Development Of A Human Activity Recognition System For Ballet Tasks, Danica Hendry, Kevin Chai, Amity Campbell, Luke Hopper, Peter O'Sullivan, Leon Straker

Research outputs 2014 to 2021

Background Accurate and detailed measurement of a dancer’s training volume is a key requirement to understanding the relationship between a dancer’s pain and training volume. Currently, no system capable of quantifying a dancer’s training volume, with respect to specific movement activities, exists. The application of machine learning models to wearable sensor data for human activity recognition in sport has previously been applied to cricket, tennis and rugby. Thus, the purpose of this study was to develop a human activity recognition system using wearable sensor data to accurately identify key ballet movements (jumping and lifting the leg). Our primary objective was …

Kinematic Repeatability Analyses Of Multi-Segment Foot Motion In University-Level Ballet Dancers, Sarah Carter, Nahoko Sato, Luke Hopper

ECU Posters

Background:

Dancers are susceptible to overuse foot and ankle injuries, however there is a lack biomechanical studies examining foot mechanics to explain the causality of these injuries. The purpose of this study was to determine the intra and inter-assessor repeatability of a modified Rizzoli Foot Model (RFM) for ballet dancers.

Methods: Six university-level ballet dancers performed the following trials in randomized order, natural stance, turnout plié and stance, and two dynamic trials; turnout rise and flex-point-flex movement. A twelve-camera motion capture system were used to track fourteen reflective markers and one triad on the following segments: shank, entire foot, hindfoot, …

Comparison Of Body Composition, Neuromuscular Characteristics And Anaerobic Endurance Between Novice, Semi-Professional And Professional Ballet Dancers, Penelope Blanco Ochoa

Theses: Doctorates and Masters

Study 1 Comparison of body composition, neuromuscular characteristics and anaerobic endurance between novice, semi-professional and professional ballet dancers.
The purpose of this study was to compare selected physiological fitness parameters including: body composition, neuromuscular characteristics and aerobic endurance were significantly different between novice, semi-professional and professional ballet dancers. The secondary purpose was to establish which parameters were best discriminators between these dancers. Thirty-five classical ballet dancers (male: n =11 and female: n =24) divided into three different groups according to their dance skill level: novice (n=12) (age: 16.6 ± 1.5 y; height: 1.7 ± 0.1 m; weight: 58.0 ± 13.0 …
