Phase 2 Trial of Adaptive Versus Standard Dosing of Aerobic Training in Patients Receiving Chemotherapy for Primary Breast Cance

Summary

In this study, investigators will compare standard Aerobic Training/AT with adaptive Aerobic Training/AT. Standard AT will be a fixed (unchanging) amount of walking each week, while adaptive AT will adjust the level of exercise depending on participants' response to the exercise. Investigators will see how both study approaches (standard AT and adaptive AT) affect participants' CRF.

Interventions

• Behavioral
  Adaptive Aerobic Training/AT Dosing

  o In Phase A (\~32 weeks), AT will consist of supervised walking delivered up to 7 days per week using an adaptive dosing schedule that starts at 90 min/wk and is escalated 30 min/wk every 2 weeks to a maximal dose of 300 mins/wk. In Phase B (\~20 weeks), AT will consist of supervised adaptive AT dosing in patients with a CRF Δ\<3.50 ml O2 .kg-1.min-1 from baseline to \~32 weeks, or unsupervised AT in patients with a CRF Δ\>3.50 ml O2 .kg-1.min-1 from baseline to \~32 weeks. Supervised AT will be monitored using TeleEx.

• Behavioral
  Standard (fixed) Aerobic Training/AT dosing

  In Phase A (\~32 weeks), AT will consist of supervised walking delivered up to 7 days per week to achieve a cumulative total duration of: 90 min/wk (standard fixed dosing). In Phase B (\~20 weeks), AT will consist of supervised adaptive AT dosing in patients with a CRF Δ\<3.50 ml O2 .kg-1.min-1 from baseline to \~32 weeks, or unsupervised AT in patients with a CRF Δ\>3.50 ml O2 .kg-1.min-1 from baseline to \~32 weeks. Supervised AT will be monitored using TeleEx.
