Exercise to Enhance Cardiovascular Health Among Black Prostate Cancer Patients With Androgen Deprivation Therapy

Framingham Risk Score, an established comprehensive tool for evaluating the risk of developing cardiovascular disease using blood samples (i.e., low-density lipoprotein-cholesterol [LDL-C] or total cholesterol [TC], high-density lipoprotein-cholesterol [HDL-C]), demographic and medical profiles , and lifestyle behaviors (i.e., age, blood pressure, and diabetic and smoking status). The score ranges from -4 to 36 and the 10-year cardiovascular risk will be calculated accordingly (a higher score indicates a higher risk of cardiovascular disease).

Cardiorespiratory fitness will be assessed as VO2peak by a graded maximal cycle exercise stress test. VO2peak is defined as the highest values of oxygen uptake averaged among every 15-second interval during the test. VO2peak will be reported in both relative (ml·kg-1·min-1) and absolute (L/min) terms

Muscular strength will be measured as 1-repetition maximum (RM) (i.e., the greatest resistance that can be moved through the full range of motion), which has been the standard for strength assessments. 1-RM values will be estimated from 10-RM using validated equations on 12 exercises including the ten exercises utilized in the prescription not performed on machines.

Physical function will be assessed by the SPPB. This includes the following 3 lower extremity measures completed in the following order. Timed balance (seconds): Balance will be assessed under 3 conditions (side-by-side, semi-tandem, and tandem stands). Gait speed (seconds): Gait speed will be assessed over a 4-meter flat surface distance. The participant will be asked to complete 2 attempts of this test. Time will be recorded using an electronic timing system. Chair stand (seconds): Chair stand will be performed under 2 conditions: a) subjects will perform a single chair stand; b) subjects will be asked to perform 5 repeated chair stands as quickly as possible; time to completion will be recorded.

Mobility will be assessed using the Timed Up and Go (TUG) test, which has been shown to predict immediate fall risk better than static balance tests or isometric muscle strength. Participants begin seated in a chair with hands on the armrests, are asked to rise, walk to a line on the floor 3 m from the chair, turn around, and return to the same seated position as quickly and safe as possible. Scores will be taken as the time (seconds) to complete the task, with one practice trial given. An average of time for 3 trials is calculated.

Grip strength will be measured using a hand-held dynamometer on the participant's dominant hand. The subject will be asked to grip the handle of the dynamometer with one hand using as much grip pressure (kg) as possible while holding for 2 seconds. The subject will be asked to complete 2 grip strength attempts.

Fat mass (kg) will be obtained from a whole-body dual-energy x-ray absorptiometry scan (DXA; Lunar DPX-IQ), which provides highly accurate results compared to computed tomography, a gold standard measure of body composition.

Percent body fat will be obtained from a whole-body dual-energy x-ray absorptiometry scan (DXA; Lunar DPX-IQ), which provides highly accurate results compared to computed tomography, a gold standard measure of body composition.

Lean mass (kg) will be obtained from a whole-body dual-energy x-ray absorptiometry scan (DXA; Lunar DPX-IQ), which provides highly accurate results compared to computed tomography, a gold standard measure of body composition.

A constant-tension tape measure will be used to obtain waist circumference (i.e., the distance around the waist using the umbilicus as the reference point) (cm).

A constant-tension tape measure will be used to obtain hip circumference (the distance around the widest girth of the buttocks using the greater trochanter as a landmark) (cm).

European Organization for Research and Treatment of Cancer- Quality of Life Questionnaire-C30 will assess health-related quality of life, consisting of substacles including functional scales (physical, role, cognitive, emotional, social), symptom scales (fatigue, pain, and nausea and vomiting), global health status and quality of life scale, also several single-item symptom measures. The score ranges from 0 to 100 and a higher value indicates a better quality of life.

Expanded Prostate Cancer Index Composite-26 will assess prostate cancer-specific symptoms (e.g., urinary incontinence, sexual dysfunction, and bowel dysfunction). The score ranges from 0 to 100 and a higher value indicates a worse symptom.

MD Anderson Symptom Inventory will assess cancer treatment symptoms (e.g., pain, neuropathy). The score ranges from 0 to 10 and a higher value indicates a worse symptom.

The Rosenberg Self-Esteem Scale will assess self-esteem. The score ranges from 10 to 40 and a higher value indicates a better self-esteem.

The Acceptability of Intervention Measure, Intervention Appropriateness Measure, and Feasibility of Intervention Measure will be assessed at post-intervention to measure participant-perceived intervention feasibility and acceptability. Each measure has four items with 5-point likers scale. The values in each measure will be the mean of four items and range from 5-20. A higher value means a more acceptable, appropriate, and feasible intervention, perceived by participants, respectively.
