Metabolic Response to Exercise: Glucose, Ketones, and Lactate Changes #1265499 (License: Personal Use)

This bar chart displays pre- and post-exercise concentrations of glucose (mg/dL), beta-hydroxybutyrate (B-OHB, mM), and lactate (mM) across three exercise types: swimming, cycling, and high-intensity training. Swimming induces the greatest lactate increase (+279%) and moderate glucose rise (+37%), whereas high-intensity exercise elevates glucose most (+71%) but reduces B-OHB (-37%). Cycling uniquely lowers glucose (-16%) while sharply increasing B-OHB (+238%).

Used in sports science, nutrition, or clinical endocrinology articles to illustrate acute metabolic adaptations to different exercise intensities; targets fitness professionals, researchers, and patients managing metabolic health.
