Summary of the acute exercise effect on fiber type-specific-stimulated glucose uptake, pAkt, and pAS160 at 3hPEX in HFD rat epitochlearis muscle

	Glucose Uptake	pAktSer473	pAktThr308	pAS160Ser704	pAS160Thr642	pAS160Ser588
Type I fibers	↔	↔	↔	↔	↓	Insufficient Signal
Type IIA fibers	↑	↔	↔	↔	↑	↑
Type IIX fibers	↑	↔	↔	↔	↔	↔
Type IIBX fibers	↑	↔	↔	↑	↑	↔
Type IIB fibers	↑	↔	↔	↑	↔	↔

↑, ↓, and ↔ indicate that the insulin-stimulated value at 3 h postexercise (3hPEX) was significantly greater, significantly less, or unchanged compared with the insulin-stimulated value in the sedentary condition for the same fiber type, respectively. Reported changes in the fiber-type specific glucose uptake values are from our previously published article (43). HFD, high-fat diet.
