Official title
The Effects of Four-week Breathing Interventions on Gastrointestinal Symptoms, Heart Rate Variability, and Psychological Measures in Runners
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Recent research has suggested that stress and anxiety levels are associated with gastrointestinal (GI) symptoms in endurance athletes (runners, cyclists, triathletes). Yet, there has been limited attempt to evaluate whether GI symptoms during running can be mitigated by interventions designed to reduce stress and anxiety. Thus, this study will evaluate the effects of four-week slow deep breathing and mindful breath counting interventions on subjective and objective measures of stress/anxiety and GI symptoms in runners with mild-to-high anxiety and that are prone to GI symptoms during runs.
