About this study
Official title: Assessing Cognitive Improvements, Brain Neuroplasticity and the Role of Genetic Factors After Aerobic Exercise in Sedentary Adults
The overall goal of the proposed study is to evaluate the effects of an 8-week aerobic exercise program on cognition and determine the relationship between cognitive improvements and Transcranial Magnetic Stimulation (TMS) neuroplasticity.
Read the detailed description
The overall goal of the proposed study is to evaluate the effects of an 8-week aerobic exercise program on cognition and determine the relationship between cognitive improvements and neuroplasticity. The primary study aims include: 1) Quantify improvements in cognitive performance after 8 weeks (150 min per week) of moderate intensity aerobic exercise in sedentary adults ≥ 55 years of age; 2) Determine an association between changes in plasticity, aerobic capacity, and cognitive performance overall and by cognitive domain, after 8 weeks of moderate intensity aerobic exercise in sedentary adults ≥ 55 years of age.
Due to challenges posed by the COVID-19 pandemic, social distancing practices, and aiming to create a feasible scenario to continue the current study, we propose an additional option to safely adapt study methods to deliver the study in a home-based, fully remote manner. Importantly, this scenario also presents as an opportunity to collect meaningful data on our specific aims while translating this successful research program into a remote/home-based mode of delivery. A remote/home based option may also yield valuable preliminary data that will be relevant for planning future exercise studies in aging adults in the present "new normal". Therefore, this research project consist of two equivalent options:
Option A: Current, IRB-approved, in-person methods pending appropriateness based on current University of Miami recommendations and standard operating procedures as it relates to the COVID-19 pandemic.
Option B: Remote option of current methods to maximize recruitment. This will be the only option until the study team obtains approval to resume Option A (as per University's safety guidelines).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Aerobic ExerciseBehavioural
Participants will be fitted with a heart rate monitor and will be instructed to walk (or trot) to maintain 55-64% of maximal heart rate (determined by exercise test) for the first 4-weeks of exercise or to maintain 65-90% of maximal heart rate (determined by exercise test) for the second 4-weeks of exercise during each session. Participants are provided the option to participate remotely due to COVID-19 pandemic, as detailed below. Both options are designed to be equivalent in intervention and outcome measures.
Option A: Current, IRB-approved, in-person methods pending appropriateness based on current University of Miami recommendations and standard operating procedures as it relates to the COVID-19 pandemic.
Option B: Remote option of current methods to maximize recruitment. This will be the only option until the study team obtains approval to resume Option A (as per University's safety guidelines).
| Study group | Role | What they receive |
|---|---|---|
| Exercise group (All participants) | Experimental | Each participant will engage in 60 minute in-person daily sessions delivered 3 times/week for 8 consecutive weeks (a total of 24 sessions). Participants were provided with option to participate remotely due to COVID-19 pandemic. Receives: Behavioral: Aerobic Exercise |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in TMS Plasticity Measures
Index of the duration of the Theta-burst stimulation (TBS)-induced modulation of corticospinal excitability. This outcome measure refers to the identification of the time point (T5, T10, T15, T20 and T30). at which the normalized motor evoked potential (MEP) amplitude returns to baseline values (T0 or Baseline). This measure will be in Minutes Post Theta-Burst stimulation. This is a neurophysiological measure, and no group-based norms apply.
Measured: Baseline and Post-intervention (after 8 weeks of exercise)
Cognitive Performance (RBANS)
Cognitive performance will be assessed using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) a neuropsychological test battery in executive function, processing speed, learning, and language. It is made up of a series of twelve subtests that take approximately 30 minutes. For each of these, a lower number correct is indicative of a higher cognitive deficit. Subtests are their scales are: RBANS Semantic Fluency (0-unlimited), RBANS Picture Naming (0-10), RBANS List Learning (0-40), RBANS List Recall (0-10), RBANS Story Memory (0-24), RBANS Story Recall (0-12), RBANS List Recognition (0-20), RBANS Digit Span (0-16), RBANS Figure Recall (0-20), RBANS Coding (0-89), RBANS Figure Copy (0-20), RBANS Line Orientation (0-20).
Measured: Baseline and Post-intervention (after 8 weeks of exercise)
Cognitive Performance (DKEFS)
Cognitive performance will be assessed using a neuropsychological test battery in executive function, processing speed, learning, and language. The D-KEFS Verbal Fluency Test measures the ability to generate words fluently in an effortful phonemic format (letter fluency),from overlearned concepts (category fluency), and simultaneously shifting between overlearned concepts (category switching). Raw scores (correct responses, correct number of switches between categories) are converted to scaled scores with a mean of 10 and a standard deviation of 3. Higher scores reflect higher verbal fluency, and an increase in score pre-post would indicate improvement.
Measured: Baseline and Post-intervention (after 8 weeks of exercise)
Cognitive Performance (Digital Span)
Digital span - Subtest of the Wechsler Adult Intelligence Scale fourth edition; Three sections: Digits Forward, Digits Backward, and Digits Sequencing. For each section, min. raw score value: 0; max. raw score value: 16. Higher the score, better the outcome.
Measured: Baseline and Post-intervention (after 8 weeks of exercise)
Secondary outcomes (4)
Circulating Markers of Endothelium Function (BDNF)
Blood samples will be collected to measure: brain-derived neurotrophic factor (BDNF) levels (measured as pg/mL).
Measured: Baseline
Change in Cardiorespiratory Fitness
Heart rate recovery (HRR) is the primary measure for cardiorespiratory fitness. HRR is defined as the change in the heart rate from the peak of exercise to the heart rate after 1-min (HRR-1) and 2-min test cessation (HRR-2).
Measured: Baseline and Post-intervention (after 8 weeks of exercise)
Circulating Markers of Endothelium Function (VEGF)
Blood samples will be collected to measure vascular endothelial growth factor (VEGF) (measured as pg/mL).
Measured: Baseline
Circulating Markers of Endothelium Function (Hs-CRP)
Blood samples will be collected to measure high sensitivity C reactive protein (HS-CRP) (measured as mg/L).
Measured: Baseline

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03804528, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Sep 2024; AzTrials last refreshed its copy on 8 Nov 2026.
