Figure 3. Treadmill or wheel-running exercise during the inactive period increases the levels of serum corticosterone and peripheral tissue NE/MHPG.

Figure 3

(a) Experimental schedule. The white and black bars indicate environmental 12 h light and dark conditions. The orange short bar indicates forced exercise periods. The green short bar indicates voluntary exercise periods. The black arrow indicates the sampling time. (b) Serum corticosterone level after 3 days or 10 days of treadmill exercise or wheel-running exercise. (c) NE and MHPG levels in the kidney, liver and Sub gla after 3 days or 10 days of treadmill exercise or wheel-running exercise. All values are represented as mean ± SEM (No-Ex, n = 13; 3 days T-Ex, n = 4; 3 days W-Ex, n = 6; 10 days T-Ex, n = 5; 10 days W-Ex, n = 6). $$p < 0.01 $p < 0.05 versus No-Ex, evaluated using the Kruskal-Wallis test with Dunn post-hoc test. No exercise, treadmill exercise or wheel-running exercise: No-Ex, T-Ex, or W-Ex, respectively.
