BackgroundCocoa flavanols (CF) can stimulate vasodilation by improved nitric oxide (NO) synthesis and have antioxidant and anti-inflammatory capacities. This study aimed to examine whether acute CF intake can affect exercise-induced changes in antioxidant capacity, oxidative stress, inflammation and NO production, as well as exercise performance and recovery in well-trained cyclists.MethodsTwelve well-trained male cyclists (mean ± SD age, VO2max: 30 ± 3 years, 63.0 ± 3.5 ml/kg/min) participated…

Effects of Short-Term Green Tea Extract Supplementation on VO2 Max and Inflammatory and Antioxidant Responses of Healthy Young Men in a Hot Environment
TLDR
The consumption of green tea supplements 90 min before aerobic exercise may decrease inflammation and oxidative stress factors and improve VO2 Max in summer.
A single dose of purple grape juice improves physical performance and antioxidant activity in runners: a randomized, crossover, double-blind, placebo study
TLDR
The single-dose intake of purple grape juice demonstrated an ergogenic effect in recreational runners by increasing run time to exhaustion and increasing antioxidant activity.
Effects of ascorbic acid supplementation on oxidative stress markers in healthy women following a single bout of exercise
TLDR
Supplementation with ascorbic acid prior exercise improves antioxidant power but does not prevent muscle damage.
Acute (-)-Epicatechin Consumption: Effects on Local Vasodilation Following Resistance Exercise and High-Intensity Exercise Performance
TLDR
Under the conditions of the current studies, acute (-)-epicatechin supplementation did not augment vasodilation in combination with resistance exercise, nor did it increase exercise performance in humans.
The influence of different concentrations of flavanol chocolate bars under acute supplement conditions on exercise and performance
TLDR
It is plausible that longer flavanol supplementation periods might have greater accumulative effects and thus may potentially elicit a larger effect on exercise and performance.
Flavanol-Rich Cacao Mucilage Juice Enhances Recovery of Power but Not Strength from Intensive Exercise in Healthy, Young Men
(1) Background: Mucilage within cacao pods contains high levels of polyphenols. We investigated whether consumption of cacao juice enhances the recovery of muscle function following intensive knee…
Effects of Functional Phenolics Dietary Supplementation on Athletes’ Performance and Recovery: A Review
TLDR
Overall, the reports show that phenolics exert important benefits on exercise-induced muscle damage as well as play a biological/physiological role in improving physical performance.
The effects of cocoa flavanols on indices of muscle recovery and exercise performance: a narrative review
Abstract Exercise-induced muscle damage (EIMD) is associated with oxidative stress and inflammation, muscle soreness, and reductions in muscle function. Cocoa flavanols (CF) are (poly)phenols with…
Effect of food sources of nitrate, polyphenols, L-arginine and L-citrulline on endurance exercise performance: a systematic review and meta-analysis of randomised controlled trials
TLDR
Foods rich in polyphenols and nitrate provide trivial benefits for endurance exercise performance, although these effects may be food dependent.
Effect of Cocoa Products and Its Polyphenolic Constituents on Exercise Performance and Exercise-Induced Muscle Damage and Inflammation: A Review of Clinical Trials
TLDR
The retrieved data indicate that acute, sub-chronic, and chronic cocoa polyphenol intake may reduce exercise-induced oxidative stress but not inflammation, while mixed results are observed in terms of exercise performance and recovery.

TLDR
Improvements in maximum work achieved and VO2 max may be due to DC activation of upstream control systems and enhancement of SkM mitochondria efficiency.
Acute consumption of flavanol-rich cocoa and the reversal of endothelial dysfunction in smokers.
Regular dark chocolate consumption's reduction of oxidative stress and increase of free-fatty-acid mobilization in response to prolonged cycling.
TLDR
It is suggested that regular DC intake is associated with reduced oxidative-stress markers and increased mobilization of free fatty acids after exercise but has no observed effect on exercise performance.
The effect of acute pre-exercise dark chocolate consumption on plasma antioxidant status, oxidative stress and immunoendocrine responses to prolonged exercise
TLDR
Acute DC consumption may affect insulin, glucose, antioxidant status and oxidative stress responses, but has minimal effects on immunoendocrine responses, to prolonged exercise.
Acute Antioxidant Supplementation Improves Endurance Performance in Trained Athletes
TLDR
There was considerable evidence for substantial positive treatment effects for TTF and the other performance-related variables (excluding [BLa] at 95% PPO) and the mechanisms underlying the observed effects.
The Effects of Acute Post Exercise Consumption of Two Cocoa-Based Beverages with Varying Flavanol Content on Indices of Muscle Recovery Following Downhill Treadmill Running
TLDR
It is suggested that the acute addition of cocoa flavanols to low-fat chocolate milk offer no additional recovery benefits and subsequent exercise performance, creatine kinase, muscle tenderness, force, and self-perceived muscle soreness are unchanged.
The effect of green tea extract supplementation on exercise-induced oxidative stress parameters in male sprinters
TLDR
Supplementation with GTE prevents oxidative stress induced by RST in sprinters, and GTE supplementation does not seem to hinder training adaptation in antioxidant enzyme system.

Effects of 7 days of arginine-alpha-ketoglutarate supplementation on blood flow, plasma L-arginine, nitric oxide metabolites, and asymmetric dimethyl arginine after resistance exercise.
TLDR
No(2) Platinum increased plasma L-arginine levels; however, the effects observed in hemodynamics, brachial-artery blood flow, and NOx can only be attributed to the resistance exercise.
