Introduction: Sleep is essential for athletes and dancers to optimize recovery. Poor sleep negatively affects cognitive function and injury risk in athletes. Increased athletic participation (hours) is associated with decreased total sleep and quality in athletes. Still, information about how sleep is related with exposure hours and injury in collegiate dancers remains unclear. We examined the relationships among the Athlete Sleep Behavior Questionnaire (ASBQ), dance exposure hours (DEHr), and injuries in collegiate dancers over a 7 -month period (August 2019-February 2020).

Methods: Seventy-two dancers (58 female, 14 male; 19.7 ± 1.4 years) completed the 18 question ASBQ at the start of each month (Scale:1 = Never, 5 = Always; Global Scores ≤36 = "good sleep behavior" and ≥42 = "poor sleep behavior"). A DEHr was recorded as 1 hour of dance participation in class, rehearsal, or performance. Injuries were defined as any condition where the dancer sought medical attention, and we calculated an injury rate for total injuries (IR/1000 DEHr). Pearson correlations examined relationships among ASBQ, DEHr, and injuries ( ≤ .05).

Results: Dancers participated in 467.8 ± 45.7 DEHr over 7 months, with 14 dancers suffering 18 injuries (IR = 0.5/1000-DEHr; 95% CI:0.3-0.8). Overall, dancers reported poor sleep behaviors (42.6 ± 6.4). ASBQ scores, DEHr, and injuries in August-October, and December-February were not related, except for a weak positive relationship between ASBQ scores and DEHr in November ( = .28,  = .04).

Conclusions: Sleep, DEHr, and injuries were inconsistently related in collegiate dancers. Sleep and DEHr were only correlated during the month where dancers had 2 performance weeks. While we did not observe this relationship every month, performance weeks may have negatively affected sleep in November. Despite consistent poor sleep, sleep did not seem to negatively affect injury risk during the 7 -month study period. Future researchers should validate the ASBQ in dancers.

Clinical Scenario: Ballet dancers exhibit a high risk of musculoskeletal injuries with around 75% of all injuries attributed to overuse injuries. The high prevalence of chronic injuries suggests contributions caused by abnormal biomechanics in combination with repetitive stress common to ballet. Traditional sports settings implement movement screening tools including the Movement Competency Screen (MCS) and functional movement screen (FMS) to identify factors predisposing athletes to injury.

Dance is physically demanding and often involves unilateral movements performed within a small base of support. Prior authors have reported that dancers use one leg preferentially over the other (ie, lower extremity asymmetry). Increased leg asymmetry-quantified using the Limb Symmetry Index (LSI), is associated with increased injury risk.

The efficacy of Pilates-based exercises on rectus abdominis engagement in comparison with the FITNESSGRAM in Collegiate dancers.

Engagement of the core abdominal muscles is essential to maintain proper alignment, technique, and safety. This study compared the muscular amplitude of the upper and lower rectus abdominis muscles' EMG during six Pilates-based abdominal exercises with the FITNESSGRAM in order to determine which may be more effective for dancers. A sphygmomanometer is used as a training tool for neutral pelvis stability; therefore this study also investigated the muscle activation of the Pilates-based exercises with and without the use of a sphygmomanometer to determine which would be more effective in muscular engagement.

The collegiate environment may exacerbate body image issues and eating disorders (EDs) among dancers. This study seeks to evaluate the complex relationships between body image perceptions, risk of EDs, and nutrition knowledge among collegiate dancers. A convenience sample of collegiate dancers was recruited via announcements, flyers, and email to complete the Body Image Assessment Scale-Body Dimensions (BIAS-BD), anthropometrics, and an electronic survey evaluating ED risk (Eating Attitudes Test; EAT-26), nutrition knowledge, and dietary habits.

Article Synopsis
  • - The study examined the link between dance training volume, body composition, and diet among 33 female collegiate dancers, focusing on their nutritional intake and its impact on their physical status.
  • - Results showed that dancers enrolled in relatively high credit loads but maintained a low-calorie diet, with many consuming less than the recommended amounts of protein and carbohydrates.
  • - There was a positive correlation between lean mass and daily intake of calories, fats, proteins, and leucine, highlighting the importance of adequate nutrition for improving body composition in dancers.
