In this secondary analysis, there was no difference between morning (AM) and afternoon/early evening (PM) exercisers in blood glucose, insulin, body composition, or muscular strength following 12 wk of supervised exercise. However, examining within-group changes, glucose area under the curve (AUC) was significantly reduced in PM exercisers, but not in AM exercisers.
