Kokeellinen: Fyysisen aktiivisuuden kunto (PAC)
Koehenkilöitä pyydetään osallistumaan virtuaalisiin harjoituksiin 3 kertaa viikossa 1 vuoden ajan.
|
Koehenkilöt osallistuvat virtuaalisiin ryhmäharjoituksiin 3x/viikko 1 vuoden ajan.
Jokaista koehenkilöä rohkaistaan kävelemään kohtuullisella intensiteetillä (tavoitesyke (HR) = 40-59 % HR-reservi) leposykkestä ja iästä riippuen.
Koehenkilöt tekevät itse aerobista harjoittelua ja vastusharjoituksia suoritetaan virtuaaliharjoitteluissa ohjaajan kanssa 1 tunti/vrk 3 päivää/viikko 1 vuoden ajan.
Harjoitusistunnoissa näitä osallistujia pyydetään kirjaamaan suoritettujen harjoitusten mittaukset ja heitä voidaan pyytää mittaamaan sykemittauksia (arvioitu tunnustelulla 20 sekunnin ajan) ja havaitun rasituksen nopeudesta (RPE).
Heitä pyydetään toimittamaan nämä tiedot sisältävä harjoitusloki.
Harjoituslokien ja harjoitteluasiantuntijoiden tietueiden tiedot tarkistetaan edistymisen, tasaisen kohtalaisen intensiteetin saavuttamisen ja aerobisen ja voimaharjoittelukomponenttien määrätyn keston suhteen.

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

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
Aikaikkuna: 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
Aikaikkuna: 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.

Aiotko jakaa yksittäisten osallistujien tietoja (IPD)?
IPD-suunnitelman kuvaus
Tietodokumentaatio ja tunnistamattomat tiedot tallennetaan jaettavaksi sovellettavien lakien ja määräysten mukaisesti. Tiedot ovat saatavilla nimettömänä ja .csv-muodossa muoto. Tiedot jaetaan viemällä tiedot RedCapista .csv-tiedostoon tiedosto arkistoitu tutkimuksen päätutkijan institutionaaliseen profiiliin North Carolina Greensboron yliopiston (UNCG) University Librariesin institutionaalisen arkiston North Carolina Digital Online Collection of Knowledge and Scholarship (NC DOCKS) kautta.
Tietoja jaetaan myös Global Alzheimer's Association Interactive Networkin (GAAIN) kautta. Se on liittoutunut tietojärjestelmä, joka on suunniteltu edistämään tiedon jakamista ja yhteistyön kehittämistä Alzheimerin tautiin liittyvistä tiedoista kiinnostuneille tutkijoille. Kiinnostuneet tutkijat voivat tutkia metadataa PAAD-2:sta ja muista tutkimuksista. Kun kumppaniksi tulee, PAAD-2:n kuvaus ja linkki päätutkijaan ovat saatavilla osoitteessa www.gaain.org.
