Description

Technical Field

[0001] This invention relates to the field of treadmill technology, specifically to a heart rate-based intelligent treadmill and exercise training method. Background Technology

[0002] With the improvement of living standards, people are paying more and more attention to physical management. Therefore, fitness has become a way for most people to improve their physical fitness. However, it is not easy for most people to exercise scientifically and effectively. Low-intensity fitness may not achieve the desired effect, while excessive fitness may have the opposite effect. Therefore, having a scientific and effective exercise prescription is particularly important.

[0003] Everyone's physical condition is different, so you can't blindly use the same set of exercise methods. Only by customizing a scientific exercise prescription based on each person's physical condition can you achieve the most effective fitness results. Summary of the Invention

[0004] The purpose of this invention is to provide a heart rate-based intelligent treadmill and exercise training method, which can customize a scientific exercise prescription according to the user's actual situation to achieve the most effective exercise results.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] Heart rate-based exercise training methods include the following steps:

[0007] S1. Obtain the instantaneous heart rate data of the runner at the moment of completing the preset cardiorespiratory endurance test prescription, and calculate the maximum oxygen uptake by combining the instantaneous heart rate data with the runner's basic information;

[0008] S2. Obtain the oxygen uptake percentage by referring to the maximum oxygen uptake and oxygen uptake percentage table, and calculate the target heart rate zone by combining the oxygen uptake percentage, gender, and age.

[0009] S3. Execute an exercise prescription based on the target heart rate zone in step S2 and obtain the actual heart rate during exercise. If the actual heart rate deviates from the target heart rate zone, adjust the exercise intensity to maintain the actual heart rate within the target heart rate zone.

[0010] Preferably, the preset cardiopulmonary endurance test prescription is divided into 6 test stages: the first stage is a slow walk at a speed of 2 km / h for 1 minute; the second stage is a slow walk at a speed of 3 km / h for 2 minutes; the third stage is a slow walk at a speed of 4 km / h for 3 minutes; the fourth stage is a slow walk at a speed of 5 km / h for 5 minutes; the fifth stage is a fast walk at a speed of 6 km / h for 5 minutes; and the sixth stage is a fast walk at a speed of 7 km / h for 3 minutes; the slope of the above 6 test stages is 0.

[0011] Preferably, the formula for calculating the maximum oxygen uptake in step S1 is:

[0012] ;

[0013] Where: G is the runner's weight; Y is the runner's age; X is the runner's gender, 1 for male and 0.3 for female; T is the total test time; P is the instantaneous heart rate data at the moment the test is completed;

[0014] The runner's basic information includes the runner's age, gender, and weight.

[0015] Preferably, the oxygen uptake percentage comparison table includes the runner's gender, age, the range of maximum oxygen uptake, and the oxygen uptake percentage, with different oxygen uptake percentages corresponding to the range of maximum oxygen uptake for runners of different genders and ages.

[0016] Preferably, the target heart rate range is the range from the minimum heart rate to the maximum heart rate;

[0017] The formula for calculating the minimum heart rate is: ;

[0018] The formula for calculating the maximum heart rate is: ;

[0019] Where: X is the runner's gender, 0 for male and 10 for female; Y is the runner's age; and A is the percentage of oxygen uptake.

[0020] Preferably, the adjustment of exercise intensity in step S3 is to adjust the speed and / or incline of the treadmill, and the adjustment of the speed and / or incline of the treadmill is carried out in manual adjustment mode, automatic adjustment mode, or a combination of manual and automatic adjustment mode.

[0021] Preferably, in the automatic adjustment mode, when the actual heart rate is continuously lower than the target heart rate range for a first preset duration, the exercise intensity is increased; when the actual heart rate is continuously higher than the target heart rate range for a second preset duration, the exercise intensity is decreased.

[0022] Preferably, in the automatic adjustment mode, increasing exercise intensity involves first increasing speed and then increasing incline, and only increasing incline when the speed is still below the target heart rate zone after reaching the maximum speed; in the automatic adjustment mode, decreasing exercise intensity involves first decreasing incline and then decreasing speed, and only decreasing speed when the incline is still above the target heart rate zone after decreasing to 0.

[0023] Preferably, the treadmill speed adjustment method is as follows: for speeds below 4 km / h, increase or decrease by 2 km / h each time; for speeds between 4 km / h and 7 km / h, increase or decrease by 1 km / h each time; for speeds above 7 km / h, increase or decrease by 0.5 km / h each time.

[0024] Preferably, the treadmill incline is increased or decreased by 1° each time.

[0025] The present invention also provides a heart rate-based smart treadmill for performing the above-described exercise training method.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The exercise training method of this invention includes acquiring instantaneous heart rate data after the completion of the cardiorespiratory endurance test prescription, calculating the maximum oxygen uptake based on the runner's weight, age, and gender, then looking up the corresponding oxygen uptake percentage in a table and combining it with gender and age to calculate the target heart rate zone. This target heart rate zone is the safest and most suitable heart rate zone for executing the exercise prescription based on the user's actual situation, which can avoid over-exercising or insufficient exercise intensity, and obtain the optimal exercise prescription for the runner, thereby helping to improve the user experience when using the treadmill. The cardiorespiratory endurance test prescription of this invention is divided into 6 tests, mainly slow walking to fast walking, with the speed increasing in each stage, up to a maximum speed of 7 km / h, and a test cycle of 18-20 minutes. The entire test process does not require running; walking as fast as possible is necessary to achieve the accuracy of the test, as running will affect the heart rate fluctuation and thus ensure the scientific accuracy of the exercise prescription.

[0028] This invention allows runners to adjust their workout regimen to achieve the optimal exercise prescription corresponding to their target heart rate zone, enabling them to create a scientifically sound prescription without the need for a coach. It is suitable for home treadmills. Furthermore, it offers multiple modes for adjusting exercise intensity, including manual, automatic, and hybrid manual / automatic modes. Runners can manually intervene or the system can automatically adjust the intensity based on their individual needs, making it convenient and easy to learn. The manual mode allows for quick adjustments, while the automatic mode offers two options: increasing intensity by first adjusting speed and then incline, and decreasing intensity by first adjusting incline and then speed. This ensures both safety and effectiveness, preventing sudden changes in speed or incline that could cause runners to lose balance or other accidents. Detailed Implementation

[0029] This embodiment provides a heart rate-based smart treadmill, which includes an upper computer and a lower computer that communicate with each other. The lower computer is electrically connected to an incline motor via an incline motor drive current and to a running belt motor via a running belt motor control circuit. The incline motor adjusts the running incline of the treadmill, and the running belt motor adjusts the running belt speed. Different running belt speeds and inclines achieve different exercise intensities.

[0030] In addition, the host computer includes a user registration module, a voice broadcast module, a display circuit, a touch circuit, an external communication circuit, and an upper interface circuit. The lower computer interacts with the upper interface circuit of the host computer through its lower interface circuit. The host computer interacts with the runner through the display circuit, touch circuit, and voice playback circuit to obtain basic sports and health data, including the runner's basic information (such as gender, age, height, weight, etc.), exercise history data, physical condition data, and exercise purpose data.

[0031] The external communication circuit connects to external devices such as heart rate monitoring devices, electrocardiogram (ECG) monitoring devices, and cloud servers via wired or wired communication methods to acquire body status data during running input from these external devices, such as heart rate, body temperature, blood oxygen saturation, ambulatory blood pressure monitoring, and electrocardiogram. The heart rate monitoring device can be a wearable device worn by the runner, such as a smart bracelet.

[0032] The host computer also has a built-in preset cardiorespiratory endurance test prescription and a maximum oxygen uptake calculation module. Before formal running training, the runner selects and executes the preset cardiorespiratory endurance test prescription. When executing the preset cardiorespiratory endurance test prescription, the runner's current heart rate data is input to the host computer through a heart rate monitoring device. After the preset cardiorespiratory endurance test prescription is completed, the instantaneous heart rate data at the moment of test completion is obtained. The maximum oxygen uptake calculation module combines the runner's basic information such as weight, age, gender, total test time, and instantaneous heart rate data at the moment of test completion to calculate the maximum oxygen uptake.

[0033] The formula for calculating maximum oxygen uptake is:

[0034] Where: G is the runner's weight; Y is the runner's age; X is the runner's gender, 1 for male and 0.3 for female; T is the total test time; P is the instantaneous heart rate data at the moment the test is completed;

[0035] The preset cardiorespiratory endurance test prescription consists of 6 test phases: Phase 1 is a 1-minute slow walk at a speed of 2 km / h; Phase 2 is a 2-minute slow walk at a speed of 3 km / h; Phase 3 is a 3-minute slow walk at a speed of 4 km / h; Phase 4 is a 5-minute slow walk at a speed of 5 km / h; Phase 5 is a 5-minute fast walk at a speed of 6 km / h; and Phase 6 is a 3-minute fast walk at a speed of 7 km / h. The total test time for the entire prescription is 19 minutes. The instantaneous heart rate data is the current heart rate data collected by a heart rate monitoring device after the 19th minute of running; the incline of all 6 test phases is 0 degrees.

[0036] Furthermore, the host computer also has a built-in oxygen uptake percentage comparison table, as shown in the table below. The oxygen uptake percentage comparison table includes the runner's gender, age, the range of maximum oxygen uptake, and the oxygen uptake percentage. The range of maximum oxygen uptake for runners of different genders and ages corresponds to different oxygen uptake percentages. The oxygen uptake percentage is obtained through the maximum oxygen uptake and oxygen uptake percentage comparison table.

[0037] Table 1: Oxygen Uptake Percentage Comparison Table

[0038]

[0039] In this embodiment, the host computer also has a built-in heart rate zone calculation module. This heart rate zone calculation module calculates the target heart rate zone by combining the percentage of oxygen uptake, gender, and age. The target heart rate zone is the range from the minimum heart rate to the maximum heart rate.

[0040] The formula for calculating the minimum heart rate is: The formula for calculating the maximum heart rate is: In the above two formulas, X represents the runner's gender, with 0 for males and 10 for females; Y represents the runner's age; and A represents the percentage of oxygen uptake.

[0041] After calculating the runner's target heart rate zone, the host computer outputs control commands to the slave computer, which then executes the exercise prescription. Starting with the initial exercise intensity set on the treadmill, the system monitors the actual heart rate during exercise, adjusting the exercise intensity to maintain the actual heart rate within the target heart rate zone. The initial exercise intensity can be set by the system, for example, an incline of 0 and a speed of 1 kilometer per hour.

[0042] Adjusting exercise intensity is achieved by adjusting the treadmill's speed and incline. This adjustment can be done manually, automatically, or a combination of both. All three modes can coexist during a single run. In manual mode, the runner modifies incline and speed parameters directly through the user interface. In this mode, the runner can directly adjust these parameters without being restricted to a maximum speed value before changing the incline. In automatic mode, the treadmill system automatically adjusts the intensity. If the actual heart rate remains below the target heart rate zone for a first preset duration (e.g., 1 minute), the exercise intensity increases; if the actual heart rate remains above the target heart rate zone for a second preset duration (e.g., 1 minute), the exercise intensity decreases. Furthermore, the manual adjustment mode takes precedence over the automatic adjustment mode. For example, when the actual heart rate deviates from the target heart rate range for more than 1 minute, the host computer will issue a voice reminder. Within a set time, such as 1 minute, the speed and incline can be manually adjusted, or both can be adjusted simultaneously. If no manual adjustment instruction is received within 1 minute, the system will enter the automatic adjustment mode. However, if there is a manual adjustment within that 1 minute, the system will not enter the automatic adjustment mode.

[0043] In automatic adjustment mode, increasing exercise intensity follows a rule of first increasing speed and then increasing incline. Only when the speed is increased to maximum and still below the target heart rate zone will the incline be increased. Conversely, decreasing exercise intensity follows a rule of first decreasing incline and then decreasing speed. Only when the incline is decreased to 0 and still above the target heart rate zone will the speed be decreased.

[0044] The treadmill incline can be adjusted in increments of 1°, with a maximum incline set to 15 degrees. The treadmill speed can be adjusted as follows: below 4 km / h, increments of 2 km / h; between 4 and 7 km / h, increments of 1 km / h; and above 7 km / h, increments of 0.5 km / h, with a maximum speed set to 10 km / h.

[0045] For example: Runner A calculates the target heart rate zone as P1-P2 through steps S1 and S2. In step S3, the treadmill is started, and the exercise prescription is executed at the initial intensity set by the system (incline 0, speed 1 km / h). At this time, the actual heart rate is lower than P1, and the system issues a voice prompt reminding runner A to adjust the running belt speed and incline using a manual + automatic hybrid adjustment mode. Specifically, within one minute of the prompt, runner A manually modifies the speed parameters to 5 km / h and the incline to 2° on the interactive interface. The first exercise prescription is then continued, but the actual heart rate still does not reach P1-P2 for more than one preset time. After one minute, the system issues another voice prompt, reminding runner A that if no manual adjustment is made within one minute, the system will automatically adjust, increasing the speed by 1 to 6 kilometers per hour while maintaining the incline. Then, the runner continues according to the second exercise prescription. If the actual heart rate exceeds P2 for more than one minute beyond the second preset duration, the system issues another voice prompt, reminding runner A that if no manual adjustment is made within one minute, the system will automatically adjust, maintaining the speed while decreasing the incline by 1 to 1 degree. Then, the runner continues according to the third exercise prescription. If the actual heart rate remains between P1 and P2, and the speed and incline remain unchanged, then this third exercise prescription is the optimal exercise prescription for runner A. The duration of each exercise session is set based on runner A's daily exercise volume: 15 minutes for beginners, 20 minutes for occasional exercisers, 25 minutes for regular exercisers, 30 minutes for intermediate exercisers, and 40 minutes for competitors. One exercise prescription cycle is preset to 20 sessions.

[0046] In summary, the heart rate-based exercise training method of this embodiment includes the following steps: S1, acquiring the instantaneous heart rate data of the runner at the moment of completing the preset cardiorespiratory endurance test prescription, and calculating the maximum oxygen uptake by combining the instantaneous heart rate data with the runner's basic information; S2, obtaining the oxygen uptake percentage through the maximum oxygen uptake and oxygen uptake percentage comparison table, and calculating the target heart rate zone by combining the oxygen uptake percentage, gender, and age; S3, executing the exercise prescription based on the target heart rate zone in step S2 and acquiring the actual heart rate during the exercise. When the actual heart rate deviates from the target heart rate zone, the exercise intensity is adjusted to maintain the actual heart rate within the target heart rate zone.
