Experimental: Zustand körperlicher Aktivität (PAC)
Die Probanden werden gebeten, ein Jahr lang dreimal pro Woche an virtuellen Übungseinheiten teilzunehmen.
|
Die Probanden nehmen 1 Jahr lang 3x/Woche an virtuellen Gruppenübungen teil.
Jeder Proband wird ermutigt, mit mäßiger Intensität (Zielherzfrequenz (HR) = 40-59 % HR-Reserve) zu gehen, abhängig von der Ruhe-HF und dem Alter.
Die Probanden führen Aerobic-Übungen alleine durch und Widerstandsübungen werden in virtuellen Übungssitzungen mit einem Ausbilder 1 Stunde/Tag für 3 Tage/Woche für 1 Jahr absolviert.
Bei den Übungssitzungen werden diese Teilnehmer gebeten, Messungen der absolvierten Übungen aufzuzeichnen, und können gebeten werden, Messungen der Herzfrequenz (bewertet durch Palpation für 20 Sekunden) und der Rate der wahrgenommenen Anstrengung (RPE) bereitzustellen.
Sie werden gebeten, Übungsprotokolle mit diesen Informationen einzureichen.
Daten aus Übungsprotokollen und Aufzeichnungen von Übungsspezialisten werden auf Hinweise auf Progression, konsistentes Erreichen einer moderaten Intensität und in Bezug auf die vorgeschriebene Dauer der Aerobic- und Krafttrainingskomponenten überprüft.

Kein Eingriff: Übliche Pflegekontrolle (UCC)
Teilnehmer an der üblichen Pflegekontrolle behalten ihre normalen Gesundheitspraktiken ein Jahr lang bei.
Die Teilnehmer erhalten alle zwei Wochen einen Gesundheitsnewsletter und werden alle zwei Wochen kontaktiert, um Fragen zu beantworten und sich über den Gesundheitszustand des Teilnehmers zu erkundigen.
Die selbstberichtete körperliche Aktivität der Teilnehmer wird monatlich bewertet.
Auf diese Weise werden die Teilnehmer jede Woche von den Mitarbeitern kontaktiert.
Teilnehmer der üblichen Pflegekontrolle, die alle studienbezogenen Aktivitäten, einschließlich Vor-, Mittel- und Nachtests, abschließen, erhalten nach dem Posttest eine kurzfristige YMCA-Mitgliedschaft.

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

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
Zeitfenster: 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
Zeitfenster: 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.
