Effects of Sodium Phosphate Supplementation on Maximal Oxygen Consumption and Blood Lactate

The Influence of Sodium Phosphate Supplementation on VO2max, Serum 2,3-diphosphoglycerate Level and Heart Rate in Off-road Cyclists

“…In a recent experiment with sodium phosphate salts Brennan et al (2001) showed a significant relationship between the blood serum concentration of phosphates and phosphate content in the erythrocyte (r=0,51; p=0,009), as well as between erythrocyte concentration of phosphates and the level of 2, 69;p<0,001). No significant relationships were detected between the blood serum phosphate concentration and the erythrocyte level of 2,3-DPG.…”

“…Brennan et al (2001) supplemented a group of cyclists (n=12) (VO2max = 60,6 ± 4,4 ml/kg/min) with sodium diphosphate (4g/d) over 4 days and reached no significant changes in the above considered variables. An additional factor that may regulate the erythrocyte concentration of 2,3-DPG includes the concentration of serum inorganic phosphates (P).…”

“…The literature provides both types of data, supporting and not supporting the ergogenic benefits of these supplements. (Cade et al 1984, Kreider 1992, Tremblay et al 1996, Brennan et al 2001.…”

Effects of sodium phosphate and beetroot juice supplementation on repeated-sprint ability in females

“…Furthermore, best sprints were 0.13-0.23 and 0.15-0.20 s faster (~6 % improvement; p < 0.01) after SP compared with placebo and BJ, respectively, for all sets (d = −0.54 to −0.89). While some studies have found no benefit of SP on exercise performance (Brennan and Connolly 2001;Buck et al 2014;Brewer et al 2014;West et al 2012), others have reported improved endurance exercise performance (Folland et al 2008;Kreider et al 1992) and aerobic capacity of 3.5-12 % (Brewer et al 2013;Cade et al 1984;Czuba et al 2008Czuba et al , 2009Kreider et al 1990Kreider et al , 1992Stewart et al 1990) following 3.6-4 g or 50 mg kg −1 of fat free mass (FFM) of SP ingested each day over a 3-to 6-day loading period. Furthermore, Brewer et al (2014) recently reported improved sprinting and time-trial efforts whilst cycling following SP loading.…”

The Effect of 6 Days of Sodium Phosphate Supplementation on Appetite, Energy Intake, and Aerobic Capacity in Trained Men and Women

“…Ergogenic benefits after such supplementation protocols include increased maximal aerobic capacity (VO 2max ; Cade et al, 1984;Czuba, Zajac, Poprzecki, Cholewa, & Woska, 2009;Kreider, Miller, Williams, Somma, & Nasser, 1990;Stewart, McNaughton, Davies, & Tristram, 1990), increased anaerobic threshold (Cade et al, 1984;Kreider et al, 1992), and improved cycling time-trial performance (Folland, Stern, & Brickley, 2008;Kreider et al, 1992). However, it is important to note that not all studies have observed ergogenic benefits after sodium phosphate supplementation (Ahlberg et al, 1986;Brennan & Connolly, 2001).…”
