This study was a comparison of how selected newspapers from Canada, Great Britain, and the United States reported on female athletes competing in four “gender-appropriate” sports with female athletes competing in four “gender-inappropriate” sports at the Centennial Olympic Games. The liberal feminist theoretical framework underpinning this study views equality of opportunity and individual liberty as an inevitable by-product of political, legal, and educational reform juxtaposed with a gradual social acceptance. Content Analysis was used to examine all the articles and photographs from the front pages and the sports sections of the newspapers. Based upon the data, female athletes competing in the “gender-appropriate” sports of swimming, gymnastics, tennis, and diving received more newspaper coverage than female athletes competing in the “gender-inappropriate” sports of soccer, softball, field hockey, and volleyball in terms of the average number of words per article and the average number of paragraphs per article. In addition, the “gender-appropriate” athletes were over-represented in the average number of photographs, the average number of photographs on the first page, and the average number of photographs on the top of the pages. Qualitative analyses of articles and photographs revealed a subtle but discernable amount of culturally stereotyped coverage.

The aquatic sports competitions held during the summer Olympic Games include diving, open-water swimming, pool swimming, synchronized swimming, and water polo. Elite-level performance in each of these sports requires rigorous training and practice to develop the appropriate physiological, biomechanical, artistic, and strategic capabilities specific to each sport. Consequently, the daily training plans of these athletes are quite varied both between and within the sports. Common to all aquatic athletes, however, is that daily training and preparation consumes several hours and involves frequent periods of high-intensity exertion. Nutritional support for this high-level training is a critical element of the preparation of these athletes to ensure the energy and nutrient demands of the training and competition are met. In this article, we introduce the fundamental physical requirements of these sports and specifically explore the energetics of human locomotion in water. Subsequent articles in this issue explore the specific nutritional requirements of each aquatic sport. We hope that such exploration will provide a foundation for future investigation of the roles of optimal nutrition in optimizing performance in the aquatic sports.

Drawing on data gathered from high-school seniors in the 2008 Monitoring the Future Study of American Youth (N = 2,063), this research examined the explanatory effects of competitive sports participation on alcohol consumption and marijuana use using race and noncompetitive exercise frequency as controls. Among males, competitive sports included baseball, basketball, football, soccer, track and field, and weightlifting, and among females, sports included softball, basketball, soccer, swimming and diving, track and field, and volleyball. White males reported greater alcohol consumption than Black and Hispanic respondents, with competitors in baseball, football and weightlifting consuming alcohol more frequently. The use of marijuana did not depend on race, but baseball players and weightlifters reported significantly more use. Among females, race differences did not emerge in ordinal regression models testing effects on alcohol consumption, but participants in every sport reported drinking alcohol more frequently. White female athletes also appeared to smoke marijuana more frequently. Overall, results suggested comparably strong effects for female sport environments while male behaviors varied by race, noncompetitive exercise frequency, and sports competition. Limitations of the study and recommendations for future research are offered.

The Functional Movement Screen (FMS) evaluates performance in 7 fundamental movement patterns using a 4-point scale. Previous studies have reported increased injury risk with a composite score (CS) of 14/21 or less; these studies were limited to specific sports and injury definition.
To examine the association between FMS CS and movement pattern scores and acute noncontact and overuse musculoskeletal injuries in division I college athletes. An exploratory objective was to assess the association between injury and FMS movement pattern asymmetry.
College athletic facilities.
167 injury-free, college basketball, football, volleyball, cross country, track and field, swimming/diving, soccer, golf, and tennis athletes (males = 89).
The FMS was administered during preparticipation examination.
Main Outcome Measure:
Noncontact or overuse injuries that required intervention from the athletic trainer during the sport season.
FMS CS was not different between those injured (n = 74; 14.3 ± 2.5) and those not (14.1 ± 2.4; P = .57). No point on the ROC curve maximized sensitivity and specificity; therefore previously published cut-point was used for analysis with injury (≤14 [n = 92]). After adjustment, no statistically significant association between FMS CS and injury (odds ratio [OR] = 1.01, 95% CI 0.53–1.91) existed. Lunge was the only movement pattern that was associated with injury; those scoring 2 were less likely to have an injury vs those who scored 3 (OR = 0.21, 95% CI 0.08–0.59). There was also no association between FMS movement pattern asymmetry and injury.
FMS CS, movement patterns, and asymmetry were poor predictors of noncontact and overuse injury in this cohort of division I athletes.

A prevailing theory (and practical application) is that elite performance requires early childhood skill development and training across various domains, including sport. Debate continues whether children specializing early (ie, training/competition in a single sport) have true advantage compared with those who sample various sports early and specialize in a single sport later (adolescence). Retrospective data and case studies suggest either model yields elite status depending upon the sport category (ie, situational: ball games, martial arts, fencing; quantitative: track and feld, swimming, skiing; or qualitative: gymnastics, diving, figure skating). However, potential risks of early specialization include greater attrition and adverse physical/emotional health outcomes. With the advent of the IOC Youth Olympic Games, increased emphasis on global youth competition has unknown implications but also represents a potential platform for investigation. Modification of youth competition formats should be based upon multidisciplinary research on psycho-physiological responses, and technical-tactical behaviors during competition. The assumption that a simple scaled-down approach of adult competitions facilitates the development of technical/tactical skills of youth athletes is not necessarily substantiated with field-based research. Relatively little evidence exists regarding the long-term effects of rigorous training and competitive schedules on children in specific sports. It is clear that more prospective studies are needed to understand the training dose that optimally develops adaptations in youth without inducing dropout, overtraining syndrome, and/or injury. Such an approach should be sport specific as well as gender based. Until such evidence exists, coaches and sport administrators will continue to rely upon their sport-specific dogma to influence programmatic development of our most vulnerable population.

Competitive apnea also known as free diving or breath-hold diving is an increasingly popular sport in which individuals attempt to achieve the greatest possible stationary breath-hold duration (i.e., static apnea) or maximal underwater distance or depth (i.e., dynamic apnea). During apnea, oxygen
