  • Values are expressed as mean±SD.

  • BG90, BG105, BG120, BG150: BG level 90, 105, 120 and 150 min from the beginning of lunch.

  • ΔBG90–105: difference between BG90 and BG105.

  • Net ΔBG90–105: ΔBG90–105 for ST-EX or BI-EX minus ΔBG90–105 for REST.

  • * and ** indicate the presence of significant differences (p<0.05 and p<0.01, respectively) from IGT.

  • † and ‡ indicate the presence of significant differences (p<0.05 and p<0.01, respectively) from REST.

  • § and  ¶ indicate the presence of significant differences (p<0.05 and p<0.01, respectively) from BI-EX.

  • BG, blood glucose; BI-EX, bicycle exercise; IGT, impaired glucose tolerance; ST-EX, stair climbing–descending exercise.
