Probiotic bacteria Bifidobacterium longum OLP-01 makes well-trained runners even faster

A few years ago, microbiologists in Taiwan discovered a bacterium that could make mice more muscular, leaner, fitter and stronger. The thing was called Bifidobacterium longum OLP-01. Today we read - somewhat belatedly, we admit - a human study in which trained runners were given supplements with that probiotic. Their scores on the good old Cooper test improved as a result.

Studie
In 2020, researchers from Taipei Medical University in Taiwan published a trial in Nutrients in which 21 young trained runners participated as test subjects. All subjects were 20-30 years old and trained in an identical way for 3 weeks. Then they did not train for 2 weeks.

The researchers divided their subjects into 2 groups, a placebo group and an experimental group. The subjects in the latter group took a capsule with 5 x 10-9 colony forming units OLP-01 with three meals a day. In total, the subjects consumed 15 x 10-9 colony forming units OLP-01 per day.

Before the supplementation started and on the last day, the researchers tested the fitness of the subjects with the Cooper test. In simple terms, this means that the subjects had to run as far as possible for 12 minutes.

Results
The total distance the subjects could run decreased by 56 meters in the placebo group. In the OLP-01 group it increased by 105 meters.

The lean body mass decreased slightly in both groups, but only in the placebo group was this decrease statistically significant. The researchers therefore assume that supplementation with OLP-10 protects muscle mass against breakdown.

The researchers found no indications of adverse effects of supplementation.

Conclusion
"OLP-01 supplementation combined with regular exercise for three weeks and rest for two weeks can still eectively improve endurance exercise performance [...] in well-trained middle- and long-distance runners", write the researchers.

"OLP-01 can be used as a sports nutrition supplement, especially for athletes, to improve exercise performance."
