Objective: To investigate mean creatine kinase (CK) levels in National Collegiate Athletic Association (NCAA) Division I football athletes and the relationship between mean CK levels and demographic variables. Design: Observational cohort. Setting: NCAA Division I football program. Participants: NCAA Division I football athletes. Interventions: Blood and urine samples were obtained from 32 athletes on the first (time 1), third (time 2), and seventh (time 3) days of football camp. Main Outcome Measures: Mean CK levels. The hypotheses were formulated before the data were collected. Results: All urine samples tested negative ...

Early Signs of Osteoarthritis in Professional Ballet Dancers: A Preliminary Study
Conclusions: Early signs of OA, in different joints, were present in a small but highly selected cohort of professional ballet dancers. In future, prospective studies among a number of ballet companies should control for medical and natural history alongside the visual analysis of images and plain radiographs to confirm these preliminary results.

Does Ulnar Variance Change With Age and What Is the Influence of Training and Biological Characteristics in This Change? A Short-term Longitudinal Study in Portuguese Artistic Gymnasts
Conclusions: The gymnasts showed significant longitudinal UV changes toward less negative UV over the training period. Nevertheless, we could not find a significant correlation between UV and the majority of the researched variables. Thus, although UV has been broadly studied, this phenomenon is complex because it depends on different intrinsic and extrinsic factors that are difficult to control, making necessary additional research on this topic. Clinical Relevance: The gymnast's wrist has been associated with a high incidence of painful symptomatology and injuries, leading to the formulation of several hypotheses related...

Comparison of Isokinetic Hip Abduction and Adduction Peak Torques and Ratio Between Sexes
Conclusions: Sex differences in hip abductor strength were observed. The role of weaker hip abductors in females deserves further attention and may be a factor for higher risk of knee pathologies. (Source: Clinical Journal of Sport Medicine)

Analyses of Helsinki 2012 European Athletics Championships Injury and Illness Surveillance to Discuss Elite Athletes Risk Factors
Conclusions: During outdoor EA Championships, injury and illness incidences were slightly lower and injury characteristics were comparable with those during outdoor World Athletics Championships. During elite athletics Championships, gender (male), age (older than 30 years), finals, and some events (combined events and middle- and long-distance races) seem to be injury risk factors. Illness risk factors remain unclear. As in previous recommendations, preventive interventions should focus on overuse injuries, hamstring strains, and adequate rehabilitation of previous injuries, decreasing risk of infectious diseases transmis...

A Mandated Change in Goalie Pad Width Has No Effect on Ice Hockey Goaltender Hip Kinematics
Conclusions: The butterfly movement placed ice hockey goaltenders' hips at their passive limits of hip internal rotation and involved knee forces 1.45 times the body weight. The recent mandated change in goalie pad from 30.5- to 27.9-cm width had no significant effect on hip kinematics. However, previously worn versus new pads did have an effect on hip kinematics.

Body Mass Index, Nutritional Knowledge, and Eating Behaviors in Elite Student and Professional Ballet Dancers
The objective of this study was to examine the association between BMI, eating attitudes, and nutritional knowledge of elite student and professional ballet dancers. Design: Observational design. Setting: Institutional. Participants: One hundred eighty-nine participants from an elite full-time dance school (M = 53, F = 86) and from an elite ballet company (M = 16, F = 25) volunteered for the study. There were no exclusion criteria. Interventions: Anthropometric data (height and mass), General Nutrition Knowledge Questionnaire (GNKQ), and the Eating Attitude Test—26 (EAT-26) were collected from each participant. Main ...

The Role of Magnetic Resonance Imaging in a Division I University Sports Medicine Program
Conclusions: Magnetic resonance imaging was obtained in 14% of athletes and did not demonstrate a clear benefit over history, examination, and radiographs. Magnetic resonance imaging did change diagnosis in 15% of cases, though it did not appreciably change the playing status or treatment plan. (Source: Clinical Journal of Sport Medicine)

Comparison of Tibial Shaft Ski Fractures in Children and Adults
This study analyzed information obtained from 276 patients with tibial fractures sustained during skiing between 2004 and 2012. Main Outcome Measures: We focused on 174 ski-related tibial shaft fractures with respect to the following factors: age, gender, laterality of fracture, skill level, mechanism of fracture (fall vs collision), scene of injury (steepness of slope), snow condition, and weather. Fracture pattern was graded according to Arbeitsgemeinschaft für Osteosynthesefragen (AO) classification and mechanical direction [external (ER) or internal rotation (IR)]. Results: Tibial shaft fractures were the most com...

The Impact of Sex and Knee Injury History on Jump-Landing Patterns in Collegiate Athletes: A Clinical Evaluation
Conclusions: Jump-landing patterns seem to be impacted by sex but not knee injury history. Findings related to sex differences corroborate with previous laboratory-based investigations. Furthermore, findings support the clinical use of the LESS to screen for individuals who may be at risk for a lower extremity injury. Future studies should further investigate the clinical utility of the LESS, particularly its ability to predict lower extremity injuries. (Source: Clinical Journal of Sport Medicine)

Reductions in Intraocular Pressure After Acute Aerobic Exercise: A Meta-Analysis
Conclusions: There is a robust effect of exercise on IOP for sedentary participants. However, the heterogeneity across study parameters, such as exercise protocol, IOP measurement, and participant selection, prohibited the inclusion of studies in this analysis that may have influenced the results. The current analysis makes clear the need for standardization of protocol across this field of research. (Source: Clinical Journal of Sport Medicine)
