Biomarkers in Endurance Exercise: Individualized Regulation and Predictive Value

Figure 3

Grouping results based on k-means clustering. Depicted are the median and the 25% quantile for the total group (left column) in grey and for both groups after clustering for day 1 (second column) and day 2 (third column) as well as VO₂max for the corresponding groups. (a) CK kinetics for the whole group and for the identified subgroups for both testing days, as well as the VO₂max for the subgroups. (b) Cortisol for the whole group and for the identified subgroups for both testing days, as well as the VO₂max for the subgroups. (c) IL-8 kinetics for the whole group and for the identified subgroups for both testing days, as well as the VO₂max for the subgroups. (d) IL-10 kinetics for the whole group and for the identified subgroups for both testing days, as well as the VO₂max for the subgroups.
