The aim of this study was to determine the individual variability in time to peak pH after the consumption of a 300mg . kg -1 dose of sodium bicarbonate (NaHCO 3 ). Seventeen active males volunteered to participate in the study (mean ± SD: age 21.38 ± 1.5y; mass 75.8 ± 5.8kg; height 176.8 ± 7.6cm). Participants reported to the laboratory where a resting capillary blood sample was taken aseptically from the fingertip. After this, 300 mg . kg -1 of NaHCO 3 in 400ml of water with 50ml of flavoured cordial was ingested.Participants then rested for 90 min during which repeated blood samples were procured at 10 minute intervals for 60 mins and then every 5 min until 90 min. Blood pH concentrations were measured using a blood gas analyser. Results suggested that time to peak pH (64.41±18.78 min) was highly variable with a range of 10-85 min and a coefficient of variation of 29.16%. A bi-modal distribution occurred, at 65 and 75 min. In conclusion, researchers and athletes, when using NaHCO 3 as an ergogenic aid, should determine, in advance their time to peak pH to best utilise the added buffering capacity this substance allows.

“…7 While muscle cell membranes are impervious to HCO 3 -, increasing extracellular HCO 3 -increases the pH gradient between intracellular and extracellular environments. 8 As a result, significantly higher blood lactate concentrations [BLa] have been observed following NaHCO 3 -supplementation, 9 suggesting NaHCO 3 -increases the efflux of H + and La -from working muscle into general circulation. As such, during specific exercise protocols (those involving a large anaerobic component), NaHCO 3 -may be efficacious in enhancing exercise performance.…”

“…The primary purpose of ergogenic aids is to reduce fatigue and increase power output. With high-intensity exercise, potential contributors to fatigue can be related to muscle energy production, a decline in muscle adenosine triphosphate (ATP), or impaired electrochemical events of muscle contraction/relaxation production (44). These decrements in performance can also be related to the accumulation of metabolites during exercise such as hydrogen ions resulting from increased lactic acid formation in high intensity exercise (44).…”

These decrements in performance can also be related to the accumulation of metabolites during exercise such as hydrogen ions resulting from increased lactic acid formation in high intensity exercise (44). Creatine monohydrate, and sodium bicarbonate, are two widely-studied ergogenic aids that have shown to attenuate the decline in fatigue while also increasing power output in high intensity exercise bouts such as sprinting (1,3,4,7,8,11,12,16,31,32,55,65,68).…”

The Effects of a Combined Supplementation of Creatine and Sodium Bicarbonate on Repeated Sprint Performance James Jeremy BarberThere is well-established research that suggests both creatine and sodium bicarbonate are effective ergogenic aids. However, only one published study has examined the combined effects of creatine and sodium bicarbonate. The primary purpose of this study was to determine if a combined supplementation of creatine monohydrate and sodium bicarbonate would further enhance the well-documented effects of creatine supplementation alone on repeated sprint performance. Thirteen healthy and fit males (Mean age = 21.15 ± 0.65 years and mean VO2 max = 66.72 ± 5.78) participated in this experimental study using a double-blinded crossover study design in which each subject was used as his own control. All subjects completed 3 conditions, followed by a 3-week washout period between each condition: 1) Placebo (Pl; 5 g maltodextrin + 0.5 g/kg maltodextrin), 2) Creatine (Cr; 5 g + 0.5 g/kg maltodextrin), and 3) Creatine plus sodium bicarbonate (Cr+Sb; 5g + 0.5 g/kg sodium bicarbonate). Each condition was a 2-day supplementation. In the morning after each supplementation, peak power, RPP, mean power, RMP, fatigue index, and perceptions of fatigue and GI distress were assessed during six 10-second repeated Wingate tests. Blood bicarbonate, pH, and lactate were measured 5 minutes before testing and immediately after the last Wingate sprint.The main findings were; 1) Cr+Sb produced 7% greater relative peak power and 4.6% greater peak power values than placebo, and 2) Cr+Sb demonstrated the greatest attenuation of decline in relative peak power over six repeated sprints. However, in contrast to our hypotheses, v no benefits from either supplementation were observed for relative mean power, fatigue index, and perception of fatigue. Considering that this current study found benefits from combining creatine and sodium bicarbonate, it suggests that combining the supplements may improve repeated sprint performance. Future research on a greater sample size, a specific athletic population, various exercise modes, and comparing results with a sodium bicarbonate alone supplementation would be beneficial in determining if this combined supplementation is worthwhile.vi
