It's time to turn to reliable elderly health care content in the family group

Researchers in cognitive physiology have found that molecules produced by muscles during exercise affect brain structure and healthy exercise can reduce the risk of Alzheimer's disease in older adults.

In fact, any exercise can effectively help your brain.

We tend to think that the brain controls the body and that the body sends sensory signals back to the brain; in other words, the brain is the supreme "commander" in the human body. Research in recent years has gradually revealed that the "commander" does not issue orders alone, but interacts with other systems in the human body, and the muscles in motion are one of the important factors that can have a wonderful effect on the brain.

Researchers have found that molecules produced during exercise are neuroprotective and beneficial to the nervous system.

University of California, San Francisco neuroscientist Victor The effects of exercise on the brain are multi-faceted, and exercise appears to enhance the brain's ability to regenerate neurons and enhance communication between neurons, said Saul Villeda, a senior researcher at the University of Toronto.

In addition, exercise can also significantly relieve anxiety and depression, so it is often used in psychotherapy. Evidence is mounting that exercise is good for the brain, but how exactly does this "magic" work? How Muscles Affect Your Brain Morning exercise crowd in Macau, China. Studies have shown that people who do aerobic exercise regularly have a larger hippocampus (an area important for learning and memory) in their brains than their sedentary peers. PHOTOGRAPH BY JONATHAN MEHRING, NAT GEO IMAGE COLLECTION Brain scientist Henriette van Praag has been investigating how exercise produces molecules that directly benefit the aging brain for more than 25 years. By subjecting dozens of mice to countless hours on the running wheel, Prager obtained data showing that exercise induces the creation of new neurons in the mice's brains, changes that accompany spatial memory and learning ability enhancement.

When muscle cells produce irisin, it can boost the brain Levels of another protein, BDNF, in the hippocampus. The hippocampus is one of the first brain regions to degenerate in neurodegenerative diseases, and BDNF promotes the continued growth of neurons and maintains the health of the hippocampus. Therefore, researchers believe that irisin may play a role in preventing neurodegeneration. Experiments showed that Alzheimer's mice that lacked irisin developed symptoms more quickly, and when they resumed irisin production, cognitive performance improved. So does this result apply to humans? Irisin has the same molecular structure in both mice and humans, so it may have similar functions in both species, but it remains to be seen whether it will work in human patients. Exercise also helps with emotional health. Strength training is critical in your daily activities—if you stick to strength training, getting up from a chair, climbing stairs, and carrying things will be a lot easier. PHOTO: HANNAH REYES MORALES, NAT GEO IMAGE COLLECTION It's not just muscles that "talk" to the brain. When you exercise, protein molecules produced by your liver, fat, and bones all interact with your brain to sharpen your mind and avoid anxiety and depression. Other scientific teams are studying the effects of irisin on depression, and if a drug that is effective and has no unintended consequences can eventually be designed, it could mean that humans can age in a healthier way and enjoy longer periods of high health. quality of life. It doesn't matter when or where you exercise, the important thing is to get moving!

MORTON, NAT GEO IMAGE COLLECTION The ultimate goal of the research team is to develop a drug that mimics the effects of exercise on the brain, so that people with limited mobility or frailty can enjoy the benefits of exercise. This may be the dream of lazy stars: one day, we will be able to maintain our health without running and exercising in a sweat. However, the molecules produced by exercise affect multiple systems in the human body in many ways, and unraveling the various dependencies between them is a complex problem, and it will take time to develop usable clinical drugs. For a healthy and active brain and a sunny mood, put down your phone now and get up and move! Exercising with your dog is a trend these days! PHOTO: LYNN JOHNSON, NAT GEO IMAGE COLLECTION
