Overview
Brief Summary
The purpose of this study is to conduct a small-scale test of a goals-based program to help people to exercise more and learn what people like or don't like about the procedures. This program is being designed for individuals aged 45-65 from the Black community. Low levels of physical activity are related to health problems such as heart disease, diabetes, and cognitive decline. People of color are more negatively impacted by these conditions and have also historically been underrepresented by research seeking to increase physical activity. The investigators have developed this goals-based exercise promotion program with the help of a Black-led community-based organization (The Gyedi Project) and a Community Advisory Board made up of stakeholders in the Black community, and now the investigators are conducting a trial of its feasibility and acceptability.

Outcomes
Primary Outcomes
Blood Pressure
Time Frame: Baseline, Visit 14 (~2 months after baseline)
Blood pressure of all participants is collected before intervention
Activity Levels
Time Frame: Baseline, Visit 14 (~2 months after baseline)
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.
Sleep levels
Time Frame: Baseline, Visit 14 (~2 months after baseline)
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.
Physical Activity Recall
Time Frame: Baseline, Visit 14 (~2 months after baseline)
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.
Identity
Time Frame: Baseline
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.
Exercise Behavior
Time Frame: Baseline, Visit 14 (~2 months after baseline)
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.
Theoretical Mediators of Exercise Behavior
Time Frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)
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.
Heart Rate Variability
Time Frame: Baseline, Visit 14 (~2 months after baseline)
Heart Rate Variability is measured using chest strap monitor.
Heart Rate
Time Frame: Baseline, Visits 1-14 (all visits)
HR is measured using chest strap monitor.
Physical Performance
Time Frame: Baseline, Visit 14 (~2 months after baseline)
Short Physical Performance Battery. Physical performance measured with repeated chair stands, three balance tests (side-by-side, semi-tandem, tandem), timed walking.
Ventilatory Threshold
Time Frame: Baseline
Talk Test. Graded treadmill test where intensity is increased at intervals to determine participant's ventilatory threshold.
Perceived Exertion
Time Frame: Visit 2-13 (~2 visits/week)
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).
Pain Levels
Time Frame: Visit 2-13 (~2 visits/week)
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).
Affective Valence
Time Frame: Visit 2-13 (~2 visits/week)
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).
Affective Arousal
Time Frame: Visit 2-13 (~2 visits/week)
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).
Enjoyment
Time Frame: Visit 2-13 (~2 visits/week)
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).
Exercise Check-In
Time Frame: Daily between visit 13 and 14 (~1 month)
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
Study Feedback
Time Frame: Visit 14 (~2 months after baseline)
An investigator led interview to pilot study participants' experience of the intervention and suggestions for improvement
Exercise Benefits and Barriers
Time Frame: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)
A 10 item scale assessing perceived benefits of and barriers to exercise
Anthropometrics
Time Frame: Baseline
Height, weight, waist circumference, and hip circumference will be measured
Exercise Aligned with Black Identity
Time Frame: Baseline
Assessment of the extent to which 7 common exercises are aligned with Black identity
Mental Status
Time Frame: Baseline
Pfeiffer Mental Status. Assessment of cognitive deficits at baseline.
Diet
Time Frame: Baseline

A short dietary assessment instrument for measuring fruit and vegetable intake over the past month.
Physical Activity
Time Frame: Baseline
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.
