NCT06110897

Brief Summary

Depression is a leading cause of disability worldwide and current treatments are ineffective for many people. This trial will investigate the efficacy of a 16-week high vs low dose resistance exercise training program for the treatment of Major Depressive Disorder (MDD) in 200 adults.

Outcome Measures

Primary Outcomes (4)

  • Change in depressive symptom severity measured by GRID Hamilton Depression Rating Scale (GRID-HAM-D)

    The GRID-HAM-D is a clinician-completed questionnaire that will be used to rate depressive symptom severity. The questionnaire is designed for adults and is used to rate the intensity and frequency of depressive symptoms by probing mood, feelings of guilt, suicidal ideation, insomnia, agitation or retardation, anxiety, weight loss, and somatic symptoms. As recommended by the Depression Rating Scale Standardization Team, Clinical Interviewers will follow the Structured Interview Guide and use GRID scoring, in which dimensions of intensity and frequency of a symptom are rated independently for each item. Higher scores reflect greater symptom severity, categorized as Normal (0-7), Mild Depression (8-13), Moderate Depression (14-18), Severe Depression (19-22), and Very Severe Depression (\>23).

    Weeks 0, 8, 16, 26, 52

  • Change in self-reported depression symptom severity measured by Quick Inventory of Depressive Symptoms (QIDS)

    This is a self-administered 16-item questionnaire that assesses the severity of nine depressive symptoms in the last 7 days. Each item is rated on a 4-point scale (0-3), with total scores ranging from 0-27. Higher scores indicate more severe depression. This assessment is recommended because it is free, easily administered as a self-reported instrument for adults, and captures general symptoms of depression.

    Weeks 0, 1-16 (once per week across the intervention), 26, 52

  • Cerebral mean blood velocity

    Cerebral blood velocity will be measured under supine, resting conditions using non-invasive techniques following 10 min of quiet rest in a dimly lit room. Measurements will be taken from the middle (MCA, primary outcome) and anterior cerebral artery (ACA, secondary outcome) following standardized, recommended insonation protocols using 2 megahertz (MHz) transcranial Doppler (TCD) probes secured to the temporal window via a headset. MCA blood velocity waveforms will be collected over a 90-sec epoch and averaged. MCA mean blood velocity will be calculated using a standard algorithm implemented on the device.

    Weeks 0, 8, 16, 26, 52

  • Cerebral blood velocity pulsatility

    Cerebral blood pulsatility will be measured using the same techniques and conditions described for cerebral mean blood velocity, above for the MCA (primary outcome) and ACA (secondary outcome). Cerebral pulsatility will be quantified using the pulsatility index, calculated as (systolic - diastolic velocity)/mean velocity.

    Weeks 0, 8, 16, 26, 52

Secondary Outcomes (25)

  • Changes in general self efficacy measured by New General Self-Efficacy Scale

    Weeks 0, 8, 16, 26, 52

  • Changes in RET-specific self efficacy measured by a modified version of the New General Self-Efficacy Scale

    Weeks 0, 1-16 (once per week across the intervention), 26, 52

  • Change in suicidal thoughts measured by Columbia-Suicide Severity Rating Scale (CSSRS)

    Weeks 0, 8, 16, 26, 52

  • Change in muscular strength measured by Estimated 1 Repetition Maximum (RM) Strength Test

    Weeks 0, 8, 16, 26, 52

  • Change in grip strength

    Weeks 0, 8, 16, 26, 52

  • +20 more secondary outcomes

Study Arms (2)

High Dose Resistance Exercise Training

EXPERIMENTAL

Participants will complete a 16-week, twice/week progressive program beginning at a moderate intensity. Each session will last \~60 minutes and begin and end with a 5-minute warm-up/cool-down. Training will begin with standard familiarization sessions to introduce participants to the machines, teach correct lifting techniques, and ensure participant safety and comfort with each exercise machine. Participants will perform 3 sets of 8-12 repetitions on 9 different machines (i.e., leg press, hamstring curl, quadriceps extension, chest press, lat pulldown, shoulder press, biceps curl, triceps extension) and one body weight/free-weight abdominal exercise. Workload will begin at 60% of estimated 1-RM and will systematically and progressively increase during the intervention.

Low Dose Resistance Exercise Training

ACTIVE COMPARATOR

Participants will complete a 16-week, twice/week progressive program beginning at a low intensity. Each session will last \~60 minutes and begin and end with a 5-minute warm-up/cool-down. Training will begin with standard familiarization sessions to introduce participants to the machines, teach correct lifting techniques, and ensure participant safety and comfort with each exercise machine. Participants will perform 3 sets of 8-12 repetitions on 9 different machines (i.e., leg press, hamstring curl, quadriceps extension, chest press, lat pulldown, shoulder press, biceps curl, triceps extension) and one body weight/free-weight abdominal exercise. Workload will begin at 30% of estimated 1-RM and will systematically and progressively increase during the intervention.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Be diagnosed with DSM-5 MDD, confirmed via Structured Clinical Interview for DSM-5 (SCID).
  • Have current depressive symptoms of at least mild severity defined by the Hamilton Rating Scale of Depression 17 greater than or equal to 8 (HAMD; using the GRID-HAMD evaluated by trained, masked raters)
  • Be ages 18-65
  • EITHER not taking any mental health medications or seeking other mental health treatment (e.g., behavioral, psychological) OR be on a stable mental health medication and/or treatment regimen for the past 8 weeks, and intend to maintain that regimen for the duration of the study
  • Safe to exercise based on physical activity screening questions or physician clearance
  • Willing to be randomized to either condition
  • have a Smartphone

You may not qualify if:

  • Currently pregnant, nursing, or planning to become pregnant during the trial
  • Class III+ obesity
  • Diagnosed with lifetime or current Psychosis, Mania, or Bipolar Disorder, via the SCID
  • Diagnosed with current Substance Use Disorder, via the SCID
  • Active suicidal ideation with specific plan and intent ('5' score on Suicidal Ideation from Columbia Suicide Severity Rating Scale), which would necessitate immediate emergent care
  • Exhibit behavioral disturbance (e.g., aggression, mild-moderate cognitive impairment) that would significantly interfere with study participation, as assessed by clinical research personnel
  • Currently meets resistance exercise recommendations (2 days per week) for the last 8 weeks
  • Self-reporting a concussion/traumatic brain injury within the last 3 months
  • Having cardiovascular disease, uncontrolled hypertension, or uncontrolled diabetes
