Additionally these FVC s have been purported to induce metabolic alkalosis which perhaps may enhance the blood buffering capacity of an individual. Therefore the aim of this preliminary study was to profile the acid-base response after ingestion of an acute dose of fruit and vegetable extract Energised Greens EG Nottingham UK and compare it to a standard low dose g-kg 1 of sodium bicarbonate NaHCO3 . Findings As part of a randomized cross over design participants consumed 750 mL of water with either 9 g of EG manufacturer recommendations g-kg 1 of NaHCO3 or a placebo plain flour in opaque encapsulated pills following an overnight fast. Capillary samples were obtained and analyzed every 15 min for a period of 120 min following ingestion. Significant interactions p main effects for condition p and time p were evident for all acid-base variables pH HCO3 BE . Interactions indicated significant elevation in blood alkalosis for only the NaHCO3 condition when compared to both placebo and EG from 15 to 120 minutes. Conclusions Despite previous findings of elevated blood pH following acute mineral supplementation manufacturer recommended doses of EG do not induce any significant changes in acid-base regulation in resting males. Background The practice of manipulating acid-base balance for purposes of improving performance has been on going for nearly a century 1 . However enhancing blood buffering .
