Primary Outcome Measures

Name	Time	Method
Cycling performance, measured in power. [Throughout the cycling performance test, peak power, mean power and total work will be measured. Specifically, these measures will be recorded throughout each of the six sets in the performance test.]

Secondary Outcome Measures

Name	Time	Method
Blood buffering capacity will be measured, via the analysis of capillary blood samples to determine blood pH and blood bicarbonate concentration.[Blood buffering capacity will be determined via the change between baseline and experimental trials.<br><br>Capillary blood samples will be taken during participants' second and third visits to the laboratory (baseline and experimental testing sessions). A capillary blood sample will be taken upon participants' arrival at the laboratory, as well as approximately 1 minute prior to the start of the performance test. Further capillary blood samples will also be taken immediately after completion of the six sets included in the cycling performance test. ];Blood 2,3-diphosphoglycerate and phosphate content will be determined via the analysis of venous blood samples.[Venous blood samples will be taken upon participants' arrival in the laboratory (for their second and third laboratory visits), and 1 minute after the completion of the cycling performance test.]
