| Abstract |
The aim of this study was to examine the effect of β-alanine supplementation on repeated sprint performance during an intermittent exercise protocol designed to replicate games play. Sixteen elite and twenty non-elite game players performed the Loughborough Intermittent Shuttle Test (LIST) on two separate occasions. Trials were separated by 4 weeks of supplementation with either β-alanine (BA) or maltodextrin (MD). There was no deterioration in sprint times from Set 1 to Set 6 of the LIST in either group prior to supplementation (elite: P=0.92; non-elite: P=0.12). Neither BA nor MD supplementation affected sprint times. Blood lactate concentrations were elevated during exercise in both groups, with no effect of supplementation. β-Alanine supplementation did not significantly improve sprint performance during the LIST. Neither group showed a performance decrement prior to supplementation, which might have masked any benefit from increased muscle buffering capacity due to β-alanine supplementation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 July 2012.
All research outputs
#14,180,146
of 24,712,008 outputs
Outputs from Amino Acids
#946
of 1,597 outputs
Outputs of similar age
#91,623
of 164,787 outputs
Outputs of similar age from Amino Acids
#16
of 27 outputs
Altmetric has tracked 24,712,008 research outputs across all sources so far. This one is in the 41st percentile – i.e., 41% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,597 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.5. This one is in the 40th percentile – i.e., 40% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 164,787 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 43rd percentile – i.e., 43% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one is in the 44th percentile – i.e., 44% of its contemporaries scored the same or lower than it.
