Dance 4 Your Life: Exploring the Health and Well-Being Implications of a Contemporary Dance Intervention for Female Adolescents.

The purpose of this study was to assess the physiological and psychological impact of contemporary dance classes on adolescent females. Fifty‐five females, aged 14 were recruited from secondary schools in the UK. The intervention constituted a program of contemporary dance classes with an emphasis on building muscular strength. Full ethics approval was granted by a Higher Education institutional Research Ethics Committee. A series of physiological and psychological assessments were undertaken pre and post the dance intervention: upper body strength, flexibility, aerobic fitness, self‐esteem, intrinsic motivation, and attitudes toward dance and group physical activities were measured using standard procedures. A paired t‐test was used to analyse changes between pre‐ to post‐testing. There was a statistical increase in areas of physical fitness. Aerobic capacity and upper body strength increased significanlty (p=0.001 and 0.002 respectively). No significant change occurred in flexibility. Self Esteem statistically increased (p=0.01). No change occurred in Intrinsic Motivation, however motivation scores were higher than average at pre‐test stage. Attitudes towards dance were very positive both pre‐ and post‐intervention. This study showed that dance can statistically improve components of physical fitness, and psychological well‐being. Participants demonstrated positive attitudes towards dance.

Energy Intake and Energy Expenditure of Pre-professional Female Contemporary Dancers

Many athletes in aesthetic and weight dependent sports are at risk of energy imbalance. However little is known about the exercise and eating behaviours of highly trained dance populations. This investigation sought to determine the energy intake and energy expenditure of pre-professional female contemporary dancers. Twenty-five female contemporary dance students completed the study. Over a 7-day period, including five week days (with scheduled dance training at a conservatoire) and two weekend days (with no scheduled dance training at the conservatoire), energy intake (self-reported weighed food diary and 24 h dietary recall) and expenditure (tri-axial accelerometry) were recorded. Mean daily energy intake and expenditure were different over the 7-day period (P = 0.014) equating to an energy deficit of -356 ± 668 kcal·day-1 (or -1.5 ± 2.8 MJ·day-1). Energy expenditure was not different when comparing week and weekend days (P = 0.297). However daily energy intake (P = 0.002), energy availability (P = 0.003), and energy balance (P = 0.004) were lower during the week compared to the weekend, where energy balance became positive. The percentage contribution of macronutrients to total energy intake also differed; with higher fat (P = 0.022) and alcohol (P = 0.020), and lower carbohydrate (P = 0.001) and a trend for lower protein (P = 0.051) at the weekend. Energy balance and appropriate macronutrient intake are essential for maintaining the demands of training, performance and recovery. Whilst aesthetics are important, female contemporary dancers may be at risk of the numerous health and performance impairments associated with negative energy balance, particularly during periods of scheduled training.
