<italic>Study aim</italic>: Dietary and non-dietary weight loss methods are highly prevalent among combat sports athletes (CSA). Most CSA undergo rapid weight loss (RWL) usually a week before the competition to reduce their body mass and thus compete in the lowest weight category possible. The objective of the study was to distinguish the impact of high-intensity sport-specific training (HISST) combined with RWL (phase 1 – P1) on muscle damage markers as well as the effects of HISST alone (phase 2 – P2).
<italic>Material and methods</italic>: This crossover study was carried out on 12 male wrestlers. It consisted of initial measurement (IM), high-intensity training combined with RWL of 5% (P1), and high-intensity training without RWL (P2). After each phase, muscle damage markers were measured, including myoglobin, aldolase, creatine kinase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase.
<italic>Results</italic>: A substantial increase in analyzed biomarkers was evident in both phases (P1 and P2). However, higher levels of almost all biomarkers were observed in the phase that included RWL compared to the second phase, with a greater significance level.
<italic>Conclusions</italic>: Our study revealed that 5% RWL combined with HISST impacted the assessed biomarkers to a greater extent than HISST alone, thus providing strong evidence of the influence of RWL on muscular damage in wrestlers. In order to minimize the adverse health-related effects induced by weight reduction, coaches and athletes should use caution when considering weight management methods.
