What is the purpose of this trial?

This trial aims to explore how aerobic exercise might benefit brain health and thinking skills in older adults who have previously experienced depression but are not currently depressed. It will compare a group engaging in regular aerobic activities, like walking or cycling, with another group participating in social activities to determine if exercise can reduce the risk of dementia. The trial is ideal for those aged 60 or older who have experienced depression since age 55, are not currently experiencing a depressive episode, and engage in less than 100 minutes of exercise per week. As an unphased trial, this study offers participants the opportunity to contribute to understanding how lifestyle changes can impact brain health.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the study team for guidance.

What prior data suggests that aerobic exercise is safe for older adults with remitted late-life depression?

Research has shown that aerobic exercise is generally safe and can improve mental health in older adults. One study found that adding aerobic exercise to depression treatments helped with thinking and memory. Other research suggests that aerobic exercise might enhance the effects of antidepressants in older people safely.

Overall, these findings indicate that aerobic exercise is not only safe for older adults but also very beneficial for their mental health. Studies report no major safety concerns, making it well-tolerated. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Unlike traditional treatments for late-life depression, which often rely on medications like antidepressants or psychotherapies, the aerobic exercise approach focuses on enhancing mental health through physical activity. This method is unique because it offers a non-pharmacological option that can be tailored to individual fitness levels, promoting not only mental but also physical well-being. Researchers are excited about this approach because exercise has the potential to improve mood and cognitive function by boosting endorphins and enhancing brain health, offering a holistic way to tackle depression in older adults. Additionally, the social engagement aspect provides a sense of community and support, which can further enhance emotional wellness. This dual approach of physical activity combined with social interaction makes it a promising alternative or complement to existing therapies.

What evidence suggests that aerobic exercise could be an effective treatment for late-life depression?

Research shows that aerobic exercise, such as walking or cycling, can enhance mood and brain function in older adults. In this trial, participants will engage in aerobic exercise as one of the treatment arms, involving 150 minutes of moderate-intensity exercise per week. Studies have found that regular aerobic exercise becomes especially effective when combined with other treatments for depression. It also supports heart and lung health, potentially benefiting the brain. Overall, aerobic exercise could improve mental health and reduce the risk of dementia in older adults who have experienced depression. ^{4 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• At-home AE
• Fitness for Brain Optimization
• On-site AE
• Social Engagement

Trial Overview The study tests the effects of aerobic exercise on brain function in older adults with remitted Late-Life Depression. Participants will engage in either on-site or at-home aerobic exercises versus social engagement activities to assess cognitive benefits.

How Is the Trial Designed?

Group I: Aerobic Exercise Experimental Treatment 2 Interventions

The Aerobic Exercise (AE) condition will involve 150-minutes of moderate-intensity AE per week for 6-months and will involve a graded decline in supervision. Supervised AE will occur in groups, though each participant's AE prescription will be personalized based on baseline exercise capacity, as assessed by a maximal cardiopulmonary fitness test. Supervised AE sessions will involve the treadmill, elliptical, and/or bike, and routines will be varied to promote adherence. Supervised AE sessions will gradually increase to 50-minutes per session; however, participants will be encouraged to engage in home-based AE sessions according to their own preference of length and frequency in order to achieve 150 minutes of AE per week.

Group II: Social Engagement Active Control 1 Intervention

The Social Engagement (SE) condition will be designed to control for the social component of the AE intervention (i.e., supervised on-site sessions with professional staff, frequent phone contact from study staff). A variety of enjoyable group-based activities centered around the dimensions of wellness (spiritual wellness, physical wellness, emotional wellness, etc.) will be scheduled throughout the intervention. This condition will involve once weekly meetings (grand total of \~26 sessions). Some participants will meet in-person and others will meet remotely via zoom (this will vary week to week) to increase flexibility to accommodate participant availability to attend as many sessions as possible.

Higher cardiorespiratory fitness (CRF) is linked to a lower risk of purchasing antidepressants or anxiolytics, with each 1-MET increase in CRF reducing the risk by 4%, based on a study of 32,603 participants from the Trøndelag Health Study.

Men and younger adults (ages 20-65) with intermediate to high CRF levels showed a significantly reduced risk of needing these medications, suggesting that improving fitness may be a protective factor against mental health medication use.
