After the epidemic, the government advocated the national strategy of "national fitness". It can be said that in the era of comprehensive fitness, whether it is running, lifting iron, or square dance fitness exercises, they have provided a good way for people's health. However, it should be noted that with the growth of age, the human body has gradually become unable to withstand high-intensity exercise, and even Sports injury has occurred. The key reason for this is muscle loss, which leads to the loss of vitality of muscle stem cells and the degradation of exercise ability
How can I restore my physical condition to a youthful state? A scientific team has conducted a series of studies on this issue. Researchers from the École Polytechnique Fédérale de Lausanne in Lausanne, Switzerland and other institutions found that NMN supplementation can significantly increase the number of muscle stem cells in elderly mice During the research process, scientists compared young and elderly mice and found that muscle stem cells in elderly mice were significantly reduced, only about half of that in young mice. NMN supplementation can significantly increase the number of muscle stem cells in elderly mice, achieving a similar effect to exercise, or can be used to strengthen exercise and help muscles return to their youthful stateOn January 19, 2021, Professor Johan Auwerx, the absolute authority of mitochondrial research, also wrote that NAD+supplementation can improve mitochondrial function in a variety of animal models, reduce amyloidosis, and then significantly delay muscle aging and extend the healthy period. The study was published in the sub journal Cell, a top scientific journal
Professor Johan Auwerx's research not only identified the causes of muscle aging, but also emphasized the role of NAD+in slowing or even reversing aging through cellular mechanisms. Muscle aging is one of the root causes of the sudden decline in the quality of life and health level of middle-aged and elderly populations, and NMN is a precursor of NAD+that can be converted into NAD+in the body, slowing down muscle aging and delaying agingIn addition, a study from the Sports in Japan Science University also found that the level of NAD+in the human body will not only decrease with aging, but also with intense exercise. The experimenter employed 10 young healthy men to take NMN orally and placebo for double-blind control. After taking NMN for one week and cycling for 45 minutes at the exercise intensity of 60% of the VO2 max, the subjects increased the exercise intensity to the maximum and measured the time until exhaustion
The result data shows that there is no change in the body composition after taking NMN, but the respiratory exchange rate is significantly reduced, sugar consumption is inhibited, and lipid metabolism is higher. This indicates that the body is more energy-efficient after taking NMN, can maintain NAD+levels, and can exercise more comfortably at the same intensity Without a doubt, exercise is a "good medicine" for maintaining a youthful state, and supplementing NMN while exercising can improve exercise ability, improve muscle levels, and optimize exercise effects. For the elderly, NMN supplementation can also activate muscle stem cells, delay aging of muscles and reduce the occurrence of Sports injury
