Effects of high intensity interval training on exercise capacity in people with cystic fibrosis: a randomised controlled trial
People living with CF not only have reduced exercise capacity but also have a high daily treatment burden involving medication, nutritional supplementation and airway clearance. For this reason it can be difficult to incorporate exercise into their daily routine.
The CF Research Unit, led by PhD candidate Abbey Sawyer, are undertaking a randomised controlled trial to investigate the effectiveness of a cycling-based, high intensity interval training (HIIT) program on exercise capacity in people with CF. The HIIT program comprises of 10 minutes of exercise completed three days per week for eight weeks.
The aim of this randomised controlled trial is to determine effects the program has on a person’s exercise capacity, health-related quality of life, exercise self-efficacy, feelings of anxiety, depression, enjoyment and muscle oxidative capacity.
The study will also report on:
- The proportion of participants who develop post-exercise quadriceps femoris muscle soreness each week during the 8-week HIIT program as well as the severity of this symptom;
- The participant tolerance of the 8-week supervised HIIT program;
- The cardiorespiratory and symptom responses elicited during the HIIT sessions throughout the 8-week program and;
- The behaviour change techniques employed throughout the program.
Recruitment began in 2017 and will be completed by mid-2019.
