Lactobacillus plantarum TWK10, the probiotic in Superman's belly
A beneficial bacteria, one that microbiologists have found in Taiwanese pickled cabbage, reduces body fat, stimulates the growth of muscle tissue and boost muscle strength and endurance capacity. Researchers at National Taiwan Sport University write about this in Nutrients. The Taiwanese did experiments on mice.
At the end of the period the researchers measured the amount of strength the mice had in their paws, and how long the animals could swim in an aquarium until they could no longer keep their heads above water.
After the mice had swum the researchers found less lactic acid [CK], ammonia [NH3] and creatine kinase in the blood of the animals that had been given probiotics. Click on the figure below for a larger version.
The body composition of the mice had changed for the better. Their relative fat mass had declined - there had been a decrease in the epididymal fat pad [EFP] - and at the same time their relative muscle mass had increased, as shown by the increase in weight of the gastrocnemius and soleus.
"We found that Lactobacillus plantarum TWK10 supplementation could enhance glucose utilization to increase endurance exercise time by increasing the number of gastrocnemius type I muscle fibers", the researchers wrote.
"We provide evidence that Lactobacillus plantarum TWK10 affects biochemical features with long-term aerobic swimming. For future investigations, Lactobacillus plantarum TWK10 could be used in humans who focus on aerobic endurance training for protective and health purposes."
"In addition, data in humans supporting the existence of such interplay are lacking. Because humans have different lifestyles, behaviors, diets, and many environmental factors that influence their microbiomes, future studies should be performed in humans to validate the concepts based on animal models."
