What is the Valsalva maneuver?

The Valsalva maneuver refers specifically to the act of exhaling forcibly with the glottis closed. This process occurs when an individual attempts to exhale but keeps their mouth and nostrils closed, which increases intrathoracic pressure. This is often used during heavy lifting or straining to help stabilize the spine and maintain core pressure, but it can also affect cardiovascular function by temporarily decreasing blood flow to the heart and brain.

Understanding this maneuver is essential for fitness professionals, as it can influence both performance and safety during exercises. For example, while it can aid in lifting heavy weights, improper use can lead to complications, especially in individuals with certain health issues. Recognizing the mechanics behind the Valsalva maneuver is important for teaching clients safe techniques during their workouts.
