Influence of different experimental recreation treatments on sympathoadrenergic and metabolic regulation mechanisms in repeated exercises.
The influence of different recreation treatments on the sympathoadrenergic regulation, heart rate, mean blood pressure, plasma lactate, and glucose levels was investigated in a study in which the 1000 m distance was performed twice by top middle- and long-distance runners. Between the two runs, executed three times in an interval of 1 week, different regeneration strategies such as active or passive recreation as well as progressive muscle relaxation (PMR) with cognitive skill (Cl) were applied. The best running times in the second run were achieved after the PMR with Cl. After this treatment heart rate (HR) and mean arterial blood pressure (MBP) were not higher than in the other forms of regeneration, although the norepinephrine (NE) and epinephrine (EPI) increase was significantly higher after the second run compared with other treatments. The lactate and glucose levels in plasma were significantly higher after PMR with Cl than after active and passive regeneration. After the recovery period both metabolites decreased faster after PMR with Cl. The percentage of catecholamine sulfates of the total amount decreased after the first and the second run without significant differences between the three recreation treatments.
