Coherence Breathing Before Cardiopulmonary Exercise Testing
This randomized crossover trial will examine the acute effects of pre-exercise coherence breathing on cardiopulmonary exercise responses in recreationally active adults. Participants will complete two experimental conditions in randomized order: 5 minutes of guided coherence breathing and 5 minutes of quiet seated spontaneous breathing. Following each condition, participants will perform a standardized treadmill warm-up and a maximal cardiopulmonary exercise test. Outcomes will include oxygen consumption, heart rate, heart rate recovery, perceived exertion, time to completion, and heart rate variability. The findings may help determine whether coherence breathing can serve as an effective autonomic priming strategy before a bout of maximal exercise
