below, and it should be understood that in other embodiments, the order of some steps of this method can be interchanged according to actual needs, or some of the steps can also be omitted or deleted. The method includes the following steps:

[0052] S301, the first terminal obtains the motion data for the first time period, where the motion data includes at least one impact value, at least one left touchdown balance value, and at least one right touchdown balance value. The impact value is used to indicate the reaction force borne during the touchdown of the left or right foot, the left touchdown balance value is used to indicate the duration of the left foot touchdown, and the right touchdown balance value is used to indicate the duration of the right foot touchdown.

[0053] In some embodiments, the motion data can be used to illustrate the user's running posture, so the motion data can also be referred to as running posture data.

[0054] In some embodiments, the first time period includes at least one moment. The at least one impact value can include the impact value corresponding to each moment, the at least one left touchdown balance value can include the left touchdown balance value corresponding to each moment, and the at least one right touchdown balance value can include the right touchdown balance value corresponding to each moment.

[0055] In some embodiments, the impact value can be the peak impact value, and the peak impact value is used to indicate the maximum force borne during the touchdown of the left or right foot. It can be understood that the impact value can also indicate the force borne at any moment during the touchdown of the left or right foot, or the impact value can be the average impact value, and the average impact value is used to indicate the average force borne during the touchdown of the left or right foot.

[0056] In some embodiments, the left touchdown balance value can be used to indicate the ratio of the duration of the left foot touchdown to the total touchdown duration, and the right touchdown balance value can be used to indicate the ratio of the duration of the right foot touchdown to the total touchdown duration. Exemplarily, during the exercise process of the user, the ratio of the duration of the left foot touchdown to the total touchdown duration is 52%, that is, the left touchdown balance value is 48%; the ratio of the duration of the right foot touchdown to the total touchdown duration is 48%, that is, the right touchdown balance value is 48%.

[0057] Among them, the touchdown duration refers to the duration from when the foot touches the ground to when it leaves the ground; the left and right touchdown balance is the proportion of the touchdown time of the left and right feet, the balance of the touchdown time of the left and right feet during running, which is used to measure running symmetry. The smaller the difference between the left touchdown balance value and the right touchdown balance value, the better the running symmetry. In some embodiments, both the left touchdown balance value and the right touchdown balance value can be 50%. Long-term severe left-right imbalance may increase the risk of injury to one side of the lower limb.

[0058] In some embodiments, the first time period may be a preset time period. Exemplarily, the first time period may be a time period of any duration between 5 s (seconds) and 10 s. The first terminal may acquire the motion data within every 5 s - 10 s, and then determine the knee injury risk every 5 s - 10 s through the following steps. It can be understood that the first terminal may also determine the first time period in other ways, and the first time period may also be a time period of other durations.

[0059] In some embodiments, the first terminal may acquire the motion data of the first time period from other devices such as a second terminal. Exemplarily, the first terminal is a mobile phone, the second terminal is a smart watch, the mobile phone is communicatively connected to the smart watch, and the mobile phone may acquire the motion data of the first time period from the smart watch through this communication connection. Alternatively, the first terminal is a mobile phone, the second terminal is another mobile phone, and this mobile phone may acquire the motion data of the first time period from the other mobile phone. Alternatively, the first terminal is a mobile phone, and the first terminal may acquire the motion data of the first time period from a server. Alternatively, in some embodiments, the first terminal includes a sensor, and the first terminal may acquire the motion data of the first time period from this sensor. Alternatively, in some other embodiments, the first terminal includes a memory, and the memory has previously stored the motion data of the first time period, and the first terminal may acquire this motion data from the memory.

[0060] S302. The first terminal determines the left impact value accumulation corresponding to the first time period and the right impact value accumulation corresponding to the first time period based on at least one impact value, at least one left touchdown balance value, and at least one right touchdown balance value. The left impact value accumulation is used to indicate the cumulative reaction force borne during the touchdown of the left foot within the first time period, and the right impact value accumulation is used to indicate the cumulative reaction force borne during the touchdown of the right foot within the first time period.

[0061] Since the impact value can indicate the reaction force borne during the touchdown of the left foot or the right foot, the left touchdown balance value is used to indicate the touchdown duration of the left foot, and the right touchdown balance value is used to indicate the touchdown duration of the right foot, therefore, based on at least one impact value and at least one left touchdown balance value within the first time period, the cumulative reaction force borne during the touchdown of the left foot within the first time period, that is, the left impact value accumulation, can be determined. Based on at least one impact value and at least one right touchdown balance value within the first time period, the cumulative reaction force borne during the touchdown of the right foot within the first time period, that is, the right impact value accumulation, can be determined.

[0062] In some embodiments, the left impact value accumulation corresponding to the first time period may be determined through the following formula 1:

[0063] Limpacksum = ((impack_1 + … + impack_n) * (Lbalance_1 + … + Lbalance_n)) / n (Formula 1)

[0064] Among them, Limpacksum is the cumulative amount of left - side impact values corresponding to the first time period, impack_n is the impact value corresponding to the nth moment, and Lbalance_n is the left - side touchdown balance value corresponding to the nth moment.

[0065] In some embodiments, when the cumulative amount of left - side impact values corresponding to the first time period is determined, the cumulative amount of right - side impact values corresponding to the first time period can be determined by the following Formula 2:

[0066] Rimpacksum = (impack_1 + … + impack_n) - Limpacksum (Formula 2)

[0067] Among them, Rimpacksum is the cumulative amount of right - side impact values corresponding to the first time period.

[0068] S303. The first terminal determines the knee injury risk corresponding to the first time period based on the cumulative amount of left - side impact values and the cumulative amount of right - side impact values.

[0069] When the cumulative amount of left - side impact values and the cumulative amount of right - side impact values are determined, the risk of knee injury within the first time period can be conveniently and quickly evaluated based on the magnitude of the cumulative amount of left - side impact values, the magnitude of the cumulative amount of right - side impact values, and the difference between the cumulative amount of left - side impact values and the cumulative amount of right - side impact values, which is convenient for the user to fully understand the health condition of the knee during exercise and take preventive and protective measures in a timely manner.

[0070] In some embodiments, if the cumulative amount of left - side impact values is greater than the first threshold, the force on the left knee is relatively large, and injury may have occurred or is likely to occur, so it can be determined that there is a knee injury risk within the first time period; or, if the cumulative amount of right - side impact values is greater than the first threshold, the force on the right knee is relatively large, and injury may have occurred or is likely to occur, so it can be determined that there is a knee injury risk within the first time period; or, if the absolute value of the difference between the cumulative amount of left - side impact values and the cumulative amount of right - side impact values is greater than the second threshold, the difference between the force on the left knee and the force on the right knee is relatively large, so it can be determined that there is a knee injury risk within the first time period.

[0071] In some embodiments, if it is determined that there is a risk of knee injury, the first terminal presents a first prompt message, which is used to prompt the existence of a knee injury risk, so as to further timely and intuitively remind the user and ensure the safety of the user's exercise. In other embodiments, the first terminal may send a fourth prompt message to other devices such as the second terminal, so as to instruct the second terminal and other devices to display the fourth prompt message, where the fourth prompt message is used to prompt the existence of a knee injury risk, and the fourth prompt message may be similar to or the same as the first prompt message. In some embodiments, the first terminal or other devices may present the first prompt message in one or more of the ways of images, graphics, sounds, vibrations, etc.

[0072] Exemplarily, the first terminal is a mobile phone and the second terminal is a smart watch. As Figure 4 shown in a of, the mobile phone can display the first prompt message 401, where the first prompt message 401 includes "There is a risk of knee injury during your running. Please pay attention to adjusting your running posture or slowing down". In addition, the smart watch can display the fourth prompt message 402, and the fourth prompt message 402 includes "There is a risk of knee injury during your running. Please pay attention to adjusting your running posture or slowing down". In some embodiments, the smart watch can also play the fourth prompt message by voice and / or vibrate to facilitate timely reminding of the user.

[0073] In some embodiments, if the difference between the cumulative left impact value and the cumulative right impact value is greater than a third threshold, the first terminal presents a second prompt message, which is used to prompt that the risk of left knee injury is greater than the risk of right knee injury; or, if the difference between the cumulative right impact value and the cumulative left impact value is greater than a third threshold, the first terminal presents a third prompt message, which is used to prompt that the risk of right knee injury is greater than the risk of left knee injury. That is, it is possible to remind the user that the risk of left knee injury is greater than the risk of right knee injury when the cumulative left impact value is greater than the cumulative right impact value and the difference between the cumulative left impact value and the cumulative right impact value is greater than the third threshold; when the cumulative right impact value is greater than the cumulative left impact value and the difference between the cumulative right impact value and the cumulative left impact value is greater than the third threshold, remind the user that the risk of right knee injury is greater than the risk of left knee injury, so as to timely remind the user and further improve the safety during exercise.

[0074] In some embodiments, if the difference between the cumulative left impact value and the cumulative right impact value is greater than a third threshold, the first terminal may send a fifth prompt message to other devices such as the second terminal, so as to instruct the other device to present the fifth prompt message, where the fifth prompt message is used to prompt that the injury risk of the left knee is greater than that of the right knee, and the fifth prompt message may be similar to or the same as the second prompt message. In some embodiments, if the difference between the cumulative right impact value and the cumulative left impact value is greater than a third threshold, the first terminal may send a sixth prompt message to other devices such as the second terminal, so as to instruct the other device to present the sixth prompt message, where the sixth prompt message is used to prompt that the injury risk of the left knee is greater than that of the right knee, and the sixth prompt message may be similar to or the same as the third prompt message.

[0075] In some embodiments, the first threshold, the second threshold, and the third threshold may be pre-set values. In some embodiments, the third threshold may be the same as the second threshold. It should be noted that the embodiments of the present application do not limit the manner of setting the first threshold, the second threshold, and the third threshold, nor do they limit the specific values of the first threshold, the second threshold, and the third threshold.

[0076] In some embodiments, the manner of presenting the second prompt message, the third prompt message, the fourth prompt message, the fifth prompt message, and the sixth prompt message may be the same as or similar to the manner of prompting the first prompt message.

[0077] Exemplarily, the first terminal is a mobile phone and the second terminal is a smart watch. As Figure 4 shown in b, the mobile phone may display the second prompt message 403, where the second prompt message 403 includes "There is a risk of left knee injury during your running. Please pay attention to adjusting your running posture or slowing down". In addition, the smart watch may display the fifth prompt message 404, and the fifth prompt message 404 includes "There is a risk of left knee injury during your running.

[0078] In an embodiment of the present application, motion data for a first time period can be obtained, including at least one impact value, at least one left touchdown balance value, and at least one right touchdown balance value. Since the impact value can indicate the reaction force borne during the touchdown of the left foot or the right foot, the left touchdown balance value is used to indicate the duration of the left foot touchdown, and the right touchdown balance value is used to indicate the duration of the right foot touchdown. Therefore, based on at least one impact value and at least one left touchdown balance value within the first time period, the cumulative reaction force borne during the left foot touchdown within the first time period, that is, the left impact value accumulation, can be determined. Based on at least one impact value and at least one right touchdown balance value within the first time period, the cumulative reaction force borne during the right foot touchdown within the first time period, that is, the right impact value accumulation, can be determined. When the left impact value accumulation and the right impact value accumulation are determined, the risk of knee injury within the first time period can be conveniently and quickly evaluated based on the magnitude of the left impact value accumulation, the magnitude of the right impact value accumulation, and the difference between the left impact value accumulation and the right impact value accumulation, facilitating the user to fully understand the health condition of the knee during the exercise process, taking preventive and protective measures in a timely manner, and improving the safety of the user's exercise.

[0079] Please refer to Figure 5 , which is a flowchart of a method for evaluating the risk of sports injury provided by an embodiment of the present application.

The method includes the following steps:

[0080] S501, the first terminal establishes a communication connection with the second terminal.

[0081] In some embodiments, this communication connection can be a Bluetooth connection. Of course, in actual applications, this communication connection can also be other types of connections.

[0082] In some embodiments, S501 can be omitted.

[0083] S502, the user turns on the knee injury risk reminder function on the first terminal.
