But in types like karate or judo, it could possibly get so loud you may’t hear your self suppose. Between foot stomps, sharp exhales, and battle cries just like the kiai, it’s a full-on sonic expertise. You would possibly marvel, is there an actual objective behind all that noise, or is it only for present?
Jason Sawyer, Associate Professor and Exercise and Movement Science Program Coordinator at Bryant University, says there’s actual science behind all that shouting.

What is Kiai Breathing?
“A kiai—also referred to as a kiap or grunt—is a vocalization produced during explosive physical movements,” Sawyer says. “This technique involves a forceful contraction of the abdominal muscles while exhaling through an open mouth. Martial artists commonly employ the kiai, believing it enhances muscular power and performance.”
How It Works
Research reveals that vocalizations just like the kiai can truly increase muscular energy. By forcefully exhaling from the diaphragm, you activate the core and ramp up neural firing alongside the spinal wire, serving to you strike with extra energy.
“Recent findings further support this, showing that performing a kiai during the execution of punches and kicks resulted in over a 10% increase in force output compared to breath-holding. Moreover, vertical jump height is increased by approximately 4% when using a kiai.”
Utilizing Kiai Breathing in Your Day-to-Day Life
Kiai is not only for martial artists both. While it may not fly at your desk throughout the workday, the method is usually a highly effective instrument within the fitness center, particularly throughout explosive actions, serving to to increase focus, rigidity, and general efficiency.
“This technique may be beneficial when applied to activities such as jumps, Olympic weightlifting, throws, or during the final repetitions of a challenging set, where maximal effort is required,” Sawyer provides.

Benefits of Kiai Breathing
Aside from the doable bodily advantages, Sawyer says that people who incorporate a kiai into their training typically report enhanced psychological focus and heightened focus.
“This vocal expression not only serves as a physical release of energy but also stimulates the nervous system, increasing nerve activity and alertness,” he provides. “As a result, practitioners may experience improved mental clarity and sharper cognitive function, which can contribute to a more effective and engaging workout. By synchronizing breath, voice, and movement, the kiai acts as a powerful tool to elevate overall performance.”
