Monitoring Your Exercise-related Metrics Over Time Via Wearable Electronic Devices

May 18, 2026 updated by: M.D. Anderson Cancer Center
To test the use of a continuous activity and heart rate tracker (Fitbit) and continuous glucose monitor (CGM) in monitoring daily exercise-related activities.

Study Overview

Status

Active, not recruiting

Conditions

Detailed Description

Primary objective:

To evaluate the feasibility of a CGM-based physical activity intervention that includes the use of CGM and Fitbit®.

Secondary objectives:

To examine changes in physical activity motivation and other related psychosocial variables (e.g., intention, perceived benefits, outcome expectancy) before and after the intervention.

Exploratory objective:

Examine cancer-related biomarkers and their associations with daily glucose pattern.
