a Exposure-by-intensity interaction and b intensity-by-time interaction for PEFR. Significance is set at p < 0.05. For the exposure-by-intensity interaction data is collapsed across all time points and for the intensity-by-time interaction data is collapsed across both exposure conditions. * Low-intensity (p = 0.011) and rest (p = 0.017) are significantly less than high-intensity exercise at the post-exercise time point
