Characterization of Injuries in Male and Female Ultimate Frisbee Players at the Elite Club-Level

# Background Ultimate Frisbee is a rapidly growing sport played in all levels of competition in men’s, women’s, and coed divisions. Despite widespread popularity, there remains a lack of research on injury risk and prevalence during a season. # Purpose To determine the prevalence of injuries among elite club-level men and women Ultimate Frisbee players and to identify elements associated with injury during a single season. # Study Design Descriptive epidemiological study. # Methods Voluntary preseason and postseason online surveys were distributed to local elite club-level Ultimate teams in 2019. Surveys assessed players’ lifetime Ultimate-associated injury history, injury status, training regimen, and other related elements. # Results Fifty-seven and 84 players were eligible to complete the preseason and postseason surveys, respectively. Prior to the 2019 season, 97% of female respondents and 100% of male respondents reported a previous Ultimate-related injury in their career, with all reporting a prior lower extremity injury. During the 2019 season, 56% of respondents reported being injured, and 12% missed one month or more of the season, with 88% of injured players reporting a lower extremity injury. Men reported more ankle and calf injuries than women, and there was a strong negative correlation between time missed due to injury during the 2018 season and the number of days per week spent weight-training and accumulated training. # Conclusion There is a high prevalence of lower extremity injury among elite club-level Ultimate players during a single season and pervasive lower extremity injury history may contribute to high injury prevalence. Observed injury patterns suggest targeted interventions including Nordic Hamstring Exercises and balance and proprioceptive training may decrease injury risk. Further research into this topic is needed to help reduce injury in these athletes. # Levels of Evidence Level 3

The use of the Brain Jogging in the occupational therapy focusing on patients after cranio trauma

Bakalářská práce se věnuje tématu ,,Využití Brain Jogging v ergoterapii pacientů po kraniotraumatech" a je rozdělena na teoretickou a praktickou část. V teoretické části jsou shrnuty základní informace o kraniocerebrálním poranění, neurorehabilitaci a kognitivních funkcí. Další kapitoly obsahují základní poznatky o kognitivní rehabilitaci v ergoterapii a o programu Happy Neuron. Praktická část práce se zabývá kognitivní rehabilitací pomocí programu Happy Neuron u klientů po kraniotraumatu a také tím, jak program ovlivní jejich deficit v oblasti soběstačnosti a kognitivních funkcí. Dále jsou k praktické části přiřazeny kazuistiky a stanoveny cíle s hypotézami.Katedra fyzioterapie a ergoterapieObhájenoBachelor thesis focuses on the topic ,,The use of the Brain Jogging in the occupational therapy focusing on patients after cranio trauma" and is divided into theoretical and practical part. The theoretical part summarizes basic information about traumatic brain injury , neurorehabilitation , and cognitive function. Other chapters include basic knowledge about cognitive rehabilitation in occupational therapy and about program Happy Neuron . The practical part deals with cognitive rehabilitation using Happy Neuron with clients after cranio trauma and how the program will affect their deficit in self-sufficiency and cognitive functions. There are also practical part of the assigned case studies and set goals hypotheses

Isotope ratios of H, C, and O in CO2 and H2O of the Martian atmosphere

Stable isotope ratios of H, C, and O are powerful indicators of a wide variety of planetary geophysical processes, and for Mars they reveal the record of loss of its atmosphere and subsequent interactions with its surface such as carbonate formation. We report in situ measurements of the isotopic ratios of D/H and O-18/O-16 in water and C-13/C-12, O-18/O-16, O-17/O-16, and (CO)-C-13-O-18/(CO)-C-12-O-16 in carbon dioxide, made in the martian atmosphere at Gale Crater from the Curiosity rover using the Sample Analysis at Mars (SAM)'s tunable laser spectrometer (TLS). Comparison between our measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established similar to 4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing
