Does real boxing increase serum levels of myoglobin and CK compared to shadow boxing in amateur boxers?
Traumatic muscular activity during real boxing leads to greater elevations in muscle damage biomarkers (myoglobin and CK) than simple muscular work.
Real boxing may cause greater muscle damage than shadow boxing; hypothesis-generating for injury risk in amateur training.
Muscular contraction, especially if it is protracted or particularly intense, causes notable changes in the substrate and enzymes involved. Marked changes have been found in the serum levels of myoglobin and CK in individuals subjected to very stressful physical work. This phenomenon has usually been attributed to the repeated and intense muscular traumas inherent in certain sporting activities. In the light of these facts, the authors decided to perform a study on amateur boxers aimed at measuring the difference between simple muscular work (shadow boxing) and traumatic activity (real boxing) in terms of their effect on a number of humoral parameters, especially myoglobin and CK. The serum levels of these two latter substances were found to increase more after real boxing than after shadow boxing.

Zuliani et al. (1985) conducted an observational in Amateur boxers. Real boxing (traumatic activity) vs. Shadow boxing (simple muscular work) was evaluated on Serum levels of myoglobin and CK. Real boxing increased serum levels of myoglobin and CK more than shadow boxing in amateur boxers.
