The effects of sodium bicarbonate ingestion on maximal tethered treadmill running
Date of this Version
Aim: This work aimed to investigate the effects of bicarbonate buffering on repeated tethered treadmill sprinting. Eight males with the following physical characteristics (Mean±SD: Age,25.1±4.2 yr; height 177.5±7.1 cm; body weight 73.3±8.9 kg) undertook all testing over the period of seven days.
Methods: Each subject undertook two test sessions (Placebo - P and Experimental - E) on a non-motorised treadmill. Subjects sprinted for 30 s followed by 180 s of passive recovery and repeated three times. The P trial was 0.045 g NaCl take in 500 ml flavoured water over the period of 60 min, while the E trial consisted of 0.3 g NaHCO3·kg-1 body weight taken in the same manner. Blood samples were taken pre ingestion, pre exercise, and at the end of each minute after each sprint session.
Results: The total distance travelled in the bicarbonate group over the 90 s of activity were significantly (P
Conclusion: The use of sodium bicarbonate significantly increased tethered treadmill running most likely by buffering hydrogen ions produced through anaerobic glycolysis.
