About this study
Official title: Yoga Outcomes Get Assessed in Cystic Fibrosis
The goal of this clinical trial is to investigate the effects of yoga participation for adults with cystic fibrosis.
The main question it aims to answer is: does participation in yoga affect health-related quality of life for adults with cystic fibrosis?
Researchers will compare a group completing a 12-week yoga programme alongside usual cystic fibrosis care, to a group completing usual care alone to see if the addition of yoga effects health-related quality of life.

What is being measured
The primary outcome is the main question the study is designed to answer.
Respiratory Health- related quality of life - measured by the respiratory domain of the Cystic Fibrosis Questionnaire - Revised.
Cystic Fibrosis Questionnaire - Revised (CFQ-R) respiratory domain.Scores range from 0 to 100, with higher scores indicating better health.
Measured: Baseline, 12 and 24-weeks
Secondary outcomes (4)
Other Health-related quality of life domains - captured on the Cystic Fibrosis Questionnaire - Revised (CFQ-R)
Cystic Fibrosis Questionnaire - Revised (CFQ-R) other eleven domains. Scores range from 0 to 100, with higher scores indicating better health.
Measured: Baseline, 12 and 24-weeks
One Minute Sit to Stand Test
Participant stands up and sits down from a chair for one minute and the number of completed sit-to-stands is recorded.
Measured: Baseline, 12 and 24-weeks
Forced Expiratory Volume in 1 second
Forced expiratory volume in 1 second (FEV1) obtained through spirometry. Measured in litres and percentage predicted (using Global Lung Index equations)
Measured: Baseline, 12 and 24-weeks
Forced vital capacity (FVC)
Forced vital capacity obtained through spirometry. Measured in litres and percentage predicted (using Global Lung Index equations)
Measured: Baseline, 12 and 24-weeks
