Abstract

Background: Purslane supplementation has anti-oxidative, anti-inflammatory, skeletal muscle-relaxant activities. However, it is unknown if the ingestion of purslane will affect the oxidative stress and cytokines in exercise-induced muscle damage. The aim of the present study was to examine the effect of purslane supplementation after high-intensity interval exercise (HIIE) on oxidative stress, cytokines, and muscle damage level in young athlete male runners. Methods: Seven healthy young male runners performed 2.5 km HIIE treadmill protocol. Athletes repeated this protocol following 10 days of purslane seed supplementation (1000 mg/day). Blood samples were collected at baseline and following HIIE protocol and analyzed for oxidative stress (9-HODE and 13-HODE), cytokines (IL-17, and TNF-α), and muscle damage (LDH) biomarkers. Results: At baseline and following HIIE protocol, 9-HODE, 13-HODE, IL-17, TNF-α, LDH levels were significantly (p < 0.001) lower after purslane supplementation in compared to before purslane supplementation. HIIE protocol induced a significant increase in 9-HODE, 13-HODE, IL-17, TNF-α, and LDH before and after purslane supplementation. Conclusion: Purslane seed supplementation was able to reduce oxidative stress (9-HODE, 13-HODE), proinflammatory cytokines (IL-17 and TNF-α), and muscle damage (LDH) in male runners after HIIE performance compared to baseline levels. After 10 days of supplementation, the levels were reduced compared to levels pre-supplementation but not after HIIE supplementation in supplemented athletes. © 2019, Springer-Verlag Italia S.r.l., part of Springer Nature.
