Pilot Work Studying Elite MMA Myonuclei                
 
 
We presented pilot research at this year's American College of Sports Medicine (ACSM) Annual Meeting in Boston, MA (see attached poster presentation). We found that muscle from an elite mixed martial artist (MMA) had >65% fast-twitch fibers and had more myonuclei (per fiber volume) compared to average adults. This pilot work provides 'proof of concept' for the methods of our future research. 
Thank you for backing this project! Remember, this research is for you. We will publish all findings in open access peer-reviewed journals.

Why Do Some Muscle Fibers Grow, Shrink, or Die Faster Than Others?

California State University, Fullerton

Ever wondered why some people build muscle faster than you? We know some people have more fast-twitch muscle fibers than others and muscle adaptations are regulated by your myonuclei (the cell components responsible for DNA replication, transcription, and protein synthesis). Thus, we believe the number of myonuclei differs between fiber types, and this explains much of how and why muscle grows and recovers at different rates between people, and between exercise programs!
