Key result
Cycling with intermittent pressure elicits normal HR and SBP but alters recovery MAP versus standard cycling.
Why the study?
The physiological responses to intermittent positive and negative pressure during stationary upright cycling needed evaluation.
Does stationary cycling with intermittent positive and negative pressure alter acute cardiovascular and physiological responses compared to standard cycle ergometry in healthy individuals?
Does stationary cycling with intermittent positive and negative pressure alter acute cardiovascular and physiological responses compared to standard cycle ergometry in healthy individuals?
Stationary cycling with intermittent positive and negative pressure elicits distinct mean arterial pressure recovery dynamics and a less pronounced heart rate increase compared to standard ergometry, while maintaining similar comfort levels.

IPNP cycling shows normal acute responses in healthy adults; leaves open clinical relevance of MAP recovery differences pending larger trials.
Background: This study evaluated the physiological responses to intermittent positive and negative pressure (IPNP) in 17 healthy, recreationally active individuals (10 males, average age 33.1 years, mean BMI 26.1 kg/m²) during stationary, upright cycling. Methods: We assessed acute IPNP effects on heart rate variability (HRV), blood pressure, and cardiovascular responses during moderate-intensity exercise. Participants engaged in two exercise modalities: Monark cycle ergometry (Mc) and cycling with IPNP, ranging from ±15 to ±25 Mbar. Results: Results indicated normal physiological responses in heart rate and systolic blood pressure (SBP) from rest to peak exercise in both modalities. A non-significant difference in SBP was observed during Mc compared to IPNP. Significant differences in mean arterial pressure were noted during recovery from IPNP cycling, highlighting a distinct cardiovascular response. HR increased in both conditions during exercise, with a more pronounced increase during Mc. Comfort and perceived exertion revealed no significant differences between the two modalities, indicating the potential acceptability of IPNP therapies. Conclusion: The study provides valuable insights into cardiovascular dynamics during stationary cycling with intermittent positive and negative pressure and highlights key physiological responses that warrant further investigation.

Vecchio et al. (2025) studied Healthy, recreationally active individuals (n=17). Cycling with intermittent positive and negative pressure (IPNP) vs. Monark cycle ergometry (Mc) was evaluated on Heart rate variability, blood pressure, and cardiovascular responses. Cycling with intermittent positive and negative pressure elicited normal heart rate and systolic blood pressure responses, with significant differences in mean arterial pressure during recovery.
