    Effect of Antioxidant Supplementation on Markers of Oxidative Stress and Muscle Damage after Strength Exercise: A Systematic Review
    (MDPI, 2022-02) Canals-Garzón, Cristina; Guisado-Barrilao, Rafael; Martínez-García, Darío; Chirosa-Ríos, Ignacio Jesús; Jerez-Mayorga, Daniel; Guisado-Requena, Isabel María
    Background: The purpose of this systematic review was to determine the effect of antioxidant consumption on markers of oxidative stress and muscle damage after performing a muscle strength exercise. Methods: The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed. Four databases were used: Scopus, PubMed, WOS and SportDiscus. Methodological quality was assessed using the PEDro scale. Results: A total of 1709 articles were retrieved and following duplicate removal and application of exclusion criteria seven articles were reviewed. Supplementation with pomegranate juice alleviates oxidative stress, taurine reduces muscle damage, melatonin protects the skeletal muscles, blueberries decrease oxidation and oats mitigate muscle damage. Conclusions: Acute administration of antioxidants immediately before or during an exercise session can have beneficial effects, such as delay of fatigue and a reduction in the recovery period. Administration of antioxidant susbtances may reduce muscle damage and oxidative stress markers. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.

    The severe training load of a competitive mesocycle may not be assimilated correctly by athletes, and can provoke endocrine imbalance, muscle damage and inflammation. Supplementation with antioxidants such as Phlebodium Decumanum (PHL) helps protect against such imbalances. The aim of this study is to analyse the effect of PHL on the fatigue during a precompetitive mesocycle in volleyball players. Twenty-four male volleyball players were divided into two groups (experimental and control). The experimental group was supplemented with three PHL capsules in the morning and three in the afternoon for 20 days. Blood samples were taken before training, at the end of the third week and at the end of the fourth week to evaluate creatine kinase (CK), interleukin 6 (IL-6), tumour necrosis factor-alpha (TNF-α), interleukin 10 (IL-10) and cortisol. The results show the control group, the third Cortisol were significantly increased (p < .05). In the experimental group, however, a significant increase (p < .05) was only observed in the third IL-10 value. In addition, significant differences (p < .05) were observed between the control and experimental groups in the second CK. Furthermore, there were moderate variations (effect size, ES > 0.5; 90% CI) in CK, IL-6 and TNF-α. In conclusion, PHL supplementation during a precompetitive mesocycle by volleyball players protects against the muscle damage, inflammatory modulation and cortisol response caused by fatigue. © 2023 Federacion Espanola de Docentes de Educacion Fisica.
