Curcumin Versus Ibuprofen for Exercise-Induced Muscle Damage in Physically Active Women (CURACTIVE)
Comparative Efficacy of Oral Curcumin Supplementation Versus Ibuprofen on Exercise-Induced Muscle Damage, Inflammation, Oxidative Stress, and Sports Performance in Physically Active Women: A Randomized Double-Blind Placebo-Controlled Trial
xercise-induced muscle damage (EIMD) is a common consequence of unaccustomed or high-intensity exercise and is characterized by muscle soreness, impaired physical performance, inflammation, oxidative stress, and increased circulating biomarkers of muscle damage. Non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, are frequently used to alleviate these symptoms, although their repeated use may be associated with adverse effects. Curcumin, a natural polyphenol with antioxidant and anti-inflammatory properties, has emerged as a potential nutritional strategy to support post-exercise recovery.
This randomized, double-blind, placebo-controlled trial aims to compare the effects of oral curcumin supplementation and ibuprofen administration on exercise-induced muscle damage in physically active women. The study evaluates clinical outcomes, physical performance, biomarkers of muscle damage, inflammation, oxidative stress, and other health-related biomarkers to determine whether curcumin may represent a safe and effective nutritional alternative for promoting recovery after eccentric exercise.

详细说明
Exercise-induced muscle damage (EIMD) following eccentric exercise is characterized by structural disruption of skeletal muscle fibers accompanied by transient inflammation, oxidative stress, delayed-onset muscle soreness, and impaired physical performance. Although these responses are considered part of the normal adaptive process, excessive muscle damage may delay recovery and impair subsequent training or competition.
Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used by athletes to reduce post-exercise pain and inflammation. However, repeated NSAID use has been associated with gastrointestinal, renal, and cardiovascular adverse effects, highlighting the need for safe nutritional alternatives capable of supporting recovery without interfering with physiological adaptation.
Curcumin, the principal bioactive polyphenol derived from Curcuma longa, exhibits antioxidant, anti-inflammatory, and cytoprotective properties through modulation of multiple molecular pathways involved in redox homeostasis and inflammatory signaling. Experimental and clinical studies suggest that curcumin may attenuate exercise-induced muscle damage by reducing oxidative stress, inflammatory responses, and muscle soreness, although evidence remains inconsistent and direct comparisons with NSAIDs are scarce.
The objective of this randomized, double-blind, placebo-controlled trial is to compare the efficacy of oral curcumin supplementation with ibuprofen and placebo in physically active women following eccentric exercise. The study evaluates clinical recovery, physical performance, biomarkers of muscle damage, inflammatory and oxidative stress biomarkers, and additional health-related biomarkers in order to characterize the physiological effects of curcumin supplementation and determine its potential role as a nutritional strategy for exercise recovery.
