PRIMARY OBJECTIVE I. Determine the preliminary efficacy of socially-enhanced supervised group exercise on cancer loneliness and social isolation in older PCS.
SECONDARY OBJECTIVE:
I. Examine potential mediators of the effect of socially-enhanced supervised group exercise on cancer loneliness (social support for exercise, cancer-related negative social expectations and self-efficacy).
TERTIARY OBJECTIVE:
I. Determine the preliminary efficacy of socially-enhanced supervised group exercise on mental health (anxiety, depressive symptoms) and physical health (fatigue and physical function) in older PCS.
OUTLINE: PCS are randomized to 1 of 3 arms.
ARM I: PCS participate in online supervised group exercise training led by a certified exercise instructor over 60 minutes with additional 15-minute pre-exercise social time 3 times weekly over 6 months.
ARM II: PCS participate in online supervised group exercise training led by a certified exercise instructor over 60 minutes 3 times weekly over 6 months.
ARM III: PCS participate in independent exercise training following written manual and video over 60 minutes 3 times weekly over 6 months. Men have two individual training sessions with the trainer to learn the exercise program and then the trainer will check in monthly to adjust the program as necessary.
