Description

Technical Field

[0001] The present invention relates to an exercise device and a method of using the same, and more particularly to a muscle strength training device and a training method thereof. Background Art

[0002] Strength training is very helpful for maintaining personal fitness and good health. Especially after the age of 40, the muscle mass of adults loses 8% every 10 years on average. If ordinary people want to gain muscle through fitness or weight training, in addition to spending money to hire a coach for professional guidance, they can only spend time learning by themselves.

[0003] However, in the absence of professional planning, it is not possible to adjust the exercise menu according to past records and current physical condition to improve exercise results. If the exercise intensity of the training is too low, it will not achieve the desired exercise effect; and if the exercise intensity is too high, it may cause muscle overwork and fail to increase muscle strength, and may cause sports injuries. In addition, even if a coach is hired for guidance, if the trainee does not train according to the guidance, sports injuries may occur.

[0004] Therefore, it is necessary to provide an advanced muscle strength training device and a training method thereof to solve the problems faced by the prior art. Summary of the invention

[0005] One embodiment of the present specification discloses a muscle training device for training at least one muscle of an operator, comprising: an actuator, a first resistor, a first pull rope, and a resistance controller. The actuator is used to contact the operator so that the muscle applies multiple mechanical forces to it. The first resistor provides multiple training resistances opposite to the mechanical forces. The first pull rope connects the first resistor and the actuator to transmit multiple mechanical forces to the first resistor to respectively counteract multiple training resistances. The resistance controller is used to measure multiple rope speeds of the pull rope, and according to the multiple rope speeds, the resistance is superimposed or reduced in stages so that the maximum mechanical force is substantially equal to the maximum training resistance.

[0006] Another embodiment of the present specification discloses a muscle strength training method for training at least one muscle of an operator, comprising: providing a muscle strength training device, which comprises: an actuator, a resistor, a pull rope connecting a first resistor and the actuator, and a resistance controller. Using the resistance controller to test the maximum strength of the muscle comprises the following steps: setting the initial resistance (FS) of the resistor and outputting it through the pull rope; using the muscle to pull the pull rope through the actuator; performing at least one rope speed detection by the resistance controller to obtain the real-time rope speed (S) of the pull rope; when the real-time rope speed is greater than the first preset rope speed (S>S1), the resistance controller superimposes the initial resistance value with the first preset resistance value (F1) in stages (n>1), and notifies the resistor to output it through the pull rope, and then repeats the rope speed detection at least once; and when the real-time rope speed is less than or equal to the first preset rope speed (S≦S1), determining the sum (FS+n×F1) of the initial resistance value (FS) and the superimposed first preset resistance value (n×F1) as the maximum strength of the muscle (Fm=FS+n×F1).

[0007] According to the above embodiments, this specification provides a muscle strength training device and a training method thereof, which uses a pull rope to connect an actuator and a resistor, so that the mechanical force applied by the operator to the actuator counteracts the reverse training resistance provided by the resistor. The displacement rope speed of the pull rope during the training process is measured by a resistance controller. At the beginning of the training, the resistor outputs a pre-set initial resistance with a small value, and according to the rope speed, the training resistance is superimposed in stages in order to find the maximum strength of the operator's muscles in real time, and limit the subsequent training resistance output by the resistor to be substantially less than or equal to the maximum strength of the operator's muscles. In the later stage of training, by performing exhaustion training, the operator's output can be evaluated in real time according to the measured rope speed, and the resistor is notified to adjust the output training resistance accordingly, thereby reducing sports injuries caused by excessive exercise intensity during training, and achieving the purpose of strengthening muscle strength for designated parts.

[0053] This specification provides a muscle strength training device and a training method thereof, which can judge the maximum strength of the trainee's muscles in real time, and adjust the output resistance accordingly according to the trainee's output, thereby reducing sports injuries caused by improper use of force and achieving the purpose of strengthening muscle strength at designated parts. In order to make the above embodiments and other purposes, features and advantages of this specification more clearly understandable, the following specifically cites multiple embodiments and describes them in detail with the accompanying drawings.

[0054] Please refer to Figure 1A , Figure 1A It is a schematic diagram of the structure and operation of a muscle training device 10 according to an embodiment of the present specification. The muscle training device 10 is used to train at least one muscle of an operator 11, and includes: an actuator 100, a resistor 110, a pull rope 120, and a resistance controller 130. The actuator 100 is used to contact the operator 11 so that at least one muscle of the operator 11 can apply multiple mechanical forces FM to it. The resistor 110 provides multiple resistances FR opposite to the mechanical forces FM. The pull rope 120 connects the resistor 110 and the actuator 100, and transmits the multiple mechanical forces FM to the resistor 110, so that the multiple mechanical forces FM respectively counteract the multiple training resistances FR.

[0055] In some embodiments of the present specification, the actuator 100 may be a sports platform, which includes at least one mechanical structure or equipment that allows the operator 11, such as hands, feet, waist, head, etc., to be inserted therein to perform sports training. The operator 11 can provide mechanical stress FM by contracting or stretching the muscles to be trained, so as to pull, push or rotate the actuator 100, and transmit the mechanical stress FM to the resistor 110 through the pull rope 120.

[0056] For example, in the present embodiment, the actuator 100 may be a fitness puller, which includes a triangular ring push rod 101 and a pedal 102. The resistor 110 is connected to the pedal 102, one end of the pull rope 120 is connected to the resistor 110, and the other end is connected to the triangular push-pull ring 101, allowing the operator 11 to pass both hands therethrough. During the exercise operation, the operator 11 can stand on the pedal 102, and use the arm muscles to provide mechanical stress FM, and pull the triangular push-pull ring 101 and the pull rope 120 upward to perform exercise training. The resistor 110 includes a motor 110M (for example, a brushless DC motor), and one end of the pull rope 120 is connected to the motor, thereby generating a reverse rotating mechanical impedance (resistance FR) to counteract the mechanical stress FM. In detail, the resistance controller 130 is electrically connected to the resistor 110, and is used to adjust the resistance FR output by the resistor 110 according to the speed (rope speed) of the pull rope 120. For example, please refer to Figure 1B , Figure 1B is based on Figure 1A The illustrated diagram is a schematic diagram of the structural connection and functional control relationship between the resistance device 110 and the resistance controller 130. In this embodiment, the resistance device 110 includes a motor 110M and a reel 110R, one end of the pull rope 120 is wound around the reel 110R, and the rotation of the motor 110M can drive the reel 110R to rotate and drive the pull rope 120 to be pulled outward or reeled inward.

[0057] The resistance controller 130 includes a motor control board 130A, a system control board 130B and a speed (rope speed) detector 130C which are electrically or telephonically connected to each other. The speed (rope speed) detector 130C is adjacent to the reel 110R, and can detect the rotation of the reel 110R, and obtain the speed (rope speed) of the pull rope 120 being pulled out or reeled in through logical operations.

[0058] When the operator 11 performs exercise training and provides mechanical stress FM to pull the rope 120 outward, the resistance controller 130 detects the speed of the rope 120 (rope speed) in real time, and sends instructions to the motor control board 130A based on the detected speed of the rope 120 (rope speed), so as to adjust the three-phase voltage (not shown) output to the motor 110M in real time, so that the motor 110M provides multiple reverse torques opposite to the rotation direction of the reel 110R, thereby providing the rope 120 with multiple resistances FR to counteract the mechanical stress FM.

[0059] In addition, the muscle training device 10 further includes a wireless communication device (eg, a Bluetooth device) 140 disposed on a system control board 130B (eg, Figure 1B As shown in the figure, but not limited to this), it is used to communicate with the operator's 11 portable electronic product (for example, a smart phone, a laptop computer, a tablet computer, or other electronic wearable device, etc.) 12 to store historical data including mechanical force FM and resistance FR, rope pulling speed (rope speed), etc., and / or to set or modify these historical data.

[0060] However, the structure of the muscle training device 20 is not limited thereto. Figure 2 , Figure 2 2 is a schematic diagram of the structure and operation of another muscle training device 20 according to another embodiment of the present specification. The difference between the structure of the muscle training device 20 and the muscle training device 10 is that the actuator 200 of the muscle training device 20 is a multifunctional weight training platform, and the muscle training device 20 also includes another resistance 210 and another pull rope 220 used in conjunction with the actuator 100.

[0061] In this embodiment, the actuator 200 of the muscle training device 20 includes a pull rod 201 and a weight training platform 202. The resistors 110 and 210 are arranged in the weight training platform 202, and one end of the pull ropes 120 and 220 are respectively connected to the resistors 110 and 210, and the other end of the pull ropes 120 and 220 are connected to the two ends of the pull rod 201. During the exercise operation, the operator 11 can stand on the weight training platform 202, hold the pull rod 201 with both hands, and use the arm muscles to provide mechanical stress FM to pull the pull rod 201 and the pull ropes 120 and 220 upward to perform exercise training. In other words, through the connection of the pull rod 201 and the pull ropes 120 and 220, the resistors 110 and 210 are in parallel, and jointly provide a resistance FR in the opposite direction of the mechanical stress FM to perform exercise training.

[0062] By using the resistance controller 130 of the muscle strength training devices 10 and 20, the rope speed of the pull rope 120 (and the pull rope 220) can be measured, and according to the rope speed measured each time, the resistance can be added in stages to test the maximum muscle strength of the operator 11; or according to the rope speed measured each time, the resistance can be reduced in stages to perform exhaustion training.

[0063] For example, please refer to Figure 3 ,like Figure 3 As shown, the method for testing the maximum muscle strength of the operator 11 includes the following steps: First, as in step S301: the initial resistance (FS) of the resistor 110 (e.g., of the muscle strength training device 10) is set and output through the pull rope (e.g., the pull rope 120). The operator 11 can estimate and set a suitable initial resistance (FS) according to his own physical condition, the muscle part to be trained and the past training experience, and input it into the resistance controller 130 of the muscle strength training device 10.

[0064] As described in step S302, the muscles of the operator 11 provide mechanical force FM through the actuator 100 to pull the pull rope 120. At the same time, the resistance controller 130 notifies the resistance device 110 to output an initial resistance (FS) through the pull rope 120 to counteract the mechanical force FM of the muscles. As described in step S303, the resistance controller 130 performs rope speed detection to obtain the real-time rope speed (S) of the pull rope 120. As described in step S304, the real-time rope speed (S) is determined.

[0065] When the real-time rope speed is greater than the first preset rope speed (S>S1), for example, the first preset rope speed (S1) is the speed at which the acceleration of the pull rope 120 is 0, the initial resistance (FS) output by the resistor 110 through the pull rope 120 is obviously still less than the mechanical force FM provided by the muscles of the operator 11 through the actuator 100. As described in step S305: the resistance controller 130 adds a first preset resistance value (F1) to the initial resistance value in stages (n>1), and notifies the resistor 110 to output through the pull rope 120. Then repeat steps S303 and S304 and perform another rope speed detection and determine the real-time rope speed (S).

[0066] In some embodiments, the first preset resistance value (F1) can be set to be superimposed by 0.2 kg to 0.5 kg each time. After each superposition of the first preset resistance value (F1), the resistance (F) output by the motor of the resistor 110 is equal to the sum of the product of the initial resistance value and the default value and the moving average of the pull rope 120 (L / dL) (F=FS+F1×L / dL), where L is the stretched length of the pull rope 120 at that time; dL is the instantaneous stretched length of the pull rope 120.

[0067] When the real-time rope speed is less than or equal to the first preset rope speed (S≦S1), the resistance value F output by the resistance device 110 through the pull rope 120 is obviously substantially greater than or equal to the mechanical force FM provided by the muscles of the operator 11 through the actuator 100. At this time, as described in step S306: the sum (FS+n×F1) of the initial resistance value (FS) and the superimposed first preset resistance value (n×F1) is determined to be the maximum muscle strength (Fm=FS+n×F1).

[0068] In some embodiments, the first preset rope speed (S1) can be appropriately reduced so that the acceleration of the pull rope 120 at this rope speed is not 0. In this way, the resistance value F output by the resistor 110 through the pull rope 120 can be controlled to be substantially equal to the mechanical force FM provided by the muscles of the operator 11 through the actuator 100.

[0069] After determining the maximum muscle strength Fm of the operator 11, the resistance F subsequently output by the muscle strength training device 10 is all less than the maximum muscle strength Fm of the operator 11. Therefore, the operator 11 will not have excessive exercise intensity during subsequent training, causing muscle fatigue and sports injuries.

[0070] In addition, in the present embodiment, the method for testing the maximum muscle strength of the operator 11 also includes step S307: providing historical data D3 including the personal information of the operator 11, real-time rope speed (S), initial resistance (FS), first preset rope speed (S1), maximum strength (Fm), and first preset resistance value (F1) to the wireless communication device 140 built into the muscle strength training device 10, and telecommunication connecting with the portable electronic product (smart phone) 12 of the operator 11, so as to store and / or set and / or modify the historical data D3 and / or actively upload the historical data D3 to the cloud or computing platform (not shown) to provide the application program for subsequent computing and provide other service functions.

[0071] For example, in some embodiments, when the number of times that the instantaneous stretch lengths of the two pull ropes 120 and 220 of the muscle training device 20 are inconsistent exceeds a set value, the cloud or computing platform will provide reference data for exhaustion training based on the uploaded historical data D3, or issue a real-time warning to remind the operator 11 that the exercise posture may be incorrect. In other embodiments, when the historical data D3 shows that the instantaneous stretch length of the pull rope 120 is gradually decreasing, the application of the cloud or computing platform will automatically record the uploaded historical data and provide it to the operator 11 as a computing reference parameter for exhaustion training.

[0072] Please refer to Figure 4 , Figure 4 1 is a flowchart of a method for performing exhaustion training according to an embodiment of the present specification. The method for performing exhaustion training includes the following steps: First, as described in step S401, the resistance controller 130 controls the resistor 110 to output an initial training resistance with a maximum intensity (Fm) through the pull rope 120. And as described in step S402, the muscle is used to pull the pull rope 120 through the actuator 100 to perform muscle training.

[0073] At the same time, as described in step S403: the resistance controller 130 is used to detect the rope speed, and the real-time rope speed (S) of the pull rope 120 is obtained. And as described in step S404: the real-time rope speed (S) is determined. When the real-time rope speed is greater than the second preset rope speed (S>S2), the muscle training described in step S402 is continued, and steps S403 and S404 are repeated to perform rope speed detection and determine the real-time rope speed (S) again.

[0074] For example, in some embodiments of the present specification, the second preset rope speed (S2) may be the speed at which the acceleration of the pulling rope 120 is 0. When the real-time rope speed is less than the second preset rope speed (S < S2), the resistance output by the resistance device 110 through the pulling rope 120 is substantially equal to or slightly less than the muscle strength of the operator 11 at that time. At this time, as described in step S405: use the resistance controller 130 to gradually subtract a second preset resistance value (F2) from the maximum strength (Fm) of the initial training resistance in stages (k > 1), and control the resistance device 110 to output a degraded training resistance (F- = Fm - k × F2) through the pulling rope 120. And continue the muscle training described in step S402, and repeat steps S403 and S404 to perform a rope speed detection and judgment on the rope speed (S) again. In some embodiments of the present specification, the second preset resistance value (F2) can be set to decrease by 0.2 kg to 0.5 kg each time.

[0075] When the real-time rope speed (S) is greater than the third preset rope speed (S > Se), continue the muscle training described in step S402, and repeat steps S403 and S404 to perform a rope speed detection and judgment on the rope speed (S) again. Among them, the third preset rope speed is less than the second preset rope speed (Se < S2). When the real-time rope speed (S) is less than or equal to the third preset rope speed (S ≤ Se), as described in step S406: end the muscle training.

[0076] In addition, in this example, the method of performing exhaustive training also includes step S407: providing the historical data D4 (including the second preset resistance value (F2), the second preset rope speed (S2), the third preset rope speed (Se), and the degraded training resistance (F-)) to the built-in Bluetooth device 140 of the muscle strength training device 10, and making a telecommunications connection with the portable electronic product (smartphone) 12 of the operator 11, so as to store and / or set and / or modify the historical data D4.

[0077] In some embodiments, after performing exhaustive training, it also includes providing the operator 11 with a subsequent exercise plan, training menu, nutritional recipe, diet advice, or a combination of the above (as described in step S407) according to the training historical data through an application program, and timely encouraging or reminding the operator 11 to further strengthen training and supplement nutrition, so as to achieve the purpose of fitness and muscle building.

[0078] According to the above embodiments, this specification provides a muscle training device and a training method thereof, which connects an actuator and a resistor by a pull rope, so that the mechanical force applied by the operator to the actuator counteracts the reverse training resistance provided by the resistor. The displacement rope speed of the pull rope during the training process is measured by a resistance controller. At the beginning of the training, the resistor outputs a pre-set initial resistance with a small value, and according to the rope speed, the training resistance is superimposed in stages in order to find the maximum strength of the operator's muscles in real time, and limit the training resistance subsequently output by the resistor to be substantially less than or equal to the maximum strength of the operator's muscles. In the later stage of training, by performing exhaustion training, the operator's output can be evaluated in real time according to the measured rope speed, and the resistor is notified to adjust the output training resistance accordingly, thereby reducing sports injuries caused by excessive exercise intensity during training, and achieving the purpose of strengthening muscle strength for designated parts.

[0079] Although the present invention has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention.
