@article { , title = {Dietary β-alanine intake assessed by food records does not associate with muscle carnosine content in healthy, active, omnivorous men and women.}, abstract = {β-alanine (BA) is one of the most widely used sport supplements, due to its capacity to improve high intensity exercise performance by increasing muscle carnosine (MCarn) content, and consequently, the buffering capacity of the muscle. BA is also available in a variety of animal foods, but little is currently known about the influence of dietary BA intake on MCarn. The aim of the current study was to compile a detailed summary of available data on the BA content of commonly consumed foods, and to explore whether associations could be detected between self-reported dietary BA intake and skeletal MCarn in a group of 60 healthy, active, omnivorous men and women. Dietary BA intake was assessed via 3-day food records and MCarn content assessed by high performance liquid chromatography. A series of univariate and multivariate linear regression models were used to explore associations between estimated dietary BA and MCarn. No evidence of associations between dietary BA intake and MCarn were identified, with effect sizes close to zero calculated from models accounting for key demographic variables (f2 ≤ 0.02 for all analyses). These findings suggest that capacity to increase MCarn via dietary strategies may be limited, and that supplementation may be required to induce increases of the magnitude required to improve performance.}, doi = {10.1123/ijsnem.2022-0236}, eissn = {1543-2742}, issn = {1526-484X}, issue = {3}, journal = {International journal of sport nutrition and exercise metabolism}, note = {INFO COMPLETE (Now fully published, checked and uploaded 2/5/2023 LM; now online; not yet assigned to issue 05.04.2023 GB -- Info via contact of acceptance 14/3/2023 LM) PERMISSION GRANTED (version = AAM; embargo = none; licence = Pub's Own; SHERPA = https://v2.sherpa.ac.uk/id/publication/12248 14/3/2023 LM) DOCUMENT READY (AAM rec'd from contact 14/3/2023 LM) ADDITIONAL INFO - Contact: Paul Swinton Set Statement (Accepted author manuscript version reprinted, by permission, from International Journal of Sport Nutrition and Exercise Metabolism, 2023, 33(3), pages 133-140, https://doi.org/10.1123/ijsnem.2022-0236. © Human Kinetics, Inc.)}, pages = {133-140}, publicationstatus = {Published}, publisher = {Human Kinetics}, url = {https://rgu-repository.worktribe.com/output/1912089}, volume = {33}, keyword = {Health & Wellbeing, β-alanine, Diet, Carnosine, Supplement, Nutrition, Food, Buffering, Histidine containing dipeptides, Meat}, year = {2023}, author = {Rezende, Nathalia Saffioti and Bestetti, Giulia Cazetta and Farias de Oliveira, Luana and Mazzolani, Bruna Caruso and Smaira, Fabiana Infante and Dumas, Alina and Swinton, Paul and Saunders, Bryan and Dolan, Eimear} }
