Interventie / Behandeling |
|---|---|
|
Experimenteel: Lichamelijke Activiteit Conditie (PAC)
Proefpersonen wordt gevraagd om gedurende 1 jaar 3 keer per week virtuele oefensessies bij te wonen.
|
De proefpersonen zullen gedurende 1 jaar 3x/week virtuele groepsoefeningen bijwonen.
Elke proefpersoon wordt aangemoedigd om met een matige intensiteit te lopen (doelhartslag (HR) = 40-59% HR-reserve), afhankelijk van HR in rust en leeftijd.
De proefpersonen voeren zelf aerobe oefeningen uit en weerstandsoefeningen worden voltooid in virtuele trainingssessies met een instructeur, 1 uur per dag gedurende 3 dagen per week gedurende 1 jaar.
Tijdens de oefensessies wordt deze deelnemers gevraagd om metingen van de voltooide oefeningen op te nemen en kan worden gevraagd om metingen van de hartslag (beoordeeld door palpatie gedurende 20 seconden) en snelheid van waargenomen inspanning (RPE) te geven.
Ze zullen worden gevraagd om trainingslogboeken in te dienen met deze informatie.
Gegevens uit trainingslogboeken en records van trainingsspecialisten zullen worden beoordeeld op bewijs van progressie, consistent bereiken van matige intensiteit en met betrekking tot de voorgeschreven duur van de aerobe en krachttrainingscomponenten.

Geen tussenkomst: Gebruikelijke zorgcontrole (UCC)
Deelnemers aan de gebruikelijke zorgcontrole behouden gedurende 1 jaar hun normale gezondheidspraktijken.
Deelnemers ontvangen een tweewekelijkse gezondheidsnieuwsbrief en worden tweewekelijks gecontacteerd om eventuele vragen te beantwoorden en te informeren naar de gezondheid van de deelnemer.
De zelfgerapporteerde fysieke activiteit van de deelnemers wordt maandelijks beoordeeld.
Op deze manier worden deelnemers wekelijks benaderd door medewerkers.
Gebruikelijke zorgcontroledeelnemers die alle studiegerelateerde activiteiten voltooien, inclusief pre-, mid- en post-test, ontvangen na de post-test een korte termijn YMCA-lidmaatschap.

Change in Performance on the Cognitive Domain of Executive Function as Measured With Stroop Interference Reaction Time (RT)
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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
Tijdsspanne: 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.

Bent u van plan om gegevens van individuele deelnemers (IPD) te delen?
Beschrijving IPD-plan
Gegevensdocumentatie en geanonimiseerde gegevens worden gedeponeerd om te worden gedeeld in overeenstemming met toepasselijke wet- en regelgeving. Gegevens zullen beschikbaar zijn in een geanonimiseerde anonieme staat en in een .csv formaat. Gegevens worden gedeeld door de gegevens vanuit RedCap te exporteren naar een .csv bestand gearchiveerd onder het institutionele profiel van de hoofdonderzoeker van de studie bij University of North Carolina Greensboro (UNCG) Universitaire bibliotheken institutionele repository North Carolina Digital Online Collection of Knowledge and Scholarship (NC DOCKS).
De gegevens zullen ook worden gedeeld via het Global Alzheimer's Association Interactive Network (GAAIN), een gefedereerd gegevenssysteem dat is ontworpen om het delen van gegevens en de ontwikkeling van samenwerkingsverbanden voor onderzoekers die geïnteresseerd zijn in gegevens over de ziekte van Alzheimer te bevorderen. Geïnteresseerde wetenschappers kunnen metadata van PAAD-2 en van andere onderzoeken verkennen. Door partner te worden, zullen een beschrijving van PAAD-2 en een link om contact op te nemen met de hoofdonderzoeker beschikbaar worden gesteld op www.gaain.org.
