Do More, B'More, Live Fit

Status Completed

Clinical Trial Summary

Physical activity (PA) in individuals with cystic fibrosis (CF) improves exercise capacity, slows decline in lung function, increases mucus clearance and improves health-related quality of life (HRQoL). Establishing and maintaining an exercise routine remains challenging and programs promoting PA in people with CF have poor participation. Moreover, while the positive effects of physical conditioning on lung function have been well reported, conventional measurements of lung function may lack the sensitivity to reveal improvement in mild lung disease.

This randomized control trial (RCT; N = 60) evaluates the Do More, B'More, Live Fit, a 6-month fitness program designed to optimize exercise habits of 12-21 year-olds with CF through structured exercises with personalized coaching, exercise equipment including the FitBit Flex, online support and motivational messages delivered electronically. The intervention incorporates fitness preferences and encompasses endurance, strength and flexibility exercises while adjusting to physical fitness needs. The hypothesis is that intervention participants will have increased and sustained engagement and better health outcomes compared to control group participants. The investigators' specific aims are to:

1. Increase daily PA and measures of fitness

2. Improve lung clearance index (LCI) and participant HRQoL

3. Demonstrate feasibility, accessibility and satisfaction of intervention using semi-structured interviews

The results of this pilot evaluation of the Do More, B'More, Live Fit program will offer novel insight into factors that sustain engagement in exercise programs and identify if LCI is an appropriate clinical outcome to assess PA interventions. Results will inform future RCT of interventions to optimize exercise habits of adolescents with CF.
