Data are means (±SD). Plasma insulin concentration at rest (Ins₀), after warm-up (Ins_w), at the end of Wingate test (Ins_end) and during recovery (Ins₁₀), young trained group (YT), young control group (YC), middle-aged trained group (AT), middle-aged control group (AC), before training (P1), after training (P2).

^aSignificant differences from before and after training, P < 0.05.

^bSignificant differences between AT and AC, P < 0.05.

^cSignificant differences between YT and YC, P < 0.05.

^dSignificant differences between YT and AT, P < 0.05.

^eSignificant differences between YC and AC, P < 0.05.
