Description
本発明は、筋力増強を効率よく行える電気的筋肉刺激装置に関する。 The present invention relates to an electrical muscle stimulation device that can efficiently increase muscle strength.
電気信号による刺激で筋肉を伸縮させ、受動的に運動を行わせるトレーニング装置が従来より知られている。
開示した特許文献１の発明によれば、低周波のパルス列信号で刺激するとともに、超音波も同時に照射して効果を高める発明が開示されている。
2. Description of the Related Art Conventionally, a training device that stretches and contracts muscles by stimulation with an electrical signal and passively exercises is known.
According to the disclosed invention of Patent Document 1, there is disclosed an invention that enhances the effect by stimulating with a low-frequency pulse train signal and simultaneously irradiating ultrasonic waves.
また、能動的運動においては負荷運動と称する効率の良いトレーニング方法が知られている。
負荷運動は、筋肉に軽い負荷を掛けた状態で更に強い負荷をかけるトレーニング方法である。
例えば、中腰の状態から屈で、また中腰状態まで伸ばす屈伸運動などが相当する。
この屈伸運動では、中腰状態が筋肉に軽い負荷をかけた状態であり、伸び運動が強い負荷を筋肉にかける状態となる。
The load exercise is a training method in which a stronger load is applied while a light load is applied to the muscle.
For example, it corresponds to a flexion / extension motion that bends from the middle waist state and extends to the middle waist state.
In this bending and stretching exercise, the middle waist state is a state where a light load is applied to the muscle, and the stretching exercise is a state where a strong load is applied to the muscle.
従来の電気的筋肉刺激装置は、刺激電気信号のＯＮ／ＯＦＦで筋肉を伸縮させるものであり、負荷運動に相当するトレーニングができない。 すなわち、筋肉に軽い負荷をかける状態を再現できない。
そこで本願発明は、電気信号の刺激で負荷トレーニング同様のトレーニングが可能となる電気的筋肉刺激装置の提供を課題とする。
The conventional electrical muscle stimulating device expands and contracts the muscle by turning on / off the stimulation electrical signal, and cannot perform training corresponding to the load exercise. That is, it is not possible to reproduce a state where a light load is applied to the muscle.
Therefore, an object of the present invention is to provide an electrical muscle stimulation device that can perform training similar to load training by stimulation of an electrical signal.
定期的に間欠するパルス列の主信号と主信号とは異なるタイミングで間欠するパルス列の副信号を刺激信号として用いる。
主信号と副信号との出力強度設定を行う操作手段と、
操作手段になされた設定に応じて主信号及び副信号を出力する刺激信号発生手段とで構成する。
副信号の出力強度設定が主信号の出力強度設定を超える操作がなされた時に刺激信号発生手段は、
副信号の強度を主信号の強度以下に抑制して出力するようにする動作ささせる。
上述の方法で生成した刺激信号を鍛えたい部位に印加することで課題を解決する。
The main signal of the pulse train intermittently intermittently and the sub-signal of the pulse train intermittent at different timings are used as the stimulation signal.
Operation means for setting the output intensity of the main signal and the sub signal;
It comprises stimulus signal generating means for outputting a main signal and a sub signal according to the setting made in the operation means.
When the output intensity setting of the sub signal exceeds the output intensity setting of the main signal, the stimulus signal generating means is
The operation is performed so that the intensity of the sub-signal is controlled to be equal to or less than the intensity of the main signal.
The problem is solved by applying the stimulation signal generated by the above-described method to a site to be trained.
また、他の手段は以下である。
定期的に間欠するパルス列の主信号と主信号とは異なるタイミングで間欠するパルス列の副信号を刺激信号として用いる。
主電信号の強度設定と主信号に副信号を重畳させるか否かの設定とを行う操作手段と、
操作手段になされた設定に応じて主信号及び副信号を出力する刺激信号発生手段とで構成する。
主信号に副信号を重畳させる設定がなされた場合に刺激信号発生手段は、主信号強度の予め定めた割合（５０％〜７０％）の強度で副信号を出力するように動作させる。
上述の方法で生成した刺激信号を鍛えたい部位に印加することで課題を解決する。
Other means are as follows.
The main signal of the pulse train intermittently intermittently and the sub-signal of the pulse train intermittent at different timings are used as the stimulation signal.
Operation means for setting the strength of the main electric signal and setting whether to superimpose the sub signal on the main signal;
It comprises stimulus signal generating means for outputting a main signal and a sub signal according to the setting made in the operation means.
When the setting for superimposing the sub-signal on the main signal is made, the stimulus signal generating means is operated so as to output the sub-signal at a predetermined ratio (50% to 70%) of the main signal intensity.
The problem is solved by applying the stimulation signal generated by the above-described method to a site to be trained.
主信号より弱い強度の副信号で筋肉に負荷を掛けておき、主信号で強い負荷を筋肉に与えるので、能動的な負荷運動に相当するトレーニングが行うことができる。 すなわち、筋肉増強に対して高い効果が得られる。 Since a muscle is loaded with a weaker sub-signal than the main signal and a strong load is applied to the muscle with the main signal, training corresponding to active load exercise can be performed. That is, a high effect on muscle strengthening can be obtained.
