Official Journal of the American College of Sports Medicine 12,000-19,999 steps per day and 0.05), small variations in week-to-week PA did exist. Post-survey data indicated that 85.0% of participants believed that they benefited from the social media group and 80.0% would “absolutely” participate again in this, or a similar, program. CONCLusION: Although respondents were in strong support of the social media platform to deliver the program, participation rates were low and PA behavior was not impacted. Future studies should examine how to increase participation in social mediadelivered programs, and investigate the linkages between social media facilitation and PA behavior change. 1639 Board #231 May 30, 3:30 PM - 5:00 PM What Intensity of Physical activity should We Be Prescribing to Manage Weight-related health risk? Emily Knight, Melanie I. Stuckey, Robert J. Petrella, FACSM. Western University, London, ON, Canada. (No relationships reported) PurPOsE: Traditionally, physical activity (PA) interventions have focused on increasing the amount and intensity of activity and little attention has been given to reducing physical inactivity or modifying behavioural factors to engage in healthy lifestyles. The purpose of this study was to test the effectiveness of a home health monitoring study with tailored exercise prescription targeting changes in various intensities of PA (e.g. exercise, sedentary behaviour, or both). The program and baseline characteristics will be presented. METhOd: 61 older adults (55-75 years of age) participated in a 12-week health behaviour intervention involving personalized activity prescriptions tailored to baseline aerobic fitness using the Step Test and Exercise Prescription (STEP) tool. During enrolment, participants were randomized to either control or one of three intervention groups each targeting a specific intensity of PA: increasing high-intensity PA (i.e. exercise prescription); decreasing low-intensity PA (reducing sedentary behaviour prescription); or both (comprehensive PA prescription). At baseline, clinical measures for risk of cardiovascular disease were recorded, including blood pressure, fasting glucose, cholesterol, body mass index, waist circumference, and aerobic capacity. rEsuLTs: Data is presented as mean (+SD). The average age of the sample was 62.6 (+4) years, and the sample was 59% female. Body mass index was 31.4 (+5) kg/m2. Waist circumference was 101.6 cm (+13) for females, and 113.6 cm (+16) for males. Aerobic fitness was 25.96 ml/kg/min (+5.4) for females, and 32.76 ml/kg/min (+ 7.4) for males. No significant differences were found between groups for baseline clinic measures. CONCLusIONs: On average, our sample had undesirable anthropometric and aerobic fitness. This novel intervention aimed to explore the effect of prescribing various intensities of PA on changes in clinical risk for cardiovascular disease. Results from this study will help to inform future programs for activity prescription by health care professionals.

Ode 1 . 1 Saginaw Valley State University, University Center, MI. 2 Michigan State University, East Lansing, MI. (No relationships reported) Exercise is Medicine (EIM), a national initiative aimed at improving physical activity (PA) and health, is often promoted through the development of employee wellness programs. Evaluating changes in individuals who have consistently participated in wellness programs can demonstrate success and identify areas for improvement. PurPOsE: Therefore, the purpose was to evaluate changes in components of fitness, PA levels, perception of program components, and barriers to PA in employees who participated in a wellness program. METhOds: Participants included 44 employees enrolled in a wellness program, who had baseline and follow-up components of fitness and survey data within a single year. Physical assessments included anthropometrics with a calculation of body mass index, body composition, flexibility, muscular endurance, muscular strength, and an estimated aerobic capacity test. PA, perceptions, and barriers were all assessed via online survey. Descriptive data were reported as mean±SD. Repeated measures ANOVA was used to compare individual fitness assessment measures. Chi-square analyses and T-tests were used to assess gender differences. rEsuLTs: Mean age was 43±11 years at follow-up with 63% of participants being female. All component of fitness measures showed a trend for improvement at followup, with only push-ups (#1: 27±14; #2: 29±14) and estimated aerobic capacity (#1: 35±10 ml/kg/min, #2: 39±9 ml/kg/min) reaching statistical significance (p≤0.05). Additionally, a statistical difference in systolic blood pressure (#1: 129±15mmHg; #2: 123±11mmHg) was found in males. Aside from the electronic exercise log being beneficial to the participants’ overall wellness, no change was found in PA levels, barriers to PA, or perceptions of program components. CONCLusION: While neither PA levels nor the barriers to PA changed as a result of the wellness program, there were trends of improved component of fitness measures at follow-up. While not statistically significant, this improvement highlights the impact of the employee wellness program. Further, participants did not show a decline in health and fitness measures which implies stability throughout a year. Finally, data show that wellness program improvements should aim to increase PA levels and decrease barriers. 1641 Board #233 May 30, 3:30 PM - 5:00 PM The Virtual Trainer: Facilitating Physical activity and Fitness Improvement Through Internet and Mobile Phones Stanley Sai-chuen Hui, FACSM 1 , Ron Chi-wai Kwok 2 , Jacky Ka-wai Chan 1 , Emmanuel A. Hui 1 . 1 The Chinese University of Hong Kong, Shatin, Hong Kong. 2 The City University of Hong Kong, Kowloon Tong, Hong Kong. (No relationships reported) Health promotion websites have become popular means to motivate people to do more exercise. By applying various cyber-psychological theories and integrating smartphone technology, a free interactive website called “Virtual Trainer” (VT) was developed to help foster a physically active lifestyle. Given a participant’s self reported data, personal exercise prescriptions, online health and fitness evaluations, and text message reminders for adherence to the self-determined training schedule are some ways through which VT promoted exercise. PurPOsE: To evaluate the effectiveness of the VT program in increasing physical activity (PA) knowledge, practice, and health-related fitness. METhOds: Registered VT users (n=126; age=20.98 +/- 5.35 yrs.), who completed at least 8 weeks of online exercise training as well as online pre-post questionnaires on PA knowledge and practice, were extracted for analysis. Another 140 users completed the online pre-post health-related fitness assessments. The online questionnaire included 29 items on PA knowledge and PA participation measured by the International Physical Activity Questionnaire (IPAQ). For online health fitness assessment users were asked to follow online instructions and animations for self-administered fitness tests. Fitness items included a 3-min stepping test for aerobic fitness, sit-and-reach flexibility, cadence curl-up, push up, blood pressure and a stress inventory. rEsuLTs: Users demonstrated 37% increase in PA knowledge scores (from 16.5 to 22.6, p

Iowa State University, Ames, IA. (Sponsor: Panteleimon Ekkekakis, FACSM) (No relationships reported) The problem of physical inactivity and the epidemic of obesity among children around the world are well-documented. As several organizations have highlighted, efforts should be strengthened for the norm of physical inactivity to be reversed. Schools are often portrayed as having the potential to influence children’s physical activity (PA) levels. However, research on the motivation of stakeholders to integrate PA into daily school life is limited. PurPOsE: To examine the motivational profile and intentions of adult participants at a world-record activity break. METhOds: After the 2012 Just-A-Minute (JAM) World Record, 686 adults (90 M, 591 F; 293 PE teachers, 230 classroom teachers, 87 school admin and staff, 69 non-school related, 7 missing) anonymously completed an online survey about their motivation to participate (Situational Motivation Scale; Standage et al., 2003), their intention to use the JAM routines in the future and their intention to participate in a new record-breaking attempt next year. Ninety-four percent of the responders participated for others, the majority (76.1%) of whom was children under the age of 10. rEsuLTs: All participants reported high intrinsic motivation and low extrinsic motivation and amotivation for participation in the next JAM World Record. Groups were compared with one-way ANOVA on motivational factors and intention. Participants that had a role in schools were more intrinsically motivated (Identified regulation; F=9.15, p
