Golf for Veterans Study

Implementing a 12-week introductory golf intervention designed for older military veterans will allow us to evaluate the usefulness of golf as a means to promote physical activity and well-being across the lifespan. Golf, while studied from a performance perspective, has not been studied as an intervention to promote physical activity and health in older adults. This study will contribute to our knowledge about the feasibility and effectiveness of golf as a means to promote wellness across the lifespan. 1.0 OBJECTIVES AND PURPOSE OBJECTIVE 1: Quantify the changes in the functional, cognitive, and physiological abilities of older military veterans following a 12-week introductory golf intervention. Hypothesis: Participants will demonstrate improved functional, cognitive and physiological abilities following the intervention. OBJECTIVE 2: Quantify golf demands and performance including a biomechanical analysis of golf swings, putting and picking up a ball following a 12-week introductory golf intervention. Hypothesis: The demands of the golf intervention will be similar to or greater than the demands during commonly utilized older adult balance and strengthening exercises. OBJECTIVE 3: Evaluate the safety and feasibility of a 12-week introductory golf intervention. Hypothesis 3A: Adverse events associated with the intervention will be minor and not more frequent than AE's associated with other activity programs in seniors. Hypothesis 3B: Adherence to the program will greater than the adherence associated with other activity-intervention programs in seniors. 3.0 SELECTION AND WITHDRAWAL OF SUBJECTS Participants will be recruited using physician referrals, flyers, and visits to community centers, military Veteran fitness/wellness classes, military Veteran organizations, and military Veteran housing facilities in the Greater Los Angeles area. Once identified, the participants will go through a two-part screening process that includes a phone interview and clearance from their primary care physician. The phone screen includes the Telephone Memory Impairment Screen and a series of questions pertaining to the inclusion and exclusion criteria. Participants that pass the phone screen will be then required to receive clearance from their primary care physician prior to enrollment in the study. At the baseline testing session, additional details of the study will be explained to the participants, and consent obtained by an experienced researcher. 4.0 RISK ANALYSIS The functional assessments include activities that are regularly conducted throughout the day and have been utilized regularly as part of common clinical practice for assessing functional abilities. In more challenging activities, the participants will be appropriately spotted to ensure safety during the test. The potential risks are as follows: Functional Assessment: Fatigue (very minimal risk) - Rest will be provided as needed for the participants. Muscle soreness (minimal risk) - This is no greater than performing normal activities of daily living. Joint or muscle injury (minimal risk) - This is no greater than performing normal activities of daily living. Risk of falling (minimal risk) - On the more challenging tasks, participants will be spotted. Cognitive Assessment: Questionnaires (minimal risk) - Participants will be given the option to skip or stop answering any questions that make them uncomfortable. Golf Intervention: Joint or muscle injury (minimal risk) - The participants will be gradually introduced to the activities associated with the sport of golf. Each golf session will include a sport specific warm-up and exercises that prepare the participants for the daily activities. Additionally, the golfers will be supervised by a PGA Professional who specializes in instructing older adults. Fatigue (very minimal risk) - Participants will also be allowed rest as needed. Adverse Events: Any unanticipated problem will be recorded via an incident report. Protocols for the USC MBRL have been developed. Any serious adverse event will be reported to the Institutional Review Board at the USC Health Science Campus using the flow chart below. Continual Safety Monitoring: Researchers will have weekly meetings with the PGA instructors to keep informed about the intervention and participant safety. Additionally, each week, research associates will check in with participants according to the Problem Reports and Tracking Problems Protocol. 5.0 CLINICAL/LABORATORY EVALUATIONS AND STUDY CALENDAR Duration and Locations: The study from consent enrollment to final data collection will occur over a 16-week period. The study consists of two data collection visits to the Jacquelin Perry Musculoskeletal Biomechanics Research Laboratory (MBRL) in the Division of Biokinesiology and Physical Therapy located on the University of Southern California Health Science Campus and two data collection visits to a private room located at the West Los Angeles Veterans Administration Hospital (WLAVA). Day 1 (USC) and Day 2 (WLAVA) will occur following the consent enrollment (before training) and Day 3 (USC) and Day 4 (WLAVA) will occur following the completion of the training program. Biomechanical Analysis at USC (minimal risk): Laboratory kinematics and kinetics will be collecting using an 11-camera digital motion capture system (Qualysis, AB, Gothenberg, Sweden). 14 mm reflective markers will be used to define body segments and track motion during the trials. The trunk will be modeled as 2 rigid segments: pelvic and spine segments. The lower extremity will be modeled as 3 rigid segments: thigh, shank and foot. Day 1 Tasks (minimal risk): Data collection will last approximately 2 hours and will include previously validated functional assessments. Height, mass, resting heart rate, resting blood pressure and body fat percentage via Bioelectrical Impedance Analysis 6 minute walk test Hip muscle performance Gait analysis Modified Tandem Quiet Standing Balance confidence: Activities Specific Balance Confidence (ABC) Scale Participants will be given a Golf History Form to complete at home and return on Day 2 Day 2 Tasks (minimal risk): Data collection will last approximately 1.5 hours and will include previously validated cognitive and self-efficacy assessments as well functional measures. Participants will turn in their Golf History Form Self-reported health-related quality of life as assessed by the RAND 12-item Health Survey Surveys from the Midlife in the United States Survey (MIDUS) study assessing Positive and Negative affect, Social Well-Being, and Sense of Control Cognition as assessed by the NIH Toolbox for cognition Physical activity habits will be assessed via a questionnaire developed by the Postmenopausal Estrogen/Progestins Intervention (PEPI) Study and a physical activity free recall Episodic verbal learning and memory as assessed by the California Verbal Learning Test Senior Fitness Test: 30-second chair stand and 8-foot-up-and-go test Day 3 Tasks (minimal risk): Data collection will last approximately 3 hours and will include all tasks performed on Day 1 plus a biomechanical analysis of golf-related demands (see below). Golf swings, chips and putts that are common to recreational golf players. Participants will perform up to 5-10 trials of each swing type. Picking up and setting down a golf ball. Subjects will perform up to 5-10 trials of each strategy. Exit questionnaire about golf training program Day 4 Tasks (minimal risk): Data collection will last approximately 2 hours and will include all tasks performed on Day 2. Six months after the completion of the study, participants will receive a telephone call to follow-up on their current golf playing habits following the 12-week program. Golf Training Visits: Participants will participate in golf training programs at the Heroes Golf Course on the WLAVA campus. Participants will be divided into groups of 2-4 golfers and will meet with a PGA Professional two times per week for 12 weeks. Training sessions will last 1-2 hours. The program is specifically designed for older adults not currently playing golf. The first set of sessions will include introduction to the different forms of the golf swing beginning with partial swings and then gradually progressing to a full swing. Swing modifications will be provided on an individual basis to address needs of the participant. Golf play will begin on holes that are flatter and close to the clubhouse and will begin by only playing 1-2 holes. The golfers will then be appropriately progressed to longer golf play as the PGA Professional feels it is appropriate. All equipment and fees will be included and there will be no cost to the participants. Tasks (minimal risk): Warm-up: Each training session will begin with a sport specific warm-up that prepares the participants for the activities of the day. Supplementary Exercises: Additional strengthening and flexibility exercises will be included in training sessions to prepare the participants for golf-related activities. Golf swings and putting: These movements will be introduced in a progressive nature beginning with partial swings of the least forceful swing type and eventually progressing to the more forceful swings (drives). Swings with the following equipment will be included: putters, pitching or sand wedges, irons, and woods. Picking up a ball: The participants will be introduced to techniques to picking up a golf ball which will be individualized to the needs of the participants based off current research in the MBRL (HS-15-00038). Walking: Participants will gradually increase walking distance. Practice will begin on flat holes and will progress to holes with more challenging terrain. Golf play: Participants will be gradually introduced to regular golf play beginning with play on a single, low difficulty hole and progressing to multiple holes. Skill difficulty will also be gradually increased. During the intervention, walking distance will be tracked via fitness trackers. Golf performance will be tracked as well. 6.0 DATA COLLECTION AND MONITORING Data will be stored securely in the MBRL, CHP, room G9. Electronic data will be stored on a password protected computer. Hard copies of data will be stored in a locking file cabinet.
