Whatever your algorithm is calling them this week. The theory has been the same since 1984: you do the breath, you hold the posture, your intra-abdominal pressure drops, and your pelvic floor switches on because of that pressure drop.Nobody had measured the pressure.Silvia Saraiva did. She trained 36 women who had never done a hypopressive in their lives, gave them two weeks to practice, then brought them into the Motor Function Measurement lab at the University of Ottawa with an intra-abdominal pressure sensor, EMG inside and out, and ultrasound running. Supine and standing. With the hypopressive posture and without it.The pressure didn't drop. The pelvic floor did turn on. Just not through the mechanism we have all been teaching.Here's what makes this conversation worth your time: Silvia is hypopressives-trained. She still teaches them. She has patients who seek her out specifically to learn them. She is not here to tell you to stop. She is here to tell you the explanation doesn't hold up.🔹 What a hypopressive actually is, broken all the way down  🔹 The theory, and where it came from  🔹 Why the measurement tools matter more than most of us want to admit  🔹 What happened to intra-abdominal pressure lying down versus standing  🔹 How hard the pelvic floor actually worked, compared to a max contraction  🔹 Whether nailing the posture changed anything  🔹 If the pressure didn't drop, what IS causing the contraction  🔹 What Silvia tells the patients who ask her to teach them  🔹 Where hypopressives fit if strength is the goalSilvia Saraiva, BScPT, MScHK, is a pelvic health physiotherapist and researcher who completed her Master of Science in Human Kinetics at the University of Ottawa under Dr. Linda McLean. Her paper is out now in Physiotherapy, and there is a second one coming.When you learned hypopressives, or taught them, was the pressure drop the whole point? I want to know what you were told and what you think after listening to the pod!Saraiva S, McLean L.
