Study Summary

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.

Primary Outcome

Percentage of training runs that runners experience at least 1 gastrointestinal symptom (\>2 on 0-10 scale).

Interventions

  • BEHAVIORAL Slow deep breathing plus breath counting
  • BEHAVIORAL Normal-paced breathing plus breath counting
