Acute Exercise Intervention in Breast Cancer Survivors

NCT ID: NCT03779867

Last Updated: 2025-01-23

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: NA
• Total Enrollment: 112 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2019-03-25
• Study Completion Date: 2024-12-31

Brief Summary

This trial studies how a 45-minute bout of acute exercise in women with a history of breast cancer can affect factors associated with breast cancer and help doctors learn more about how exercise can help prevent breast cancer.

In an earlier part of the study, investigators looked at the effects of the same intervention in women without a history of cancer.

Detailed Description

OUTLINE: Participants are randomized to 1 of 2 arms.

ARM I: Participants undergo a moderate-intensity acute exercise bout over 45 minutes.

ARM II: Participants rest by sitting for 45 minutes.

EXTENSION: After completion of initial study recruitment and data collection, an extension was approved in 2023.

EXTENSION OUTLINE: Participants are randomized to 1 of 2 arms.

EXTENSION ARM I: Participants exercise on a stationary bike for 45 minutes.

EXTENSION ARM II: Participants rest by sitting for 45 minutes.
