Brief summary

The purpose of this study to assess the feasibility, acceptability, and safety of a personalized exercise training program adapted from Gerofit to improve physical health and quality of life for adults with SCD

Detailed description

The purpose of this study is to adapt and pilot the Gerofit personalized exercise intervention for older adults with sickle cell disease (age ≥ 40 years). The Sickle Cell Disease Functional Assessment (SCD-FA) will be performed at steady state at baseline and every 3 months to track progress. Endpoints include feasibility, acceptability, and safety. All participants will be interviewed to identify barriers and facilitators to exercise and how to better optimize the exercise intervention.

Interventions

BEHAVIORALGerofit Exercise Program

The tele-Gerofit exercise intervention has training focused on meeting the physical activity guidelines and incorporating cardiovascular, strength, and balance training. Sessions will also include a mindfulness component, warm up, cool-down, and safety checks. Exercises are personalized to each person's functional status. Intensity of exercises will be determined by participants providing a rating of perceived exertion (RPE) on a scale of 0 (easy) to 10 (very hard) throughout the session. Initial exercise sessions will start at low-intensity and will gradually increase the duration and intensity to allow each person to reach recommended exercise levels at their own pace. Exercises are done virtually via Zoom. Each cohort will have 5-8 participants. The exercise program will be optimized after each cohort with modifications based on participant and exercise expert feedback.

Participant flow

Pre-assignment details

One participant was withdrawn by the PI due to weekly hospitalizations and never started the program. Two participants consented but never completed the safety orientation and never started the program. Both cited a busy schedule and inability to make the time commitment.
