Stupid question before even reading the article: doesn’t exercise control blood sugar levels, which in turn reduces the surplus fuel supply of any cancer cell trying to grow?
The answer, they found, is that working muscles effectively outcompete tumors for the glucose supply. Because muscle contraction increases glucose uptake, exercise shifts metabolism, causing tumors to receive less of the fuel they need to grow.
Nailed it. Down to the use of the word “fuel”.
Nice one, you actually almost guessed what the study shows. I read the abstract and in general for melonomas and breast cancer in mice doing voluntary wheel running muscle glucose consumption went up and tumor consumption down. Tumor growth rate also slowed for the mice that ran.
Interesting study. Might need to start hitting the gym again then.
going to the gym is always a positive because you snowball into other healthy lifestyle changes like eating better and drinking more water, for example
I wish I had better access to one. I have a membership to LifeTime Fitness through my work and it’s a FANCY gym, but it’s 20 minutes from my house. With 2 small children, a quick hour workout becomes about 2 hours. I work out with my spin bike in the basement. I’ve also got a bench and adjustable dumbbells, but I miss the community of the gym.
