CarnoSyn Beta-Alanine Improves Exercise Performance in WomenResearchers at the University of Oklahoma set out to examine the effects of 28 days of

beta-alanine supplementation on the physical working capacity at fatigue threshold (PWCFT),

ventilatory threshold (VT), maximal oxygen consumption (VO2-MAX) and time to exhaustion

(TTE) in women. Twenty-two women were randomly assigned to either the beta-alanine

(CarnoSyn) or placebo group and tested by continuous, incremental cycle ergometry test to

exhaustion to determine the outcome measures. Results of this study showed that beta-

alanine supplementation delays the onset of neuromuscular fatigue and the ventilatory

threshold at submaximal workloads and increase in TTE during maximal cycle ergometry

performance, but had no affect on VO2-MAX. Researchers concluded that beta-alanine

supplementation improves submaximal cycle ergometry performance and TTE in young

women from an increased buffering capacity due to elevated muscle carnosine concentrations.
