Out of shape? Ribose turns you into a better athlete
Athletes who are not fit may benefit from supplementation with the sugar ribose. After intensive exercise they will experience less muscle damage, and simultaneously the supplement will enable them to perform better during short and explosive movements. A sponsored study, published by exercise scientists at Montana State University in the Journal of the International Society of Sports Nutrition, suggests this.
What is ribose?
Ribose molecules are ound in the information-carrying molecules in the cell nucleus. The RNA molecule, that passes instructions from the DNA to the cell, consists for a large part of ribose. A variant of ribose, deoxyribose, is an important building block of DNA.
Supplement manufacturers claim that ribose can accelerate the recovery of muscle cells during and after intense exertion. The extent to which these claims are correct is still not clear, as study outcomes are not consistent.
Study
After the interval training, the subjects had to cycle as hard as possible for 2 minutes. In that last part of the session, the researchers determined how much power [say: speed] the subjects could develop.
On another occasion, the researchers repeated the experiment. Then they gave their subjects glucose [another word: dextrose].
Results
After the session, the researchers found less creatine kinase in the blood of the non-fit subjects if they had used ribose. In this group, ribose apparently reduced muscle breakdown. In the fit subjects, ribose had no effect - again.
Conclusion
"The analysis revealed that the lower VO2 value subjects had a significant improvement in performance, lower changes in creatine kinase, and lower rating of perceived exertion was recorded with D-ribose compared to dextrose."
"Assessment of metabolic serum parameters did not reflect any appreciable differences between the treatments, not clearly demonstrating a potential mechanism accounting for this benefit."
"In summary, D-ribose demonstrated a performance, perceptual, and serum benefits in the lower fitness adult subjects undergoing high intensity exercise. The stress of high intensity exercise has the potential to be benefited with supplementation of D-ribose around these exercise sessions."
"Future studies are needed to elucidate the mechanism(s) of action of D-ribose ingestion and exercise."
