, compared with supplementation with CIT alone. Thus, it appears that the interaction of NAC with NO or POMx reduces the POMx-induced actions of NO. This could be due to the formation of SNOs, which is driven by an increased NO:superoxide ratio. Although SNOs have been described as more stable NO forms, with

, 2016 ), and hence the greater effect of whey compared with collagen on activation of p70S6K is likely related to the increased leucine availability ( Apró et al., 2015a ; Moberg et al., 2014 ). Nonetheless, we acknowledge that direct assessment of MPS using stable isotope or deuterium methods would

Such analyzes have become increasingly

Lactate concentrations increased markedly from the onset of exercise and remained relatively stable thereafter (time: F = 62, p < .001), with significantly lower concentrations after CHO + BHB-ME than CHO (treatment: F = 10, p

By contrast, sodium assays are less stable, and none exist that precipitate sodium for quantitative measurements via colorimetry. At the time of absorbent patch removal, photos of microfluidic patches

No Effect of Acute Balenine Supplementation on Maximal and Submaximal Exercise Performance in Recreational Cyclists

al., 2000 ). An even more stable, yet naturally occurring, HCD with similar properties might be an even more suitable ergogenic aid. This creates opportunities for balenine because of its higher resistance toward CN1-mediated hydrolysis yielding a half-life of ≈30 min in human circulation (de Jager et
