Abstract
Increasing physical activity and reduction of sedentary behaviour play important roles in health promotion and prevention of lifestyle-related diseases in children and adolescents. However, the question of how much physical activity is useful for which target group is still a matter of debate. International guidelines (World Health Organization; European Association for the Study of Obesity), which are mainly based on expert opinions, recommend 60 min of physical activity every day. Age- and sex-specific features and regional differences are not taken into account. Therefore, expert consensus recommendations for promoting physical activity of children and adolescents in Germany were developed with special respect to national data, but also with respect to aspects of specific target groups, e.g., children with a lower socio-economic status (SES) or with migration background. They propose 90 min/day of physical activity, or at least 12,000 steps daily. Additionally, lifestyle factors, especially restriction of media consumption, were integrated. The recommendations provide orientation for parents and caregivers, for institutions such as schools and kindergartens as well as for communities and stakeholders.

Abstract
Purpose: To analyse time domain, spectral and fractal properties of speed regulation during half-marathon racing. Methods: In twenty-one male experienced runners high-resolution data on speed (V), stride frequency (SF) and stride length (SL) were assessed during half-marathon competition (21098 m). Performance times, time and frequency domain variability, spectral scaling exponent (beta) and fractal dimension (FD) of V, SF and SL were analysed. Results: V of 3.65±0.41 m·s-1, SF of 1.41±0.05 Hz and SL of 2.58±0.25 m occurred with higher (p<0.05) individual variability in V and SL compared to SF. Beta and FD were always in between 1.04 and 1.88 and 1.56 to 1.99, respectively. Beta and FD differed (p<0.05) in SF and SL compared to V and were correlated in V and SL (r=0.91, p<0.05). Spectral peaks of V, SF and SL occurred at wavelengths in between 3 to 35 min, and those of V and SL were interrelated (r=0.56, p<0.05). Mean SF and mean SL were significantly correlated with performance (r=0.59 and r=0.95, p<0.05). SL accounted for 84±6 % and SF for 16±6 % of speed variability, respectively. Conclusions: The observed non-random fluctuations in V, SF and SL correspond to non-stationary fractional Brownian motion with inherent long-range correlations. This indicates a similar complex regulation process in experienced runners that is primarily mediated via SL.

Abstract
BACKGROUND The model for integrated care (IC) of those seriously mentally ill patients insured with the DAK-Gesundheit health insurance and various Betriebskrankenkassen (members of the VAG Mitte) from the regions Berlin, Brandenburg, Lower Saxony and Bremen allows a complex treatment in the outpatient setting which consists of psychiatrists, general practitioners and clinicians, psychiatric nursing, sociotherapy (only in Berlin), internal medicine quality circles, orientation on treatment guidelines and conceptual consensus with the relevant care clinics. The aim of the evaluation is to illustrate the health economic effects of IC. METHODS In the period from 2006 to 2010 insured members of the DAK-Gesundheit and other involved health insurance companies with a serious mental illness, a significant impairment of social functioning and the need to be treated to avoid or substitute an in-hospital stay were included in the integrated care. The cost perspective was that of the statutory health insurance companies. For the health economic evaluation, the utilisation of continuous IC over 18 months was compared to the last 18 months prior to the inclusion in IC. The clinical findings were gathered quarterly during the IC using CGI (Clinical Global Impressions) and GAF (Global Assessment of Functioning Scale). RESULTS A total of 1 364 patients receiving IC in 66 doctor's practices were documented (of those, 286 had diagnoses of ICD-10 F2, 724 ICD-10 F32-F39). The median age was 48.8 years, 69% were female. 24% had their own source of income, 40% were on the pension, and the rest of the patients were receiving transfer benefits in some form. In 54% of the cases IC was used to avoid an in-hospital stay, in 46% of the cases to substitute an in-hospital stay. The degree of the CGI was 5.5 on average at the time of inclusion and the GAF score was 36.5 on average. The 226 patients with continuous documentation over 18 months were included in the health economic analysis. The number of days spent in hospital was lower during the IC period as compared to the 18 months prior to IV (11.8 vs. 28.6 days, p<0.001), the inpatient costs were lower (5 929 ± 13 837 Euro vs. 2 458 ± 6 940 Euro, p<0.001), the total was not significantly changed (7 777 ± 14 263 Euro vs. 7 321 ± 7 910 Euro, p=0.65). The substantial reduction of inpatient costs was compensated by the additional costs for medication and the costs of the complex outpatient care. Results were comparable for the 2 subgroups of schizophrenic/schizoaffective (n=66, 40.9 vs. 17.9 days, p=0.03; inpatient cost 9 009 ± 15 677 Euro vs. 3 650 ± 8 486 Euro, p=0.02; total expenditures 11 789 ± 15 975 Euro vs. 9 623 ± 9 262 Euro, p=0.33) and unipolar depressive patients (n=90, 29.8 vs. 9.8 days, p=0.006; inpatient cost 5 664 ± 14 921 Euro vs. 1 967 ± 5 276 Euro, p=0.02; total expenditures 7 146 ± 15 164 Euro vs. 6 234 ± 6 292 Euro, p=0.57). CONCLUSION The IC was able to considerably reduce the utilisation of inpatient treatment through offering a complex range of services in the outpatient setting and allowed for a weight-shift in a low-threshold comprehensive care structure without an increase in costs from the statutory health insurance companies' perspective. For a detailed description of clinical effects further studies are required.

Abstract
Physical activity has been recommended based on beneficial effects described in HIV-infected patients. However, such guidelines do not take into account actual sport behaviours and general attitudes towards physical activity. To evaluate actual sport activity and attitudes towards sport in HIV-infected versus non-infected individuals we conducted an anonymous questionnaire investigating the prevalence, as well as possible changes, in sports engagement and the overall attitude to physical activity. A total of 283 patients of a general care facility specialized in the treatment of HIV/AIDS in Berlin, Germany, participated; 124 were HIV infected and 159 were non-infected, mostly men who have sex with men (MSM) (88%), with a median age of 35 years. The HIV-infected participants had a median CD4+ count of 554 cells/µL and 48.8% of them were using antiretroviral therapy (ART) at the time of survey. The proportion of patients actually performing physical activity was significantly lower (P = 0.028) within the HIV-infected group (61.3%) than within the non-infected group (74.2%). This difference remained significant after accounting for possible confounders such as age, gender, injecting drug use and sexual preferences. Previously reported sport activity prevalence was similar in both groups on leaving school. From our data we could not identify an association between the time of HIV diagnosis and changes in sports activity. In conclusion, fewer HIV-infected individuals report physical activity than non-infected individuals. Sociodemographic studies to evaluate potential differences in sports behaviour are required in order to inform exercise guidelines for HIV-infected patients.

Abstract
Warm-up is generally considered beneficial for performance, although the reduction in anaerobic glycolytic metabolism may be detrimental to sprinting. This study examined the effect of warm-up intensity on metabolism and performance in sprint cycling. The mean power was determined during a 1-min sprint on 11 trained males preceded by easy (WE), moderate (WM) or hard (WH) warm-up and a 10-min recovery. Aerobic, anaerobic glycolytic and phosphocreatine energy provision to the sprint was determined from oxygen uptake and lactate production. Blood lactate concentration before the sprint increased with the warm-up intensity (WE: 1.2±0.3; WM: 2.0±0.3; WH: 4.2±0.9 mmol/L, P<0.001), with WH reducing the increase in lactate production during exercise vs WE (WE: 11.6±1.6; WM: 10.9±1.9; WH: 9.2±1.4 mmol/L, P<0.05). Despite the lower relative anaerobic glycolytic energy provision in WH vs WE (WH: 38±5; WM: 36±6; WE: 34±3%, P<0.05), the mean power was unaffected (WE: 516±28; WM: 521±26; WH: 526±34 W, P>0.05) due to increased oxygen uptake in WH during the sprint (WE: 3.2±0.4; WM: 3.3±0.3; WH: 3.4±0.4 liters, P<0.05). This study supports a warm-up-induced reduction in glycolytic rate, although sprint performance, at least of a long duration, may be maintained due to increased oxygen utilization.
