Free radical production during exercise contributes to fatigue and antioxidant treatment might be a valuable therapeutic approach. In this study, the antioxidant properties of green tea polyphenols (GTP) were evaluated in vitro through hydroxyl radical-scavenging activity, and ascorbic acid was used as reference compound. The study showed that GTP possessed more pronounced hydroxyl radical scavenging activity than ascorbic acid, and the scavenging activity increased with increasing of the… Expand

Anti-Fatigue Effect of Green Tea Polyphenols (-)-Epigallocatechin-3-Gallate (EGCG)
TLDR
The data showed that EGCG prolonged exhaustive swimming time, decreasing the levels of blood lactic acid, serum urea nitrogen, serum creatine kinase and malondialdehyde, which were accompanied by corresponding increase in liver and muscle glycogen contents, and superoxide dismutase, catalase, and glutathione peroxidase activities.

Research Article Antioxidant and Antifatigue Activities of Ophiopogon japonicus Extracts in Exercised Rats
This study evaluated the effective of antioxidant and antifatigue potential of Ophiopogon japonicus extracts (OJE) in exercised Sprague Dawley rats. The OJE was prepared and measured its antioxidantExpand
Anti-Fatigue and Antioxidant Activity of the Polysaccharides Isolated from Millettiae speciosae Champ. Leguminosae
TLDR
Findings strongly suggested that MSP was able to alleviate physical fatigue by increasing energy resources and decreasing accumulation of detrimental metabolites and the antioxidant activity may crucially contribute to the observed anti-fatigue effect of MSP. Expand
Antioxidant and Anti-fatigue Activities of Seed Oil from the Berries of Three Indigenous Plants in Tibetan Plateau
TLDR
The antioxidant assay results indicated that the seed oil obtained from HRL was significantly more active in scavenging free radicals compared to the other seed oils, indicating that such seed oil supplements could prevent lipid oxidation in forced swimming mice. Expand
The traditional drug Gongjin-Dan ameliorates chronic fatigue in a forced-stress mouse exercise model.
TLDR
The clinical relevance of Gongjin-Dan regarding anti-chronic fatigue properties is supported and the underlying mechanisms involve attenuation of oxidative and inflammatory reactions in muscle and regulation of the stress response through the hypothalmo-pituitary-adrenal axis. Expand
THE EFFECT OF GIVING RED GUAVA FRUIT JUICE TOWARDS HAEMOGLOBIN AND VO2MAX CONTENTS ON MAXIMUM PHYSICAL ACTIVITY
TLDR
Based on the results of data analysis, it found that the red guava juice during training program can increase Hb and VO2max levels in maximum physical activity. Expand
Antioxidant and Anti-Fatigue Constituents of Okra
Okra (Abelmoschus esculentus (L.) Moench), a healthy vegetable, is widely spread in tropical and subtropical areas. Previous studies have proven that okra pods possess anti-fatigue activity, and theExpand

TLDR
Green tea consumption significantly enhances the activity of α-amylase and salivary antibacterial capacity in taekwondo athletes, following intensive training. Expand
Antioxidant and Antifatigue Activities of Polygonatum Alte-lobatum Hayata Rhizomes in Rats
TLDR
EPA could be a potential agent with an anti-fatigue pharmacological function and dose-dependently increased endurance running time to exhaustion and superoxide dismutase activity and total antioxidant ability of blood and decreased serum urea nitrogen and malondialdehyde levels after exercise. Expand

Effects of palm vitamin e supplementation on exercise-induced oxidative stress and endurance performance in the heat.
TLDR
Although tocotrienol-rich palm vitamin E supplementation decreased lipid peroxidation at rest and, to some extent, during exercise in the heat, as evident from the lower MDA levels, it however did not enhance endurance running performance or prevent exercise-induced muscle damage or influenced body core temperature or plasma volume changes during exercise during the heat.

Antioxidant effects of green tea polyphenols on free radical initiated peroxidation of rat liver microsomes.
TLDR
Kinetic analysis of the antioxidation process demonstrates that these green tea polyphenols (GOHs), especially EC and ECG which bear ortho-dihydroxyl functionality, are good antioxidants for microsomal peroxidation. Expand
Effect of nutritive and tonic crude drugs on physical fatigue-induced stress models in mice.
TLDR
The present results indicate that the NTDs produced an anti-fatigue effect on the decreased locomotor activity after forced walking and immobility induced by electric stimulation, however, the crude drugs were not effective in improvingimmobility after sleep deprivation or immobilization stress.
