Glycemic Response to Exercise
Glycemic response to exercise shows how blood sugar shifts during sprints, endurance, and recovery. Fueling and session type shape the curve more than generic rules.
Glycemic response to exercise describes how blood glucose rises or falls during and after training—sprints may spike briefly, long zone 2 often lowers post-exercise glucose, and fasted work varies by individual. Fueling before hard sessions stabilizes performance.
CGM users should compare same-session types, not random days.
Common questions
-
Why does glucose spike during intense intervals?
Adrenaline and liver glucose release can raise readings temporarily during hard efforts. Post-session trends and next-day fasting glucose matter more for metabolic health.
