Summary

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.

Conditions

  • Childhood Cancer
  • Cancer Survivors

Interventions

DEVICE

POWERbreathe Plus IMT

Inspiratory muscle training will be performed using the POWERbreathe Plus IMT (POWERbreathe International Ltd., Warwickshire, UK), a commercially available inspiratory pressure threshold device. In this type of training, airflow is occluded until the generated inspiratory pressure reaches the predetermined threshold, which can be set at increments of 8 cm H2O. During the first week of training, the target intensity will be set at 50% of baseline maximal inspiratory pressure (MIP.) During the second week, the target intensity will be set at 60% of baseline MIP. Beginning at the third week and for the remainder of the training program, the target intensity will be set at 75% of the participant's baseline MIP. The target volume will be 5 sets of 6 breaths per day (total of 30 breaths per day), separated by 1-minute rest breaks between sets. The frequency of training will be 5 days per week, for a duration of 6 weeks.
