Matcha meets muscle- green tea powder boost strength and ease fatigue

Matcha green tea, a vibrant powdered form of green tea rich in antioxidants, amino acids, and polyphenols, may offer more than a morning energy boost. This randomized controlled study explored whether daily matcha consumption could enhance the physical and physiological adaptations to resistance training in healthy young men. Over 8 to 12 weeks, participants consuming matcha twice daily showed improvements in muscle mass, reduced exercise-induced fatigue, and lowered stress biomarkers compared to a placebo group.

In the short term, matcha intake was associated with lower subjective fatigue after just one week of training and a trend toward greater leg strength gains. Over the longer term, those in the matcha group exhibited greater increases in skeletal muscle mass and significantly lower salivary cortisol levels—a biomarker linked to physical and psychological stress. These findings suggest that matcha’s bioactive compounds may support recovery and enhance training adaptation.

Gut microbiota analysis revealed that matcha altered the abundance of specific beneficial bacteria, including Ruminococcus, Oscillospira, and Butyricimonas, which positively correlated with strength improvements. These microbes are known for their role in short-chain fatty acid production and anti-inflammatory effects, hinting at a gut-muscle axis influenced by dietary antioxidants and fiber.

While visual function and oxidative stress markers showed minimal change, the combined anti-fatigue, anabolic, and gut-modulating properties of matcha point to its potential as a natural ergogenic aid. Future studies should explore its impact on diverse populations and its role in long-term muscle and metabolic health.
