What does the Valsalva Maneuver involve?

The Valsalva Maneuver involves a forceful expiration against a closed airway. This technique occurs when a person attempts to exhale with the mouth closed and the nostrils pinched shut, creating increased intrathoracic pressure. This forceful action can be used in various situations, such as during heavy lifting or while trying to equalize ear pressure.

The maneuver can have physiological effects, such as temporarily increasing blood pressure and affecting heart rate due to the change in thoracic pressure. It is often taught in contexts like weightlifting or certain medical procedures where controlling pressure and stabilizing the core is essential. Understanding this maneuver is important in fitness and health settings due to its implications for safety and performance.
