What does the Valsalva maneuver involve?

The Valsalva maneuver involves breath holding to increase pressure within the chest and abdominal cavities. This technique is typically performed by taking a deep breath and then exhaling forcefully with a closed mouth and pinched nose, which creates increased intrathoracic pressure. This maneuver is often utilized during activities that require heavy lifting or straining, as it can help stabilize the core and improve performance by providing greater support to the spine.

The increased pressure also has physiological effects, impacting heart rate and blood flow, which can be beneficial during high-intensity exercise. While controlled breathing is important during exercise, and there are situations where breath control may be significant, the specific action of the Valsalva maneuver is distinct in its focus on breath-holding for pressure increase.
