Background: The dawn phenomenon (DP), characterized by abnormal early-morning glucose fluctuations, poses a serious risk to individuals with T2D.
Methods: The 110 recruited individuals were randomized into three exercise groups and a control group. Each mini-cycle of 5 days was separated by 1 day (G1), 2 days (G2), 3 days (G3), and a control group (GC), respectively. Nine mini-cycles of intervention per exercise group.
Results: The final sample size was 85. Compared with baseline and GC, all three groups showed a decrease (P < 0.01). Differences between groups were also observed (P < 0.01). DP improved in cycles 7, 8, and 9. G1 exhibited the greatest change in cycle 3, peaking earlier and higher than G2 and G3. From T4 to T9, G1 showed a decreasing trend.
Conclusions: Periodic exercise effectively attenuates DP in T2D, with shorter intervals yielding earlier and greater glycemic improvements.
