DENBA has been installed at "DAH" a high-end fitness club in Japan, to help members recover from muscle fatigue in their training. Some DENBA are put in several rooms, thus, members are able to use even during their training. DENBA doesn't require contact with the mat, thus, some members can get benefits from DENBA as the same time.

The data that can be presented objectively are the values of thigh circumference and knee extension muscle strength.

It is believed that there is a significant relationship between thigh circumference and muscle strength, and this measurement is often used by medical institutions as a postoperative functional test.

While it is not uncommon for postoperative patients to have residual left-right differences in thigh circumference even 2 years after surgery, we believe that both athletes have achieved very good recovery at 6 months postoperatively, with no significant left-right differences.

As for recovery of muscle strength, Fujimaki's recovery of knee extensor strength was a little delayed due to "difficulty extending the knee," which may have been caused by a postoperative complication, but he has recovered well at this point. As for Oka, his recovery has been so phenomenal that it could be described as "abnormal.

I strongly feel that both athletes have made good progress in their recovery, as they have been able to work through the period of increased practice in gymnastics itself in conjunction with qualitative and quantitative increases in the content of rehabilitation and training from around six months after surgery, without leaving fatigue behind on the following day.

A study on the improvement of sleep disorders using DENBA Health has now demonstrated a significant reduction in sleep disorders. The joint research was conducted at China's only state-level geriatric research institute. The empirical study was conducted at the Beijing Institute of Geriatrics of the National Health Commission.

The study subjects were 81 people, including those who reported having sleep disorders, of whom 40 were men and 41 were women, with an average age of 63 years. The main causes of sleep disorders are poor sleep quality, early sleep duration, low sleep depth, frequent dozing throughout the day and frequent awakenings, which are risk factors associated with conditions such as mental dementia, chronic illness, anxiety and accidental injury. Using a randomised controlled study, the present study showed that the sleep quality of the examinees before and after the AC electric field technology intervention was significantly improved. This was evidenced by a reduction in the frequency with which recipients were unable to sleep, woke up during the night and felt sleepy during the day.

As the market for sleep therapy continues to grow, and is estimated to be worth 3 trillion yen in Japan alone, DENBA will further accelerate its research into improving health by improving sleep disorders, and expand from Japan to Asia and the rest of the world.

DENBA JAPAN is pleased to announce that it has demonstrated and proved the effectiveness of DENBA health in increasing the activity of the antioxidant enzymes (SOD) superoxide dismutase and glutathione peroxidase and the ability to remove hydroxyl radicals and superoxide anion radicals in the body. The results of this study are as follows.

Extract from Wikipedia

Superoxide dismutase (SOD) is an enzyme that decomposes reactive oxygen species generated in cells. It is said that there is a correlation between the strength of SOD activity in relation to the amount of oxygen consumed and life expectancy, which suggests that the life expectancy of animal species that consume more oxygen relative to their body weight should be shorter, but that SOD prolongs life expectancy by decomposing reactive oxygen species. The high activity of SOD in primates, especially humans, stands out and is considered to be one of the reasons for the long life span of humans.

2O2- + 2H+ + SOD → H2O2 + O2

Three types of SOD are known, Cu/Zn, Mn and Fe, depending on the metal they contain; SOD is widely present in plants and mammals. They are present in high concentrations in the brain, liver, heart, erythrocytes and kidneys, and in humans there are three types: cytosolic Cu/Zn-SOD, mitochondrial MnSOD and extracellular SOD.

Intracellular and extracellular levels of SOD are important for the prevention of oxidative stress-related diseases; mutations in SOD are found in approximately 20% of cases of familial amyotrophic lateral sclerosis (ALS). SOD is also considered important in the prevention of other neurodegenerative diseases such as Alzheimer's, Parkinson's and Huntington's diseases, where SOD catalysis is very fast, with a turnover rate of 2 x 109 M-1sec-1 , and when sufficient amounts of SOD are present in the cells and tissues, superoxide is usually superoxide is kept at very low levels. Quantification of SOD activity is essential for identifying the antioxidant capacity of biological systems.

Glutathione peroxidase is the generic name for a family of enzymes with peroxidase activity whose main biological role is the protection of organisms from oxidative damage. The biochemical functions of glutathione peroxidase are the reduction of lipid hydroperoxides to the corresponding alcohols and the reduction of free hydrogen peroxide to water.

In a study by the University of Tsukuba on the transient effects of the DENBA environment on the physical fitness and cognitive functions of the elderly, it was found that a two-hour stay in the DENBA environment temporarily improved the lower limb muscle strength of the elderly, and that it may also improve executive function and hand dexterity, which are indicators of cognitive function. The study also showed that "executive function and hand dexterity, indicators of cognitive function, may also be improved".

The fact that the effectiveness of DENBA in improving lower limb muscle strength and cognitive function has been demonstrated so far after only two hours of short-time use is a strong indication of the potential health benefits of DENBA.
