Exercise recovery (4)
- Prostaglandin and myokine involvement in the cyclooxygenase-inhibiting drug enhancement of skeletal muscle adaptations to resistance exercise in older adults
PubMed ID: 23220477
COX‑inhibitor groups showed altered IL‑6/MuRF‑1 responses to training (markers linked to post‑exercise inflammation/proteolysis), reflecting AA‑pathway effects on recovery biology.
- Perioperative immunonutrition ameliorates the postoperative immune depression in patients with gastrointestinal system cancer (prospective clinical study in 42 patients)
PubMed ID: 15587331
Enteral immunonutrition accelerated immune recovery and normalized stress markers sooner, indicating faster physiological recovery after insult.
- Omega-3 fatty acids improve liver and pancreas function in postoperative cancer patients
PubMed ID: 15239141
Postoperative parenteral omega‑3 improved enzyme profiles and clinical recovery markers vs soybean oil — analogous anti-inflammatory/recovery effects.
- Fish oil and antioxidants alter the composition and function of circulating mononuclear cells in Crohn disease
PubMed ID: 15531659
Reduction in PGE2/IFN-γ from immune cells suggests a shift toward lower inflammatory tone that could speed recovery from exercise-induced inflammation.
