topicN-Acetylcysteine Exercise Recovery Randomized Trial
claim1 Aging is characterized by progressive physiological decline, including loss of skeletal muscle mass and function (Sarcopenia), reduced mitochondrial efficiency, and increased oxidative stress, all of which contribute to frailty and diminished quality of life in older adults ().

topicN-Acetylcysteine Exercise Recovery Randomized Trial
claimEvidence is organized by outcome domain—training adaptations versus acute performance/recovery—and analyzed through moderators that matter in real programs: class of antioxidant, dose, timing relative to key sessions, training phase, and environmental stress.
