Multiday Pomegranate Extract Supplementation Decreases Oxygen Uptake During Submaximal Cycling Exercise, but Cosupplementation With N-acetylcysteine Negates the Effect

Emma M. Crum, Matthew J. Barnes, and Stephen R. Stannard

, 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

The Effect of 1 Week of a Multi-ingredient Dietary Preworkout Supplement on Resting and Postacute Resistance Exercise Vascular Function

The ultrasound was set to triplex to simultaneously measure arterial diameter (B-mode), Doppler (blood flow velocity), and electrocardiogram. The flow signals were corrected at an insonation angle

Whey Protein Augments Leucinemia and Postexercise p70S6K1 Activity Compared With a Hydrolyzed Collagen Blend When in Recovery From Training With Low Carbohydrate Availability

, 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

Sweating Rate and Sweat Chloride Concentration of Elite Male Basketball Players Measured With a Wearable Microfluidic Device Versus the Standard Absorbent Patch Method

Lindsay B. Baker, Michelle A. King, David M. Keyes, Shyretha D. Brown, Megan D. Engel, Melissa S. Seib, Alexander J. Aranyosi, and Roozbeh Ghaffari

chloride assay is well established, and the chemical reaction is robust at various ambient temperatures. 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

Sarah de Jager, Stefaan Van Damme, Siegrid De Baere, Siska Croubels, Ralf Jäger, Martin Purpura, Eline Lievens, Jan G. Bourgois, and Wim Derave

 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
