Introduction: Pelvic floor dysfunctions prevalence in the female population is extremely high; one in every four woman has experienced moderate to severe symptoms of at least one pelvic floor disorder. Its etiology seems to have a strong correlation with the execution of forces, poor motor control and increased intra-abdominal pressure. Yoga is a physical, psychological and spiritual discipline originated in India over 2.000 years ago and currently it is being systematically practiced by more than 8.000.000 people around the world. One of the main characteristics is the body awareness development as well as control of the breathing. The pelvic floor awareness and activation (Mulabhanda) are basic elements in the practice of Hatha Yoga. An exercise routine focused on maintaining a low intra-abdominal pressure (Hypopressive Yoga / HY) would achieve an increase in the benefits that Yoga has over the pelvic floor.

Objective: To compare intra-abdominal pressure during the practice of conventional Hatha Yoga versus a Yoga practice incorporating hypopressive expiratory apneas (HY).

Methodology: The intra-abdominal pressure was measured in centimeters of water () in four healthy volunteers, by means of a balloon located in the vaginal posterior fornix using a Mediwatch Sensic Clinic™ Urodynamic equipment. Three Hatha Yoga postures were selected due to their parallelism with daily life activities: Tadasana or standing posture, Utkatasana or squat posture and Ardha Uttanasana or standing half forward bend posture. A set of precise instructions are given to execute this postures according to conventional Hatha Yoga and then a second set of instructions to execute Hypopressive Yoga postures. For the data analysis a non-parametric statistic was applied. Each Yoga posture was compared with their respective hypopressive homologous, implementing the Mann-Whitney rank-sum test in the software Stata™13.

Results: The volunteer’s characteristics are presented in Table 1. None of the volunteers had any significant medical-surgical history. The registered data is summarized in Table 2. The standing posture Tadasana shows a statistically significant difference between the conventional practice and the hypopressive alternative (). In the remaining postures, a considerable decrease in intra-abdominal pressure was also found; however, these differences did not reach statistical significance, probably due to the small sample size.

Conclusions: Intra-abdominal pressure decreases significantly during the practice of Hypopressive Yoga in relation to the practice of conventional Hatha Yoga. This could generate benefits both in the awareness and the pelvic floor control, among others.

New studies with greater statistical power are required to quantify the real benefits of the proposed practice.
