Intervención de ejercicios de Gerofit para adultos mayores con enfermedad de células falciformes (estudio SICKLE-FIT) (SICKLE-FIT)

Experimental: Ejercicio

Cada grupo de 5 a 8 participantes hará ejercicio 3 días a la semana durante un máximo de 12 semanas. Las sesiones de ejercicio serán virtuales.

Conductual: Programa de ejercicios Gerofit

La intervención de ejercicios de tele-Gerofit tiene un entrenamiento enfocado a cumplir con las pautas de actividad física e incorporar entrenamiento cardiovascular, de fuerza y ​​de equilibrio. Las sesiones también incluirán un componente de atención plena, calentamiento, enfriamiento y controles de seguridad. Los ejercicios se personalizan según el estado funcional de cada persona. La intensidad de los ejercicios será determinada por los participantes que proporcionen una calificación de esfuerzo percibido (RPE) en una escala de 0 (fácil) a 10 (muy difícil) a lo largo de la sesión. Las sesiones iniciales de ejercicio comenzarán con una intensidad baja y aumentarán gradualmente la duración y la intensidad para permitir que cada persona alcance los niveles de ejercicio recomendados a su propio ritmo. Los ejercicios se realizan virtualmente a través de Zoom. Cada cohorte tendrá de 5 a 8 participantes. El programa de ejercicios se optimizará después de cada cohorte con modificaciones basadas en los comentarios de los participantes y expertos en ejercicios.

Feasibility, as Measured by Number of Participants Completing at Least 50% of the Exercise Sessions

Safety, as Measured by Number of Participants With Moderate or Severe Adverse Events

Number of participants with one or more moderate or severe adverse events within 48 hours after each exercise session.

Acceptability, as Measured by the Number of Participants Reporting the Intervention as Acceptable

Acceptability of the exercise program was measured on a scale of 1-10, where 1= severe dislike and 10 = absolute enjoyment. Reported as the number of participants with scores of 8-10.

Percent of Participants With Clinically Meaningful Change in Mobility as Measured by Usual Gait Speed

Reported as the percent change in usual walking speed on a 4.57 meter (15 feet) walking course.

Percent of Participants With Clinically Meaningful Change in Balance as Measured by Timed Up and Go

Performance test of physical mobility. This measures the number of seconds it takes to stand up from a standard chair (46cm), walk a distance of 10 ft (3 meters), turn back to the chair, and sit down again.

Percent of Participants With Clinically Meaningful Change in Aerobic Endurance as Measured by Six-Minute Walk Test (6MWT)

Measure of aerobic endurance. The participant walks as fast and as safely as possible for 6 minutes with prompts given every minute. Distance traveled in 6 minutes is recorded.

Percent of Participants With Clinically Meaningful Change in Upper Body Strength as Measured by Grip Strength

Measure of upper body strength. Jamar hydraulic hand dynamometer (Jamar Technologies) was used to measure grip strength in triplicate for both hands while subject remains seated. The greatest value was used in analysis.

Percent of Participants With Clinically Meaningful Change in Lower Body Strength as Measured by 30-second Chair Stand

30-second chair stand is a measure lower body strength. The participant sits in a folding chair without arms with chair pressed against the wall and stands up and sits back down with arms across their chest as many times as possible in 30 seconds.

Percent of Participants With Improved Quality of Movement Measured by Functional Movement Screen

Includes deep squat and mobility test of upper and lower extremities. This is measure of squat quality/form.
