Background As formula diets have demonstrated to be effective in reducing weight, we hypothesised that in patients with overweight or obesity and accompanied cardiovascular risk factors, combining a liquid formula diet with a lifestyle intervention is superior in reducing weight and improving cardiovascular risk factors than lifestyle intervention alone. Methods In this multicenter RCT 463 participants with overweight or obesity (BMI: 27-35 kg/m²; at least one additional co-morbidity of the metabolic syndrome) were randomised (1:2) into either a control group with lifestyle intervention only (CON, n = 155) or a lifestyle intervention group including a liquid meal replacement (INT, n = 308). Both groups used telemonitoring devices (scales and pedometers), received information on healthy diet and were instructed to increase physical activity. Telemonitoring devices automatically transferred data into a personalised online portal and acquired data were discussed. INT obtained a liquid meal replacement substituting three meals/day (~1200 kcal) within the first week. During weeks 2-4, participants replaced two meals/day and during weeks 5-26 only one meal/day was substituted (1300-1500 kcal/day). Follow-up was conducted after 52 weeks. Intention-to-treat analyses were performed. Primary outcome was weight change. Secondary outcomes comprised changes in cardiometabolic risk factors including body composition and laboratory parameters. Results From the starting cohort 360 (78%, INT: n = 244; CON: n = 116) and 317 (68%, INT: n = 216; CON: n = 101) participants completed the 26-weeks intervention phase and the 52-weeks follow-up. The estimated treatment difference (ETD) between both groups was -3.2 kg [-4.0; -2.5] (P < 0.001) after 12 weeks and -1.8 kg [-2.8; -0.8] (P < 0.001) after 52 weeks. Conclusions A low-intensity lifestyle intervention combined with a liquid meal replacement is superior regarding weight reduction and improvement of cardiovascular risk factors than lifestyle intervention alone., Author(s): Martin Halle [sup.1] [sup.2] , Martin Röhling [sup.3] , Winfried Banzer [sup.4] , Klaus Michael Braumann [sup.5] , Kerstin Kempf [sup.3] , David McCarthy [sup.6] , Nina Schaller [sup.1] [...]

Introduction: High exercise adherence is a key factor for effective exercise programmes. However, little is known about predictors of exercise adherence to a multimodal machine‐based training in older retirement home residents. Aims: To assess exercise adherence and potential predictors of adherence. Furthermore, to evaluate user acceptance of the multimodal training and the change in exercise self‐efficacy. Methods: In this sub‐analysis of the bestform‐F study, a total of 77 retirement home residents ≥65 years (mean age: 85.6 ± 6.6 years, 77.9% female) participated in a 6‐month machine‐based resistance, coordination and endurance training. Attendance to the training was documented for each training session. To identify potential predictors a multiple linear regression model was fitted to the data. Analyzed predictors included age, sex, body mass index (BMI), physical function, exercise self‐efficacy, and physical activity history. Different domains of user acceptance (e.g. safety aspects, infrastructure) and exercise self‐efficacy were assessed by a questionnaire and the exercise self‐efficacy scale (ESES), respectively. Results: Mean exercise adherence was 67.2% (median: 74.4%). The regression model (R2 = 0.225, p = 0.033) revealed that the 6‐minute walk test (6‐MWT) at baseline significantly predicted exercise adherence (β: 0.074, 95% confidence interval (CI): 0.006–0.142, p = 0.033). Different user domains were rated at least as good by 83.9%–96.9% of participants, reflecting high acceptance. No statistically significant change was found for exercise self‐efficacy over 6 months (mean change: 0.47 ± 3.08 points, p = 0.156). Conclusion: Retirement home residents attended more than two thirds of offered training sessions and physical function at baseline was the key factor for predicting adherence. User acceptance of the training devices was highly rated. These findings indicate good potential for implementation of the exercise programme. [ABSTRACT FROM AUTHOR]

- Abstract
Lifestyle interventions including meal replacement are suitable for prevention and treatment of obesity and type-2-diabetes. Since leptin is involved in weight regulation, we hypothesised that a meal replacement-based lifestyle intervention would reduce leptin levels more effectively than lifestyle intervention alone. In the international, multicentre, randomised-controlled ACOORH-trial (Almased-Concept-against-Overweight-and-Obesity-and-Related- Health-Risk), overweight or obese participants with metabolic syndrome criteria (n = 463) were randomised into two groups and received telemonitoring devices and nutritional advice. The intervention group additionally used a protein-rich, low-glycaemic meal replacement. Data were collected at baseline, after 1, 3, 6, and 12 months. All datasets providing leptin data (n = 427) were included in this predefined subanalysis. Serum leptin levels significantly correlated with sex, body mass index, weight, and fat mass at baseline (p < 0.0001). Stronger leptin reduction has been observed in the intervention compared to the control group with the lowest levels after 1 month of intervention (estimated treatment difference −3.4 µg/L [1.4; 5.4] for females; −2.2 µg/L [1.2; 3.3] for males; p < 0.001 each) and was predictive for stronger reduction of body weight and fat mass (p < 0.001 each) over 12 months. Strongest weight loss was observed after 6 months (−5.9 ± 5.1 kg in females of the intervention group vs. −2.9 ± 4.9 kg in the control group (p < 0.0001); −6.8 ± 5.3 kg vs. −4.1 ± 4.4 kg (p = 0.003) in males) and in those participants with combined leptin and insulin decrease. A meal replacement-based lifestyle intervention effectively reduces leptin which is predictive for long-term weight loss.

- Abstract
While obesity impairs health-related quality of life (HRQOL), lifestyle interventions targeting weight reduction have been effective in improving HRQOL. Therefore, we hypothesised that a meal replacement-based lifestyle intervention, which has been shown to successfully reduce weight, would also improve HRQOL more effectively than a lifestyle intervention alone. In the international, multicenter, randomised-controlled ACOORH-trial (Almased-Concept-against- Overweight-and-Obesity-and-Related-Health-Risk), overweight or obese participants with elevated risk for metabolic syndrome (n = 463) were randomised into two groups. Both groups received telemonitoring devices and nutritional advice. The intervention group additionally used a protein-rich, low-glycaemic meal replacement for 6 months. HRQOL was estimated at baseline, after 3 and 12 months, using the SF-36 questionnaire, and all datasets providing HRQOL data (n = 263) were included in this predefined subanalysis. Stronger improvements in the physical component summary (PCS) were observed in the intervention compared to the control group, peaking after 3 months (estimated treatment difference 2.7 [1.2; 4.2]; p < 0.0001), but also in the long-term. Multiple regression analysis demonstrated that insulin levels and the achieved weight loss were associated with the mental component summary (MCS) after 12 months (p < 0.05). Thus, meal replacement-based lifestyle intervention is not only effective in weight reduction but, concomitantly, in enhancing HRQOL. [ABSTRACT FROM AUTHOR]

Abstract Background Adequate physical activity (PA) is considered as a key factor in the fight against the obesity epidemic. Therefore, detailed description of the actual PA and its components in the population is necessary. Additionally, this study aims to investigate the association between PA and obesity risk in a representative population sample in Bavaria, Germany. Methods Data from 893 participants (age 13–80 years) of the Bavarian Food Consumption Survey II (BVS II) were used. In each participant, three computer-based 24-hour recalls were conducted by telephone assessing type and duration of PA in the domains occupation, sports, other strenuous leisure time activities (of mostly moderate intensity) as well as TV/PC use in leisure time and duration of sleeping. After assigning metabolic equivalents (METs) to each activity, estimates of energy expenditure (MET*h) and total daily PA level (PALest.) were calculated. In a subgroup of adults (n = 568) with anthropometric measurements logistic regression models were used to quantify the impact of PA on obesity risk. Results Estimated average PA in women and men was 38.5 ± 5.0 and 40.6 ± 9.3 MET*h/d, respectively, corresponding to PALest. values of 1.66 ± 0.22 and 1.75 ± 0.40. Obese subjects showed lower energy expenditure in the categories sports, occupation, and sleeping, while the time spent with TV/PC during leisure time was highest. This is confirmed in logistic regression analyses revealing a statistically significant association between obesity and TV/PC use during leisure time, while sports activity was inversely related to obesity risk. Overall, less than 1/3 of the study participants reached the recommended PAL of ≥ 1.75. Subjects within the recommended range of PA had an about 60 % (odds ratio = 0.43; 95% CI: 0.21–0.85) reduced risk of obesity as compared to inactive subjects with a PALest. Conclusion Based on the results of short-term PA patterns, a major part of the Bavarian adult population does not reach the recommendations (PAL>1.75; moderate PA of > 30 min/d). Despite the limitations of the study design, the existing associations between sports activity, TV/PC use and obesity risk in this population give further support to the recommendation of increasing sports activity and reducing sedentary behaviour in order to prevent rising rates of obesity.

570 Life sciences - Abstract
As the fastest long-endurance runner, the bipedal ostrich (Struthio camelus) was selected as a prime model organism to investigate the physical attributes underlying this advanced locomotor performance. A specific integrative approach combining morphological, morphometric, kinematic and pedobarographic methods was developed. The comparative morphometric analysis of the hind limbs of all ratite species revealed that leg segment ratios in the ostrich are the most specialised for efficient locomotion, especially when taking into consideration its unique supra-jointed toe posture. In addition, the crural muscle mass is more concentrated towards the hip joint in the ostrich than in its ratite relatives. According to the Law of the Pendulum, this concentration of mass towards the pivot point – in concert with the relatively longest and lightest distal leg elements – represents a mechanical optimisation of limb swinging capacities. While musculature clearly drives limb movement, the passive guidance and constraint of motion range by ligamentous structures combined with joint surface contours allows a high level of energy output efficiency during all stages of locomotion and ensures articular stability during slow locomotion as well as high-speed performance. So far, the influence of these passive effects in locomotion has been largely ignored. In order to quantify the guiding effect of these anatomical structures, kinematic data of adult ostriches during walking and running were collected. Subsequently, these data were compared with results from manual manipulation experiments performed with the limbs of anatomical specimens – both fully intact and with muscles removed – leaving only the ligament system intact. This investigation revealed that the range of motion among leg segments was nearly identical in all sample groups, especially in regard to maximum extension values. This indicates that ostrich hind limb dynamics are managed to a significant degree by passive elements that ensure a controlled swing-plane with minimal deviation from an optimal attitude. Further dissections allowed some of these features to be described in detail, with an emphasis on functional-morphological examination of the intertarsal joint. The intertarsal joint contains a significant locking mechanism, briefly mentioned in historical documents, but described and functionally analysed herein for the first time. The functional examination qualified the interplay of three collateral ligaments, the tendinous M. fibularis brevis and specific joint surface protrusions as the basis for this effect which remains absent in smaller ground-dwelling bird species. A proximate quantification, based on comparative morphological and kinematic data, revealed function of Struthio's passively locked intertarsal joint as a potent stabiliser in the supporting limb during the ground-contact phase of locomotion. During stance phase, it is crucial that the supporting limb is stabilised internally and in relation to the substrate. As yet, no study exists concerning use and loading of the actual ground contact elements. The toes must absorb body mass, guarantee stable grip and provide energetic push off. Obvious specialisations of the ostrich's phalangeal complex include toe reduction (leaving only 3rd and 4th toe), claw reduction (only at 3rd toe) and a permanently elevated metatarsophalangeal joint. Using a relatively new methodology to examine in vivo toe function, pedobarography was employed on specifically trained ostriches to allow extensive collection of Centre of Pressure (CoP) and load distribution (LD) data. In contrast to a relatively predictable CoP trajectory at all speeds, conspicuous LD differences were observed between slow and fast trials. Load was distributed rather inconsistently during walking, while a typical tripod-like toe-print occurred in all running trials to presumably deliver additional stability during the comparatively short stance phase. Significant grip is provided by the highly directed impact of the 3rd toe claw-tip, suggesting its important function as a positional anchor during running. Pedobarographic analysis further showed the importance of the 4th toe as an outrigger to maintain balance, rendering a future reduction highly unlikely. In conclusion, the application of interdisciplinary methodologies allowed comprehensive data collection and integration of the model organism within its ecological context. The data gained from this thesis increases the current knowledge about ostrich locomotion by identifying distinct structural attributes as essential elements for extreme cursorial performance. The present data may alter existing models for calculation of the metabolic cost of terrestrial locomotion and aid in the reconstruction of theropod locomotion, as these branch sciences often overlook the important role of ligaments and passively-coupled motion cycles in reducing the cost of locomotion.
