Biomarkers in Endurance Exercise: Individualized Regulation and Predictive Value

Figure 1

Data sampling and data analysis. (a) Time schedule of the experimental procedure. (b) z-standardization was performed for each biomarker before (c) k-means clustering and (d) regression were calculated. Predictions were based on two different models. A binary group model (model 1) or a bag of regression trees based on the prevalue (model 2).
