| description | We aimed to investigate haemodynamics during active and passive recovery following repeated bouts of supramaximal exercise.
Seven male athletes underwent two sessions of supramaximal exercise which consisted of a warm-up and of five bouts of cycling
at the maximum speed possible for 30 s against a resistance equivalent to 150% of the maximum workload achieved in a previous
incremental test. Bouts were separated by 1 min of recovery and followed by 10 min of recovery which was either active (pedalling
at 40 W) or passive (completely rest seated on the cycle). Haemodynamic variables were evaluated by means of impedance cardiography.
Heart rate (HR), stroke volume (SV), cardiac output (CO), mean blood pressure (MBP), thoracic electrical impedance ( Z 0 ) as an inverse index of central blood volume, and systemic vascular resistance (SVR) were assessed. The main findings were
that active recovery, with respect to passive recovery, induced higher changes from baseline in HR (+29.1 ± 4.5 versus
+15.6 ± 2.9 beats min â1 at the 10th minute of recovery, P < 0.05), SV (+19.9 ± 5.6 versus
â6.4 ± 3.3 ml, P < 0.01) and CO (+3.8 ± 1.2 versus
+0.4 ± 0.2 l min â1 , P < 0.01). Furthermore, MBP was similar between the two kinds of recovery despite an increase in Z 0 during passive compared to active recovery. These results suggest that the faster haemodynamic recovery towards baseline
and the decrease in cardiac preload during passive recovery may be successfully prevented by cardiovascular regulatory mechanisms
which include an increase in SVR, thus avoiding a drop in blood pressure. |
