What is the valsalva maneuver?

The Valsalva maneuver is a specific physiological technique that involves forced exhalation against a closed glottis. This maneuver occurs when an individual tries to exhale while keeping the mouth and nose closed, which leads to increased pressure in the chest and abdominal cavities. It is often used during activities like heavy lifting or when trying to stabilize the core, as it can aid in maintaining intra-abdominal pressure and support the spine during strenuous activities.

The controlled closure of the glottis has implications for cardiovascular function, including changes in heart rate and blood pressure. This is a critical aspect of the maneuver, as it highlights the balance of pressure within the thoracic cavity and its systemic effects.

Understanding the Valsalva maneuver's function and technique is important for trainers, as it helps in teaching safe lifting techniques and managing intra-abdominal pressure during exercise.
