Plasma norepinephrine in 18 males prior to and following rest, low-intensity cycling and high-intensity cycling. Significance is set at p < 0.05. For the intensity-by-time interaction data is collapsed across both exposure conditions. * Significantly less than post in the corresponding exercise intensity (high-intensity only). ** Significantly less than 1 h in the corresponding exercise intensity (high-intensity only). β Significantly greater in high-intensity compared to low-intensity and rest. Φ Significantly less than 1 h in the corresponding exercise intensity (low-intensity only)
