BACKGROUND

Technical Field

The present invention relates to a resistance control method, resistance system and software designed for eccentric weight training through monitoring velocity change.

Related Art

At present, when carrying out training with weight training equipment, it can be divided into a centripetal stage and an eccentric stage. The centripetal stage is to provide weight-bearing during the muscle contraction stage, and conversely, the eccentric stage is to provide weight-bearing when the muscles are stretched. However, when operating the equipment, the output resistance set by the equipment is based on a fixed value or different values given by different movement angles. That is, no matter whether it is concentric or eccentric training, the output resistance has been set before the movement begins. This also causes the user to be slightly careless during the training process, such as letting go or being unable to bear it, the user will be injured by heavy pressure or pull from a fixed resistance value.

SUMMARY

The present invention provides a velocity based eccentric weight training (VBET), which mainly aims to overcome the dangerous problems of the conventional weight-based eccentric weight training. The inventor of this application proposed eccentric training based on velocity. By monitoring the velocity, the weight is dynamically adjusted to maintain a stable eccentric weight training velocity (muscles in the direction of stretching). The advantages of this method are as follows:

High safety: If the user suddenly let go, the conventional equipment will become faster due to the fixed weight, or even stall and pop out, causing dangerous injuries. However, the present invention will immediately reduce the force to maintain the predetermined velocity and avoid causing pressure or injury to the user.

A sense of achievement: The resistance weight is dynamically adjusted based on the real-time velocity of the equipment. If the user's resistance is strong, the equipment will slow down. On the contrary, if the user's resistance is weakened, the equipment will accelerate. Dynamic adjustment of resistance based on velocity ensures that the user can complete training according to their own physical condition, which can greatly enhance the sense of achievement in completing exercise and the improvement of muscle strength.

Reduce the risk of injury: The resistance weight is dynamically adjusted based on the real-time velocity of the equipment. If the user's resistance is strong, the equipment will slow down. On the contrary, if the user's resistance is weakened, the equipment will accelerate. Resistance is adjusted based on velocity. Dynamic adjustment of resistance based on velocity can keep the moving velocity constant without problems of sudden pulling or heavy pressure. Therefore, during the eccentric training process, the resistance value at which the user can safely complete the eccentric exercise will be dynamically generated to avoid injuries caused by insufficient muscle strength when the user's output force is less than the resistance.

To achieve the above object, a resistance control method for eccentric weight training of the present invention includes the following steps: a velocity acquisition step, a state identification step and a resistance control step. Wherein, the velocity acquisition step real-timely acquires the moving velocity of a user's moving parts through a velocity capturing device, and transmits the moving velocity back to a control system. The state identification step is based on the control system comparing obtained the moving velocity with a predetermined value. When the moving velocity is greater than the predetermined value, it is defined as a too fast state; when the moving velocity is less than the predetermined value, it is defined as a too slow state. The resistance control step is for the control system to adjust the resistance of the equipment of the adjustable resistance device according to the state obtained in the state identification step. When the control system determines that the state is too fast, the output force of the resistance device will be reduced; When the system determines that the state it is too slow, the output force of the resistance device will be increased. Through this method, the user can determine the amount of force applied to complete the exercise according to the user's physical condition when performing eccentric weight training, which has the effect of preventing exercise injuries and increasing exercise effects. In addition, the frequency of capturing the moving velocity of this method can be at least 1 time/second, and the frequency of capturing can be increased according to the requirements of precision, such as 50 times/second.

Furthermore, this embodiment provides that the velocity capturing device can be further connected to an image capturing device to analyze the captured image to obtain the velocity of the user's moving parts; or, the velocity capturing device can be further connected to the adjustable resistance device, and the moving velocity is calculated based on the displacement change value of the adjustable resistance device. In this way, the moving velocity can be obtained according to movements with different attributes to improve the accuracy of resistance device control.

Furthermore, in this embodiment, the predetermined velocity value can be set to a certain value, or can be converted according to the measurement result of the user's range of motion. This allows you to set target values that match your personal abilities to avoid exercise injuries.

Furthermore, this embodiment is further set to when the moving velocity is greater than the predetermined value, and the moving velocity is greater than the predetermined value plus a first tolerance value, the too fast state is determined; when the moving velocity is less than the predetermined value, and the moving velocity is less than the predetermined value minus a second tolerance value, the state is determined to be too slow; when the moving rate is between the too fast state and the too slow state, the system does not adjust the resistance device. By setting the first tolerance value and the second tolerance value, a flexible interval for judgment can be provided to allow the user has time to break through continuously.

Based on the above method, the present invention further provides a resistance system for eccentric weight training, which includes a resistive force device and a control device, and the control device is signal-connected to the resistive force device. The resistive force device is used to be installed on a weight training equipment to provide the load required by the weight training equipment during exercise. The control device is used to execute the aforementioned method, so that the weight training equipment performs eccentric weight training according to the aforementioned method.

The present invention further provides a resistance control software for eccentric weight training, which can be installed in a control system of a weight training equipment with resistance control, and enables the control system of the weight training equipment to execute the aforementioned method.

DETAILED DESCRIPTION

Please cooperate with what is shown in FIG. 1. The present invention is a resistance control method for eccentric weight training, which is suitable for equipment with an adjustable resistance device F. The method includes the following steps: a velocity acquisition step S1, a state identification step S2 and a resistance control step S3.

Wherein, the velocity acquisition step S1 obtains the moving velocity of a user's moving parts or the equipment in real time through a velocity acquisition device V, and transmits the moving velocity back to a control system C. Wherein, the moving parts may be arms, joints, palms, heels, soles, calves, thighs, etc., or parts in contact with the equipment. The velocity acquisition device V is to obtain the real-time velocity of the moving parts or equipment on the movement path of eccentric weight training. In particular, ordinary skilled in the art can undoubtedly understand that the “moving velocity of the equipment” refers to the position of the parts within the equipment that cooperate with the user's movement, rather than the movement of the “equipment” as a whole. In addition, the frequency of capturing the moving velocity can be more than once per second (1 time/second), and if it exceeds 50 times per second (50 times/second), the effect will be better. Furthermore, in this embodiment, the velocity acquisition device V can be further connected to an image capturing device V1 to analyze the captured image to obtain the displacement of the user's moving parts or equipment, and convert it into velocity. Or, the velocity acquisition device V is connected to the adjustable resistance device F, and the moving velocity can be obtained by performing reverse calculation based on the input current change value, voltage change value or displacement change value of the adjustable resistance device F. In this way, the moving velocity can be obtained according to the cooperation of movements with different attributes, so as to improve the accuracy of controlling the adjustable resistance device F.

In the state identification step S2, the control system C performs comparison and classification based on obtained the moving velocity and a predetermined value. When the moving velocity is greater than the predetermined value, it is defined as a too fast state. When the moving velocity is less than the predetermined value, it is defined as a too slow state. Through the classification of status, it is used to adjust the execution power in subsequent steps.

The resistance control step S3 is for the control system C to adjust the resistance of the adjustable resistance device F according to the state obtained in the state identification step S2. When the control system C determines that the state is too fast, the output force of the adjustable resistance device F will be reduced; when the control system C determines that the state is too slow, the output force of the adjustable resistance device F will be increased. Wherein, the output force adjustment value of the adjustable resistance device F can be reduced or increased with a minimum change amount according to the settings of various adjustable resistance devices F, or the adjustment value of the reduction or increase can be predetermined by the system.

Through the operation of this method, the user can effectively improve muscle strength and prevent exercise injuries when performing eccentric weight training. In addition, the frequency of capturing the moving velocity of this method can be at least 1 time/second, and the capture frequency can be increased according to the precision requirements, such as 50 times/second or even higher. This allows the user to not obviously feel the resistance adjustment process during operation. In addition to protecting the user's muscles, it can also increase the user's confidence.

Furthermore, the velocity predetermined value in this embodiment can be set to a certain value, or it can be automatically generated by conversion based on the user's range of motion measurement results. In this way, each operator can have a target value that is consistent with personal abilities and avoid exercise injuries caused by excessive exertion.

Furthermore, this embodiment further sets a first tolerance value in the control system C. When the moving velocity is greater than the predetermined value, and when the moving velocity is greater than the predetermined value plus a first tolerance value, the too fast state is determined. (The judgment formula is: moving velocity>(predetermined value+first tolerance value))

When the moving velocity is less than the predetermined value, and the moving velocity is less than the predetermined value minus a second tolerance value, it is determined that is too slow state. (The judgment formula is: moving velocity<(predetermined value−second tolerance value)) In addition, the first tolerance value and the second tolerance value may be the same value or different values.

When the moving velocity is between the too fast state and the too slow state, the system does not adjust the resistance device. The tolerance value is also a velocity value, which can be customized by the user, set by the coach, or set by the system manufacturer. By setting the tolerance value, a flexible range of judgment can be provided to provide the user with time and opportunity to continue their breakthrough.

An embodiment of the present invention further provides a resistance system suitable for eccentric weight training, which includes an adjustable resistance device F and a control device C. The control device C is signal-connected to the adjustable resistance device F. The adjustable resistance device F is used to be installed on a weight training equipment to provide the load required for exercise of the weight training equipment. The control device C is used to execute the aforementioned method, so that the weight training equipment performs eccentric weight training according to the aforementioned method. The adjustable resistance device F may be an electric damping device controlled by electricity.

The present invention further provides a resistance control software for eccentric weight training, which can be installed in a control system of a weight training equipment with resistance control, and enables the control system of the weight training equipment to execute the aforementioned method. Through the setting of the resistance control software of the embodiment of the present invention, it can be quickly installed on exercise equipment having a control device C and an adjustable resistance device F, so that exercise equipment can protect the user when performing eccentric weight training.

The present invention provides a kind of velocity based eccentric weight training (VBET), which overcomes the shortcomings of the conventional technology that does not assist the eccentric weight training, and dynamically adjusts the weight through the monitoring of velocity to maintain the velocity of eccentric weight training or the time to complete eccentric weight training is within a set range, especially to increase safety, enhance a sense of accomplishment, and reduce the risk of injury.
