Even without losing weight, intense wrestling-style training can cause measurable signs of muscle damage in wrestlers.
Scientific Claim
High-intensity sport-specific training alone is associated with an increase in muscle damage biomarkers—including myoglobin, aldolase, creatine kinase, aspartate aminotransferase, alanine aminotransferase, and lactate dehydrogenase—in male wrestlers.
Original Statement
“A substantial increase in analyzed biomarkers was evident in both phases (P1 and P2).”
Evidence Quality Assessment
Claim Status
overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The abstract uses 'increase' as if causal, but without control for confounders or randomization verification, causation cannot be confirmed. Verb strength must be conservative.

Acute muscle damage as a metabolic response to rapid weight loss in wrestlers
Even without losing weight, just doing intense wrestling training made the wrestlers' muscles get more damaged, as shown by higher levels of certain blood markers.
