Neurological impairments are a major contributor to problems of gait and balance in older people. Whether due to well-characterized conditions such as stroke or Parkinson's disease, or to more recently recognized conditions such as leukoencephalopathy or age related dopamine deficiency, there are numerous emerging opportunities to promote improved function through physical activity. The key to successful interventions may be to go beyond traditional exercise that focuses on endurance and strength, to exercise that incorporates principles of motor leaming. NEW TECHNOLOGIES TO ENGAGE OLDER ADULTS IN PHYSICAL ACTIVITY Smith, Stuart Neuroscience Research Australia, Australia. Over the past few decades, there has been a wealth of published scientific evidence for the physical, cognitive, and social health-related benefits of exercise and increasing physical activity (PA), especially in older adults. Strength, mobility, aerobic capacity, energy, anxiety, depression, and reduction in fall risk in older populations have been shown to improve fol- lowing increased PA interventions. While numerous studies have demonstrated the health- related benefits of PA, adherence to PA programs is often disappointing. Barriers to adherence may include lack of interest in the program, low outcomes expectation, the weather, or even a fear of falling during exercise. In our group at Neuroscience Research Australia, we are examining how videogame technology can be used to increase compliance with exercise. In particular we are assessing the effects of exercise-based videogames to reduce the risk of falling, a major barrier to continued independence. S202 Thursday 16th August S203 Symposia NEW INSIGHTS INTO PREVENTION OF DISABILITY BY PHYSICAL ACTIV- ITY AND EXERCISE Tak, Erwin'; Dronkers, Jaap^; Koeneman, Margot'; Hopman-Rock, Marijke" 'TNO, Netherlands; 'General Hospital Gelderse Vallei, Netherlands; ^TNO/VU University Medical Center, Netherlands; ''TNO/VUmc, Netherlands. Aging is offen accompanied by a decline in functional performance and disability as described in the disablement process model (Nagi, 1976; Verbrugge & Jette, 1994). Physical activity and exercise have been identified to influence the pathway from aging and disease to dis- ability. Recent work in this area will be presented by researchers from the Body ©Work Research center TNO VU university medical center (Leiden/Amsterdam, The Netherlands). This symposia will cover a short introduction, a review and meta-analysis of the relation- ship between physical activity and ADL disability in older adults, studies on preoperative physical activity and physical fitness predicting postoperative recovery, and whether major life events predict physical activity among older adults. Review and meta-analysis of the relationship between physical activity and ADL dis- ahility in older adults Tak, Erwin''; Kuiper, Rebecca'; Chorus, Astrid'; Hopman-Rock, ''Expertise Center Lifestyle, TNO, Leiden, Netherlands; 'Body® Work research center TNO/ VU university medical center, TNO/VUmc, Leiden/Amsterdam, Netherlands. Introduction: physical activity (PA) has been identified as an important behavior to prevent or slow down the disablement process caused by aging an chronic diseases. It is unclear whether PA can directly prevent or reduce ADL disability. We performed a systematically review and meta-analysis on the association between physical activity and the incictence and progression of disability in basic activities of daily living (BADL) in community dwelling older adults. Methods: electronic literature search in PubMed (until January 2012) and by cross-referencing; prospective longitudinal studies in community dwelling older adults (50+) with PA and BADL included at baseline and follow-up using multivariate analysis and reporting a point estimate for the association were included. Two reviewers independently scored all included articles on quality measure, study description, PA level (low, medium, high) and disability definition (incidence or progression), point estimates (Odds or risk ratio). Results: compared to low PA, a medium/high PA level reduces the risk on incident BADL with 0.51 (95%CI: 0.38, 0.68; p < .001) based on 9 included longitudinal studies covering over 17.000 participants followed 3 to 10 years. This result was not different for older (75+) or younger age groups, length of follow-up, study quality or for differences in demc^raphics, health status, functional limitations, or lifestyle. The risk of progression of BADL for older adults with medium/high PA compared to low PA is 0.55 (95%CI: 0.42, 0.71; p < .001), based on 4 studies covering around 8.500 participants. Discussion: PA prevents and slows down the disablement process in aging or diseased populations, positioning PA promotion as a very effective strategy in preventing and reducing disability, and therefore enhancing future independence and reducing health care costs in aging societies. S204 World Congress Abstracts The better the way in, the better the way out: Preoperative functional status as predic- tor and improvement factor of the postoperative course Dronkers JJ'; Chorus AMJ^, van Meeteren NLU'•*, Hopman-Rock y9-^-^ 'Gelderse Vallei Hospital, Ede, the Netherlands; ^HU University of Applied Sciences, Utrecht, the Netherlands; ^the Netherlands Organisation for Applied Scientific Research, Leiden, the Netherlands; ''the Netherlands and Center for Care Technology Research, Maastricht, the Netherlands; 'Body@Work, Research Center on Physical Activity, Work and Health, Amsterdam, the Netherlands; ^VU University Medical Center, Amsterdam, the Netherlands. Objective: To determine whether preoperative physical activity (PA) and physical fitness (PF) can predict postoperative recovery in older patients. Background: A low PA and PF adversely affect how a patient responds, physically and mentally, to the challenge of hospi- talization and surgery, which could result in increased mortality, postoperative complications, and loss of mobility. Methods: Prospective cohort study of 175 patients (mean age 72±7 years) scheduled for major oncological abdominal surgery. Conventional dsk factors (age, metastatic cancer, diabetes, heart diseases, COPD, smoking, productive cough), PA factors (LASA Physical Activity Questionnaire [LAPAQ]), and PF factors (Timed Up and Go [TUG], Chair Rise Time [CRT], Maximal Inspiratory Pressure [MIP], Respiratory Cumulative Energy [RCE], Handgrip Strength [HGS]) were assessed preoperatively and in-hospital mortality, discharge destination, and length of stay [LOS]) postoperatively. Results: Thirteen patients died in hospital, and in-hospital mortality was significantly correlated with age, LAPAQ, TUG, RCE, and HGS (p < 0.05); multivadate analysis identified LAPAQ (OR 5.5, 95%CI 1.4-21.9) and RCE (OR 5.2,95%CI 1.4 -19.1) as independent predictors. Sixteen patients were discharged to a nursing home, and this was correlated with age and all but one PA and PF factor (p < 0.05); multivariate analysis identified LAPAQ (OR 6.7, 95%CI 1.4 - 3.0) as independent predictor. LOS (median 12; IQR 12 days) was significantly correlated with diabetes, COPD, CRT, and MIP (p < 0.05); multivadate analysis identified COPD (B 0.5, 95%CI 0.2 - 0.9) and LAPAQ (B 0.3, 95%CI 0.1 - 0.5) as independent predictors. Conclusion: Preoperative indices of PA and PF were prognostic of postoperative recovery, additional to conventional predictors. Do major life events influence physical activity among older adults: The Longitudinal Aging Study Amsterdam Koeneman MA'-^, Chinapaw MJM'-^, Verheijden MW'', van Tilburg TG", Visser M'-*, Deeg DJH«, Hopman-Rock M'2' 'Body@Work, Research Center for Physical Activity, Work and Health, TNO-VU Univer- sity Medical Center, The Netherlands; ^Department of Public and Occupational Health and EMGO Institute for Health and Care Research, VU University Medical Center, The Netherlands; ^TNO, Leiden, The Netherlands; ''Department of Sociology, VU University Amsterdam, the Netherlands; ^Department of Health Sciences, VU University Amsterdam, the Netherlands; ^Department of Epidemiology and Biostatistics and EMGO Institute for Health and Care Research, VU University Medical Center, The Netherlands. Background: Major life events are associated with a change in daily routine and could thus also affect habitual levels of physical activity. Major life events remain largely unexplored as determinants of older adults' participation in physical activity and sports. This study focused on two major life events, widowhood and retirement, and asked whether these major life events were associated with leisure time moderate to vigorous physical activity (MVPA) and Thursday 16th August S205 sports participation. Methods: Data from the first (1992-93) and second (1995-96) wave of the Longitudinal Aging Study Amsterdam (LASA), a prospective cohort study with a rep- resentative sample of the Dutch population aged 55 and older, were used. Change in marital status and employment status between baseline and follow-up was assessed by self-report. Time spent in MVPA (min/d) and sports participation (yes/no) was calculated based on the LASA Physical Activity Questionnaire.
