Cranberries improve runners' performance thanks to an improved rate of muscle reoxygenation


A recent study highlights the benefits of a fruit rich in antioxidants, even for those who run or engage in aerobic activities. The fruit in question is the cranberry, known for its health benefits due to its richness in polyphenols, potent antioxidants that counteract oxidative stress in the body and can also oxygenate muscles.

Researchers from Concordia University in Montreal found that consuming a cranberry extract supplement for 28 days improved physiological performance markers in runners during both short (400 meters) and long (1500 meters) time trials. The study showed improved rates of muscle reoxygenation after the 28-day supplementation period compared to baseline for the 1500-meter run, suggesting that incorporating cranberries into the diet could delay the onset of muscle fatigue.

Additionally, it was found that the supplement was able to buffer post-exercise lactate response, indicating improved anaerobic metabolism for the 400-meter sprint. This natural aid offers athletes significant performance enhancement without the use of anabolic steroids.

Furthermore, cranberries offer various other health benefits, including improved memory after 12 weeks of daily consumption, a 9% reduction in LDL cholesterol levels, and a reduced risk of urinary tract infections and cystitis.

These results underscore the multitude of advantages associated with this small but potent fruit.
