Dies zeigen Analysen öffentlich eingesetzter Berufsverzeichnisse ab 1927 sowie Beschäftigungsdaten, Arbeitslosenzahlen und Daten zu offen gemeldeten Stellen der Bundesagentur für Arbeit. Diese wurden für eine Vielzahl von Sportberufen ab 1997 erstmals ausgewertet. Die Bedeutung von Sportberufen in Berufsverzeichnissen ist gewachsen. Neue Berufe fanden bei entsprechender Arbeitsmarktbedeutung Eingang in die Verzeichnisse. Vereinzelt zeigen sich auch neuere Sporttrends. Ferner gab es seit 1999 eine außergewöhnliche Zunahme geringfügig Beschäftigter in allen betrachteten Berufsordnungen mit Sportberufen, teils auch eine Zunahme der sozialversicherungspflichtig Beschäftigten. Fast ausnahmslos waren die Entwicklungen in beiden Beschäftigungsarten in den untersuchten Berufsordnungen weit günstiger als im übergeordneten Berufsumfeld. Für den überwiegenden Teil der Sportberufe ergab sich ein solches Ergebnis auch bei Betrachtung der Arbeitslosenzahlen, die von Anfang 1998 bis Ende 2004 ausgewertet wurden. Demgegenüber wurden der Bundesagentur für Arbeit für fast alle sportbezogenen Berufsklassen 2006 weniger offene ungeförderte Stellen gemeldet als noch 2000. Diese Entwicklung war jedoch nicht ausschließlich für die Berufsklassen im Sport zu beobachten. So sprechen die Ergebnisse zumindest für eine vergleichsweise gute Arbeitsmarktentwicklung in den meisten untersuchten Sportberufen. Die große Zunahme geringfügiger Beschäftigung zeigt aber, dass hier vor allem keine als Haupterwerbsquelle geeigneten Beschäftigungen entstanden sind. Dies reduziert zugleich die Chancen, mit diesen Berufen Arbeitslosigkeit zu reduzieren. N2 - The expansion and increasing pluralism in the field of sports-related occupations and career-paths are both evident in the official labour market statistics. This view is supported by the analysis of publicly accessible career indexes since 1927, as well as employment data of the German Federal Employment Agency. The latter first evaluated occupations associated with sports from 1997 onwards. The public standing or recognition of occupations and career paths in the field of sports has since increased substantially. New occupations found their way into career indexes and there are also a growing number of new sports trends. Furthermore there has been an extraordinary increase in the field of part-time or low-income employment in the field of sport. A more moderate increase in the number of full-time positions has been noticed. This was also supported by the analysis of employment data covering the years from 1998 to 2004. In contrast, the Federal Employment Agency registered fewer open positions during 2006 than in 2000. This development was, however, not only observed in the field of sports associated occupations. Consequently the results suggest a comparatively positive labour market development for sports occupations. Yet, the great increase among the part-time and low-income positions indicates that almost no full-time, high-income positions have been generated. This simultaneously reduces the chances of reducing unemployment through promoting such occupations and careers.

A literature search was conducted in the electronic databases PubMed, Web of Science and Scopus using keywords related to the main topic of this study (e.g., “ballistic” and “plyometric”). According to the PICOS framework, the population for the review was restricted to soccer players, involved in jump or plyometric training. Among 7556 identified studies, 90 were eligible for inclusion. Only 12 studies were found for females. Most studies (n = 52) were conducted with youth male players. Moreover, only 35 studies determined the effectiveness of a given jump training programming factor. Based on the limited available research, it seems that a dose of 7 weeks (1–2 sessions per week), with ~80 jumps (specific of combined types) per session, using near-maximal or maximal intensity, with adequate recovery between repetitions (<15 s), sets (≥30 s) and sessions (≥24–48 h), using progressive overload and taper strategies, using appropriate surfaces (e.g., grass), and applied in a well-rested state, when combined with other training methods, would increase the outcome of effective and safe plyometric-jump training interventions aimed at improving soccer players physical fitness. In conclusion, jump training is an effective and easy-to-administer training approach for youth, adult, male and female soccer players. However, optimal programming for plyometric-jump training in soccer is yet to be determined in future research.

Methods: A retrospective data analysis of 718 orthopedic presentations among 381 adolescent elite athletes from 16 different sports to a sports medical department was performed. Recorded data of history and clinical examination included area, cause and structure of acute and overuse injuries. Injury-events were analyzed in the whole cohort and stratified by age (11–14/15–17 years) and sex. Group differences were tested by chi-squared-tests. Logistic regression analysis was applied examining the influence of factors age, sex, and body mass index (BMI) on the outcome variables area and structure (a = 0.05). Results: Higher proportions of injury-events were reported for females (60%) and athletes of the older age group (66%) than males and younger athletes. The most frequently injured area was the lower extremity (47%) followed by the spine (30.5%) and the upper extremity (12.5%). Acute injuries were mainly located at the lower extremity (74.5%), while overuse injuries were predominantly observed at the lower extremity (41%) as well as the spine (36.5%). Joints (34%), muscles (22%), and tendons (21.5%) were found to be the most often affected structures. The injured structures were different between the age groups (p = 0.022), with the older age group presenting three times more frequent with ligament pathology events (5.5%/2%) and less frequent with bony problems (11%/20.5%) than athletes of the younger age group. The injured area differed between the sexes (p = 0.005), with males having fewer spine injury-events (25.5%/34%) but more upper extremity injuries (18%/9%) than females. Regression analysis showed statistically significant influence for BMI (p = 0.002) and age (p = 0.015) on structure, whereas the area was significantly influenced by sex (p = 0.005). Conclusion: Events of soft-tissue overuse injuries are the most common reasons resulting in orthopedic presentations of adolescent elite athletes. Mostly, the lower extremity and the spine are affected, while sex and age characteristics on affected area and structure must be considered. Therefore, prevention strategies addressing the injury-event profiles should already be implemented in early adolescence taking age, sex as well as injury entity into account.
