Key result
Lower body positive pressure at 75 mmHg during exercise increased mean arterial blood pressure more in the supine (40 +/- 3 mmHg) than upright (25 +/- 3 mmHg) position.
Why the study?
Does lower body positive pressure alter cardiovascular responses depending on posture and exercise state in human subjects?
Population

Posture modulates hemodynamic responses to lower body positive pressure; leaves open relevance for clinical populations or device use.
Does lower body positive pressure alter cardiovascular responses depending on posture and exercise state in human subjects?
The systemic pressure response to lower body positive pressure is dependent on body position, with larger pressure responses associated with the supine position both at rest and during dynamic leg exercise.
Nishiyasu et al. (1998) studied this question. Lower body positive pressure (LBPP) vs. Without LBPP was evaluated on Mean arterial blood pressure (MAP). Lower body positive pressure at 75 mmHg during exercise increased mean arterial blood pressure more in the supine (40 +/- 3 mmHg) than upright (25 +/- 3 mmHg) position.
