Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garment in which an electrode for measuring an action potential generated by muscles is attached.
[0002]
[Problems to be solved by the invention]
Muscles and nerves generate action potentials when excited. An electromyogram is a record of changes in muscle and nerve potentials.
When fatigue occurs due to muscle movement, the action potential of the electromyogram increases with myalgia.
Further, when the muscle is in a fatigued state, if the muscle is stretched, the muscle fatigue is recovered and the action potential of the electromyogram is reduced.
Thus, since the fatigue state of the muscle can be known from the increase or decrease of the action potential of the electromyogram and the appropriate timing to be cared for can be known, more rational strength training can be performed.
[0003]
On the other hand, when the muscle tension is increased by applying a load to the muscle, the action potential of the electromyogram also increases linearly in proportion thereto.
When the maximum muscle strength is increased by training, this action potential improves the electrical activity efficiency of the muscle group even if the same load is applied, and the action potential of the electromyogram decreases and the slope of the increasing straight line also decreases. .
Thus, since the maximum muscle strength is known from the value of the action potential with respect to the load, it is possible to quantitatively grasp the effect of the strength training using the maximum muscle strength as an index.
[0004]
In order to measure action potentials of various muscles constituting the human body, a number of electrodes must be attached to each part of the human body.
In addition, these electrodes need to be attached accurately at the correct position for measuring the muscle action potential.
For this reason, it is difficult to attach the conventional electrode correctly because it is cumbersome and troublesome to attach, and the correct position is not known accurately.
[0005]
Therefore, the present invention is intended to make it possible to easily measure action potentials of various muscles constituting a human body simply by wearing clothes by attaching electrodes to predetermined locations inside the clothes. is there.
