A randomized controlled trial of progressive resistance training in depressed elders

Area of Science:

• Gerontology
• Exercise Physiology
• Clinical Psychology

Background:

• Aging is associated with multiple losses that can contribute to depression in the elderly.
• Exercise offers a potential avenue to address these age-related losses concurrently.
• The study investigated the impact of progressive resistance training (PRT) on depression and related factors in older adults.

Purpose of the Study:

• To test the hypothesis that PRT reduces depression in older adults.
• To assess PRT's effects on physiologic capacity, quality of life, morale, function, and self-efficacy.
• To evaluate the safety and adverse events associated with PRT in this population.

Main Methods:

• A 10-week randomized controlled trial was conducted.
• Participants were adults aged 60 and above with diagnosed depression (major, minor, or dysthymia).
• Subjects were randomized to either a supervised PRT program (3x/week) or an attention-control group.

Main Results:

• 32 participants (aged 60-84) completed the study with no significant adverse events and high compliance (95%).
• PRT significantly reduced depression scores on the Beck Depression Inventory and Hamilton Rating Scale of Depression compared to controls.
• Improvements were observed in quality of life subscales (bodily pain, vitality, social functioning, role emotional) and a 33% increase in strength.

Conclusions:

• Progressive resistance training (PRT) serves as an effective antidepressant intervention for depressed elders.
• PRT positively impacts strength, morale, and quality of life in older adults.
• Training intensity was identified as a significant predictor of depression reduction.
