Abstract: The purpose of this study was to estimate the effects of ribose
supplementation on interval anaerobic performance and fatiguing substance
concentrations. The study cohort consisted of physically active, young male
volunteers (n=15). With a double-blind cross over study design, each
participant completed two all-out anaerobic exercise sessions, one week apart,
one by supplementing maltodextrine and the other by supplementing ribose (150
mg/kg in each test). Two repetitions of 30-s maximal performance with a 4-min
interval were completed. Blood samples were taken at rest and five minutes
after the second sprint repetition. Neither the biochemical parameters: pH
(−0.32 ± 0.09 vs. −0.26 ± 0.11), lactate (La) (13.8
± 1.9 vs. 13.3 ± 2.7 mM, ammonia (423 ± 190 vs. 404
± 166 μ mol/L), inorganic phosphate (Pi) (0.68 ± 0.53 vs. 0.72
± 0.63 mM) nor the anaerobic output (746.2 ± 82.5 vs. 760.2
± 86.8 watts) were affected by placebo and ribose supplementations
significantly (p> 0.05). In conclusion, based on this protocol, anaerobic
performance and/or biochemical status are not affected by ribose
supplementation.
