About

The purpose of this research is to study the feasibility of a specific training program for the breathing muscles (inspiratory muscle training) and the effects on how breathing is regulated during exercise in childhood cancer survivors.

Full description

During the first study visit, participants will undergo a series of pulmonary function and muscle performance tests followed by treadmill walking trials at different speeds with concurrent expired gas analysis via a face mask. The participants will then perform a training program for the breathing muscles at home for 6 weeks. The research team will follow up each week via telehealth visits to support training. After the 6-week training program, participants will return in-person for a follow-up visit and will undergo the same series of assessments as the first visit.
