Neither this article, nor the actual paper it is based on (<a href="https://www.nature.com/articles/d41586-024-02731-9#:~:text=The%20molecule%20lactate%20is%20a,cells%20to%20generate%20their%20energy" rel="nofollow">https://www.nature.com/articles/d41586-024-02731-9#:~:text=T...</a>.) has any mention of exercise, and the title here seems to be editorialised to add in "Metabolic byproduct of anaerobic exercise".<p>Just because lactate is produced from anaerobic exercise and this study found that lactate was used by the cancer cells, doesn't automatically follow that the cancer cells can use the lacate produced from exercise.
This is all I can read. Does the paper imply
that any exercise is bad?<p>“ Lactate helps cancer cells resist chemotherapy
The molecule lactate is a waste product of the metabolism of sugar without oxygen — a metabolic pathway preferentially used by cancer cells to generate their energy. Metabolomics analysis reveals that lactate in tumour cells promotes resistance to chemotherapy, and sheds light on the molecular mechanism that underlies this unexpected role of lactate in cancer”
