Exercise Adherence and Cognitive Decline

Blood Pressure

Blood pressure of all participants is collected before intervention

Time frame: Baseline, Visit 14 (~2 months after baseline)

Activity Levels

Exercise Intensity (PAR). Answers are direct (ex. how many hours active) and not scaled. Information is requested for the week and the past 3 months.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Sleep levels

Exercise Intensity (PAR). Answers are direct (ex. how many hours did you sleep) and are not scaled. Information is requested for the past 7 days.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Physical Activity Recall

Exercise Intensity (PAR). Answers are direct (ex. how many hours did you sleep) and are not scaled. Information is requested for the past 7 days.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Identity

Multidimensional Black Identity Scale to collect information on identity. Questions are about personal identity relating to the Black community on a scale of 1-7, 1 being strongly disagree and 7 being strongly agree. Higher scores indicate a stronger agreement with that dimension of Black identity. Scores are summed as subscales and averaged to obtain an average score.

Time frame: Baseline

Exercise Behavior

CHAMPS. The survey collects quantitative data looking at the approximate total hours per week spent doing various activities, both physical and social.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Exercise Behavior

L-Cat. Single question that asks about frequency/rigor of physical activity, with six potential answers ranging from no physical activity to daily physical activity.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Theoretical Mediators of Exercise Behavior

Intrinsic Motivation Inventory. Questions relate to how participants think or feel about physical activity, with answers ranging from 1 (strongly disagree) to 7 (strongly agree). Broader scores are broken up into subscales; final subscale scores are summed and averaged. Higher scores indicate higher agreement with that subscale.

Time frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)

Theoretical Mediators of Exercise Behavior

Self-Efficacy. 9 questions about confidence in exercise on scale of 1 (disagree strongly) to 7 (agree strongly). Higher scores indicate higher perceived confidence in doing that activity. Total scores are summed.

Time frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)

Theoretical Mediators of Exercise Behavior

Exercise Intention Survey. Scored on a Likert scale from 1 (strongly disagree) to 7 (strongly agree) to indicate level of agreement to statements related to intention to exercise. Scores are summed to produce a total score. Higher scores indicate stronger intention to exercise, lower scores indicate weaker intention.

Time frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)

Theoretical Mediators of Exercise Behavior

Exercise Identity Score. Scored on a Likert scale from 1 (strongly disagree) to 7 (strongly agree) to indicate level of agreement to statements related to attitudes towards exercise. Scores are summed and averaged to provide an overall score. Higher scores indicate a positive attitude towards exercise, lower scores less favorable attitude.

Time frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)

Heart Rate Variability

Heart Rate Variability is measured using chest strap monitor.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Heart Rate

HR is measured using chest strap monitor.

Time frame: Baseline, Visits 1-14 (all visits)

Physical Performance

Short Physical Performance Battery. Physical performance measured with repeated chair stands, three balance tests (side-by-side, semi-tandem, tandem), timed walking.

Time frame: Baseline, Visit 14 (~2 months after baseline)

Ventilatory Threshold

Talk Test. Graded treadmill test where intensity is increased at intervals to determine participant's ventilatory threshold.

Time frame: Baseline

Perceived Exertion

A single-item measure from Borg (1973) was used to assess participants' rate of perceived exertion (RPE) during the exercise bout. Participants were asked to rate the average intensity of exercise \[at that moment/during the past ten minutes\] on a 25-point scale ranging from 6 (no exertion at all) to 20 (maximal exertion).

Time frame: Visit 2-13 (~2 visits/week)

Pain Levels

A single item measure from Borg (1998) was used to assess participants' pain levels during the exercise bout. Participants were asked to indicate how much pain they felt \[at that moment/during the past ten minutes\] on an 11-point scale ranging from 0 (nothing at all) to 10 (excruciating).

Time frame: Visit 2-13 (~2 visits/week)

Affective Valence

The Feeling Scale, a single-item measure from Hardy and Rejeski (1989), was used to assess participants' affective valence during the exercise bout. Participants were asked to indicate how they felt \[at that moment/during the past ten minutes\] on an 11-point scale ranging from -5 (very bad) to +5 (very good).

Time frame: Visit 2-13 (~2 visits/week)

Affective Arousal

The Felt Arousal Scale, a single-item measure from Svebak and Murgatroyd (1985), was used to assess participants' affective arousal during the exercise bout. Participants were asked to indicate how "worked-up" they felt \[at that moment/during the past ten minutes\] on a 6-point scale ranging from 1 (low arousal) to 6 (high arousal).

Time frame: Visit 2-13 (~2 visits/week)

Enjoyment

A single item measure from Gillman and Bryan (2015) was used to assess participants' enjoyment levels during the exercise bout. Participants were asked to indicate how enjoyable exercise was \[at that moment/during the past ten minutes\] on a 5-point scale ranging from 1 (no enjoyment at all) to 5 (a great deal of enjoyment).

Time frame: Visit 2-13 (~2 visits/week)

Exercise Check-In

Three short questions assessing if the participant planned to engage in exercise and how many minutes of moderate (0-120) and vigorous (0-60) exercise they engaged in

Time frame: Daily between visit 13 and 14 (~1 month)

Study Feedback

An investigator led interview to pilot study participants' experience of the intervention and suggestions for improvement

Time frame: Visit 14 (~2 months after baseline)

Exercise Benefits and Barriers

A 10 item scale assessing perceived benefits of and barriers to exercise

Time frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)

Anthropometrics

Height, weight, waist circumference, and hip circumference will be measured

Time frame: Baseline

Mental Status

Pfeiffer Mental Status. Assessment of cognitive deficits at baseline.

Time frame: Baseline

Physical Activity

Godin Survey. This survey measures time spent in moderate, strenuous or light activity and has been modified to include time spent sitting over a typical 7 day period. Scores are summed and a range is used to quantify how active/sedentary a participant is.
