Soccer Intervention in Prostate Cancer Survivors

Study Overview
=================
Brief Summary
-----------------
This study seeks to directly test the implementation feasibility of a soccer-based and lifestyle education intervention to determine the effects on bone health, body composition, mental health, functional and cardiometabolic status among prostate cancer survivors.

Detailed Description
-----------------
Prostate cancer (PCa) is the most common cancer in men in the U.S. and in other industrialized countries. The lifetime probability of PCa in males is one in nine, and it has a high economic burden, with costs expected to rise. Modern tailored treatment approaches, including androgen deprivation therapy (ADT), have resulted in longer life expectancy, but also longer treatment periods, which lead to significant adverse side effects. These often include decreased bone mineral density (BMD), increased risk of fractures, low functional capacity, loss of lean body mass (LBM), increased fat mass, insulin resistance, psychological distress and pain. Of particular concern is a sharp decline in bone health, with systemic bone loss caused by PCa-produced osteoclastogenic cytokines and drug interventions. Independent of disease stage, fractures in PCa patients are predictors of survival. In addition, concomitant physical inactivity and stress during and after treatment predispose PCa patients to elevated risk of deconditioning, BMD loss, cardiovascular and metabolic disease morbidity and mortality. Exercise-based lifestyle interventions aimed at counteracting treatment-induced adverse effects have been shown to be safe and effective in improving bone, functional and cardiometabolic health for patients with PCa. However, men, in general, are harder to engage in physical activity (PA) and lifestyle interventions. As an alternative to traditional exercise programs, recreational team sports provide a unique environment that may lead to increased physical activity participation and motivation to engage in other lifestyle changes. More than any other sport, recreational soccer (RS) has been shown to be a successful health intervention in patients with, or at risk of chronic diseases, including PCa. Leveraging the growing enthusiasm around soccer in Atlanta and the U.S. may lead to increased interest, participation, retention and engagement in lifestyle change programming among PCa survivors. Therefore, this study seeks to directly test the implementation feasibility of a soccer-based lifestyle change intervention to determine the effect on bone health, body composition, mental health, functional and cardiometabolic status among PCa survivors. Participants will be offered an intensive intervention including RS programming and lifestyle education. The group will receive RS, consisting of conditioning drills and games, adapted to the population during 60-minute sessions twice per week. The researchers will evaluate health outcomes at baseline and after 3 months of the intervention.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Lumbar Spine Bone Mineral Density (BMD) | Bone mineral density will be measured by dual x-ray absorptiometry (DXA) scan at the lumbar spine (L2-L4). Decreased BMD a is associated with an increased risk of fractures. | Baseline, 3 months post-intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Hip BMD | Bone mineral density will be measured by dual x-ray absorptiometry (DXA) scan at the hip. Decreased BMD a is associated with an increased risk of fractures. | Baseline, 3 months post-intervention | 
| Osteocalcin Level | Osteocalcin is marker of bone formation. The normal range for osteocalcin varies by lab and elevated levels are seen in patients with bone diseases characterized by increased bone turnover. | Baseline, 3 months post-intervention | 
| C-terminal Telopeptide of Collagen (CTx) | C-terminal telopeptide of collagen (CTx) is a bone resorption marker. Increased levels indicate increased bone resorption with conditions such as osteoporosis and osteopenia. | Baseline, 3 months post-intervention | 
| Weight | Weight is measured in kilograms (kg). | Baseline, 3 months post-intervention | 
| Body Mass Index (BMI) | Body Mass Index (BMI) is weight in kilograms divided by the square of height in meters. | Baseline, 3 months post-intervention | 
| Percentage of Body Fat | Body fat is measured by dual x-ray absorptiometry (DXA) scan. | Baseline, 3 months post-intervention | 
| Waist Circumference | Waist circumference is measured in centimeters (cm). | Baseline, 3 months post-intervention | 
| Lean Body Mass | Lean body mass is body weight minus weight from body fat. | Baseline, 3 months post-intervention | 
| Resting Heart Rate | The normal resting heart rate in adults is between 60 and 100 beats per minute (bpm). A lower resting heart rate indicates that the person has better fitness as the heart is working more efficiently. | Baseline, 3 months post-intervention | 
| Systolic Blood Pressure | Systolic blood pressure (BP) will be measured while sitting using a calibrated electronic blood pressure sphygmomanometer at Baseline and at 3 months post-intervention. A normal systolic blood pressure reading is lower than 120 mmHg. BP values higher than 120 mmHg correlate with worse outcome. | Baseline, 3 months post-intervention | 
| Diastolic Blood Pressure | Diastolic blood pressure (BP) will be measured while sitting using a calibrated electronic blood pressure sphygmomanometer prior to any activity (Baseline) and at 3 months post-intervention. A normal diastolic blood pressure reading is lower than 80 mmHg. BP values higher than 80 mmHg correlate with worse outcome. | Baseline, 3 months post-intervention | 
| Aerobic Capacity | Aerobic capacity is measured by 6 minute walk test distance (meters). | Baseline, 3 months post-intervention | 
| Muscle Strength | Muscle strength is measured as hand grip strength (kg). Hand grip was measured using a study approved dynamometer to test the maximum isometric strength of the hand and forearm muscles of the dominant hand. An increase in values means that grip strength is improving. | Baseline, 3 months post-intervention | 
| Behavioral Regulation in Exercise Questionnaire-2 (BREQ-2) Score | Physical activity self-efficacy is assessed with the BREQ-2 instrument. The BREQ-2 has 19 items measuring motivation to exercise, with 5 motivational styles examined: intrinsic regulation (the respondent finds physical activity enjoyable), identified regulation (the respondent sees benefits of physical activity), introjected regulation (physical activity is done to increase self-esteem or avoid negative feelings with not performing exercise), external regulation (physical activity is done based on rewards or punishments from someone else), and amotivation (the respondent has no motivation to engage in physical activity). Responses are given on a 5 point Likert scale where 0=not true for me, and 4=very true for me. A relative autonomy index (RAI) can be calculated by weighting the scores for each motivational style factor. The weights range from 3 to -3 and total RAI scores range from -24 to 20. Higher scores indicate greater self-determined motivation to engage in physical activity. | Baseline, 3 months post-intervention | 
| Dietary Intake | The dietary intake is measured using the Nutrition Database System for Research (NDSR) 24-hour dietary recall. The NDSR is a dietary analysis software application used to collect and calculate nutritional intake. | Baseline, 3 months post-intervention | 
| Number of Participants Smoking Cigarettes | Smoking habits are assessed with the National Health and Nutrition Examination Survey (NHANES) 2019-2020 for smoking and tobacco use. This instrument includes 24 items and the number of questions that a respondent answers depends on their past and current smoking behaviors. Participants are asked if they currently smoke cigarettes and possible responses are: every day, some days, and not at all. | Baseline, 3 months post-intervention | 
| Alcohol Habits | Number of alcohol beverages per week will be recorded. | Baseline, 3 months post-intervention | 
| Sleep Time | Average sleep time will be collected in minutes per day. | Baseline, 3 months post-intervention | 
| Weekly Steps | Participants will be asked to wear a Garmin fitness tracker throughout the study and physical activity will be measured as steps taken per week. | Baseline, 3 months post-intervention | 
| SF-12 Health Survey Score | Quality of life is assessed with the SF-12 Health Survey. The SF-12 is a multipurpose, standardized self-report short form survey with 12 questions assessing mental and physical functioning. The SF-12 consists of 12 items with a Likert-type response format that measures quality of life with a Physical Component Summary (PCS) and Mental Component Summary (MCS). Subscales associated with the PCS include physical functioning, role limitations due to physical problems, bodily pain, and general health perceptions. Subscales associated with the MCS include vitality (energy and fatigue), social functioning, role limitations due to emotional problems, and mental health. A scoring algorithm is used to generate a total score for each component ranging from 0 to 100. Low values represent a poor health state while high values represent a good health state. | Baseline, 3 months post-intervention | 
| Center for Epidemiologic Studies Depression Scale (CESD) Score | Symptoms of depression are assessed with the CESD. The CESD is a 20-item questionnaire asking about feelings and behaviors during the past week. Responses are given on a 4-point scale where 0 = rarely or none of the time (less than 1 day), 1 = some or a little of the time (1-2 days), 2 = occasionally or a moderate amount of time (3-4 days), and 3 = most or all of the time (5-7 days). Scores range from 0 to 60 with high scores indicating greater depressive symptoms. | Baseline, 3 months post-intervention |
