The Validity of the Session Rating of Perceived Exertion Method for Measuring Internal Training Load in Professional Classical Ballet Dancers

This study, conducted by a group of scientists from the United Kingdom and Switzerland, investigated the convergent validity of session rating of perceived exertion (s-RPE) with objective measures of internal training load (TL) in professional classical ballet dancers.

The main objective of this study was to investigate the validity of s-RPE as a measure of internal TL in professional classical ballet dancers by examining convergence with two validated measures of TL derived from heart rate (HR). A correlative study design was used between April and October 2019.

Data on HR and s-RPE were collected from 22 dancers (belonging to the Royal Ballet) in a total of 218 ballet classes and rehearsals. However, 11 dancers completed less than 9 sessions, so they were not included in the analysis.

Repeated measures correlations revealed very large positive relationships between s-RPE and objective measures across all sessions (r = 0.81 ± 0.11). Based on these results, the s-RPE method can be considered a valid measure of internal TL in professional classical ballet dancers.

The Physical Attributes Most Required in Professional Ballet: A Delphi Study

Image
This research, conducted by the Institute of Sports Exercise and Health of the University College of London, carried out the Delphi technique (presenting a questionnaire to a group of pre-selected and informed people or experts to obtain their opinion on a given subject) to obtain the most required physical characteristics for classical ballet, grouped and classified in order of importance. 148 participants completed the questionnaire. Most of the respondents were physical therapists and ballet teachers (46 and 44, respectively). Although 6 continents were represented, the majority of respondents were from Western Europe and North America (82 and 34, respectively). The 148 participants listed 34 attributes in total, the most frequent being: overall flexibility, overall strength, turnout, body proportions, and foot and ankle flexibility. Overall flexibility was the attribute most frequently recommended by the expert group. The demands of ballet technique require that dancers have a ...

Overuse Injuries in Professional Ballet: Influence of Age and Years of Professional Practice

Image
This descriptive epidemiological study was conducted between January 1, 2005 and October 10, 2010. The study included dancers who were members of the main Spanish ballet companies and who suffered injuries and were diagnosed and treated in the  Trauma and Orthopaedic Surgery Service at Fremap  in Madrid. To evaluate the influence of age and years of professional practice on the occurrence of injuries, the researchers divided the subjects into 3 age groups: junior (≤ 21 years with a professional average of 2.5 years), intermediate (between 22 and 31 years with a professional average of 7.83 years) and senior (≥ 32 years with a professional average of 16.19 years). Taking into account that the population of these three groups experienced certain variations during the study period, the values of the different parameters were obtained based on the number of registered injuries and not on the number of dancers studied. The prevalence of overuse injuries was 0.239 injuries per 1000 ...
