Strong Support
Elite middle-distance runners with more fast-twitch muscle fibers (based on certain chemical levels) might be more likely to get overtrained after intense training, while those with more slow-twitch fibers tend to recover better and perform stronger after rest.

Muscle fiber typology is associated with the incidence of overreaching in response to overload training.
Cohort Study
Human
2020 Oct 1Runners with more fast-twitch muscle fibers (measured by carnosine) were more likely to get overtrained during heavy training and didn’t recover as well, while those with more slow-twitch fibers handled the load better and improved more after rest.
