Proven Science

EMS is an efficient way to train, brought by sports science research.

Professor Emeritus of Kyoto University
Toshio Moritani, PhD

Toshio Moritani is a driver in the field of sports science and has been studying the training effect that EMS produces on muscles for over 40 years. Moritani has repeatedly verified that an efficient frequency for training is 20 Hz. His papers are garnering a great deal of attention from researchers around the world.

What stimulus is needed to train muscles?

Nowadays there are many people who have a big, bulging stomach as a result of the so-called metabolic syndrome, even though the food intake of people in their 20’s is lower than the post-war years. In other words, it is not overeating but the lack of muscle that causes metabolic syndrome.
Moritani’s thesis is that muscles are internal organs that burn large amounts of fat and sugars, and furthermore, when fat cells become bloated, it causes a number of diseases. Having muscle is one means of preventing illness.


Cross-section of Muscle Fiber

EMS training makes it easy to tone and firm the body.

Muscles are made of extremely fine fibres which can be classified as slow-twitch and fast-twitch muscle fibres. As fast-twitch muscle is easy to build, it characteristically 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, so another aspect is that it requires hard training. Because EMS allows an approach that targets fast-twitch muscle even under a slight load, it can easily produce a change in appearance.




Subject of Analysis: Muscle Tension (=strength exhibited by muscles)

When frequencies exceeding 20Hz are applied for approximately 60 seconds, muscle tension declines. As a result, the necessary neurophysiological conditions are not achieved and the expectations for any muscle training results become low.

At 20Hz, the muscle tension is maintained over a prolonged period of time. Therefore, it was concluded that the frequency is effective for continuously training muscles.

EMS is a key to the future of muscles

The topic of discussion today, electrical stimulation of skeletal muscles, can be viewed as an element in increasing the independent and healthy life expectancy of the elderly by being used to fight sarcopenia for example, which is the loss of skeletal muscles that can result in elderly people falling down and breaking bones. We are now researching and developing our product so that electrical stimulation devices will be used in various ways, with the dream and hope that people around the world can use electrical stimulation of skeletal muscles for their own health care, health preservation and health improvement, or to prevent deterioration of muscles and weight gain.
