Questionnaires were distributed to investigate body mass index (BMI) and menstrual patterns in female dancers aged 12 to 17 years. The study cohort consisted of 105 dancers, mean age 14.8 ± 1.1 years, and mean BMI 19.5 ± 2.3 kg/m. In all, 92% were healthy weight for height. First menses age ranged from 10 to 15 years (mean 12.9 ± 1.1 years). A total of 44% reported irregular menses; of those, 14% described irregularity as "every other month," 37% as "every 3 months," and 49% as "skips a month occasionally." A total of 36% of the dancers stop getting their menses during times of increased activity/dance, and 30% have gone >3 months at any time without getting their menses. A significant negative correlation between BMI and age of first menses was found with lower BMI associated with increased age of first menses (linear regression, β = -0.49, P = .021). This study supports an association between BMI and age of menarche among young female dancers. Given bone health reliance on hormonal milieu in female dancers, future research is warranted.
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 study focused on pre-professional female adolescent dancers to examine the prevalence of delayed bone maturation and menstrual cycle irregularities, as well as their potential links to low back pain (LBP).
- Findings revealed that while many dancers experienced delayed bone maturation (32%) or menstrual cycle issues (53%), these conditions were not linked to LBP; however, those with a history of LBP started dancing at a younger age and had noticeable hip rotation differences.
- The conclusion emphasized that while certain physical impairments were common among the dancers, only early dance training, hip asymmetry, and reduced internal hip rotation were significantly associated with the occurrence of LBP.
Introduction: To the best of our knowledge, no previous studies have linked the progression of hallux valgus (HV) with plantar pressure distribution. Therefore, this study aimed to determine the progression of HV angle in elite adolescent dancers and evaluate the risk factors associated with foot plantar pressure during demi-pointe movement.
Methods: For this cohort study, 40 adolescent dancesport dancers (age: 14.
A gait analysis serves as a critical tool for examining the biomechanical differences in movement patterns between trained and untrained individuals. This study investigates the nuanced differences in gait patterns between professional ballet dancers and non-dancers, with a focus on angular velocities and accelerations across key body joints. By analyzing the positions and movements of the head, neck, shoulder, spine, hip, knee, and ankle in both the sagittal (SP) and frontal (FP) planes, the study aims to identify key distinctions in joint dynamics that arise from differing levels of physical training.
Introduction: Research has described improved health for persons with Parkinson's Disease (PD) who participate in dance classes. However, few studies focus on how relatives experience their life together with a partner who has PD and how the impact of Dance for Parkinson's Disease (DfPD) influences everyday life.
Objective: The aim of the study was to identify and describe the impact of DfPD on subjective experiences of well-being and functioning in daily living as experienced by dancers and their relatives.
