What is muscle electrical stimulation?
"Relax, pay attention to breathing, right, relax, pay attention to breathing..."
Put on Batman-like bodysuits, connect the electrodes, 1, 2, 3, a simple "rolling belly" action, "trapped in EMS (Electro Muscle Stimulation) equipment reporter I haven't been able to do it until I get to the 5th. I just feel that my body doesn't know which group of actions to start from. After 20 minutes, it is already sweating.
In the next few days, EMS fitness "sequel" came - full of muscle soreness, the feeling is almost exactly the same as "long time no exercise, suddenly come to the field", until four or five days later completely disappeared.
“The whole body EMS fitness mode is a comprehensive and targeted training of 90% of the muscles in a comprehensive and targeted manner. The muscles and activities can be increased from 30% to 50% of traditional strength training to 90%. So only 20 Minutes of EMS fitness, plus 10 minutes of stretching and relaxation, can meet the training needs of the week.†7+ New Concept Fitness founder Zeng Jing told the Journal of Chinese Journal of Science and Technology.
"EMS" literally should be "muscle electrical stimulation". According to reports, EMS fitness can simulate brain electrical signals, using low-frequency electrical impulses to stimulate muscle contraction, thus making up the "inert defects" of the brain and nerves.
Zeng Jing said that EMS technology has been in existence for hundreds of years, and the EU and the United States have approved applications in fitness and physical therapy rehabilitation. But this kind of systemic EMS fitness has only recently become popular. “It is not only suitable for professional athletes, but also for the general public. Especially for those who are not suitable for traditional fitness methods, such as some people with back joint problems.â€
The domestic hot discussion about "EMS" is mainly due to the listing of SIXPAD, a Japanese abdominal fitness equipment under the MTG company, which has attracted a group of young sports people. Since then, there have been domestic brands to launch this technology, and sold on the network platform.
For these products, the soreness is generally mentioned in the user experience, but there are doubts about whether it can really improve the strength.
Mainly used for relaxation and rehabilitation
There are many factors that affect the size of muscle strength, mainly myogenic and neurogenic factors. Myogenic factors mainly focus on muscle cross-sectional area, muscle fiber type, initial length and joint angle; while neurogenic factors are mainly concentrated in central activation, central nervous system coordination control of muscle activity and central nervous system excitability. In other words, the generation of muscle strength depends to a large extent on the intensity, frequency and level of nerve impulses emanating from the central nervous system.
For this reason, athletes who have been training for many years want to improve their muscle strength, mainly by increasing the intensity, changing the stimulation mode, and further increasing the frequency of nerve activation. Among them, functional electrical stimulation is an auxiliary means to induce muscle contraction with a certain frequency and intensity of current to improve muscle strength.
