Suggested initial pre-exercise meal insulin bolus reduction for activity started within 90 min after insulin administration

Exercise intensity	Exercise duration
	30 min	60 min
Mild aerobic (∼25% VO2max)	−25%*	−50%
Moderate aerobic (∼50% VO2max)	−50%	−75%
Heavy aerobic (70%−75% VO2max)	−75%	N-A
Intense aerobic/anaerobic (>80% VO2max)	No reduction recommended	N-A

Recommendations compiled based on four studies (94–97). N-A, not assessed as exercise intensity is too high to sustain for 60 min.
