Muscle damage induced by inertial exercise performed on a flywheel device was assessed through the serum evolution of muscle enzymes, interleukin 6, and fiber type‐specific sarcomere proteins such as fast myosin ( FM ) slow SM ). We hypothesized that model could be constructed measuring concentration following exercise, according to their molecular weight compartment in which they are located. Moreover, , type fibers affected assessed. Serum profiles were registered before 24, 48, 144 h after 10 healthy recreationally active young men. Creatine kinase CK ‐myocardial band isoenzyme increased early (24 h) returned baseline values 48 h. late (48 remained elevated post‐exercise. The increase enzymes suggests membrane permeability both fibers, reveals disruption well fibers. Consequently, adopted biomarker damage.
