Data are means (±SD). Plasma noradrenaline concentration at rest (NA₀), at the end of the warm-up (NA_w) at the end of the Wingate-test (NA_end) and after 10 min recovery (NA₁₀), 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.
