It is worth seeing. It's really a good documentary. Its research results have subverted many people's ideas and common sense. I appreciate and admire foreign scientific research that "has pictures and truth". No matter what the topic is, the theory is based on accurate data and long-term observation and experiments, rather than taking it for granted. But in fact, the core research of the whole video is aimed at the health field. The so-called "truth of sports" is aimed at the influence of sports on the human body. It's not about fitness, so don't misunderstand some research results. Next, summarize the video: I saw this documentary a long time ago. At that time, there were no Chinese subtitles, so I had only a little knowledge. This time, I watched it again from beginning to end. Because the whole video is relatively long, close to 50 minutes, it is estimated that only a boring fitness enthusiast like me will really watch it. This is really a good documentary, which subverts many people's ideas and common sense. It would be a pity to miss it. So I summarized the whole video and added my opinion. The first thing to remind everyone is that the core research of the whole video is actually aimed at the health field, not fitness. Don't misunderstand some research results. On a sunny morning, the master ran to a scientist to do an experiment. Scientists thought it was a head start, ha ha smiled and said, in order to show sincerity, just run 10 mile. Don't worry, I'm not lying to you. I will run with you. The host thought about it with his eyes, and thought that this wave was not a loss, so he agreed. As a result, I ran and found that I was cheated. The scientist used to ride a bike with me. . . . The host thinks he is still too young with a 50-year-old face. . . After running, the host naturally picked up the coffee and horse manure that had been prepared long ago. . It is a kind of cake, and this program is not Baye's survival in the wilderness. . . ) and a banana to replenish energy, the scientist saw that the owner was eating happily, and suddenly jumped out and pointed out: According to your consumption just now, it will take another 55 minutes to run after eating these things. After listening, the host began to be incoherent: ah, ha, ha, ha, it's delicious to run for so long. I still don't eat. Oh, I can't help taking another bite. What should I do? Ah, ha ha ha. It turns out that I only consumed about 16 calories per minute after running for so long. Ah, I took another bite. Ha ha!
