  1. Columns two and three specify the exercise stimulus and ROI region for each measurement. The baseline, post-exercise, and ΔCrCEST Asym. %, as well as the τCr are shown in the last four columns. For each moderate/intense exercise protocol, CrCEST was measured in both calf regions whereas only one carnosine acquisition was taken in the most acidic portion of the calf as determined by the mild exercise.
