TY - THES A1 - Schneider, Dominik T1 - Systematische Videoanalyse von Verletzungen im Profibasketball der Männer T1 - Systematic video analysis of injuries in professional men's basketball N2 - Bisher gibt es nur wenige Forschungsarbeiten, die sich mit der videogestützten Analyse von Basketballverletzungen beschäftigen. In der vorliegenden Arbeit wurden Basketballverletzungen der ersten Basketballbundesliga und der zweiten Basketballbundesliga systematisch per Video analysiert, mit dem Ziel, Verletzungsmuster zu beschreiben und somit gegebenenfalls die Rate von Basketballverletzungen durch geeignete Präventionsansätze zu reduzieren. Hierbei wurden Daten hinsichtlich der Rahmenbedingungen, des Orts der Verletzung, der Spielsituation, der Auslöser und der Umstände der Verletzung an sich zu 215 Verletzungen mit Hilfe eines speziell für die videogestützte Analyse von Basketballverletzungen entwickelten Beobachtungsbogens erhoben. Es zeigte sich in 38% der erhobenen Fälle das Bewegungsmuster Landung zum Verletzungszeitpunkt, was somit das häufigste zu Verletzungen führende Bewegungsmuster war. Oft waren gerade die die athletische Spielweise des Basketballs charakterisierenden Spielaktionen (z. B. Korbleger bzw. Dunking und Shotblock) Auslöser von Verletzungen. Zudem ereigneten sich die Verletzungen im zweiten Viertel 2,1-fach häufiger und im vierten Viertel 1,9-fach häufiger im Vergleich zu den anderen beiden Vierteln. Ein weiteres wichtiges Resultat war, dass die Verletzungen in der Mehrzahl der Fälle (80%) nicht auf ein Foulspiel zurückzuführen waren. Insgesamt ergibt sich aus den Erkenntnissen die Empfehlung der Implementierung von neuromuskulären Präventionsprogrammen, welche die besonderen Verletzungsmechanismen des Basketballs miteinbeziehen. Bisherige Präventionsprogramme können aufgrund dieser Datenlage bezüglich der Bewegungsmuster, der Spielposition, des Verletzungszeitpunkts und des Kontaktmechanismus sowie der individuellen Voraussetzungen des jeweiligen Spielers verwendet werden. Die Umsetzung sollte von Trainern/-innen mitgetragen und überprüft werden. Foulregeländerungen müssen gemäß der vorliegenden Untersuchung – in Hinblick auf die Verletzungsprävention nicht durchgeführt werden. Bezüglich der Resultate hinsichtlich des Verletzungszeitpunkts könnte nach Detektion der genauen Ursachen für eine gehäufte Anzahl an Verletzungen in bestimmten Spielabschnitten durch weitere Studien eine Regeländerung mit Verlängerung der Viertelpausen erwogen werden. N2 - To date, there has been little research that has focused on video-based analysis of basketball injuries. In the present work, basketball injuries of the first and second German national basketball league were systematically analyzed by video with the aim to describe injury patterns and thus, if applicable, to reduce the rate of basketball injuries by suitable prevention approaches. For this purpose, data regarding the general conditions, the location of the injury, the game situation, the triggers and the circumstances of the injury itself were collected for 215 injuries using an observation form specially developed for the video-based analysis of basketball injuries. It appeared in 38% of the collected cases the movement pattern landing at the time of injury, which was thus the most common movement pattern leading to injuries. Often, the game actions that characterize the athletic style of basketball (e.g., lay-up or dunking and shot blocking) were the triggers of injuries. In addition, injuries occurred 2.1 times more frequently in the second quarter and 1.9 times more frequently in the fourth quarter compared to the other two quarters. Another important finding was that in the majority of cases (80%), the injuries were not due to foul play. Overall, the findings lead to the recommendation of implementing neuromuscular prevention programs that incorporate the unique injury mechanisms of basketball. Previous prevention programs can be used based on these data regarding movement patterns, playing position, time of injury, contact mechanism and the individual conditions of each player. Implementation should be shared and reviewed by coaches. According to the present study, foul rule changes with regard to injury prevention do not need to be implemented. With regard to the results concerning the time of injuries, a rule change with extension of the quarter breaks could be considered after detection of the exact causes for a clustered number of injuries in certain game sections by further studies.

Methods In Germany, injuries are registered with the statutory accident insurance for professional athletes (VBG) by clubs or club physicians as part of occupational accident reporting. Moderate and severe injuries (absence of > 7 days) sustained during basketball competition in one of four seasons (2014–2017 and 2018–2019) in the first or second national men’s league in Germany were prospectively analyzed using a newly developed standardized observation form. Season 2017–2018 was excluded because of missing video material. Results Video analysis included 175 (53%) of 329 moderate and severe match injuries. Contact patterns categorized according to the different body sites yielded eight groups of typical injury patterns: one each for the head, shoulders, and ankles, two for the thighs, and three for the knees. Injuries to the head (92%), ankles (76%), shoulders (70%), knees (47%), and thighs (32%) were mainly caused by direct contact. The injury proportion of foul play was 19%. Most injuries (61%) occurred in the central zone below the basket. More injuries occurred during the second (OR 1.8, p = 0.018) and fourth quarter (OR 1.8, p = 0.022) than during the first and third quarter of the match. Conclusion The eight identified injury patterns differed substantially in their mechanisms. Moderate and severe match injuries to the head, shoulders, knees, and ankles were mainly caused by collision with opponents and teammates. Thus, stricter rule enforcement is unlikely to facilitate safer match play.

JF - Cells N2 - As viruses are obligatory intracellular parasites, any step during their life cycle strictly depends on successful interaction with their particular host cells. In particular, their interaction with cellular membranes is of crucial importance for most steps in the viral replication cycle. Such interactions are initiated by uptake of viral particles and subsequent trafficking to intracellular compartments to access their replication compartments which provide a spatially confined environment concentrating viral and cellular components, and subsequently, employ cellular membranes for assembly and exit of viral progeny. The ability of viruses to actively modulate lipid composition such as sphingolipids (SLs) is essential for successful completion of the viral life cycle. In addition to their structural and biophysical properties of cellular membranes, some sphingolipid (SL) species are bioactive and as such, take part in cellular signaling processes involved in regulating viral replication. It is especially due to the progress made in tools to study accumulation and dynamics of SLs, which visualize their compartmentalization and identify interaction partners at a cellular level, as well as the availability of genetic knockout systems, that the role of particular SL species in the viral replication process can be analyzed and, most importantly, be explored as targets for therapeutic intervention.
