catalase, glutathione peroxidase, and superoxide dismutase, which can modulate oxidative damage 22 and, theoretically, DOMS and impairments in muscle function associated with excess oxidant generation. Although CURC activates Nrf2, 23 this effect has not been reported alongside markers of muscle damage

) ↑ Glutathione at 2 weeks ( p  = .05) ↓ Fibrotic size at 6 weeks (5 mg; p  = .013) Vitamin C injection enhances antioxidant action, leading to reduced tendon adhesion and restoration of glutathione levels. There is a greater response for gliding resistance and fibrotic size with a lower dose (5 mg). R1: high R2

Nrf2 regulates antioxidant genes, such as catalase, superoxide dismutase, and glutathione peroxidase, that interact with oxidant mediators and counter redox dyshomeostasis ( Sivandzade et al., 2019
