Intervention / Traitement |
|---|---|
|
Expérimental: Condition d'activité physique (PAC)
Les sujets seront invités à assister à des séances d'exercices virtuels 3 fois par semaine pendant 1 an.
|
Les sujets assisteront à des séances d'exercices virtuels en groupe 3x/semaine pendant 1 an.
Chaque sujet sera encouragé à marcher à une intensité modérée (fréquence cardiaque cible (FC) = 40-59 % de réserve FC) en fonction de la fréquence cardiaque au repos et de l'âge.
Les sujets effectueront des exercices aérobies par eux-mêmes et des exercices de résistance seront complétés lors de séances d'exercices virtuels avec un instructeur 1 heure/jour pendant 3 jours/semaine pendant 1 an.
Lors des séances d'exercices, ces participants seront invités à enregistrer les mesures des exercices effectués et peuvent être invités à fournir des mesures de la fréquence cardiaque (évaluée par palpation pendant 20 secondes) et du taux d'effort perçu (RPE).
Il leur sera demandé de soumettre des journaux d'exercices fournissant ces informations.
Les données des journaux d'exercices et des dossiers des spécialistes de l'exercice seront examinées pour vérifier la progression, l'atteinte constante d'une intensité modérée et la durée prescrite des composantes d'entraînement aérobique et de musculation.

Change in Performance on the Cognitive Domain of Executive Function as Measured With Stroop Interference Reaction Time (RT)
Délai: Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months)
|
Change in executive function will be assessed by comparing Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months) performance on Stroop Interference.
Stroop interference is calculated using reaction time (RT) data from correct trials and the following formula: Stroop Interference RT = Stroop Incongruent RT - (average (Stroop Congruent RT , Stroop Neutral RT)).
Stroop Congruent is also known as Stroop Word, and Stroop Neutral is also known as Stroop Color.
RT is recorded in msec and a larger score is indicative of greater interference (worse performance)

|
Change in Performance on the Cognitive Domain of Executive Function as Measured With Trail Making Test Interference
Délai: Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months)
|
Change in executive function will be assessed by comparing Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months) performance on the Comprehensive Trail Making Test (TMT) interference.
TMT interference is calculated as total time to complete TMT B (also called Trail 5) minus the total time to complete TMT A (also called Trail 1)which were both recorded in seconds.
TMT interference is, therefore, recorded in seconds with a larger score indicative of greater interference (worse performance)

Change in Performance on the Cognitive Domain of Executive Function as Measured With NIH Toolbox Dimensional Change Card Sort
Délai: Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months)
|
Change in executive function will be assessed by comparing Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months) performance on the NIH Toolbox Dimentional Change Card Sort Test (DCCS).
We used the recommended outcome of the DCCS computed score.
This is calculated automatically within the NIH Toolbox based upon a two-stage process combining a score of 0-5 from the accuracy data with a score of 0-5 from the reaction time data.
Thus, scores range from 0-10 with a higher score indicative of better performance.

Change in Performance on the Cognitive Domain of Memory as Measured With the Mnemonic Similarity Test
Délai: Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months)
|
Change in memory will be assessed by comparing Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months) Lure Discimination Index (LDI) on the Mnemonic Similarity Test (MST).
The MST was created based upon the publicly available and validated instructions and stimuli provided by the creators of the task (Stark, Kirwan, & Stark, 2019).
Equivalent versions of the test are administered so participants see different stimuli at each testing session and those stimuli were counterbalanced to rotate through the different item types.
The formula for calculating the LDI is: p(similar|lure) - p(similar|foil) where p(similar|lure) = Total # of "similar" responses to lure items / 36 and p(similar|foil) = Total # "similar" responses to foil items / 36.
Scores range from -1 to +1 with a larger score indicating better discrimination performance.

Change in Cardiorespiratory Fitness
Délai: Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months)
|
Fitness will be assessed by comparing predicted VO2max at Pre-Test, Mid-Test (~6 months), and Post-Test (~12 months).
Fitness will be assessed using a submaximal graded aerobic exercise test performed on a treadmill.
Oxygen uptake (VO2) at each stage is estimated based on the treadmill speed and grade during a ramped exercise protocol performed until volitional exhaustion or test termination due to symptom limitations.
The VO2max estimation uses the slope of the regression line between the heart rates (HR) of the last two stages to extrapolate to the participant's predicted VO2 at their age-predicted max HR (220-age).
If HR at either of the last two stages is <110, VO2 could not be reliably calculated, and we consider the participant to have insufficient data (ID).
We have explored other options for estimating VO2 max, but believe this is the best option available.

Plan pour les données individuelles des participants (IPD)
Prévoyez-vous de partager les données individuelles des participants (DPI) ?
Description du régime IPD
La documentation des données et les données anonymisées seront déposées pour être partagées conformément aux lois et réglementations applicables. Les données seront disponibles dans un état anonyme anonymisé et dans un fichier .csv format. Les données seront partagées en exportant les données de RedCap dans un .csv fichier archivé sous le profil institutionnel du chercheur principal de l'étude avec le référentiel institutionnel des bibliothèques universitaires de l'Université de Caroline du Nord à Greensboro (UNCG) North Carolina Digital Online Collection of Knowledge and Scholarship (NC DOCKS).
Les données seront également partagées via le Global Alzheimer's Association Interactive Network (GAAIN), un système de données fédéré conçu pour favoriser le partage de données et le développement de collaborations pour les chercheurs intéressés par les données liées à la maladie d'Alzheimer. Les scientifiques intéressés peuvent explorer les métadonnées de PAAD-2 et d'autres études. En devenant partenaire, une description de PAAD-2 et un lien pour contacter le chercheur principal seront disponibles sur www.gaain.org.
