When you exercise, your muscles get tiny tears and your body sends inflammation to help fix them. If you take medicine to stop that inflammation, your muscles don't heal as well and you don't get as strong from your workouts.
See the scientific wording
Inflammation is an essential component of the muscle repair process, and suppressing inflammation impairs recovery and reduces muscular adaptations.

Cohort StudyAnimal2019
The study found that a laser treatment that reduces inflammation actually helped muscles heal better, which is the opposite of the claim that reducing inflammation is bad for recovery.
Cohort StudyAnimal2005
The study gave mice anti-inflammatory drugs after muscle injury and found that the muscles healed just fine, so stopping swelling didn't hurt recovery.
Quality-weighted scoring: we follow the GRADE framework — each study is rated High, Moderate, Low, or Very Low based on study design, methodology rigor, and risk of bias. A single high-quality RCT can outweigh several weaker observational studies.
Scores reflect study quality, not just count.
When a muscle gets hurt, the body sends special cells to clean up the damage. These cells release chemicals that are thought to tell muscle stem cells to wake up, multiply, and become new muscle fibers. This process is supposed to help the muscle heal and get strong again. However, giving drugs that block these chemicals did not stop the muscle from healing in the study, so the exact role of this response is not fully clear.

Mechanism
2 studiesWhen a muscle is hurt, the body sends in special cells to clean up and release chemicals that are thought to help build new muscle. But when we blocked these chemicals with drugs, the muscle still healed fine. So while this cleanup process happens, it might not be as important as we thought for getting better.

Skeletal muscle injury triggers an inflammatory response with infiltration of immune cells (neutrophils, macrophages) into the damaged tissue.
Inflammatory cells release cytokines and growth factors that are hypothesized to activate muscle satellite cells (muscle stem cells).
Activated satellite cells proliferate and differentiate into myoblasts.
Myoblasts fuse to form myotubes that mature into myofibers expressing myosin heavy chain.
Mature myofibers restore muscle structure and force-generating capacity.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review and Meta-Analysis of Randomized Controlled Trials on Anti-Inflammatory Use and Muscle Recovery
A systematic review and meta-analysis of RCTs comparing anti-inflammatory drugs (e.g., NSAIDs) versus placebo in healthy adults undergoing resistance training, measuring recovery markers (e.g., strength, muscle soreness) and muscular adaptations (e.g., hypertrophy) over at least 8 weeks.
Double-Blind Placebo-Controlled Trial of Ibuprofen on Muscle Recovery and Hypertrophy in Resistance-Trained Adults
A double-blind RCT with 100 healthy adults (aged 18-40) randomized to receive either ibuprofen (e.g., 400 mg three times daily) or placebo during a 12-week progressive resistance training program. Outcomes include muscle strength (1-RM), muscle cross-sectional area (MRI), and recovery markers (creatine kinase, perceived soreness) measured at baseline and post-intervention.
Prospective Cohort Study of Regular NSAID Use and Muscle Recovery in Recreational Athletes
A prospective cohort study following 500 recreational athletes (aged 20-50) who self-report NSAID use (frequency and dosage) over a 6-month training period. Measure changes in strength, muscle mass (DEXA), and self-reported recovery times, adjusting for confounders like training volume and diet.
In Vitro Study of Anti-Inflammatory Drugs on Muscle Satellite Cell Proliferation and Differentiation
Cultured human muscle satellite cells treated with varying concentrations of ibuprofen or other anti-inflammatory drugs, then assessed for proliferation, differentiation, and myotube formation compared to untreated controls. Measure gene expression of myogenic markers (e.g., MyoD, myogenin) and inflammatory cytokines.
