NCT07650279

Brief Summary

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

Outcome Measures

Primary Outcomes (1)

  • Peak Oxygen consumption

    Peak oxygen consumption measured during the maximal cardiopulmonary exercise test (CPET) using a portable metabolic analyzer (Vo2 Master)

    during each maximal exercise test immediately after the breathing condition

Secondary Outcomes (4)

  • rating of perceived exertion (RPE)

    measured at baseline, during the exercise test and after recovery

  • Heart Rate Recovery

    difference between peak HR during CPET and HR at minute 1, minute 2 and minute 5 of recovery.

  • Time to completion of maximal exercise test

    during the exercise test

  • Peak Heart Rate

    measured during the maximal exercise test

Study Arms (2)

Coherence Breathing

EXPERIMENTAL

Participants complete 5 minutes of guided coherence breathing

Behavioral: Coherence Breathing

Spontaneous Breathing

ACTIVE COMPARATOR

Participants sit quietly for 5 minutes with spontaneous breathing

Behavioral: Spontaneous Breathing

Interventions

Participants complete 5 minutes of guided coherence breathing which consists or around 6 breathing cycles (5 seconds inhale and 5 seconds exhale)

Also known as: slow-paced breathing, resonance breathing
Coherence Breathing

Participants sit quietly for 5 minutes with their regular spontaneous breathing

Spontaneous Breathing

Eligibility Criteria

Age19 Years - 45 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Adults aged 19 to 45 years.
  • Any biological sex.
  • Recreationally active, defined as accumulating at least 3 hours per week of moderate-to-vigorous physical activity.
  • Able to perform maximal cardiopulmonary exercise testing on a treadmill.
  • Able to provide informed consent.
  • Cleared for moderate-to-vigorous physical activity based on the PAR-Q+ (or PAR-Q 2023).

You may not qualify if:

  • Accumulate less than 3 hours per week of moderate-to-vigorous physical activity.
  • Presence of a health condition that contraindicates maximal exercise testing, including:
  • Cardiovascular disease. Pulmonary disease. Metabolic disorders. Neuromuscular disorders. Orthopedic limitations that impair exercise performance.
  • Acute illness that would interfere with participation or exercise testing.
  • Inability or unwillingness to complete study procedures.
  • Inability or unwillingness to provide informed consent.
  • Not cleared for moderate-to-vigorous physical activity based on the PAR-Q+ (or PAR-Q+ 2023).
