Cystic Fibrosis Heart Rate and Exercise Study

Simplifying Prognostic Testing in Cystic Fibrosis: Correlation of Heart Rate Recovery After Sub-maximal Aerobic Exercise with Maximal Exercise Testing Results

 

Protocol Description

This study compares two testing regimens for cystic fibrosis patients to determine whether a shorter, easier exercise test called STEP-30, can be as effective as the traditional maximal exercise test. By determining the point at which the heart and lungs become physically stressed during exercise, maximal exercise tests are often used to help to predict how healthy patients with cystic fibrosis will be in the future. People with cystic fibrosis who perform well on maximal exercise tests tend to be less sick in the years after the test than people who do not perform as well.

Eligibility Criteria

Children and young adults of both genders who have already been scheduled for the maximal exercise test are eligible to participate in this study.
Males and Females: Age 8 and older

Requirements
Prior to engaging in the maximal exercise test, participants will do the STEP-30 exercise. The STEP-30 exercise requires that the child step on and off a stair 30 times a minute for 3 minutes. Heart rate and oxygen saturation are monitored before during and after the test.
Visits: 1
Duration: Not applicable

Status: Open for Enrollment
