[0002] This application is filed with the World Intellectual Property Organization (WIPO) under the Patent Cooperation Treaty (PCT) and claims priority to U.S. Application Serial No. 18 / 670,094, filed May 21, 2024, which is a continuation-in-part (CIP) application of U.S. Application No. 18 / 605,240, filed March 14, 2024. Technical Field

[0003] This disclosure generally relates to a cardio-enhancing training device including an adjustable height component designed to adjust the height of armrests that are designed to support at least a portion of a user's weight. Furthermore, this disclosure relates to a method for automatically adjusting one or more operating settings of the cardio-enhancing training device. Background Technology

[0004] Cardiovascular training (also known as cardio or aerobic exercise) is beneficial for maintaining and improving heart health, circulation, weight management, lung health, and other physical and mental aspects. Some forms of cardiovascular training recommended by the American Heart Association include brisk walking, jogging, and running. Therefore, cardio-training devices are popular because they allow users to engage in cardio exercises indoors, regardless of weather, time of day, or location. Furthermore, cardio-training devices can cause less stress on the user's joints because they may include shock-absorbing or cushioning systems that reduce the impact on the user's joints compared to exercising outdoors on hard surfaces. Some common cardio-training devices include treadmills, elliptical trainers, and stair climbers.

[0005] However, running, jogging, and walking on a cardio-training machine can still cause joint damage because users are constantly shifting their weight and affecting their lower joints. Therefore, users may prematurely stop their workouts due to injury or to prevent further injury. In particular, inexperienced, older, and overweight users may face a higher risk of injury due to their physical limitations. However, if users are unable to complete their cardio workouts, it may be difficult to improve their health.

[0006] Therefore, some cardio support devices may include handrails positioned in front of and / or to the sides of the user, allowing them to grip the handrails for stability during exercise. This allows users to support some of their weight, thereby reducing stress on their lower joints. However, the handrails may not be adjustable. Consequently, the handrails may not be at the ideal height for various users, potentially making it difficult for them to support themselves on the cardio support device. Thus, even with the handrails, users may still end their workout prematurely to avoid joint pain.

[0007] Furthermore, if users don't maintain their heart rate within their target heart rate range, they may not reap some of the benefits of cardio exercise. A user's target heart rate range can be described as a fraction or percentage of their maximum heart rate. A user's maximum heart rate indicates their endurance for vigorous cardio exercise. Consistent cardio exercise can increase a user's maximum heart rate. Furthermore, consistent cardio exercise can lower a user's resting heart rate, which is an indicator of heart health. However, if users exercise too intensely, they may put excessive stress on their heart, potentially leading to cardiovascular damage. Conversely, if users exercise too lightly and don't raise their heart rate above their resting heart rate, they may not realize some of the benefits of cardio exercise. Therefore, it is beneficial for users to maintain their heart rate within their target heart rate range during exercise.

[0008] Therefore, some cardio training devices may include a heart rate monitor to track the user's heart rate during use. However, the heart rate monitor included in some cardio training devices may require the user to grasp or touch specific parts of the device. The user may not be able to properly access the heart rate monitor, or the monitor may malfunction. Consequently, users may find it difficult to measure their heart rate during exercise. Furthermore, even if a user can measure their heart rate, they may need to determine their target heart rate and adjust operating parameters on the cardio training device (such as speed settings) to maintain that target heart rate. Moreover, this is a process that users may need to repeat multiple times throughout their workout, as their heart rate may change as they progress. Therefore, a user's workout may be interrupted or hindered multiple times when they have to measure their heart rate and adjust operating parameters on the cardio training device.

[0009] Therefore, there is a need in the art for a cardio-training device that reduces the risk of injury to the user during use, enabling the user to complete their cardio-respiratory exercise. Furthermore, there is a need for a cardio-training device that automatically adjusts operating parameters according to the user's needs to reduce the chance of injury during cardio-respiratory exercise and ensure that the user achieves the physical benefits of cardio-respiratory exercise.

These drawings are not necessarily drawn to scale, depict selected embodiments, and are not intended to limit the scope of embodiments of the invention. Those skilled in the art will recognize that the examples provided herein have many useful alternatives and fall within the scope of embodiments of the invention.

[0054] Before explaining any embodiments of the invention in detail, it should be understood that the application of the invention is not limited to the construction details and component arrangements set forth in the following description or shown in the drawings. The invention can have other embodiments and can be practiced or implemented in various ways. Furthermore, it should be understood that the wording and terminology used herein are for descriptive purposes and should not be considered limiting. For example, the use of “comprising,” “including,” or “having,” and variations thereof, is intended to cover items listed below and their equivalents, as well as additional items.

[0055] like Figures 1 to 4 As shown, embodiments of this disclosure include a cardiac training device. This cardiac training device may be provided in the form of a treadmill. First, refer to... Figure 1 The image depicts a cardiac enhancement training device 100. The cardiac enhancement training device 100 may include an exercise platform 110 and a frame 120.

[0056] The exercise platform 110 may include a treadmill deck 112, a running belt 114, a motor 116, a shock absorption system 118, and a weight sensor 119. The treadmill deck 112 may be a generally flat surface designed to provide support for the running belt 114. The running belt 114 may be wound around the treadmill deck 112. A drive system (such as a roller and / or pulley system) may be designed to transmit rotational motion from the motor 116 to the running belt 114, causing the running belt 114 to move about the treadmill deck 112 in the z-direction. Therefore, a user can walk, jog, or run on the exercise platform 110 because the running belt 114 will move. As shown, the motor 116 is located near the front region of the exercise platform 110. However, the motor 116 may be located near the rear of the exercise platform 110 or located below the exercise platform 110. The shock absorption system 118 may be included in or below the treadmill deck 112. The shock absorption system 118 may be designed to absorb some of the impact of the user's steps to reduce stress on the user's joints. The weight sensor 119 may be located in or on the exercise platform 110. The weight sensor 119 may be designed to sense the weight of a user on the cardio-training device 100. For example, the weight sensor 119 may be located below the treadmill 114 so that it can sense the user's weight when the user is standing on the treadmill 112.

[0057] Frame 120 may include a lower base 130, support columns 140, and an upper base 150. Exercise platform 110 may be connected to the lower base 130. Therefore, the lower base 130 may be designed to provide support for exercise platform 110. Support columns 140 may be attached to the lower base 130 and are designed to support the upper base 150. As shown, support columns 140 include four support columns 141-144. However, it should be understood that the cardiac enhancement training device 100 may include more or fewer support columns 140.

[0058] The cardiac enhancement training device 100 may include a height adjustment assembly 145, which is designed to adjust the height "H" of at least a portion of the upper base 150 relative to the treadmill 112. In some instances, the height adjustment assembly 145 may be designed to modify the length of the support column 140 in the vertical or y-direction. Therefore, the height "H" of the upper base 150 can be adjusted by modifying the length of the support column 140, since the height of the upper base 150 can be based on the length of the support column 140.

[0059] As depicted, at least some portions of the support column 140 may be hollow. Therefore, each support column in the support column 140 may include a height adjustment assembly 145. In some instances, the height adjustment assembly 145 includes one or more springs. The pressure on the springs can be adjusted so that the springs are compressed or decompressed, thereby shortening or lengthening the springs. Thus, the height "H" of the upper base 150 can be adjusted based on the compression of the springs. In other instances, the height adjustment assembly 145 may include a hydraulic cylinder designed to raise or lower a piston, thereby increasing or decreasing the length of the support column 140.

[0060] The upper base 150 may include armrests 160 and a central control station 170. As shown, the cardiac enhancement training device 100 may include a first armrest 161 and a second armrest 162. However, it should be understood that the cardiac enhancement training device 100 may include more or fewer armrests 160. In some instances, the armrests 160 may include a contact heart rate sensor 164. The contact heart rate sensor 164 may be a contact heart rate sensor designed to sense the user's heart rate. In some instances, the user's heart rate may be detected by an external heart rate monitor. For example, the user may wear a heart rate monitoring device 180. The wearable heart rate monitoring device 180 may be a chest strap heart rate monitor, a wrist strap heart rate monitor, an arm strap heart rate monitor, or any other heart rate monitor known in the art. Data from the wearable heart rate monitoring device 180 may be received by the cardiac enhancement training device 100 via a receiver 172 included in the central control station 170.

[0061] The central control station 170 may further include a controller 174 designed to receive user data, interpret user data, and control one or more operational settings of the cardiac enhancement training device 100. User data may include the user's weight sensed by the weight sensor 119, the speed of the treadmill belt 114, the height "H" of the upper base 150 and / or handrail 160, and the user's heart rate sensed by the contact heart rate sensor 164 and / or wearable heart rate monitoring device 180. One or more operational settings may include the speed of the treadmill belt 114 and the height "H" of the upper base 150.

[0062] Now, for reference Figure 2The image shows a user 210 exercising on a cardio-strengthening device 100. As depicted, the user 210 is exercising on the cardio-strengthening device 100 and supporting themselves by resting their arms on a first handrail 161 (not shown) and a second handrail 162. Therefore, the user 210 can reduce some stress on their lower joints by supporting some of their weight with their upper body. Thus, the user 210 is likely less likely to injure themselves because their lower joints are likely to experience less stress due to the reduced weight applied to them. Furthermore, if the user 210 can prevent injury, they are likely more likely to complete their workout.

[0063] As shown in the figure, if the armrests 160 of the upper base 150 are at a height at which the user 210 can extend their arms in a roughly straight line “S”, then the user 210 can more easily support some of their weight. However, not all users have the same height. Therefore, adjusting the height “H” of the upper base 150 can be beneficial so that different users can support themselves with roughly straight arms, regardless of the user's height.

[0064] Next reference Figure 3 and Figure 4 The text describes a cardiac enhancement training device 300. It mentions that the cardiac enhancement training device 300 is similar to... Figure 1 and Figure 2 The cardiac enhancement training device 100. However, the frame 320 can be different (e.g., compared to...). Figure 1 (Frame 120). Specifically, the number of support columns, upper base, and height adjustment components in frame 320 can vary.

[0065] As shown in the figure, the cardiac enhancement training device 300 includes a support column 340, comprising a first support column 341 and a second support column 342. In some embodiments, the support column 340 is a fixed column. Therefore, the length of the support column 340 in the y-direction can be invariable.

[0066] Similar to Figure 1 The upper base 150 and upper base 350 may include armrests 360. Here, the upper base 350 may include four armrests 361-364. The first lower armrest 361 and the second lower armrest 362 may be oriented such that they are approximately parallel to the exercise platform 110. Therefore, similar to... Figure 2The user 210 can support themselves on the first lower armrest 361 and the second lower armrest 362, thus relieving some pressure on their lower joints. Further, the upper base 350 may include a first upper armrest 363 and a second upper armrest 364. The first upper armrest 363 and the second upper armrest 364 may be oriented at an angle of approximately 60° to approximately 120° relative to each of the first lower armrest 361 and the second lower armrest 362. The first upper armrest 363 and the second upper armrest 364 may provide additional contact points for the user to grip during exercise. Further, similar to armrest 160, each armrest in armrest 360 may include a contact-type heart rate sensor 164.

[0067] As discussed above, adjusting the height "H" of at least a portion of the upper base 350 can be beneficial, allowing users to support themselves during exercise. In particular, adjusting the height of the handrail 360 can be helpful, as the handrail 360 can be designed for the user to grip. Therefore, the height adjustment component 345 can be designed to adjust the height "H" of the handrail 360 of the upper base 350, regardless of the height of the support column 340.

[0068] like Figure 3 As best shown, in some instances, the height adjustment assembly 345 can be designed to adjust the height "H" of the entire upper base 350 (i.e., the central control station 170 and the handrail 360). The height adjustment assembly 345 may include a sliding seat, such as a slide rail or track, which allows the upper base 350 to slide up and down along the length of the support column 340 in the y-direction.

[0069] On the contrary, such as Figure 4 As shown, in other instances, the height adjustment assembly 345 can be designed to adjust the height "H" of the handrail 360 without changing the height of the central control station 170. As depicted, the height of the first lower handrail 361 and the second lower handrail 362 can be adjusted from a first height "H1" to a second height "H2". In some instances, the height adjustment assembly 345 can be provided in the form of one or more springs located in or connected to the first lower handrail 361 and the second lower handrail 362. Thus, when a user leans on the first lower handrail 361 and the second lower handrail 362, the springs can be compressed, thereby adjusting the height of the first lower handrail 361 and the second lower handrail 362 from the first height "H1" to the second height "H2". In other instances, the height adjustment assembly 345 may include a sliding seat that allows the first lower handrail 361 and the second lower handrail 362 to slide upward and downward along the length of the support post 340 in the y-direction.

[0070] In addition to adjusting the height “H” of the handrails 360 and / or the upper base 350, adjusting the speed of the treadmill belt 114 of the cardio-training devices 100 and 300 can be beneficial. As mentioned above, it can be beneficial for users to maintain their heart rate within a target heart rate range. However, users may find it difficult to continuously monitor their heart rate, determine whether they are within their target heart rate range, and adjust one or more operating parameters of the cardio-training device accordingly. For example, both the speed of the treadmill belt and the height of the handrails 360 and / or the upper base 350 can affect the user's heart rate. At higher treadmill belt speeds, the user's heart rate may increase. Similarly, if the user supports their weight without the assistance of the handrails, the user's heart rate may increase. Therefore, this paper discloses a method for analyzing multiple user inputs and controlling the cardio-training device based on those inputs.

[0071] refer to Figure 5 The image shows user 510 on the cardiac enhancement training device 500. The cardiac enhancement training device 500 is similar to... Figure 1 and Figure 2 Heart Enhancement Training Device 100 and Figure 3 and Figure 4 The cardiac enhancement training device 300. However, the cardiac enhancement training device 500 may include different frames 520 (e.g., as compared to...). Figure 1 and Figure 2 Frame 120 and Figure 3 and Figure 4 (Frame 320). Specifically, frame 520 may include an anti-gravity support system 530 and a height adjustment system 540.

[0072] Frame 520 may include a first lateral support frame 521 and a second lateral support frame 522. The first lateral support frame 521 and the second lateral support frame 522 may be connected via one or more crossbeams (not shown). For example, frame 520 may include a bottom crossbeam designed to be positioned below the exercise platform 110 and connected to each of the first lateral support frame 521 and the second lateral support frame 522. Alternatively or additionally, frame 520 may include a top crossbeam designed to be positioned above the exercise platform 110 and above the vertical height of the user 510, and connected to each of the first lateral support frame 521 and the second lateral support frame 522. Thus, the bottom crossbeam and / or the top crossbeam can provide stability to frame 520.

[0073] The first lateral support frame 521 and the second lateral support frame 522 may be mirror images of each other. Therefore, for the sake of brevity, only the first lateral support frame 521 will be described in detail. However, it should be understood that the second lateral support frame 522 may include similar features.

[0074] As shown in the figure, the first lateral support frame 521 may include a first vertical portion 551 and a second vertical portion 552 generally parallel to the first vertical portion 551. The frame 520 may further include a first horizontal portion 561 and a second horizontal portion 562 generally parallel to the first horizontal portion 561. Each of the first horizontal portion 561 and the second horizontal portion 562 may be positioned at approximately a 90° angle to the first vertical portion 551 and the second vertical portion 552. The first vertical portion 551, the second vertical portion 552, the first horizontal portion 561, and the second horizontal portion 562 may be connected together to form a generally rectangular shape.

[0075] Furthermore, in some instances, the first lateral support frame 521 may include various crossbeams (e.g., additional crossbeams from the top and bottom crossbeams mentioned above). As shown, the first lateral support frame 521 may include a vertical crossbeam 570 connected to the first horizontal portion 561 and the second horizontal portion 562, and positioned between and generally parallel to the first and second vertical portions 551 and 552. The first lateral support frame 521 may further include a first horizontal crossbeam 571 connected to the first vertical portion 551 and the vertical crossbeam 570 and positioned generally parallel to the first horizontal portion 561 and / or the second horizontal portion 562. In still other instances, the first lateral support frame 521 may include a second horizontal crossbeam 572.

[0076] The advantage of frame 520 is that, in some instances, frame 520 can be separate from the rest of the cardio-training device 500 (e.g., exercise platform 110, treadmill 112, running belt 114, motor 116, shock absorption system 118, and weight sensor 119). For example, frame 520 can be attached to or combined with an exercise device (such as a treadmill or elliptical trainer) that does not include an adjustable height component and / or anti-gravity support system. Therefore, the advantage of frame 520 is that it can be easily installed on cardio-training devices that a user may already own. Thus, a user can utilize frame 520 to enhance the safety of an existing cardio-training device without purchasing a completely new one. However, in other instances, frame 520 can be integrated with the rest of the cardio-training device 500 (e.g., non-removable). Therefore, cardio-training device 500 can be provided as an integrated system (e.g., a system including an exercise device (such as a treadmill or elliptical trainer), an anti-gravity support system, and a height adjustment system).

[0077] The features of the antigravity support system 530 will now be described. As shown and discussed below, the antigravity support system 530 can be designed to relieve pressure on the user's lower joint by providing lifting or antigravity force to the user 510. The antigravity support system 530 may include one or more antigravity strips 532. As shown in one example, the antigravity support system 530 may include two antigravity strips 532. A first antigravity strip may be connected to a first lateral support frame 521, and a second antigravity strip may be connected to a second lateral support frame 522. Referring only to the first lateral support frame 521, it can be seen that the antigravity strips 532 may be connected to the vertical crossbeam 570 near the first horizontal portion 561. However, it should be understood that the antigravity strips 532 may be connected to any portion of the first lateral support frame 521.

[0078] The antigravity strip 532 can be an elastic band, such as an elastic cord or resistance band, which is designed to support a predetermined amount of weight. In some instances, the antigravity strip 532 can support at least 5 pounds, at least 10 pounds, at least 20 pounds, at least 30 pounds, at least 40 pounds, at least 50 pounds, or at least 75 pounds, or at least 100 pounds.

[0079] During operation of the cardiac enhancement training device 500, the user 510 can attach the antigravity strap 532 to themselves. Therefore, the antigravity strap 532 can provide a lifting force approximately equal to the amount of weight that the antigravity strap 532 is designed to support. Thus, the amount of weight supported by the antigravity strap 532 can be relieved from the user 510, which can make it easier for the user 510 to exercise because the weight on the user 510's joints may be smaller.

[0080] like Figure 6 Ideally, user 510 can attach the antigravity strap 532 to their waist area. In some instances, the antigravity strap 532 may include clips, hooks, belts, or other attachment mechanisms designed to attach to the user's clothing or body. For example, user 510 can attach the antigravity strap 532 to a belt loop on their clothing. In another example, user 510 can fasten a belt to their waist and attach the antigravity strap 532 to their waist. In yet another example, user 510 may wear special clothing designed to work in conjunction with the antigravity strap (i.e., clothing including attachment points for the antigravity strap).

[0081] The benefit of the anti-gravity support system 530 is that, in addition to relieving pressure on the joints of the user 510, the user 510 is less likely to injure themselves because the anti-gravity straps 532 prevent the user 510 from falling. Another benefit of the anti-gravity straps 532 is that the user's hands can remain free because the user 510 may not need to grip the anti-gravity straps 532. Therefore, the user 510 can use their hands for other purposes, such as holding onto the handrails. Thus, the cardiac training device 500 may include a height adjustment system 540 with one or more handrails.

[0082] Re-reference Figure 5 As can be seen, the two handrails 580 can be included in or attached to the frame 520 (e.g., a first handrail corresponding to the first lateral support frame 521 and a second handrail corresponding to the second lateral support frame 522). The first and second handrails can be similar. Therefore, for the sake of simplicity, the first and second handrails will be referred to as "handrail 580". Similar to... Figure 1 and Figure 2 The handrail 160 and Figure 3 and Figure 4 The height "H" of the handrails 360 and 580 can be adjusted via the height adjustment system 540.

[0083] The height adjustment system 540 may include one or more vertical posts 542. An armrest 580 may be attached to one or more vertical posts 542. Furthermore, the armrest 580 may be designed to slide up and down along one or more vertical posts 542 in the y-direction. Therefore, to adjust the height "H" of the armrest 580, the user 510 may apply a downward force to the armrest 580 in the y-direction.

[0084] In some aspects, the handrail 580 may be attached to a sleeve or sliding track 544, which is attached to or is part of one or more vertical posts 542. The one or more vertical posts 542 may be stationary posts, and the sliding track 544 may be designed to move up or down along the one or more vertical posts 542 in the y-direction. Therefore, the height “H” of the handrail 580 can be adjusted based on the position of the sliding track 544. In some instances, the position of the sliding track 544 may be adjusted via a spring system or a pneumatic system, as described above. In other instances, the position of the sliding track 544 may be adjusted via a belt system 546.

[0085] The belt system 546 may include one or more belts designed to provide tension to the sliding track 544. In some instances, the one or more belts may support at least 5 pounds, at least 10 pounds, at least 20 pounds, at least 30 pounds, at least 40 pounds, or at least 50 pounds.

[0086] As shown in one example, the belt system 546 may include a first stud 547 and a second stud 548. The first stud 547 may be attached to a first horizontal crossbeam 571. The second stud 548 may be attached to a sliding track 544. The one or more belts may be stretched over and between the first stud 547 and the second stud 548. Thus, when a user 510 applies a downward force to the armrest 580 and, consequently, to the sliding track 544 (including the second stud 548), the belts of the belt system 546 may stretch. When a similar downward pressure is applied, a belt capable of supporting a lower amount of weight (e.g., 5 pounds) may stretch more than a belt designed to support a larger amount of weight (e.g., 20 pounds). Therefore, the user 510 can customize the weight supported by the armrest 580 by adjusting the belt. For example, if the user 510 needs to relieve approximately 20 pounds of weight from their lower joint, the user 510 may use a belt designed to support 20 pounds.

[0087] Therefore, similar to the systems and methods described above, in some instances, the cardiac enhancement training device 500 can be designed to assist user 510 in determining how much weight they need to reduce from their joints. For example, as described above, user 510 can input their health information into a controller included in the cardiac enhancement training device 500 (e.g., Figure 1 In the controller 174, the controller can recommend the amount of weight to be reduced from the user 510. The controller can then be designed to determine which combination of systems to use. For example, if the user 510 needs to reduce approximately 20 pounds from their lower joints, the controller can determine that using the antigravity support system 530 can reduce approximately 10 pounds and using the height-adjustable handrail 580 can reduce approximately 10 pounds. Furthermore, in some instances, the controller can be designed to automatically adjust one or more systems of the cardiac training device 500 (e.g., the antigravity support system 530 and the height-adjustable handrail 540) to meet the user's needs.

[0088] Go to Figure 7 This document illustrates a method for controlling one or more operating parameters of a cardiac enhancement training device according to embodiments disclosed herein. Method 700 can be used... Figure 1 and Figure 2 Heart Enhancement Training Device 100 and Figure 3 and Figure 4 The 300-unit heart-strengthening training device is used for implementation.

[0089] In step 710, the controller 174 can be designed to determine multiple user inputs. These multiple user inputs can be determined before the user begins the fitness program. These user inputs may include the user's height, age, resting heart rate, maximum heart rate, exercise intensity, weight, and lower joint weight thresholds, etc.

[0090] Users can enter one or more user inputs from a plurality of user inputs into an interface included in central control station 170. For example, central control station 170 may include an interface in the form of a touchscreen where users can enter data. In some instances, controller 174 may be designed to prompt users to enter user input before starting a workout. For example, users can select and enter their height and age on the interface.

[0091] Alternatively or additionally, the controller 174 may be designed to use the weight sensor 119, the contact heart rate sensor 164, and / or the wearable heart rate monitoring device 180 to determine one or more user inputs among a plurality of user inputs.

[0092] For example, when a user steps on a cardio exercise device, the user's weight can be determined by the weight sensor 119. The threshold weight can be a weight determined and entered by the user. Alternatively, the threshold weight can be determined by the controller 174. For example, the controller 174 can determine the user's weight via the weight sensor 119 and then determine the percentage of the sensed weight that the user's joints can withstand. The percentage of the sensed weight that the user's joints can withstand can be based on various user data inputs, such as the user's age, fitness level, weight, exercise intensity, etc.

[0093] The user's resting heart rate can be determined and recorded by the user. Alternatively, the controller 174 can determine the user's resting heart rate by sensing the user's heart rate via a contact heart rate sensor 164 and / or a wearable heart rate monitoring device 180 before the user begins their workout.

[0094] Exercise intensity can be selected by the user and can be determined by influencing the user's target heart rate to determine how intense the workout will be. Exercise intensity can include various intensity settings, such as low, moderate, high, and very high. Exercise intensity can be a percentage selected by the user. For example, a low intensity setting can be approximately 60% to approximately 69%, a moderate intensity setting can be approximately 70% to approximately 79%, a high intensity setting can be approximately 80% to approximately 89%, and a very high intensity setting can be approximately 90% to approximately 100%.

[0095] In step 730, the controller 174 may be configured to determine the user's target heart rate range. The user's target heart rate may be based on at least one of a plurality of user inputs. The user's target heart rate range may be a target heart rate plus / minus threshold. The threshold may be a percentage, such as + / - 10%. Alternatively, the threshold may be beats per minute (bpm), such as + / - 10 bpm.

[0096] A user's target heart rate can be determined using formula I.

[0097] Target heart rate = Heart rate reserve x Exercise intensity + Resting heart rate

[0098] Formula I

[0099] The user's heart rate reserve can be determined using Formula II.

[0100] Heart rate reserve = maximum heart rate - resting heart rate

[0101] Formula II

[0102] The user's maximum heart rate can be manually entered by the user in step 710. Alternatively, the user's maximum heart rate can be determined using Formula III.

[0103] Maximum heart rate = 220 - user's age

[0104] Formula III

[0105] In step 730, the controller 174 can be configured to determine initial operating settings for the cardio training device or the user during a fitness program. The initial operating settings can be based on at least one of a plurality of user inputs. The initial operating settings may include an initial height setting and / or an initial speed for the treadmill belt 114. The initial height setting may be… Figures 1 to 4 The height "H".

[0106] The height setting can be based on one or more user inputs. For example, a user can enter their height via an input screen, and the controller 174 can be designed to determine the optimal height "H" for the user based on the entered height. Furthermore, the controller 174 can be designed to determine the optimal height "H" based on the user's lower joint threshold weight. Furthermore, the controller 174 can be designed to prompt the user to change the treadmill belt height "H" and / or speed when necessary.

[0107] As described above, the cardiac enhancement training device disclosed herein may include various height-adjustable components, such as Figure 1 and Figure 2 Height adjustment component 145 and Figure 3 and Figure 4The height adjustment component 345. Therefore, in some instances, the height setting can be adjusted manually (e.g., by a spring system). Alternatively, in some instances, the height setting can be adjusted via a controller 174 (e.g., by an automated piston system).

[0108] The initial speed setting can be based on one or more user inputs from a plurality of user inputs. For example, controller 174 can be designed to determine the initial speed based on the user's target heart rate range. Furthermore, controller 174 can be designed to instruct the user to set the speed of treadmill belt 114 to the initial speed, or controller 174 can be designed to automatically adjust the speed of treadmill belt 114 to the initial speed once the user begins their fitness program.

[0109] After the user begins their fitness program, in step 740, the controller 174 can be designed to determine the user's heart rate. The controller 174 can determine the user's heart rate based on the heart rate sensed by the contact heart rate sensor 164 and / or the wearable heart rate monitoring device 180. Therefore, in some instances, a two-layer structure can be used to determine the user's heart rate to ensure a clear count of the user's pulse. Using two heart rate monitors (e.g., the contact heart rate sensor 164 and the wearable heart rate monitoring device 180) can be advantageous because the user may not always maintain contact with the contact heart rate sensor 164, or one heart rate sensor may malfunction. The controller 174 may also include a filtering device designed to remove noise from the sensed heart rate. Furthermore, the controller 174 may include an amplifier designed to amplify the signals received from the contact heart rate sensor 164 and the wearable heart rate monitoring device 180.

[0110] In step 750, the controller 174 may be designed to determine whether the user's sensed heart rate is within the user's target heart rate range.

[0111] If, in step 750, the controller 174 determines that the user's sensed heart rate is within the target heart rate range, the method proceeds to step 760. In step 760, the controller 174 may be configured to maintain one or more operating settings of the cardiac enhancement training device. These one or more operating settings may include a speed setting (e.g., the speed of the treadmill belt 114) and a height "H" setting for the upper base and / or handrails.

[0112] However, if in step 750, the controller 174 determines that the user's sensed heart rate is not within the target heart rate range, the method proceeds to step 770. In step 770, the controller 174 may be configured to change one or more operating settings of the cardio-enhancing training device. For example, if the user's sensed heart rate is higher or lower than the target heart rate range, the controller 174 may be configured to change the height "H" of the upper base and / or handrails or instruct the user to change the height of the upper base and / or handrails. If the upper base and / or handrails are not at the correct height, the user may find it more difficult to support themselves. Therefore, the user's heart rate may increase as the user exercises themselves.

[0113] In some respects, the controller can also be designed to alter or recommend that the user alter the anti-gravity support system (e.g., Figure 5 and Figure 6 Features of the antigravity support system 530. For example, the controller can instruct the user to adjust the antigravity support system so that it can support more of the user's weight, thereby reducing the weight on the user's lower joints.

[0114] In some instances, if the user's heart rate is above the target heart rate range, the controller 174 can decrease the speed setting by reducing the power of the motor 116. The controller 174 can also be configured to instruct the user to manually decrease the speed setting by selecting the speed on the central control station 170. Conversely, if the user's heart rate is below the target heart rate range, the controller 174 can be designed to automatically increase the speed setting by increasing the power of the motor 116 or to instruct the user to increase the speed setting. In some instances, the controller 174 can be designed to increase or decrease the speed setting by a threshold amount, such as + / - 10% of the treadmill belt 114 speed. However, it should be understood that the threshold amount can be any value.

[0115] After steps 760 and 770, the method can return to step 740 and continue monitoring the user's heart rate until the user completes their workout. Therefore, steps 740-770 can be repeated multiple times throughout the user's workout. This makes it more likely that the user will complete their workout without prematurely stopping or injuring themselves, as method 700 helps keep the user's heart rate within the desired range. Therefore, the system and method described herein can be more beneficial than conventional cardio training systems and methods.
