Beta-Alanine - PowerPoint Presentation

Slide1

Beta-Alanine

Beta-AlanineSlide2

Beta-alanine

Non-essential amino acidProduced naturally in the liver

Combines with the amino acid L-

histidine

in muscle cells to form Carnosine. Beta-alanine is the rate limiting factor in Carnosine productionCarnosine increases the body’s buffering ability to H+ during intense exercise

(Howe et al., 2013)Slide3

Beta-Alanine on Short Duration HIE

(Howe et al., 2013)Slide4

44% likely to increase average power output

Isokinetic average power/repetition significantly increasedFatigue index significantly reducedTime trial performance and short duration muscular force production benefits from beta alanine

Conclusions

Improved fatigue indexHIE intermittent performance improved

Training performance can be significantly improved over just 4weeks

Improved exercise capacity

Co-supplementation with sodium Bicarbonate shows slightly greater benefits that Beta-alanine alone(Howe et al., 2013; Hobson et al., 2013; Chung et al., 2012; Hobson et al., 2012; Saunders

et al.,

2012)Slide24

Type of Athlete that would benefit

Short HIE performersIntermittent HIE performers

Events lasting 60-240s optimally

Events over 240s still will have significant improvements compared to placebo however much less than the difference in 60-240s

Time trials such as 2,000m rowing, cycling or 1500m running ideal(Howe et al., 2013; Hobson et al., 2013; Chung et al., 2012; Hobson et al., 2012; Saunders et al., 2012)Slide25
