Acute exercise-induced catecholaminergic responses after 16 weeks of community-based exercise training in early-stage breast cancer survivors

Figure 1 The acute exercise-induced response of epinephrine before and after completing a 16-week community-based exercise training program. A: Before training (PRE) responses were assessed using a group (BCS vs CON) × time [baseline (BASE), 0 hour, 1 hour] linear mixed model approach; B: After training (POST) assessments were assessed using a group (BCS vs CON) × training (PRE vs POST) linear mixed model approach; C: Confirmation of training-induced epinephrine (EPI) responses were pursued using an unplanned post hoc area under the curve analysis of EPI at PRE and POST. Data are mean (SD) with post-hoc comparisons performed using Tukey’s HSD test. ^aP < 0.001 effect of time (0 hour vs BASE); ^bP < 0.05 effect of phase (POST vs PRE). BASE: Baseline; 0H: Immediately post-exercise; 1H: 1-hour post-exercise; BCS: Breast cancer survivor; CON: Non-cancer control.

Figure 2 The acute exercise-induced response of norepinephrine before and after completing a 16-week community-based exercise training program. A: Before training (PRE) responses were assessed using a group (BCS vs CON) × time (BASE, 0 hour, 1 hour) linear mixed model approach; B: After training (POST) assessments were assessed using a group (BCS vs CON) × training (PRE vs POST) linear mixed model approach; C: Confirmation of training-induced norepinephrine (NE) responses were pursued using an unplanned post hoc area under the curve analysis of NE at PRE and POST. Data are mean (SD) with post-hoc comparisons performed using Tukey’s HSD test. ^aP < 0.001 effect of time (0 hour vs BASE). BASE: Baseline; 0H: Immediately post-exercise; 1H: 1-hour post-exercise; BCS: Breast cancer survivor; CON: Non-cancer control.
