Effects of insulin and exercise on insulin-independent and insulin-dependent glucose uptake in single fibers from each fiber type. *P < 0.001, insulin vs. no insulin within the same fiber type in both the SED and the 3.5 h postexercise (3.5hPEX) groups; †P < 0.05, 3.5hPEX with insulin vs. SED with insulin within the same fiber type; ‡P < 0.01, 3.5hPEX no insulin vs. SED no insulin in the same fiber type.
