‘Occupational marks’

Occupational marks represent the effects of a repeated particular activity on a worker’s, musician’s or sportsperson’s skin. They are many and varied. They include (but are by no means limited to) : • Surfer’s Nodules (Surfers) • Cauliflower Ear (Boxers) • Jazz Ballet Bottom (Dancers) • Lichenification of the Elbows (Bank workers) • Alopecia from […]

Does leg length play a determinative role for success in ballet? [research study]

A unique 2009 research project quantified (for the first time) the changes in elevation angles of ballet dancers’ legs between 1946 and 2004. Now a new study has examined (again for the first time) leg-length in relation to selected ballet performance indicators. “The aim of the present study was to investigate the relationships between leg […]

Ballet Dancers doing splits in an MRI scanner [hip study]

Quite a number of professional ballet dancers suffer from medical conditions brought about by their requirement to perform very extreme leg movements. To accurately evaluate such problems physicians would, ideally, like to be able to carry out MRI scans of ballet dancers whilst performing the splits. [that’s the dancers, not the physicians] And, impractical as […]

The Coriolis effect, trouser leg preference, and human rotation

Theoretical and practical investigations have shown that the ‘Coriolis effect’ (see video above) can substantially influence physical systems such as the trajectory of cannon balls and the rotation of meteorological phenomena. But very little research has addressed the issue of whether it might also affect human behaviour. For example, might the Coriolis effect affect which […]

Quantifying ballet dancers’ leg-lift angles

Very few scientific studies have formally investigated the angles to which ballet dancers lift their legs. But in 2009, a team from : the Dipartimento di Neuroscienze and Centro di Biomedicina Spaziale, Università degli Studi di Roma Tor Vergata, Roma, Italy, the Dipartimento di Fisiologia Neuromotoria, IRCCS Fondazione Santa Lucia, Roma, Italy, the Dipartimento di […]
