There is a continuing research interest in the muscle fiber type composition ( MFTC ) of athletes. Recently, carnosine quantification by proton magnetic resonance spectroscopy 1 H‐ MRS was developed as new non‐invasive method to estimate . This cross‐sectional study aims better understand estimated relation (a) different disciplines within one sport; (b) cyclic sport exercise characteristics; (c) within‐athlete variability; and (d) athlete level. A total 111 elite athletes (74 runners, 7 triathletes, 11 swimmers, 14 cyclists 5 kayakers) 188 controls were recruited measure gastrocnemius deltoid Within disciplines, divided into subgroups (sprint‐, intermediate‐, endurance‐type). The used reference population allow expression athletes’ data Z ‐scores. sports, endurance‐type systematically showed lowest ‐score compared sprint‐type athletes, with intermediate‐type always situated between. Across sports content strongest significant correlation movement frequency R = 0.86, P 0.001). Both between divergent sprint‐ Cyclic frequency, rather than duration came out most determining factor for optimal
