Exercise Adherence and Cognitive Decline: Engaging With the Black Community to Develop and Test a Goal-Setting and Exercise Intensity Intervention

Blood Pressure

时间窗: Baseline, Visit 14 (~2 months after baseline)

Blood pressure of all participants is collected before intervention

Activity Levels

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: 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.

Heart Rate Variability

时间窗: Baseline, Visit 14 (~2 months after baseline)

Heart Rate Variability is measured using chest strap monitor.

Heart Rate

时间窗: Baseline, Visits 1-14 (all visits)

HR is measured using chest strap monitor.

Exercise Behavior

时间窗: Baseline, Visit 14 (~2 months after baseline)

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

Physical Performance

时间窗: 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

时间窗: Baseline

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

Perceived Exertion

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: 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

时间窗: Baseline

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

Exercise Aligned with Black Identity

时间窗: Baseline

Assessment of the extent to which 7 common exercises are aligned with Black identity

Mental Status

时间窗: Baseline

Pfeiffer Mental Status. Assessment of cognitive deficits at baseline.

Physical Activity

时间窗: 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.

Theoretical Mediators of Exercise Behavior

时间窗: Baseline, Visit 12 (~1 month after baseline), Visit 14 (~2 months after baseline)

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.

Diet

时间窗: Baseline

Nutrition Data System for Research (NDSR) 24-Hour Dietary Recall. Interviewer administered recall developed by the University of Minnesota Nutrition Coordinating Center (NCC).
