What’s This Research About?
Most yogic breathing techniques aim to help with anxiety, tension, and relaxation. But breathing techniques can also boost athletic performance by increasing power output, strength, and even tolerance to extreme temperatures, the latter purported by the teachings of Wim Hof.
Several researchers have found increased power and strength using specialized breathing techniques such as a forceful exhalation, shouting, pranayama, or types of grunting used by Kiap in martial arts. One study found speed, power and aerobic capacity increased in a group of men following twelve weeks of pranayama breath training.
This research tested the effects of three yogic breathing techniques (Ujjayi, Bhastrika and Kapalabhati) on power output and compared the results to a control of normal breathing. Power output was analyzed while participants performed isokinetic leg extensions (extending the leg at a consistent speed) and pneumatic leg presses.
Hypothesis: Specific pranayama techniques would improve performance compared to normal breathing whether done before or during the test.
