Female athletes should aim to achieve energy balance to maintain health and have a high performance output. The purpose of this study was to investigate energy availability (EA) among members of a medium-size Canadian Interuniversity Sport women’s volleyball team and to describe exercise energy expenditure (ExEE) during practices, game warm-ups, and games. Total daily energy expenditure was assessed over 7 d using the Bodymedia Sensewear Mini armband, while energy intake (EI) was measured with dietary food logs. Body composition was assessed using air-displacement plethysmography (Bod Pod). Energy availability was calculated using the equation EA = (EIkcal – ExEEkcal)/kg fat-free mass (FFM). Participants consumed 3,435 (± 1,172) kcal/day and expended 3479 (± 604) kcal/day. Mean EA was 42.5 kcal · kg FFM-1 · d-1 across all 7 d, and 2 participants fell below the 30-kcal · kg FFM-1 · d-1 threshold. Furthermore, participants expended 511 (± 216), 402 (± 50), and 848 (± 155) kcal during practices, game warm-ups, and games, respectively. Overall, the participants were relatively weight stable and should be encouraged to continue fueling their exercise and high ExEE needs with appropriate nutritional strategies.

The present study aimed to explore the interactions and influences that occurred on Twitter after Joey Julius’s (NCAA athlete, Penn State Football) and Mike Marjama’s (MLB player, Seattle Mariners) eating-disorder (ED) diagnoses were revealed. Corresponding with the publicizing of each athlete’s ED, all publicly tagged Twitter media using @joey_julius, Joey Julius, @MMarjama, and Mike Marjama were collected using Netlytic software and analyzed. Text analysis revealed that the conversation was supportive and focused on feelings and size. Social network analysis, based on 5 network properties, showed that Joey Julius invoked a larger conversation but that both athletes’ conversations were single sided. Athlete advocacy on social media should be further explored, as it may contribute to changing societal opinion regarding social issues such as EDs.

ESPN The Magazine’s The Body Issue positions itself as an inclusive and sport-focused publication. With a focus on gender, the purpose of the current study was to examine the online thoughts and opinions that resulted from #BodyIssue on Instagram. In addition, the Instagram posting activity of ESPN (@espn) and espnW (@espnw) as it pertained to the promotion of the featured athletes and the Instagram accounts of the athletes featured in the 2016 Body Issue were explored. A text and network analysis surrounding #BodyIssue for both male and female Body Issue athletes was conducted using the Netlytic program. Manual Instagram tracking of @espn and @espnw, as well as the featured athletes’ accounts, was performed. In its entirety, this study was conducted between June 29 and July 13, 2016. Online thoughts and opinions, although differing by gender, were generally positive, with a large focus on physical form, not sexuality and/or nudity. Furthermore, a gender disparity was reported in regard to ESPN Inc.’s Instagram posting activity, with @espn choosing only to celebrate its male Body Issue athletes on Instagram and @espnw only posting about 2 of the 9 female athletes. There was a significant difference in the number of Instagram followers for the female athletes 1 wk prior to the online release of the issue (M = 105,767.78, SD = 141,193.71) and 1 wk postrelease (M = 109,742.56, SD = 142,890.11), t(8) = −4.29, p = .003. Further analyses of other Body Issue editions is needed to continue investigating this gender disparity and its potential impact on athletes, sport culture, and social attitudes.

Objectives:

To evaluate ultrasound’s effectiveness after eccentric-exercise-induced muscle damage.

Participants:

22 subjects.

Intervention:

Random assignment to ultrasound (UT) or placebo (PT). Ultrasound was applied immediately and 24, 48, and 72 h after 50 maximum eccentric contractions of the biceps.

Outcome Measures:

Concentric and eccentric peak torques, resting elbow angle, and subjective muscle soreness were measured before and 24, 48, 72, and 96 h afterward.

Results:

No significant differences between UT and PT for biceps concentric or eccentric peak torque were noted. Both groups exhibited significant (P < .01) depression in eccentric and concentric peak torques with a slow return toward preexercise values over 96 h. Resting elbow angles for both groups were significantly lower than preexercise values up to 96 h (P < .01). Muscle soreness increased significantly (P < .05) at 24 and 48 h and returned to preexercise levels by 96 h.

Conclusions:

Daily ultrasound did not influence recovery after eccentric-exercise-induced muscle damage.

The purpose was to develop an index of walking performance and to examine gait pattern classifications of children with developmental coordination disorder (DCD). The San Diego database (Sutherland, Olshen, Biden, & Wyatt, 1988) provided data for our calculation of the index and for determining that the index was able to differentiate between gait variables of older (ages 3 to 7) and younger (ages 1 to 2.5) children comprising the database. We obtained cinematographical data on 17 biomechanical markers of 6 boys and 1 girl, ages 6 to 7, with DCD, during walking. Analysis of individuals with DCD gait patterns revealed that most had abnormal walking patterns. The means of the time/distance gait variables did not differ between children with DCD and San Diego children, ages 3 to 7. Children with DCD had much larger variances than other children, indicating no systematic pattern in individual gait differences.
