Interval training with active recovery significantly increased plasma adrenaline (2.82 vs. 1.03 nmol/l) and noradrenaline (7.22 vs. 6.65 nmol/l) responses to maximal exercise (p<0.05).

Does active recovery during interval training increase plasma catecholamine responses to maximal exercise compared to passive recovery in young men?
Interval training with active recovery induces greater physiological stress and catecholamine release in response to maximal exercise compared to passive recovery.
p-value: p=<0.05
The effect of recovery mode (Active AR vs. Passive PR) on plasma catecholamine (Adrenaline A and Noradrenaline NA) responses to maximal exercise (Exemax) was studied during interval training (IT). 24 male subjects (21.1±1.1 years) were randomly assigned to a control group (CG, n=6), AR training group (ARG, n=9) or PR group (PRG, n=9). ARG and PRG participated in an IT program 3 times a week for 7 weeks. Before and after training, maximal oxygen uptake (VO2max) and maximal aerobic velocity (MAV) were measured. Plasma A and NA were determined at rest, at the end of Exemax and after 10 and 30 min of recovery. Training induced significant changes only in ARG: an increase of VO2max and MAV along with a significant increase of A and NA at the end of Exemax (2.82±0.15 vs. 1.03±0.15 nmol/l and 7.22±0.36 vs. 6.65±0.57 nmol/l, respectively p0.05). The present results show that IT with AR induces a significant increase of A and NA concentrations in response to maximal exercise. The study furthermore shows that IT program with AR may induce more stress than the same program with PR.
Abderrahmane et al. (Tue,) conducted a rct in Healthy males undergoing interval training (n=24). Interval training with active recovery vs. Passive recovery and no training (control) was evaluated on Plasma adrenaline and noradrenaline responses to maximal exercise (p=<0.05). Interval training with active recovery significantly increased plasma adrenaline (2.82 vs. 1.03 nmol/l) and noradrenaline (7.22 vs. 6.65 nmol/l) responses to maximal exercise (p<0.05).
