1 . It’s no surprise that there’s a link between exercise and mental health. But scientists have now made it official: research has found a direct connection between movement and mood. Why does exercise hold so many benefits for our mental health?
When our muscles tighten, chains of amino acids (氨基酸) called myokines (肌细胞因子) are released into the bloodstream.
A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care.

I had been swimming competitively for five years but after such a long time, I was ready to quit. I was often the only African American at the swimming competitions and our team couldn’t afford good uniforms. However, my number-one reason for wanting to quit was that I kept receiving “Honorable mentions” (安慰奖). Any athlete knows that you don’t want to have a bookshelf full of “Honorable Mentions”, which you get just because you showed up.
One summer day, the day before a big swim meet, I decided to break the news to my grandma that I was quitting the swim team. When I told her, she looked me in the eye and said, “Baby, remember these words: ‘Quitters never win and winners never quit.’ Your grandmother didn’t raise losers or quitters. You go to that swim meet tomorrow, and you swim like you are a grandchild of mine, you hear?” I was too afraid to say anything but “Yes, ma’am.”
The next day we arrived at the swim meet late, missing my group of swimmers in the 15/16 age group. My coach insisted that I be allowed to swim with the older group. I knew that she was including me in the race so that our journey to the meet would not be wasted, and she had no expectations whatsoever that I would come in anything but eighth place and only that, because there weren’t nine lanes.
As I was mounting the board, all the other girls looked at me. I quickly noticed that these girls were here to do one thing—beat me! All of a sudden, my grandma’s words rang in my head. “Quitters never win and winners never quit. You swim like you are a grandchild of mine. Quitters never win and winners never quit.” “Yes, Grandma, I will swim like I am a grandchild of yours,” I said to myself.
