EMS, the technology electrically stimulated muscle workouts.

Normally, your muscles are made to move by signals transmitted by your brain. However, EMS (Electrical Muscle Stimulation) uses electrical stimulation to create an involuntary muscle contraction. Using the SIXPAD EMS training gear allows you to train your muscles anytime and anywhere, even while doing household chores or simply reading a book. What’s more, you don’t even have to break sweat.

EMS training
for easy body toning.

Muscles are made of extremely fine fibers which can be classified as slow-twitch and fast twitch muscle fibers. As fast-twitch muscle is easy to build, it haracteristically leads to a toned body if you train. On the other hand, with ordinary training it cannot be stimulated without imposing a load heavy enough to put you out of breath, and thereofore it requires hard training. EMS allows an approach which targets fast-twitch muscle even under a slight load, and therefore it can easily produce a change in appearance.

EMS for efficient training
- born from sports medicine research -

EMS devices that exist around the world have been configured at a variety of frequencies. What stimulus is needed in order to train muscles? Moritani views the problem from a sports science perspective and focuses on the mechanisms that build muscle by comparing and verifying the effects at different frequencies. As a result, he found that 20 Hz is the frequency at which muscles can be trained much more effectively than the other frequencies.

Test|Muscle tension
(= the power exercised by a muscle)

Tests have shown that when frequencies higher than 20 Hz are used, muscle tension falls off after about 60 seconds. The muscle's neurophysiological requirements cannot be met, and the effect of training leaves rather a lot to be desired. The conclusion is that when 20 Hz is used, muscle tension is maintained over time, which allows for sustained efficient training.

Test|Oxygen Consumption of Muscles

When exercised, muscles use energy and consume oxygen. It has been demonstrated that more oxygen is consumed and training efficacy is higher at 20 Hz than at other frequencies.

What stimulus is needed to train muscles?

Nowadays there are many people who have a big, bulging stomach, even though the food intake of people in their 20’s is lower than the post-war years. This is caused by the lack of muscle, not because of overeating. Professor Moritani states that muscles are the organs that burn the largest amounts of fat and sugar, and furthermore that when fat cells become bloated, it causes a number of diseases. Having muscle is one means of preventing illness.
