Abstract
The efficacy of high intensity exercise for improving symptoms of chronic idiopathic constipation, a highly prevalent disorder of gut brain interaction (DGBI), remains uncertain. The aim of this case report was to investigate the feasibility, safety, and efficacy of 8-weeks of combined high-intensity interval training (C-HIIT) for a person (female, 23 years old) with chronic constipation.
The participant enrolled in the C-HIIT for DGBI controlled trial that aims to recruit 32 participants with DGBI. Following comprehensive assessments of gastrointestinal symptoms, neuromuscular fitness, cardiorespiratory fitness and mental health, the participant completed an 8-week intervention consisting of thrice weekly 26-minute C-HIIT sessions. These consisted of a 3-minute aerobic warm-up (treadmill; 50-60% peak heart rate [HRpeak]) followed by 4-minutes of high-intensity aerobic exercise at ≥85% HRpeak. After 1-minute rest, eight whole body resistance exercises were performed. These involved continuous repetitions with good technique for 1-minute at an ≥8/10 (very hard) rating of perceived exertion; 1-minute rest separated each exercise. Adverse events were recorded throughout the intervention.
The participant adhered to the intervention, attending 100% of sessions and reaching the prescribed intensity for 100% of aerobic and 80% of resistance exercises. Efficacy of the exercise training was indicated by a reduction in the severity of gastrointestinal symptoms measured via the irritable bowel syndrome-symptom severity scale (from 111 to 100) and the structured assessment of gastroIntestinal symptoms (39 to 12). There were some improvements in neuromuscular fitness (handgrip strength: 27 to 29.5 kg, 30-second sit to stands: 12 to 10 repetitions) and cardiorespiratory fitness (VO2max: 36.7 to 38.2 mL/kg/min). No changes were observed in mental health (Hospital Anxiety and Depression scale), and one non-serious adverse event (nausea post-eating), which was deemed not related to the intervention.
The C-HIIT intervention in a person with DGBI was feasible, efficacious and safe.
