  abstract  = {Hintergrund: Circa ein Drittel der Patientinnen und Patienten mit fortgeschrittenen Krebserkrankungen ist von psychischen Komorbidit{\"a}ten betroffen und circa die H{\"a}lfte weist eine psychische Belastung im klinisch signifikanten Bereich auf. Zur psychotherapeutischen Behandlung dieser Patientengruppe stehen unterschiedliche psychotherapeutische Interventionen zur Verf{\"u}gung. Die CALM-Therapie, eine manualisierte Kurzintervention im Einzelsetting, ist eine dieser Interventionen. Hier bilden vier Module, welche auf den wichtigsten Anliegen und Belastungsfaktoren von Patientinnen und Patienten mit fortgeschrittenen Krebserkrankungen basieren, den inhaltlichen Rahmen. Ziel: Die Treatment Integrity beschreibt das Maß, inwieweit eine psychotherapeutische Intervention wie vorgesehen umgesetzt wurde. F{\"u}r eine fundierte Interpretation psychotherapeutischer Interventionseffekte sind Kenntnisse {\"u}ber die Treatment Integrity entscheidend. Die vorliegende Arbeit untersuchte Teilaspekte der Treatment Integrity durchgef{\"u}hrter CALM-Therapien im Vergleich zu durchgef{\"u}hrten konventionellen psychoonkologischen Therapien, um einen Beitrag zu einer fundierten Interpretation von Interventionseffekten der CALM-Therapie zu leisten. Methoden: Transkriptionen von zwei CALM-Therapien und zwei Therapien einer konventionellen psychoonkologischen Intervention wurden anhand einer qualitativen Inhaltsanalyse nach P. Mayring untersucht. Im Zentrum stand hierbei ein selbst entwickeltes Kategoriensystem zur Analyse des gesamten Textmaterials. Zus{\"a}tzlich wurden Auff{\"a}lligkeiten bez{\"u}glich Ansprachen von Themenbereichen der CALM-Module unsystematisch beobachtet. Ergebnisse: Die Inhalte der untersuchten CALM-Therapien bezogen sich durchschnittlich zu 99,54\% und die der konventionellen psychoonkologischen Therapien durchschnittlich zu 98,71\% auf die Themenbereiche der CALM-Module. Die ermittelten Werte f{\"u}r einzelne Therapiesitzungen lagen f{\"u}r CALM-Sitzungen zwischen 98,12\% und 100\% und f{\"u}r Sitzungen der konventionellen psychoonkologischen Therapie zwischen 96,20\% und 100\%. Unsystematisch beobachtete Auff{\"a}lligkeiten zeigten, dass die Themenbereiche der CALM-Module zum Teil sehr spezifisch durch die CALM-Therapeutinnen und -Therapeuten angesprochen und vernetzt wurden. Schlussfolgerung: Unter Ber{\"u}cksichtigung von methodischen Grenzen zeigte sich bez{\"u}glich des Anteils von Themenbereichen der CALM-Module innerhalb der beiden untersuchten Therapiegruppen kein maßgeblicher Unterschied. Zus{\"a}tzlich liefert die vorliegende Arbeit Hinweise f{\"u}r einen spezifischen therapeutischen Umgang mit den Themenbereichen der CALM-Module innerhalb der untersuchten CALM-Therapien. Um ermittelte Interventionseffekte der CALM-Therapie fundiert interpretieren zu k{\"o}nnen, sollten zuk{\"u}nftige Untersuchungen unterschiedliche Umgangsweisen von Therapeutinnen und Therapeuten der beiden Therapiegruppen mit den Themenbereichen der CALM-Module genauer in den Blick nehmen.},

Zum Untersuchungszeitpunkt waren ein Drittel der Patienten in kompletter Remission, ein weiteres Drittel nur in klinischer und ein Patient nur in radiologischer Remission. Fast die H{\"a}lfte (47\%) erhielt zu diesem Zeitpunkt keine medikament{\"o}se Therapie mehr. In den objektiven Untersuchungsmethoden (Spiroergometrie und Accelerometrie) konnten keine relevanten Einschr{\"a}nkungen in der k{\"o}rperlichen Fitness und dem durchschnittlichen Aktivit{\"a}tsniveau festgestellt werden. Dennoch nahmen die CNO-Patienten deutlich weniger am Sportunterricht teil und in den Frageb{\"o}gen erzielten sie deutlich schlechtere Werte, die auf eine reduzierte Lebensqualit{\"a}t schließen lassen. Vor allem klagten sie deutlich h{\"a}ufiger {\"u}ber Schmerz und gaben deutlich mehr Sorgen an.

  abstract  = {Background Suicide and non-fatal suicidal behaviour are significant public health issues in Europe requiring effective preventive interventions. However, the evidence for effective preventive strategies is scarce. The protocol of a European research project to develop an optimized evidence based program for suicide prevention is presented. Method The groundwork for this research has been established by a regional community based intervention for suicide prevention that focuses on improving awareness and care for depression performed within the European Alliance Against Depression (EAAD). The EAAD intervention consists of (1) training sessions and practice support for primary care physicians,(2) public relations activities and mass media campaigns, (3) training sessions for community facilitators who serve as gatekeepers for depressed and suicidal persons in the community and treatment and (4) outreach and support for high risk and self-help groups (e.g. helplines). The intervention has been shown to be effective in reducing suicidal behaviour in an earlier study, the Nuremberg Alliance Against Depression. In the context of the current research project described in this paper (OSPI-Europe) the EAAD model is enhanced by other evidence based interventions and implemented simultaneously and in standardised way in four regions in Ireland, Portugal, Hungary and Germany. The enhanced intervention will be evaluated using a prospective controlled design with the primary outcomes being composite suicidal acts (fatal and non-fatal), and with intermediate outcomes being the effect of training programs, changes in public attitudes, guideline-consistent media reporting. In addition an analysis of the economic costs and consequences will be undertaken, while a process evaluation will monitor implementation of the interventions within the different regions with varying organisational and healthcare contexts. Discussion This multi-centre research seeks to overcome major challenges of field research in suicide prevention. It pools data from four European regions, considerably increasing the study sample, which will be close to one million. In addition, the study will gather important information concerning the potential to transfer this multilevel program to other health care systems. The results of this research will provide a basis for developing an evidence-based, efficient concept for suicide prevention for EU-member states.},

  abstract  = {The aim of this study was to evaluate the effect of a repeated sprint training with multi-directional change-of-direction (COD) movements (RSmulti) compared to repeated shuttle sprints (RSS) on variables related to COD speed and reactive agility. Nineteen highly-trained male U15 soccer players were assigned into two groups performing either RSmulti or RSS. For both groups, each training session involved 20 repeated 15 s sprints interspersed with 30 s recovery. With RSmulti the COD movements were randomized and performed in response to a visual stimulus, while the RSS involved predefined 180° COD movements. Before and following the six training sessions, performance in the Illinois agility test (IAT), COD speed in response to a visual stimulus, 20 m linear sprint time and vertical jumping height were assessed. Both groups improved their performance in the IAT (p < 0.01, ES = 1.13; p = 0.01, ES = 0.55). The COD speed in response to a visual stimulus improved with the RSmulti (p < 0.01, ES = 1.03), but not the RSS (p = 0.46, ES = 0.28). No differences were found for 20 m sprint time (P=0.73, ES = 0.07; p = 0.14, ES = 0.28) or vertical jumping height (p = 0.46, ES = 0.11; p = 0.29, ES = 0.12) for the RSmulti and RSS, respectively. In conclusion, performance in the IAT improved with the RSmulti as well as RSS. With the RSmulti however, the COD movements are performed in response to a visual stimulus, which may result in specific adaptations that improve COD speed and reactive agility in young highly trained soccer players.},

  abstract  = {Here, we evaluated the influence of breathing oxygen at different partial pressures during recovery from exercise on performance at sea-level and a simulated altitude of 1800 m, as reflected in activation of different upper body muscles, and oxygenation of the m. triceps brachii. Ten well-trained, male endurance athletes (25.3±4.1 yrs; 179.2±4.5 cm; 74.2±3.4 kg) performed four test trials, each involving three 3-min sessions on a double-poling ergometer with 3-min intervals of recovery. One trial was conducted entirely under normoxic (No) and another under hypoxic conditions \((Ho; F_iO_2 = 0.165)\). In the third and fourth trials, the exercise was performed in normoxia and hypoxia, respectively, with hyperoxic recovery \((HOX; F_iO_2 = 1.00)\) in both cases. Arterial hemoglobin saturation was higher under the two HOX conditions than without HOX (p<0.05). Integrated muscle electrical activity was not influenced by the oxygen content (best d = 0.51). Furthermore, the only difference in tissue saturation index measured via near-infrared spectroscopy observed was between the recovery periods during the NoNo and HoHOX interventions (P<0.05, d = 0.93). In the case of HoHo the athletes' \(P_{mean}\) declined from the first to the third interval (P < 0.05), whereas Pmean was unaltered under the HoHOX, NoHOX and NoNo conditions. We conclude that the less pronounced decline in \(P_{mean}\) during 3 x 3-min double-poling sprints in normoxia and hypoxia with hyperoxic recovery is not related to changes in muscle activity or oxygenation. Moreover, we conclude that hyperoxia \((F_iO_2 = 1.00)\) used in conjunction with hypoxic or normoxic work intervals may serve as an effective aid when inhaled during the subsequent recovery intervals.},

Cardiac and pulmonary function in asymptomatic subjects and the effect of structured dietary programs on cardiac and pulmonary function is unclear. Objective To determine lung and cardiac function in asymptomatic obese adults and to evaluate whether weight loss positively affects functional parameters. Methods We prospectively evaluated bodyplethysmographic and echocardiographic data in asymptomatic subjects undergoing a structured one-year weight reduction program. Results 74 subjects (32 male, 42 female; mean age 42±12 years) with an average BMI 42.5±7.9, body weight 123.7±24.9 kg were enrolled. Body weight correlated negatively with vital capacity (R = -0.42, p<0.001), FEV1 (R = -0.497, p<0.001) and positively with P 0.1 (R = 0.32, p = 0.02) and myocardial mass (R = 0.419, p = 0.002). After 4 months the study subjects had significantly reduced their body weight (-26.0±11.8 kg) and BMI (-8.9±3.8) associated with a significant improvement of lung function (absolute changes: vital capacity +5.5±7.5\% pred., p<0.001; FEV1+9.8±8.3\% pred., p<0.001, ITGV+16.4±16.0\% pred., p<0.001, SR tot -17.4±41.5\% pred., p<0.01). Moreover, P0.1/Pimax decreased to 47.7\% (p<0.01) indicating a decreased respiratory load. The change of FEV1 correlated significantly with the change of body weight (R = -0.31, p = 0.03). Echocardiography demonstrated reduced myocardial wall thickness (-0.08±0.2 cm, p = 0.02) and improved left ventricular myocardial performance index (-0.16±0.35, p = 0.02). Mitral annular plane systolic excursion (+0.14, p = 0.03) and pulmonary outflow acceleration time (AT +26.65±41.3 ms, p = 0.001) increased. Conclusion Even in asymptomatic individuals obesity is associated with abnormalities in pulmonary and cardiac function and increased myocardial mass.

However, the direction of cause and effect has not been solved with finality. The aim of this study was to investigate whether residents' perception of their proximate environment differs depending on their level of PA in transport and recreation. We conducted a cross-sectional survey with residents of six different parts of the city of Cologne, Germany. The sample of 470 adults (52.8\% females; mean age = 35.5 ± 13.8 years) filled in the Global Physical Activity Questionnaire (GPAQ), as well as the European Environmental Questionnaire ALPHA. To distinguish between residents with "low" and "high" PA, we split the samples into two on the basis of the specific median in transport- and recreation-related PA. In the "high" vs. "low" PA group of the overall sample, we noted 4\%-16\% more "PA favourable" environmental perceptions in seven of the 15 environmental variables. Multiple linear regression analyses were performed to investigate associations of socio-demographic correlates and transport- and recreation-related PA on the dependent variables of the environmental perception. In this case, levels of PA were significant predictors for eight of the 15 items concerning environmental perceptions. Thus, the present study introduces the idea that residents with higher levels of transport and recreational PA may perceive their environment in a more "PA-favourable" way than residents with lower levels.},

The majority of studies present a "pyramidal" TID with a high proportion of high volume, low intensity training (HVLIT). Some world-class athletes appear to adopt a so-called "polarized" TID (i.e., significant \% of HVLIT and high intensity training) during certain phases of the season. However, emerging prospective randomized controlled studies have demonstrated superior responses of variables related to endurance when applying a polarized TID in well-trained and recreational individuals when compared with a TID that emphasizes HVLIT or threshold training. The aims of the present review are to: (1) summarize the main responses of retrospective and prospective studies exploring TID; (2) provide a systematic overview on TIDs during preparation, pre-competition, and competition phases in different endurance disciplines and performance levels; (3) address whether one TID has demonstrated greater efficacy than another; and (4) highlight research gaps in an effort to direct future scientific studies.},

  abstract  = {Background This study aimed 1) to provide data estimates concerning overall moderate- and vigorous-intensity physical activity (MVPA) as well as MVPA during work, transport and leisure in Germany and 2) to investigate MVPA and possible associations with socio-demographic correlates. Methods A cross-sectional telephone survey interviewed 2248 representative participants in the age of 18-65 years (1077 men; 42.4±13.4 years; body mass index: 25.3±4.5kg•m-2) regarding their self-reported physical activity across Germany. The Global Physical Activity Questionnaire was applied to investigate MVPA during work, transport and leisure and questions were answered concerning their demographics. MVPA was stratified by gender, age, body mass index, residential setting, educational and income level. To identify socio-demographic correlates of overall MVPA as well as in the domains, we used a series of linear regressions. Results 52.8\% of the sample achieved physical activity recommendations (53.7\% men/52.1\% women). Overall MVPA was highest in the age group 18-29 years (p<.05), in participants with 10 years of education (p<.05) and in participants with lowest income levels <1.500€ (p<.05). Regression analyses revealed that age, education and income were negatively associated with overall and work MVPA. Residential setting and education was positively correlated with transport MVPA, whereas income level was negatively associated with transport MVPA. Education was the only correlate for leisure MVPA with a positive association. Conclusions The present data underlines the importance of a comprehensive view on physical activity engagement according to the different physical activity domains and discloses a need for future physical activity interventions that consider socio-demographic variables, residential setting as well as the physical activity domain in Germany.},

  abstract  = {Die Depression ist eine Erkrankung mit einer hohen Pr{\"a}valenz, die mit einem hohen Risiko f{\"u}r Suizidalit{\"a}t assoziiert ist. Traumata w{\"a}hrend der Kindheit gelten als einer der Hauptrisikofaktoren f{\"u}r Depressionen und Suizide. Die Assoziation einer Hyperaktivit{\"a}t des adrenergen Nervensystems und sowohl Depressionen als auch Suizidalit{\"a}t ist gut belegt. Mit einer antidepressiven Behandlung k{\"o}nnen suizidale Handlungen verhindert werden, jedoch gibt es eine Subgruppe, in der Suizidgedanken w{\"a}hrend der Therapie neu auftreten oder sich intensivieren (TWOSI). W{\"a}hrend bereits mehrere genetische Polymorphismen mit dem Auftreten von Suizidgedanken w{\"a}hrend der Therapie assoziiert werden konnten, gibt es noch keine geeignete Methode, diese Patienten vor Therapiebeginn zu identifizieren, um deren Krankheitsverlauf genauer zu {\"u}berwachen. Im Rahmen unserer Studie untersuchten wir station{\"a}re Patienten mit einer depressiven Episode mittels eines Langzeit-EKGs zur Messung der Herzfrequenz und verschiedener Herzratenvariabilit{\"a}tsparameter. Außerdem wurde bei Studieneinschluss durch einen Selbstbeurteilungsfragebogen verschiedene Formen einer Traumatisierung in der Kindheit erhoben und sowohl bei Aufnahme als auch in den darauffolgenden Wochen eine Fremdbeurteilungsskala zur Erfassung der Suizidgedanken durchgef{\"u}hrt. Dabei zeigte sich, dass elf der insgesamt 89 Patienten ein Neuauftreten oder eine Verschlechterung von Suizidgedanken zeigten. Hierbei stellte sich heraus, dass TWOSI� Patienten schwerwiegendere emotionale Missbrauchserfahrungen in ihrer Kindheit erlebt hatten. Zudem zeigten diese Patienten eine h{\"o}here adrenerge Aktivit{\"a}t, widergespiegelt durch eine erh{\"o}hte Herzfrequenz und eine niedrigere Herzratenvariabilit{\"a}t. Somit k{\"o}nnte sich mit zunehmender Schwere der Kindheitstraumatisierung ein {\"U}berwiegen der sympathischen Aktivit{\"a}t ergeben, und daraus wiederum ein h{\"o}heres Risiko f{\"u}r die Intensivierung der Suizidgedanken w{\"a}hrend der Behandlung. Messungen des autonomen Nervensystems k{\"o}nnten in Zukunft als Werkzeug dienen, Patienten mit einem erh{\"o}hten Risiko f{\"u}r TWOSI zu identifizieren.},

  abstract  = {Die WHO definiert Gesundheit als v{\"o}lliges k{\"o}rperliches, geistiges und soziales Wohlbefinden. W{\"a}hrend diese ganzheitliche Betrachtungsweise seit Menschengedenken nahezu weltweit das Gesundheitswesen pr{\"a}gt, hat die Medizin in Europa mit der naturwissenschaftlichen Erkenntnisrevolution einen Sonderweg eingeschlagen. Hier wird der kranke Organismus in erster Linie als defekter Apparat gesehen, der mit ausgekl{\"u}gelter Technik zu reparieren ist. Aber auch pr{\"a}ziseste Qualit{\"a}tsarbeit st{\"o}ßt dabei oft an Leistungsgrenzen, weil sie als seelenlos erlebt wird. Daher sehen heute viele Fachgebiete die Notwendigkeit, ihre Behandlungskonzepte zu beseelen und ihre Behandlungserfolge auch anhand der subjektiv von Patienten empfundenen Lebensqualit{\"a}t zu beurteilen. F{\"u}r die Ermittlung dieses PRO kommen etablierte psychometrische Testverfahren in Frage, die sich auch f{\"u}r routinem{\"a}ßige Verlaufskontrollen eignen. In der vorliegenden Arbeit wurde am Beispiel der mHE gepr{\"u}ft, welchen Nutzen eine PRO-Bestimmung bei der Verlaufskontrolle haben kann. Dazu wurde eine prospektive Studie mit anf{\"a}nglich 75 Patienten durchgef{\"u}hrt. Alle hatten eine mHE und waren entweder alkoholbedingt oder aus anderen Gr{\"u}nden schwer leberkrank. An vier Terminen im Abstand von sechs Monaten wurden die kognitive Leistungsf{\"a}higkeit und der emotionale Status {\"u}berpr{\"u}ft. Die Patienten zeigten anf{\"a}nglich kognitive Einschr{\"a}nkungen, die sich im Verlauf der individuell abgestimmten Behandlung deutlich verbesserten oder ganz verschwanden. Die globale Testung mit dem MoCA ergab eine hochsignifikante Normalisierung im ersten Behandlungsjahr. Die MoCA-Werte am Studienanfang und -ende waren von der Erkrankungsursache unabh{\"a}ngig. Dieser Befund differenzierte sich in den Spezialtests TMT, PHES und NHPT. Hier zeigten die alkoholbedingt Erkrankten durchweg schlechtere Leistungen als die nicht-alkoholbedingt Erkrankten, erholten sich aber in der Regel auch deutlicher. Die seelische Gestimmtheit gem{\"a}ß BDI-II und die mit dem SF-36 MCS ermittelte psychosoziale Befindlichkeit waren in beiden Patientengruppen von Anfang an vergleichsweise g{\"u}nstig. Dabei hatten die alkoholbedingt Erkrankten die besseren Werte, speziell der BDI-II zeigte bei ihnen nach einem halben Jahr eine zus{\"a}tzliche und bleibende Stimmungsaufhellung an. Der SF-36 PCS zum K{\"o}rpererleben zeigte hingegen, dass sich die alkoholbedingt Erkrankten zu Studienbeginn in einer deutlich schlechteren Verfassung befanden. Diese verbesserte sich aber kontinuierlich, sodass nach 1,5 Jahren kein Unterschied mehr zu den nicht-alkoholbedingt Erkrankten bestand. Aus diesen Befunden und dem reichhaltigen Erfahrungsgut zur Alkoholkrankheit wird geschlossen, dass der Genesungsprozess bei alkoholbedingtem Leberversagen viel komplexer ist als bei nicht-alkoholbedingtem Leberversagen. Er k{\"o}nnte wesentlich mehr Zeit erfordern und wird offensichtlich anders erlebt. Dieser Patientengruppe k{\"o}nnten besondere physio- und gespr{\"a}chstherapeutische Angebote eine große Hilfe sein. Die Arbeit zeigt, dass es m{\"o}glich ist, mit wenig Aufwand komplement{\"a}r zu den klinischen Verlaufsbefunden einen informativen PRO-Bericht zu erhalten. Er hilft Angeh{\"o}rigen und medizinischem Personal, die pers{\"o}nlichen N{\"o}te und Hoffnungen der Patienten besser zu verstehen und gegebenenfalls einen Korrekturbedarf im Umgang zu erkennen. Hinzu kam im vorliegenden Fall die Erkenntnis, dass die alkoholbedingt Erkrankten in ihrem Kranksein anders betroffen waren. Die Gr{\"u}nde daf{\"u}r sind im Nachhinein plausibel, der Sachverhalt als solcher w{\"a}re aber ohne diese Spezialuntersuchung wohl nicht erkannt worden. Das Beispiel der PRO-Ermittlung bei der mHE macht den praktischen Wert einer Ber{\"u}cksichtigung des gesamtheitlichen Gesundheitskonzepts der WHO auch in der technikzentrierten „westlichen Medizin" deutlich.},

  abstract  = {Zinkoxid-Nanopartikel (ZnO-NP) finden in vielen Produkten des t{\"a}glichen Verbrauchs Verwendung. Daten {\"u}ber die toxikologischen Eigenschaften von ZnO-NP werden kontrovers diskutiert. Die menschliche Haut ist in Bezug auf die ZnO-NP Exposition das wichtigste Kontakt-Organ. Intakte Haut stellt eine suffiziente Barriere gegen{\"u}ber NP dar. Bei defekter Haut ist ein Kontakt zu den proliferierenden Stammzellen m{\"o}glich, sodass diese als wichtiges toxikologische Ziel f{\"u}r NP darstellen. Das Ziel dieser Dissertation war die Bewertung der genotoxischen und zytotoxischen Effekte an humanen mesenchymalen Stammzellen (hMSC) durch niedrig dosierte ZnO-NP nach 24 st{\"u}ndiger Exposition, repetitiven Expositionen und im Langzeitversuch bis zu 6 Wochen. Zytotoxische Wirkungen von ZnO-NP wurden mit 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazoliumbromid-Test (MTT) gemessen. Dar{\"u}ber hinaus wurde die Genotoxizit{\"a}t durch den Comet-Assay bewertet. Zur Langzeitbeobachtung bis zu 6 Wochen wurde die Transmissionselektronenmikroskopie (TEM) verwendet. Zytotoxizit{\"a}t nach 24-st{\"u}ndiger ZnO-NP-Exposition war ab einer Konzentration von 50 µg/ml nachweisbar. Genotoxizit{\"a}t konnten bereits bei Konzentrationen von 1 und 10 µg/ml ZnO-NP beschrieben werden. Wiederholte Exposition verst{\"a}rkte die Zyto-, aber nicht die Genotoxizit{\"a}t. Eine intrazellul{\"a}re NP-Akkumulation mit Penetration der Zellorganelle wurde bei einer Exposition bis zu 6 Wochen beobachtet. Die Ergebnisse deuten auf zytotoxische und genotoxisches Effekte von ZnO-NP hin. Bereits geringe Dosen von ZnO-NP k{\"o}nnen bei wiederholter Exposition toxische Wirkungen hervorrufen sowie eine langfristige Zellakkumulation. Diese Daten sollten bei der Verwendung von ZnO-NP an gesch{\"a}digter Haut ber{\"u}cksichtigt werden.},

In this single-center, two-armed randomized, controlled study, overweight women performed 9-weeks (3 sessions·wk\(^{-1}\)) of either Circuit\(_{HIIT}\) (n = 11), or Circuit\(_{combined}\) (n = 8). Peak oxygen uptake and perception of physical pain were increased to a greater extent (p < 0.05) by Circuit\(_{HIIT}\), whereas Circuit\(_{combined}\) improved perception of general health more (p < 0.05). Both interventions lowered body mass, body-mass-index, waist-to-hip ratio, fat mass, and enhanced fat-free mass; decreased ratings of perceived exertion during submaximal treadmill running; improved the numbers of push-ups, burpees, one-legged squats, and 30-s skipping performed, as well as the height of counter-movement jumps; and improved physical and social functioning, role of physical limitations, vitality, role of emotional limitations, and mental health to a similar extent (all p < 0.05). Either forms of these multi-stimulating, circuit-like, multiple-joint training can be employed to improve body composition, selected variables of functional strength, and certain dimensions of quality of life in overweight women. However, Circuit\(_{HIIT}\) improves peak oxygen uptake to a greater extent, but with more perception of pain, whereas Circuit\(_{Combined}\) results in better perception of general health.},

  abstract  = {Purpose: The aim of the study was to evaluate the mucosal immune function and circadian variation of salivary cortisol, Immunoglobin-A (sIgA) secretion rate and mood during a period of high-intensity interval training (HIIT) compared to long-slow distance training (LSD). Methods: Recreational male runners (n = 28) completed nine sessions of either HIIT or LSD within 3 weeks. The HIIT involved 4 × 4 min of running at 90-95\% of maximum heart rate interspersed with 3 min of active recovery while the LSD comprised of continuous running at 70-75\% of maximum heart rate for 60-80 min. The psycho-immunological stress-response was investigated with a full daily profile of salivary cortisol and immunoglobin-A (sIgA) secretion rate along with the mood state on a baseline day, the first and last day of training and at follow-up 4 days after the last day of training. Before and after the training period, each athlete's running performance and peak oxygen uptake (V·O\(_{2peak}\)) was determined with an incremental exercise test. Results: The HIIT resulted in a longer time-to-exhaustion (P = 0.02) and increased V·O\(_{2peak}\) compared to LSD (P = 0.01). The circadian variation of sIgA secretion rate showed highest values in the morning immediately after waking up followed by a decrease throughout the day in both groups (P < 0.05). With HIIT, the wake-up response of sIgA secretion rate was higher on the last day of training (P < 0.01) as well as the area under the curve (AUC\(_{G}\)) higher on the first and last day of training and follow-up compared to the LSD (P = 0.01). Also the AUC\(_{G}\) for the sIgA secretion rate correlated with the increase in V·O\(_{2peak}\) and running performance. The AUC\(_{G}\) for cortisol remained unaffected on the first and last day of training but increased on the follow-up day with both, HIIT and LSD (P < 0.01). Conclusion: The increased sIgA secretion rate with the HIIT indicates no compromised mucosal immune function compared to LSD and shows the functional adaptation of the mucosal immune system in response to the increased stress and training load of nine sessions of HIIT.},

Here we aimed to investigate the effects of IPC of the arms and the legs on repeated running sprint performance with changes-of-direction (COD) movements. Methods: Thirteen moderately-to-well-trained team-sport athletes (7 males; 6 females; age: 24 ± 2 years, size: 175 ± 8 cm, body mass: 67.9 ± 8.1 kg) performed 16 × 30 m all-out sprints (15 s rest) with multidirectional COD movements on a Speedcourt\(^{©}\) with IPC (3 × 5 min) of the legs (IPC\(_{leg}\); 240 mm Hg) or of the arms (remote IPC: IPC\(_{remote}\); 180-190 mm Hg) 45 min before the sprints and a control trial (CON; 20 mm Hg). Results: The mean (±SD) time for the 16 × 30 m multidirectional COD sprints was similar between IPC\(_{leg}\) (Mean t: 16.0 ± 1.8 s), IPC\(_{remote}\) (16.2 ± 1.7 s), and CON (16.0 ± 1.6 s; p = 0.50). No statistical differences in oxygen uptake (mean difference: 0\%), heart rate (1.1\%) nor muscle oxygen saturation of the vastus lateralis (4.7\%) and biceps brachii (7.8\%) between the three conditions were evident (all p > 0.05). Conclusions: IPC (3 × 5 min) of the legs (220 mm Hg) or arms (180-190 mm Hg; remote IPC) applied 45 min before 16 × 30 m repeated multidirectional running sprint exercise does not improve sprint performance, oxygen uptake, heart rate nor muscle oxygen saturation of the vastus lateralis muscle when compared to a control trial.},

  abstract  = {Background: Sit-to-stand height-adjustable desks (HAD) may promote workplace standing, as long as workers use them on a regular basis. The aim of this study was to investigate (i) how common HAD in German desk-based workers are, and how frequently HADs are used, (ii) to identify sociodemographic, health-related, and psycho-social variables of workday sitting including having a HAD, and (iii) to analyse sociodemographic, health-related, and psycho-social variables of users and non-users of HADs. Methods: A cross-sectional sample of 680 participants (51.9\% men; 41.0 ± 13.1 years) in a desk-based occupation was interviewed by telephone about their occupational sitting and standing proportions, having and usage of a HAD, and answered questions concerning psycho-social variables of occupational sitting. The proportion of workday sitting was calculated for participants having an HAD (n = 108) and not-having an HAD (n = 573), as well as for regular users of HAD (n = 54), and irregular/non-users of HAD (n = 54). Linear regressions were conducted to calculate associations between socio-demographic, health-related, psychosocial variables and having/not having an HAD, and the proportion of workday sitting. Logistic regressions were executed to examine the association of mentioned variables and participants' usage of HADs. Results: Sixteen percent report that they have an HAD, and 50\% of these report regular use of HAD. Having an HAD is not a correlate of the proportion of workday sitting. Further analysis restricted to participants having available a HAD highlights that only the 'perceived advantages of sitting less' was significantly associated with HAD use in the fully adjusted model (OR 1.75 [1.09; 2.81], p < 0.05). Conclusions: The present findings indicate that accompanying behavioral action while providing an HAD is promising to increase the regular usage of HAD. Hence, future research needs to address the specificity of behavioral actions in order to enhance regular HAD use, and needs to give more fundamental insights into these associations.},

Biophilic approaches are intended to introduce natural surroundings into the workplace, and preliminary data show positive effects on stress reduction and elevated productivity within the workplace. The primary aim of this pilot study was to analyze changes in workplace sitting time and self-reported habit strength concerning uninterrupted sitting and PA during work, when relocating from a traditional office setting to "active" biophilic-designed surroundings. The secondary aim was to assess possible changes in work-associated factors such as satisfaction with the office environment, work engagement, and work performance, among office staff. In a pre-post designed field study, we collected data through an online survey on health behavior at work. Twelve participants completed the survey before (one-month pre-relocation, T1) and twice after the office relocation (three months (T2) and seven months post-relocation (T3)). Standing time per day during office hours increased from T1 to T3 by about 40 min per day (p < 0.01). Other outcomes remained unaltered. The results suggest that changing office surroundings to an active-permissive biophilic design increased standing time during working hours. Future larger-scale controlled studies are warranted to investigate the influence of office design on sitting time and work-associated factors during working hours in depth.},

No baseline differences and no interaction effects occurred in performance of 6 min run, flexibility, push-ups, balance, and long jump. Classroom-based FunctionalHIIT sessions, performed 4 days per week during 4 weeks did not improve variables related to aerobic endurance performance but enhanced certain parameters of functional strength in schoolchildren. As time is limited in the educational system of schools, FunctionalHIIT during regular school classes could offer a new perspective for increasing functional strength in schoolchildren.},

Each 40 m distance was split into short sprints (2.25-6.36 m) separated by multidirectional COD movements (0°-180°), which were performed in response to an external visual stimulus. All performance and physiological data were validated with variables obtained from a ramp-like treadmill and Yo-Yo intermittent recovery level 2 test (Yo-Yo IR2). The incremental SC test revealed high test-retest reliability for the time to exhaustion (ICC = 0.85, typical error [TE] = 0.44, and CV\% = 3.88), V'O\(_{2peak}\), HR\(_{peak}\), ventilation, and breathing frequency (ICC = 0.84, 0.72, 0.89, 0.77, respectively). The time to exhaustion (r = 0.50, 0.74) of the incremental SC test as well as the peak values for V'O\(_{2}\) (r = 0.59, 0.52), HR (r = 0.75, 0.78), ventilation (r = 0.57, 0.57), and breathing frequency (r = 0.68, 0.68) were significantly correlated (P ≤ 0.01) with the ramp-like treadmill test and the Yo-Yo IR2, respectively. The incremental SC test represents a reliable and valid method to assess peak values for V'O\(_{2}\) and HR with respect to the specific demand of team sport match play by incorporating multidirectional COD movements, decision making, and cognitive components.},

  abstract  = {Exercise and training prescription in endurance-type sports has a strong theoretical background with various practical applications based on threshold concepts. Given the challenges and pitfalls of determining individual training zones on the basis of subsystem indicators (e.g., blood lactate concentration, respiratory parameters), the question arises whether there are alternatives for intensity distribution demarcation. Considering that training in a low intensity zone substantially contributes to the performance outcome of endurance athletes and exceeding intensity targets based on a misleading aerobic threshold can lead to negative performance and recovery effects, it would be desirable to find a parameter that could be derived via non-invasive, low cost and commonly available wearable devices. In this regard, analytics conducted from non-linear dynamics of heart rate variability (HRV) have been adapted to gain further insights into the complex cardiovascular regulation during endurance-type exercise. Considering the reciprocal antagonistic behavior and the interaction of the sympathetic and parasympathetic branch of the autonomic nervous system from low to high exercise intensities, it may be promising to use an approach that utilizes information about the regulation quality of the organismic system to determine training-intensity distribution. Detrended fluctuation analysis of HRV and its short-term scaling exponent alpha1 (DFA-alpha1) seems suitable for applied sport-specific settings including exercise from low to high intensities. DFA-alpha1 may be taken as an indicator for exercise prescription and intensity distribution monitoring in endurance-type sports. The present perspective illustrates the potential of DFA-alpha1 for diagnostic and monitoring purposes as a "global" system parameter and proxy for organismic demands.},

  abstract  = {Background: Until now there has been a reported lack of systematic reports and scientific evaluations of rescue missions during terror attacks. This however is urgently required in order to improve the performance of emergency medical services and to be able to compare different missions with each other. Aim of the presented work was to report the systematic evaluation and the lessons learned from the response to a terror attack that happened in Wuerzburg, Germany in 2016. Methods: A team of 14 experts developed a template of quality indicators and operational characteristics, which allow for the description, assessment and comparison of civil emergency rescue missions during mass killing incidents. The entire systematic evaluation process consisted of three main steps. The first step was the systematic data collection according to the quality indicators and operational characteristics. Second was the systematic stratification and assessment of the data. The last step was the prioritisation of the identified weaknesses and the definition of the lessons learned. Results: Five important "lessons learned" have been defined. First of all, a comprehensive concept for rescue missions during terror attacks is essential. Furthermore, the establishment of a defined high priority communication infrastructure between the different dispatch centres ("red phone") is vital. The goal is to secure the continuity of information between a few well-defined individuals. Thirdly, the organization of the incident scene needs to be commonly decided and communicated between police, medical services and fire services during the mission. A successful mission tactic requires continuous flux of reports to the on-site command post. Therefore, a predefined and common communication infrastructure for all operational forces is a crucial point. Finally, all strategies need to be extensively trained before the real life scenario hits. Conclusion: According to a systematic evaluation, we defined the lessons learned from a terror attack in 2016. Further systematic reports and academic work surrounding life threatening rescue missions and mass killing incidents are needed in order to ultimately improve such mission outcomes. In the future, a close international collaboration might help to find the best database to report and evaluate major incidents but also mass killing events.},
