Rationale: 

Rationale DanceUK ‘Fit to Dance’ survey 1994 & 2002 Dance injuries have not decreased significantly over this period. Correlation between smoking and injury. Correlation between psychological problems and injury. Differences between dance training and performance (Wyon et al 2000).

Laban Health Screening Programme: 

Laban Health Screening Programme

Aims: 

Aims To provide information to the dance student about their bodies so that they can develop to their full physical potential and feel empowered in, and responsible for this development. identify those students who are most ‘at risk’ of sustaining an injury while undertaking full time dance training. To gather baseline data (norms) of the current status of dancers. To build on existing screening programmes by introducing new lab and dance specific field based tests. To repeat the screening at several stages of the dance students’ training in order to assess trends and correlations.

This study…: 

This study… Longitudinal research design (two testing periods per yr over 3 yrs) Incorporates lab and dance specific field tests (Welsh, T 2003, Redding et al, 2003) Interdisciplinary

Methods of Pilot Study: 

Methods of Pilot Study Body composition - weight, height, BMI and Skinfolds Core stability assessments Markers were placed on anatomical landmarks* – and digital photos were taken of the front, back and right side view of each student and analysed using Silicon Coach biomechanical software *acromiomclavicular, umbilicus, ASIS, tibial tuberosity, inferior angle of the scapulae, posterior calcaneous, lateral malleolus, greater trochanter

Results: Body Mass Index: 

Results: Body Mass Index DanceUK recommend dancers should be BMI greater than 18. American College of Sports Medicine (ACSM) considers a BMI less than 18.5 = underweight. WHO also state that BMI less than 17.5 is diagnostic criterion for anorexia nervosa. ACSM state that an athlete whose BMI falls below 18.5 should modify training by 10-20%. 13 Laban BA1 dancers (16%) have a BMI below 18.5 (lowest was 15.9) Highest score was 24.9

Slide26: 

The full screening programme will include… Dance aerobic fitness test (Wyon et al 2003) Psychological questionnaire: Test of performance strategies (TOPS) Psychological questionnaire: Self esteem (Rosenberg scale) Open-ended questions that relate to how prepared the dance student feels to enter the audition process and world of professional dance
