TY - BOOK ED - Wick, Ditmar ED - Golle, Kathleen ED - Ohlert, Henning T1 - Körperliche und motorische Entwicklung Brandenburger Grundschüler im Längsschnitt : Ergebnisse der EMOTIKON-Studie 2006-2010 N2 - EMOTIKON-Studie benannte als Kurzform des Forschungsvorhabens zur “Interdisziplinäre(n) Evaluierung der motorischen Leistungsfähigkeit und des Gesundheitszustandes im Kontext sportlicher Eignung und Effizienz des Sportunterrichtes von GrundschülerInnen im Land Brandenburg“. Die Längsschnittstudie wurde durch den Arbeitsbereich Trainings- und Bewegungswissenschaft der Universität Potsdam, unter der Leitung von Prof. Dr. Ditmar Wick, an 29 Grundschulen der Schulämter Brandenburg/ Havel und Cottbus von 2006 bis 2010 realisiert. Mit der vorliegenden Publikation werden die Ergebnisse und deren Zusammenhänge zur Entwicklung der motorischen Leistungsfähigkeit, des Körperbaus, der Bewegungsaktivität und der Einschätzung des Sportunterrichts mit einführenden theoretischen Grundlagen und dem aktuellen nationalen Forschungsstand referiert. Die Autoren sind überzeugt, dass dieser Abschlussbericht nicht nur das Interesse der im aktuellen Forschungsprojekt „EMOTIKON-Grundschulsport 2010-2014“ involvierten Brandenburger Grundschulsportlehrer wecken wird, sondern auch den politischen Entscheidungsträgern (Schulämter, Ministerien) eine Entscheidungshilfe bieten als auch den Diskussionsprozess der im Themengebiet forschenden Wissenschaftler anregen kann. Diese Überzeugung gründet sich insbesondere auf die Ergebnisse zur körperlich-sportlichen Bewegungsaktivität der Dritt- bis Sechstklässler sowie der Analyse motorischer Leistung in Abhängigkeit von Geschlecht und soziodemografischen Gegebenheiten.

We propose that standards can be established by video training-programs. Thirty-three German elite basketball referees participated in an online experiment. Feedback during a learning phase influenced decisions (foul vs. no call) in a subsequent test phase. These results provide a starting point for further investigations into establishing standards for referees. They suggest that establishing standards for referees' decisions in ambiguous situations may be a worthwhile approach for improving the quality of referees' decisions.

Using a priming of body parts, this study aimed to differentiate the two processes. Specifically, participants played a motion-controlled video game with either their arms or legs. They then observed arm movements of a point-light actor, which were briefly occluded from view, followed by a static test pose. Participants judged whether this test pose depicted a coherent continuation of the previously seen action (i.e., action prediction task). Evidence of dynamic updating was obtained after compatible effector priming (i.e., arms), whereas incompatible effector priming (i.e., legs) indicated static matching. Together, the results support action prediction as engaging two distinct processes, dynamic simulation and static matching, and indicate that their relative contributions depend on contextual factors like compatibility of body parts involved in performed and observed action.

Neuroenhancement (NE) in everyday life and doping in sport might rest on similar attitudinal representations, and both behaviors can be theoretically modeled by comparable means-to-end relations (substance-performance). A behavioral (not substance-based) definition of NE is proposed, with assumed functionality as its core component. It is empirically tested whether different NE variants (lifestyle drug, prescription drug, and illicit substance) can be regressed to school stressors. Findings: Participants were 519 students (25.8 +/- 8.4 years old, 73.1% female). Logistic regressions indicate that a modified doping attitude scale can predict all three NE variants. Multiple NE substance abuse was frequent. Overwhelming demands in school were associated with lifestyle and prescription drug NE. Conclusions: Researchers should be sensitive for probable structural similarities between enhancement in everyday life and sport and systematically explore where findings from one domain can be adapted for the other. Policy makers should be aware that students might misperceive NE as an acceptable means of coping with stress in school, and help to form societal sensitivity for the topic of NE among our younger ones in general.

HypothesisCompared to plain old balloon angioplasty (POBA) or repeat DES implantation, drug-coated balloon (DCB) angioplasty is a cost-effective therapy for DES-ISR. MethodsA Markov state-transition model was used to compare DCB angioplasty with POBA and repeat DES implantation. Model input parameters were obtained from the literature, and the cost analysis was conducted from a German healthcare payer's perspective. Extensive sensitivity analyses were performed. ResultsInitial procedure costs amounted to Euro3488 for DCB angioplasty and to Euro2782 for POBA. Over a 6-month time horizon, the DCB strategy was less costly (Euro4028 vs Euro4169) and more effective in terms of life-years (LYs) gained (0.497 versus 0.489) than POBA. The DES strategy incurred initial costs of Euro3167 and resulted in 0.494 LYs gained, at total costs of Euro4101 after a 6-month follow-up. Thus, DCB angioplasty was the least costly and most effective strategy. Base-case results were influenced mostly by initial procedure costs, target lesion revascularization rates, and the costs of dual antiplatelet therapy. ConclusionsDCB angioplasty is a cost-effective treatment option for coronary DES-ISR. The higher initial costs of the DCB strategy compared to POBA or repeat DES implantation are offset by later cost savings.

Sie machen darin ganz spezifische Erfahrungen. Hieraus entwickeln sich auch motivationale Orientierungen. Dadurch werden andere Erfahrungen gemacht, die Sportler können andere Motivation und Volition entwickeln. Dabei sind mehr kollektivistische Kulturen eher vermeidungs-motiviert und mehr individualistische Kulturen mehr erfolgsorientiert. Beim Kollektivismus erscheint die Leistungsmotivation eher unter einem sozialen Aspekt, nämlich die Auseinandersetzung mit einem Gütemaßstab, der eher von außen vorgegeben wird und weniger einem ausschließlich eigenen Maßstab. Ägypten erweist sich im Vergleich zu Deutschland als eine eher kollektivistisch geprägte Kultur. Daraus ergeben sich folgende Unterschiede: Einen signifikanten Unterschied zwischen deutschen und ägyptischen Ringern gibt es in der Wettkampforientierung und bei der Sieg- bzw. Gewinn-Orientierung. Die ägyptischen Ringer habe eine höhere Ausprägung als die Deutschen. Sie weisen auch eine etwas höhere Zielorientierung auf als die Deutschen. Entgegen den Erwartungen zeigte sich, dass es keine signifikanten Unterschiede zwischen den ägyptischen und deutschen Ringern gibt in der Variable: Sieg- bzw. Gewinn-Orientierung. Die Furcht vor Misserfolg sowie auch die Hoffnung auf Erfolg liegen höher bei den Ägyptern als bei den Deutschen. Bezogen auf die Modi der Handlungskontrolle verfügen die Deutschen Ringer über eine höher Ausprägung auf allen drei Komponenten. Sie haben eine höhere Handlungsorientierung nach Misserfolg, eine höhere Handlungsplanung sowie eine höhere Handlungstätigkeitsausführung. Diese kulturell kontrastive Studie über die psychologischen Aspekte, im Bereich der Leistungsmotivation und der Handlungskontrolle, kann für die Sportart Ringen sehr nützlich werden, da sie sehr wichtig ist beim Erkennen der sportlichen Überlegenheits- und Schwächemerkmale. Sie wiederspiegelt auch die Hochstimmung in den entwickelten Staaten oder die Misere in den anderen Staaten. Aus den interkulturellen Unterschieden in der Motivation und Volition können somit verschiedene Maßnahmen zu sportpsychologischen Interventionen entwickelt werden. Es sollte unbedingt darauf wert gelegt werden, dass die kulturell bedingten Unterschiede im Trainingsalltag beachtet werden, bei Teams, die aus Personen aus unterschiedlichen Kulturkreisen stammen. N2 - Culture gives people a guide. They make very specific experiences. So they develop motivational orientations. Because other experiences are made, the athlete can develop other motivation and volition. While more collectivist cultures have more avoidance motivation the individualistic cultures are more performance-oriented. In collectivism appears motivation rather from a social aspect, namely the examination of a quality standard that is more externally determined and less an exclusively own scale. Egypt proves to be compared to Germany as a more collectivist influenced culture. This has the following differences: There are significant differences between German and Egyptian wrestlers in the competition orientation and the victory or profit-orientation. The Egyptian wrestlers have higher levels than the Germans. They also have a slightly higher goal orientation than the Germans. Contrary to expectations, it was found that there were no significant differences between the Egyptian and German wrestlers in the variable: victory or profit-orientation. The fear of failure and the hope of success are higher among Egyptians than the Germans. Based on the modes of action control, the Germans have a higher expression of wrestlers on all three components. They have a higher action orientation after failure, a higher action planning and a higher activity of action execution. This culturally contrastive study of the psychological aspects in the field of achievement motivation and executive control, can be very useful for the sport of wrestling, as it is very important in recognizing the athletic superiority and weak features. It also reflects the high spirits in the developed countries or the misery in the other states. From the intercultural differences in the motivation and volition thus several measures to sport psychological interventions are developed. Care should be made not worth that culturally specific differences were observed in the daily training, in teams that come from people from different cultures.

Drop jumps and landings were assessed on a force plate under stable and unstable (balance pad on top of the force plate) conditions. Performance measures (contact time, jump height, peak ground reaction force) and electromyographic (EMG) activity of leg and trunk muscles were tested in 27 subjects (age 23 +/- A 3 years) during different time intervals (preactivation phase, braking phase, push-off phase). The performance of drop jumps under unstable compared to stable conditions produced a decrease in jump height (9 %, p < 0.001, f = 0.92) and an increase in peak ground reaction force (5 %, p = 0.022, f = 0.72), and time for braking phase (12 %, p < 0.001, f = 1.25). When performing drop jumps on unstable compared to stable surfaces, muscle activity was reduced in the lower extremities during the preactivation, braking and push-off phases (11-25 %, p < 0.05, 0.48 a parts per thousand currency sign f a parts per thousand currency sign 1.23). Additionally, when landing on unstable compared to stable conditions, reduced lower limb muscle activities were observed during the preactivation phase (7-60 %, p < 0.05, 0.50 a parts per thousand currency sign f a parts per thousand currency sign 3.62). Trunk muscle activity did not significantly differ between the test conditions for both jumping and landing tasks. The present findings indicate that modified feedforward mechanisms in terms of lower leg muscle activities during the preactivation phase and/or possible alterations in leg muscle activity shortly after ground contact (i.e., braking phase) are responsible for performance decrements during jumping on unstable surfaces.
