Glycogen At rest: FFAsDuring exercise: CHO Fats (when glycogen
sparing and when glycogen stores diminished)
Protein (last resort)Intensity of activity
Very High (>95% max HR) High (>85% max HR)Used for increase in intensity in long duration events
RestingSub max intensity (<80% max HR)
Duration system is dominant during activity
