About
The purpose of this study is to identify which supplemental intervention components added to an online exercise program contribute to the greatest increases in physical activity (total MVPA and percent meeting guidelines [≥150 min/week of MVPA]) in adults with knee replacement at 6 and 12 months. Secondary outcomes will examine changes in pain and physical function.
Full description
All participants will receive a 6-month, fully automated online behavioral exercise program (Energize! Exercise Program). This program is designed to increase moderate-intensity physical activity among individuals who engage in little to no physical activity at baseline. Over the course of the program, participants are given a physical activity goal which starts at 75 minutes per week and gradually progresses to 200 minutes per week. Participants are instructed to view a 10-15-minute video lesson weekly, during months 1-3, and monthly during months 4-6. These lessons teach behavioral principles for increasing exercise and maintaining physical activity long-term. Participants are also asked to complete an 'Apply Your Knowledge' activity after watching each video lesson. These activities are designed to help the participant engage more with the lesson content, with a particular emphasis on applying the content to their lives. Within this program, participants are also asked to plan and report their exercise each week, and automated feedback is provided based upon their weekly physical activity reports.
In addition to receiving the Energize! Exercise Program, participants will be randomly assigned to receive 0-4 supplemental intervention components (phone coaching, progress reports to providers, 'Hear From Others' videos, and individualized feedback) which are each described in more detail below.
