Readiness for Dancing En Pointe.
Shah, S
Physical medicine and rehabilitation clinics of North America. 2021;(1):87-102
Abstract
Advancing to pointe requires sufficient maturity, strength, and flexibility and adequate ballet training to develop the skills which usually occurs between the ages 11 and 13. Health practitioners can provide studios with an objective assessment to determine if a young dancer is ready to transition to en pointe. The evaluator should be proficient in ballet, because the evaluation largely is dance based and includes a history and physical examination as well as a comprehensive assessment. The plan includes health improvement tips and summarizes technique flaws as well as exercises to improve these and other deficits. The goal is to transition dancers safely to pointe.

Dancing for Healthy Aging: Functional and Metabolic Perspectives.
Rodrigues-Krause, J, Krause, M, Reischak-Oliveira, A
Alternative therapies in health and medicine. 2019;(1):44-63
Abstract
CONTEXT Dancing has been used as a form of exercise to improve functional and metabolic outcomes during aging. The field lacks randomized, clinical trials (RCTs) evaluating metabolic outcomes related to dance interventions, but dancing may be a form of exercise that could induce positive effects on the metabolic health of older adults. However, primary studies seem very heterogonous regarding the trial designs, characteristics of the interventions, the methods for outcomes assessments, statistical powers, and methodological quality. OBJECTIVE The current research team intended to review the literature on the use of dance as a form of intervention to promote functional and metabolic health in older adults. Specifically, the research team aimed to identify and describe the characteristics of a large range of studies using dance as an intervention, summarizing them and putting them into perspective for further analysis. DESIGN The research team searched the following data sources-MEDLINE, Cochrane Wiley, Clinical Trials.gov, the Physiotherapy Evidence Database (PEDRO), and the Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS)-for RCTs, quasi-experimental studies, and observational trials that compared the benefits of any style of dancing, combined with other exercises or alone, to nonexercising controls and/or controls practicing other types of exercise. SETTING The study took place at the Federal University of Rio Grande do Sul (Porto Alegre, Brazil). PARTICIPANTS Participants were aging individuals, >55 y, both with or without health conditions. INTERVENTIONS Interventions should be supervised, taking form as group classes, in a dance setting environment. Dance styles were divided into 5 categories for the review: (1) cultural dances developed by groups of people to reflect the roots of a certain region, such as Greek dance; (2) ballroom dance (ie, dances with partners performed socially or competitively in a ballroom, such as foxtrot); (3) aerobic dance with no partner required, which mixes aerobic moves with dance moves; (4) dance therapies, whichare special dance programs including emotional and physical aspects; and (5) classical dances, which are dances with a unique tradition and technique, such as ballet or jazz dance. OUTCOME MEASURES Studies needed to have evaluated functional and/or metabolic outcomes. Functional outcomes included (1) static and/or dynamic balance, (2) gait ability, (3) upper and/or lower muscle strength or power, (4) cardiorespiratory fitness, (5) flexibility, (6) risk of falls, and (7) quality of life. Metabolic outcomes included (1) lipid and glycemic profile; (2) systolic and diastolic blood pressure; (3) body composition; and (4) other specific cardiovascular risk factors or inflammatory or oxidative stress markers. RESULTS The research team retrieved 1042 articles, with 88 full texts assessed for eligibility, and 50 articles included in the analysis. Of the analyzed studies, 22 were RCTs evaluating dancing vs controls, and 3 were RCTs evaluating dancing vs other exercise. Regarding the participants of the reviewed studies: (1) 31 evaluated healthy individuals, (2) 7 evaluated patients suffering from Parkinson's disease, (3) 4 evaluated postmenopausal women, (4) 2 evaluated obese women, (5) 2 evaluated patients with chronic heart failure, (6) 1 evaluated frail older adults, (7) 1 evaluated individuals with visual impairments, (8) 1 evaluated persons with metabolic syndrome, and (9) 1 evaluated individuals with severe pain in the lower extremities. Regarding the interventions, most interventions were 12 wk long, 3 ×/wk, for 60 min each session. The dance styles most used were ballroom and cultural dances. Regarding the outcomes, functional and metabolic benefits were described in most of the included studies. Balance was the functional outcome most often assessed. CONCLUSIONS Any dance style can induce positive functional adaptations in older adults, especially related to balance. Metabolic improvements may also be a result of dancing; however, more RCTs are needed. Dancing may be a potential exercise intervention to promote health-related benefits for aging individuals.

Nutrition and nutritional issues for dancers.
Sousa, M, Carvalho, P, Moreira, P, Teixeira, VH
Medical problems of performing artists. 2013;(3):119-23
Abstract
Proper nutrition, not simply adequate energetic intake, is needed to achieve optimal dance performance. However, little scientific research exists concerning nutrition in dance, and so, to propose nutritional guidelines for this field, recommendations need to be based mainly on studies done in other physically active groups. To diminish the risk of energy imbalance and associated disorders, dancers must consume at least 30 kcal/kg fat-free mass/day, plus the training energy expenditure. For macronutrients, a daily intake of 3 to 5 g carbohydrates/kg, 1.2 to 1.7 g protein/kg, and 20 to 35% of energy intake from fat can be recommended. Dancers may be at increased risk of poor micronutrient status due to their restricted energy intake; micronutrients that deserve concern are iron, calcium, and vitamin D. During training, dancers should give special attention to fluid and carbohydrate intake in order to maintain optimal cognition, motivation, and motor skill performance. For competition/stage performance preparation, it is also important to ensure that an adequate dietary intake is being achieved. Nutritional supplements that may help in achieving specific nutritional goals when dietary intake is inadequate include multivitamins and mineral, iron, calcium, and vitamin D supplements, sports drinks, sports bars, and liquid meal supplements. Caffeine can also be used as an ergogenic aid. It is important that dancers seek dietary advice from qualified specialists, since the pressure to maintain a low body weight and low body fat levels is high, especially in styles as ballet, and this can lead to an unbalanced diet and health problems if not correctly supervised.

Overuse, tissue fatigue, and injuries.
Murgia, C
Journal of dance medicine & science : official publication of the International Association for Dance Medicine & Science. 2013;(3):92-100
Abstract
Research has provided abundant evidence that overtraining is associated with fatigue and subsequent injury. For many years, it has been axiomatic that the vast majority of dance injuries are the result of overuse, and that dancers frequently persist in movement activities in the presence of microscopic injury--i.e., "dance through" injuries. While it is well-established fact that rest and adequate nutrition are vital components of training and conditioning, for various reasons it remains problematic for dancers to assimilate these requirements into their daily regimen. This review article provides some physiologically and biomechanically based information about the causes, inter-relationships, and consequences of these fundamental premises in dance science.

Sport-specific biomechanics of spinal injuries in aesthetic athletes (dancers, gymnasts, and figure skaters).
d'Hemecourt, PA, Luke, A
Clinics in sports medicine. 2012;(3):397-408
Abstract
Young aesthetic athletes require special understanding of the athletic biomechanical demands peculiar to each sport. The performance of these activities may impart specific biomechanical stresses and subsequent injury patterns. The clinician must understand these aspects as well as the spinal changes that occur with growth when many of these injuries often occur. Further, athletes, parents, coaches, and healthcare providers must be sensitive to the overall aspects of the athlete, including nutrition, overtraining, adequate recovery, proper technique, and limiting repetition of difficult maneuvers to minimize injuries.

[Dance as a risk factor for injuries and development of occupational diseases].
Janev Holcer, N, Pucarin-Cvetković, J, Mustajbegović, J, Zuškin, E
Arhiv za higijenu rada i toksikologiju. 2012;(2):239-46
Abstract
Injuries and diseases can significantly affect the creativity and artistic performance. The link between working conditions and artistic performance had been recognised as early as the medieval age. Physically demanding performance arts such as dance can sometimes result in injuries, illnesses, inability to perform, and even end artist's career. Dancers are exposed to specific risks and in need of specific medical care. Many dancers often stretch their physical capabilities and endurance and neglect their physical limitations. Their health problems include a number of work-related illnesses that range from stress and stage fright to metabolic and nutritional disorders. They also include musculoskeletal injuries due to overload training that are often the beginning of chronic health problems.

Physical benefits of dancing for healthy older adults: a review.
Keogh, JW, Kilding, A, Pidgeon, P, Ashley, L, Gillis, D
Journal of aging and physical activity. 2009;(4):479-500
Abstract
Dancing is a mode of physical activity that may allow older adults to improve their physical function, health, and well-being. However, no reviews on the physical benefits of dancing for healthy older adults have been published in the scientific literature. Using relevant databases and keywords, 15 training and 3 cross-sectional studies that met the inclusion criteria were reviewed. Grade B-level evidence indicated that older adults can significantly improve their aerobic power, lower body muscle endurance, strength and flexibility, balance, agility, and gait through dancing. Grade C evidence suggested that dancing might improve older adults' lower body bone-mineral content and muscle power, as well as reduce the prevalence of falls and cardiovascular health risks. Further research is, however, needed to determine the efficacy of different forms of dance, the relative effectiveness of these forms of dance compared with other exercise modes, and how best to engage older adults in dance participation.

Foot and ankle fractures in dancers.
Goulart, M, O'Malley, MJ, Hodgkins, CW, Charlton, TP
Clinics in sports medicine. 2008;(2):295-304
Abstract
Fractures in the dance population are common. Radiography, CT, MRI, and bone scan should be used as necessary to arrive at the correct diagnosis after meticulous physical examination. Treatment should address the fracture itself and any surrounding problems such as nutritional/hormonal issues and training/performance techniques and regimens. Compliance issues in this population are a concern, so treatment strategies should be tailored accordingly. Stress fractures in particular can present difficulties to the treating physician and may require prolonged treatment periods. This article addresses stress fractures of the fibula, calcaneus, navicular, and second metatarsal; fractures of the fifth metatarsal, sesamoids, and phalanges; and dislocation of toes.
