Implication

PCE may elevate acute cardiovascular load; leaves open its safety and utility in clinical populations.

Key Points

To evaluate cardiovascular and cardiac autonomic responses during rest and passive cycle exercise in trained versus untrained individuals.
Assessed cardiovascular parameters in trained males (N = 20) and fit, untrained male controls (N = 10) during rest and 6-minute passive cycle exercise (PCE) bouts at 30 and 60 rpm.
Measured heart rate (HR), stroke volume (SV), cardiac output (CO), total peripheral resistance (TPR), and mean arterial pressure (MAP).
Evaluated vagal cardiac modulation via time-series heart period variability (HPVts) and verified lack of muscle activation using electromyography (EMG).
No significant differences in cardiovascular responses occurred between trained and untrained groups during PCE, leading to combined group analysis.
Combined participants showed statistically significant increases in HR, CO, and MAP alongside a significant decrease in vagal tone measured by HPVts during light and medium PCE (P < 0.001).
Stroke volume responses were minimal and uniform across groups, indicating ineffective muscle pump function during passive cycling.

Structured PICO

Does passive cycle exercise alter cardiovascular response in trained and untrained males compared to rest?

Population

30 males (20 trained, 10 fit but untrained controls)

Intervention

Passive cycle exercise (PCE) for 6 min at intensities of 30 and 60 rpm

Comparator

Rest

Outcome

Cardiovascular response including heart rate (HR), stroke volume (SV), cardiac output (CO), total peripheral resistance (TPR), mean arterial pressure (MAP), and heart period variability (HPVts)surrogate

Passive cycle exercise significantly increases heart rate, cardiac output, and mean arterial pressure while decreasing vagal influence, likely due to mechanoreceptor stimulation rather than muscle pump effectiveness.
