Экспериментальный: Состояние физической активности (PAC)
Субъектам будет предложено посещать виртуальные тренировки 3 раза в неделю в течение 1 года.
|
Субъекты будут посещать виртуальные групповые занятия 3 раза в неделю в течение 1 года.
Каждому субъекту будет предложено ходить с умеренной интенсивностью (целевая частота сердечных сокращений (ЧСС) = 40-59% резерва ЧСС) в зависимости от ЧСС в покое и возраста.
Субъекты будут выполнять аэробные упражнения самостоятельно, а упражнения с отягощениями будут выполняться в виртуальных тренировках с инструктором по 1 часу в день в течение 3 дней в неделю в течение 1 года.
На занятиях по упражнениям этих участников попросят записывать показатели выполненных упражнений и могут попросить предоставить показатели частоты сердечных сокращений (оценивается пальпацией в течение 20 секунд) и скорости воспринимаемой нагрузки (RPE).
Им будет предложено предоставить журналы упражнений, содержащие эту информацию.
Данные из журналов упражнений и записей специалиста по упражнениям будут проверены на наличие признаков прогресса, последовательного достижения умеренной интенсивности и в отношении предписанной продолжительности аэробных и силовых компонентов тренировки.

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