Why don't you want to exercise?

Although exercise is the best way to go for many diseases, we are not willing to exercise and sweat. We can almost write a detective novelist Su. There are so many books in Sue Grafton's complete works. Although our excuses may be ridiculous (I took a big box of donuts to climb the stairs when I was at work today) or it is reasonable (I had a dog bit my big toe while running yesterday), we were only a small part of the amount of movement we needed, which was almost unquestionable.

The reason is obvious. Sports can cause pain, make people uncomfortable, and smelly. Since you have time, why do you have to make yourself so tired, instead of holding chocolate matinee and watching an episode of Cupcake Wars? It is true that sports are not as good as homework, but the problem is that we have already appreciated ourselves to the point where it is too hard to even press the remote control, so we can also use the sound control to stream the next episode of "Diners, Drive-Ins and Dives".

In modern society, because we make all our work easy, even running lightly will make people feel that it will be hard to do it. Science has listed the benefits of exercise in detail: making strength stronger, energetic, lowering blood pressure, reducing stress, reducing depression, reducing weight, and reducing the chance of many and overweight related diseases. Research also points out that exercise can even prolong life, improve learning and memory abilities, and reduce mental aging. So why can't we always get up and go for exercise? The

gene may become part of the answer. Research on twins shows that the combination will affect our desire to go sports or rest. Some people's natural genes are not suitable for certain types of sports. Kathlin from Sydney University in Australia. Research led by Kathryn North points out that the performance of athletes is related to the gene ACTN3. ACTN3 protein is located in a muscle fiber that can quickly retract to produce high-speed movement. Sprinters and Kinderella players contain many of this protein. And some people contain a sudden change that stops making this protein, which is more suitable for endurance exercise. So you like sprinting or long running, heavy or aerobic exercise, and the reason may be that the genes that make muscles are different.

Professional athletes have undoubtedly received strict training, but some people have the talent brought by genes. Some of the benefits caused by the transmission are very obvious, such as basketball players tend to be too high to pay attention to aircraft flying too low. However, sometimes the advantages of passing are more obscure. Olympic Sports Superstar Airo. Eero Mantyranta is easy to ski cross country, and we know the reason why this high-strength competition is easier for him. His erythropoietinreceptor has undergone a sudden change, which makes the amount of red blood cells produced in his body much higher than that of ordinary people. Compared with the more players in the same field, he can deliver more oxygen to the extremely aerobic muscles. This example brings up an interesting question: If you compete with people like this, do you think it is fair? If you think this is fair, then you should allow taking red hematopoietin to increase your red hematopoietin reading, and choose Morans by yourself. Lance Armstrong admitted that he had used this hormone.

The reason why some people prefer sports is that after spending energy, their brains feel more rewards. Genetic changes that involve dopamine remuneration systems in the brain may be related to the amount of physical activities of some people. If you can get paid after running, you will be more inclined to move. If you don't feel the reward at the gym, you may have to find other ways to do sports.

Any Garfield cat fan knows that humans are not the only animals that will be vital. Franc from the University of Missouri. Frank Booth noticed that some rats in his laboratory were more diligent in moving in the rolls, while some were like horses. Homer Simpson avoids turning on the bike. His team selected rats who like sports differently, and then cultivated rats who like sports and rats who love sports, comparing the differences in brain gene expression between the two. Some differences support the different approach of dopamine reporting for the two systems, that is, some people feel the reporting after the movement, while others don't.

Eating junk food will significantly reduce the motivation of sports, which is another fatal blow to health by junk food. Research points out that Western diet and laziness are closely related to depression. The conclusion made by top researchers is that obese people are not necessarily because of laziness or lack of self-discipline, but because junk food changes their emotions and behaviors. The verification performed by rats has implemented this theory. Rats’ unhealthy foods will not only make them fat, but also reduce their motivation to carry out reporting tasks.

Scientists also examined the differences in microbial phase between athletes and non-sports, and many differential patterns also occur between healthy and unhealthy dieters.. In 2017, Ola, a computer biologist at the TeagascFood Research Centre, Irish Cork County. Orla O’Sullivan compared the tract microbial phases of British rugby male athletes and four-body non-movement males. Among male athletes, not only are the microbial phases more similar, but there are many health-promoting Ekmania. In addition, although athletes suffer from muscles, they suffer from less inflammation, and one of the reasons may be because their microbial phases are more conducive to health.

{twenty three} {twenty four} Regularly, the microbial types of people who work in sports produce butyric acid, which has strong anti-inflammatory effects. Malia from European University, Madrid, Spain. De. Horse. Larossa. Mariadel Mar Larrosa Perez also discovered in 2017 that women who work in heavy sports (Wednesday to Friday hours) have more microorganisms than those who do not. Even if you exercise lightly, the number of beneficial bacteria in Ekmania can increase.
