Effects of habituation on the locomotor response during an incremental exercise test. (a) Timeline of the experiments and picture of an adolescent rat running in the forced wheel during the dark period. (b) Speed variation (y-axis) along time (x-axis) during the incremental exercise test. (c) Average of the total running time spent during the incremental exercise test comparing non-habituated (gray bar) and habituated (blue bar) rats injected with vehicle (NaCl, 0.9%, i.p.). Data: non-habituated: 16.65 ± 1.11 min (n = 5), and habituated: 36.75 ± 2.52 min (n = 14). t₁₇ = 4.6, *p < 0.001, unpaired t test. Diamonds represent individual values
