FIGURE 4.

The effect of high- and moderate intensity exercises on markers of physiological and metabolic activity. Bicarbonate (A), creatinine (B), potassium (C), chloride (D), and sodium (E) at multiple timepoints shown in hours: at baseline (0), during (0.5), at the end of exercise (1) and post-exercise at different timepoints (1.5, 2, 3, 6, and 24). Serum levels are presented in mmol/L, except for creatinine which is shown in μmol/L. High intensity exercise included 1 h cycling at 70% W_max in hydrated (red lines) and dehydrated condition (blue lines) and intermittent cycling at 55/85% W_max in blocks of 2 min (purple lines). Moderate intensity exercise was represented by 1 h cycling at 50% W_max (green lines). The black lines show serum levels in the rest condition.
