Table 1.
Summary of biospecimen collection conditions from the various investigations.
Fig 1.
Comparison of the relative (percentage) abundances of amino acids in (a) post-exercise sweat, (b) a water-washing taken after 12 hours rest following a post-exercise shower and (c) a water-washing taken immediately after showering and drying. Values are averages from three separate sampling events from one male participant.
Fig 2.
Total amino acid levels (μM) in sweat measured for two athletes completing a 40 minute self-paced cycle under controlled conditions compared against fasted plasma levels previously recorded for each of the athletes over a 6 week period.
Table 2.
Comparison of sweat amino acid concentrations with pre- and post-exercise plasma amino acid levels measured in the primary group of male athletes.
Fig 3.
The scatterplot of the principle component analysis (PCA) scores (factor 1 vs factor 2) of the amino acid composition profiles in sweat from the combined study cohort (n = 19).
The scores for each of the participants have been coded for membership of one of the three clusters: L = low, I = intermediate, H = high.
Table 3.
Comparison of amino acid concentrations in sweat from the “Low”, “Intermediate” and “High” SFLAA clusters compared with the post-exercise composition of plasma.
Fig 4.
The relative abundances of amino acids in blood plasma ranked from the most abundant to least abundant components compared with those observed in sweat from the “Low”, “Intermediate” and “High” SFLAA clusters.
