INFLAMMATION
Multiomics methods such as metabolomics and proteomics are used by sports nutrition investigators to capture the system-wide influence of nutritional interventions before and after stressful exercise workloadsEmerging evidence indicates that lipid mediators are involved in initiating, mediating, and resolving exercise-induced muscle tissue injury, inflammation, and metabolic stressThe purpose of this study was to extend these findings from endurance athletes to relatively untrained individuals using plasma oxylipins as the primary outcome measure. This study determined if supplementation with blueberries (1 cup/day, 14 d before exercise and 4 days after) compared to placebo could mitigate muscle soreness and damage and improve inflammation resolution in response to an acute, 90-min bout of eccentric exercise. Common exercises that cause an eccentric muscle contraction include going down several flights of stairs, running downhill, lowering weights, stop-and-go sports like basketball and tennis, and the downward motion of squats, push-ups, or pull-ups. Eccentric muscle activity, especially in relatively untrained individuals, causes extensive and prolonged muscle damage and soreness
