"The whole-body EMS fitness mode is a comprehensive and targeted synchronous training for 90% muscle groups with the help of special equipment, and the muscle activity can be improved from 30% to 50% of traditional strength training to 90%. So as long as 20 minutes of EMS fitness, plus 10 minutes of stretching and relaxation, you can meet the training for one week. " Ceng Jing, founder of "7+ New Concept Fitness", told China Science News. "EMS" literally means "muscle electrical stimulation". According to reports, EMS fitness can simulate the electrical signals in the brain and stimulate muscle contraction with low-frequency electrical pulses, thus making up for the "inertia defects" of the brain and nerves.

It has been said that EMS technology has a history of 100 years and has been approved for fitness and physical rehabilitation in the European Union and the United States. But comprehensive EMS exercise has only recently become popular. "It applies not only to professional athletes, but also to the general public. Especially those who are not suitable for traditional fitness methods, such as those with problems in the back joints. " China's heated discussion about "EMS" is mainly due to the launch of SIXPAD, an abdominal health equipment owned by Japanese MTG company, which attracted a group of young sports experts. Since then, domestic brands have launched this technology and sold it on the network platform.

For these products, pain is generally mentioned in the user experience, but there is doubt whether it can really improve the strength. Muscle is an important part of our body. Take the elbow as an example. We regard an action as a war, which only leads to completion in skeletal muscle (generally), but generally we can't make it free from our brain (king), only the motor nerve (messenger) that dominates skeletal muscle transmits the impulse (roller) to skeletal muscle (generally), making it excited to contract and elbow flexion and extension. However, when neuromuscular excites, the biological potential changes. Electrodes are used to guide the bioelectric potential generated in muscles, and a certain waveform can be displayed by amplification, which is electromyography.
