Description

The present invention relates to training methods.

As exercise equipment used for human physical exercise, for example, there is a muscle electrical stimulator (see, for example, Patent Document 1). BACKGROUND ART A muscle electrical stimulator is expected to exercise a muscle and strengthen the muscle by applying a weak electric current to the muscle to tense and relax the muscle.

JP 2017-6644 A

Here, in order to increase muscle strength more effectively while using the electrical muscle stimulation device, after causing involuntary movement by the electrical muscle stimulation device, voluntary movement is performed in the direction opposite to the involuntary movement. There is training that gives a high load at. In the case of such training, a method of appropriately controlling the load so as not to become an excessive load while applying a high load more effectively has been sought.

The present invention has been made in view of such circumstances, and its object is to provide an effective training method using a muscle electrical stimulation device.

In order to solve the above problems, a training method according to one aspect of the present invention includes a process of starting application of electrical stimulation to a user's muscles by a predetermined muscle electrical stimulation device; During the process of moving the user's body in a first direction to swing the fluid while holding the predetermined exercise equipment containing the fluid inside, and the exercise equipment during the electrical stimulation being applied to the muscles of the user moving the user in a second direction different from the first direction while holding the .

Here, the "user" is the subject who implements the training method of the present invention, and uses the "exercise equipment" with one or more "muscle electrical stimulators" attached to one or more parts of the body. It may be a graspable subject. The “predetermined sports equipment containing a fluid inside” may be, for example, a cylindrical bag filled with water and air, and may have handles attached at multiple locations for the user to grip by hand. ``The user moves the body in the first direction to swing the fluid'' means that the user moves the body or the arm in the first direction to swing the fluid in the exercise equipment, and the movement is difficult to predict. It means to change the load by

According to this aspect, not only can a high load be applied to the muscles by voluntary movement in a direction that is opposite to the involuntary movement caused by the muscle electrical stimulation device, but also the unpredictable movement of the fluid in the exercise equipment You can vary the load on your muscles. This allows for more effective and efficient training.

Another aspect of the invention is also a training method. This method includes the steps of starting the application of electrical stimulation to a user's muscles by a predetermined muscle electrical stimulation device, and holding a predetermined exercise tool containing a fluid inside while the electrical stimulation is being applied to the user's muscles. A process in which a user in a resting state performs a plurality of types of exercise, and a process in which a user in a state of holding exercise equipment performs a plurality of types of exercise while electrical stimulation is applied to the muscles of the user.

According to this aspect, not only can a high load be applied to the muscles by voluntary movement in a direction that is opposite to the involuntary movement caused by the muscle electrical stimulation device, but also the unpredictable movement of the fluid in the exercise equipment You can vary the load on your muscles. Also, in order to avoid excessively increasing the load on the muscles for a long period of time, it is recommended to first start exercising without using exercise equipment, and then do the same exercise with exercise equipment. , the load on the body can be optimized. This allows for more effective and efficient training.

Yet another aspect of the invention is also a training method. The method involves grasping a predetermined exercise equipment during a period of time during which electrical stimulation of a predetermined frequency capable of producing tetanus in the muscles is applied to the user's muscles by a predetermined muscle electrical stimulation device that applies electrical stimulation to the muscles. The process of moving the user's body with the exercise equipment in a state of being in a state of being in a state of exercise, and applying electrical stimulation at a frequency lower than a predetermined frequency that can cause muscle twitches by the muscle electrical stimulation device for a period of time shorter than a predetermined time. Alternatively, a process of the user holding the exercise equipment moving the body together with the exercise equipment during the period in which the application of the electrical stimulation is stopped.

Here, the "predetermined frequency that can cause tetanus" may be, for example, a frequency in the range of 15 Hz or more and 30 Hz or less that can cause incomplete tetanus. Alternatively, it may be designed to use frequencies above 30 Hz that can cause complete tetanus, in which case the application time may be shortened. A "frequency capable of causing twitching" may be, for example, a frequency in the range of greater than 0 Hz and less than 15 Hz.

According to this aspect, not only can a high load be applied to the muscles by voluntary movement in a direction that is opposite to the involuntary movement caused by the muscle electrical stimulation device, but also the unpredictable movement of the fluid in the exercise equipment You can vary the load on your muscles. In addition, by repeating incomplete tetanus and twitching or resting, the ratio of muscle contraction and relaxation can be controlled, and more effective and efficient training can be achieved without applying excessive load. .

Any combination of the above-described constituent elements, or mutual replacement of the constituent elements and expressions of the present invention in methods, devices, programs, recording media recording programs, systems, etc. are also aspects of the present invention. is valid as

In addition, since the exercise equipment 60 can select the handle portion 70 to be gripped, more diverse exercises can be performed. In addition, since it is necessary to balance against swinging of the load-applying object G of the main body 62 due to exercise (change in the center of gravity of the main body 62), effective training can be performed.

<Training method> The training method of the present embodiment is hybrid training in which involuntary movement is caused by electrical stimulation of the muscle electrical stimulation device as described above, and then voluntary movement using exercise equipment as described above is superimposed. . The basic effects of each movement in this training are as follows. First, when moving a part other than the part where tetanus occurs due to the application of electrical stimulation, the entire form tends to be stable because the part where tetanus occurs is fixed in a contracted state. When moving the site where tetanus occurs, voluntary movement is performed to resist involuntary movement, and a high load can be obtained. When exercising while twitching occurs due to electrical stimulation, the body is exercised in an unbalanced state, so the trunk is strengthened. In this embodiment, there are a total of 16 types of exercise patterns, including patterns A+ to H+ that use the exercise equipment 60 and patterns A to H that perform the same movements without using the exercise equipment 60. is exemplified. Two types of exercise programs in which these 16 types of exercise patterns are combined with electrical stimulation patterns by the muscle electrical stimulation device and repeated will be described later.

Two types of exercise programs configured by combining the above 16 types of exercise patterns with electrical stimulation patterns will be described below. The first program assumes that the user wears the electric muscle stimulator on his/her legs, and is a simple exercise centering on the movements of the legs. Minimize leg movements to prevent falls. The second program is an exercise that can be expected to consume calories by dynamically moving the whole body, assuming that the user is wearing a muscle electrical stimulator mainly for the abdominal muscles. Both programs are assumed to take 23 minutes in total, but since using the exercise equipment 60 during the entire process may overload the user, menus using the exercise equipment 60 and menus not using the exercise equipment 60 are alternated. The program is configured to repeat

In addition, if electrical stimulation of a predetermined frequency that causes tetanus, such as 20 Hz that causes incomplete tetanus, is continuously applied throughout the program, muscle contraction may become excessive. and an application period of a frequency that causes twitching, for example, 4 Hz, are alternately repeated. Alternatively, it may be configured to alternately repeat a period in which electrical stimulation of a frequency causing tetanus is applied and a period in which it is not applied.

When the user holding the sports equipment 60 with both hands or holding the sports equipment 60 with both arms moves the body in the first direction while the electrical stimulation is applied, the fluid contained inside the sports equipment 60, for example, the liquid such as water oscillates in the first direction due to inertia, and erratic motion occurs due to splashing of the water. Subsequent movement of the body in a second direction different from the first direction causes the fluid in the exercise equipment 60 to further oscillate and cause erratic movement. In response to such unpredictable changes in the center of gravity, the user unconsciously reflexes to restore his or her posture. Therefore, you can train more effectively and efficiently.

FIG. 15 shows an exercise menu in the first program. In the illustrated table, each menu is listed in chronological order from top to bottom.

First, in "Warm up", which is a period for preparing for the start of training and warm-up exercises, the frequency from 2 Hz to 15 Hz that causes twitching is increased along with the output voltage over one minute. The first item is "no movement" for 60 seconds, but the muscles are moved and warmed by repeated twitches caused by electrical stimulation.

In the first training period "Training 1", a first period in which electrical stimulation is applied for 3 seconds at 20 Hz, which is a frequency that can cause incomplete tetanus, and a second period in which electrical stimulation is stopped for 2 seconds. and alternately for 5 minutes, while performing items 2-6 below.

As the second item, the "carry twist" of "pattern A" for 60 seconds is performed, and then the "hip circle" of "pattern B" is performed for 60 seconds as the third item. Next, after intervening 60 seconds of "no movement (rest)" as the fourth item, "carry twist" of 60 seconds of "pattern A+" is performed as the fifth item. "Pattern A+" of the fifth item is a "carry twist" that performs the same movement as "pattern A" of the second item, but "pattern A" performs a "carry twist" without using exercise equipment 60. On the other hand, "Pattern A+" is different in that a "carry twist" is performed while the sports equipment 60 is held or embraced. After the fifth item, perform a 60 second "Pattern B+" "hip circle" as the sixth item. "Pattern B+" of the sixth item is a "hip circle" that performs the same movements as the "pattern B" of the third item, but "pattern B" performs the "hip circle" without using exercise equipment 60. On the other hand, "Pattern B+" is different in that the exercise equipment 60 is held or embraced in a "hip circle".

For example, as a training effect in the state of using the electric stimulation device 10 of the type wrapped around the legs and lower back of FIG. Therefore, the overall form is stable. In addition, when the lower half of the body moves with the rebound of water at that time, a larger load can be obtained. In the hip circle of pattern B, since the lower body is actively moved, the electrical stimulation hinders the stretching of contracting muscles, and a greater load can be obtained. For example, as a training effect in the state of using the type of electrical stimulator 10a, b attached to the abdominal muscles, the carrying twist of pattern A not only increases the load of the horizontal rotation of the upper body, but also fixes the abdominal muscles in a contracted state. It stabilizes the upper body when moving the lower body. For example, as a training effect in the state of using the electric stimulation device 10c worn on the arm, since the muscles of the arm are fixed in a contracted state, the load on the arm increases when it moves due to the recoil of water. For example, as a training effect in the state of using the electric stimulator 10d of the type attached to the leg, the right and left balance can be adjusted by adjusting the left and right levels respectively. For example, all the above-mentioned effects can be obtained at once as a training effect when using the fitness wear type electrical stimulator 10g.

In the second training period "Training 2", the first period is to apply electrical stimulation at 20 Hz, which is the frequency that can cause incomplete tetanus, for 3 seconds, and the electrical stimulation is applied at 4 Hz, which is the frequency to cause twitching. During alternating periods of 5 minutes with a second period of application of the stimulus for 2 seconds, perform items 7-11 below. The first period of "Training 2" has the same frequency (20 Hz) and application time (3 seconds) as the first period of "Training 1". On the other hand, the application of electrical stimulation is stopped during the second period of "Training 2", whereas the electrical stimulation of 4 Hz is applied during the second period of "Training 1".

After performing "side bend" of "pattern C" for 60 seconds as the seventh item, "squat twist" of "pattern D" for 60 seconds is performed as the eighth item. Next, as the ninth item, "no movement (rest)" for 60 seconds is interposed, and as the tenth item, "side bend" of "pattern C+" for 60 seconds is performed. "Pattern C+" of the tenth item is a "side bend" that performs the same movement as the "pattern C" of the seventh item, but "pattern C" performs a "side bend" without using the sports equipment 60. On the other hand, "Pattern C+" is different in that a "side bend" is performed while the sports equipment 60 is held or held. After the 10th item, as the 11th item, a 60 second “Pattern D+” “Squat Twist” is performed. "Pattern D+" of the eleventh item is a "squat twist" that performs the same movements as the "pattern D" of the eighth item, but "pattern D" performs a "squat twist" without using the exercise equipment 60. On the other hand, "Pattern D+" is different in that the "squat twist" is performed while the exercise equipment 60 is held or held.

The effect of producing incomplete tetanus with 20 Hz electrical stimulation is the same as in the first training period, “Training 1,” but in “Training 2,” the muscle contraction is more active by further producing twitches. You can sway your body very quickly, so trying to balance stimulates your core. For example, in the case of a twisting motion, it is preferable that the body is fully moved in 3 seconds during incomplete tetanic contraction and is in the fully-moved position during twitch. When the twitch ends, it begins to move in the opposite direction. This maximizes the stroke of voluntary movement under the resistance of incomplete tetanus.

In the next 'Conditioning' period, the 12th item is 'no movement (rest)' for 30 seconds, and the frequency is sequentially increased from 2 Hz to 15 Hz to repeatedly generate twitches to relax the muscles.

The second period of "Training 3" has the same frequency (4 Hz) and application time (2 seconds) as the second period of "Training 3". On the other hand, electrical stimulation (20 Hz) is applied for 3 seconds in the first period of "Training 2", whereas electrical stimulation (20 Hz) is applied for 4 seconds in the first period of "Training 3".

As the thirteenth item, "Pattern A" of "Carry Twist" for 60 seconds is performed, and then, as the fourteenth item, "Pattern B" of "Hip Circle" is performed for 60 seconds. Next, after inserting "no movement (rest)" for 60 seconds as the 15th item, perform "carry twist" of "pattern A+" for 60 seconds as the 16th item, and "pattern for 60 seconds" as the 17th item.

The following items 19-23 are performed while alternating with a second period of 2 seconds of stimulation for 5 minutes. The second period of "Training 4" has the same frequency (4 Hz) and application time (2 seconds) as the second period of "Training 3". On the other hand, electrical stimulation (20 Hz) is applied for 4 seconds in the first period of "Training 3", whereas electrical stimulation (20 Hz) is applied for 5 seconds in the first period of "Training 4".
