#022 [EN] - Muscle Fiber Typology with Freek Van de Casteele Exercise Inside Out
-
- Wissenschaft
"If you know the fiber type composition of your athlete, you already know how to manipulate your training variables."
Muscle fiber types are frequently discussed in various field of exercise sience. Their typology seems to influence performance, training and pacing in athletes. But...
- What kind of muscle fibers do we have?
- How are fiber types related to exercise performance?
- How can fiber types be determined? AND
- (How) Can I change my fiber typology?
I discussed these interesting questions with Freek Van de Casteele from Ghent University. Freek is currently finishing his PhD on muscle fiber typology and examined non-invasive methods to determine muscle fiber composition. We talked about the basics as well as the latest research on how myotypes are related to performance.
