“…It is also linked with the stability of the working lower limb (Golomer et al, 2009b). Imura et al (2008) examined a group of dancers performing the fouette turn on the force plate in soft ballet shoes. The authors considered that the magnitudes of the moment of ground reaction forces, which could help to assess the maintenance of the COP, might have changed if dancers would turn the fouette wearing hard ballet shoes.…”

“…The aim of this study was to evaluate static and dynamic balance related to rotational movement en pointe and en demi pointe in ballet dance students. Research hypotheses, based on the current knowledge (Imura et al, 2008;Perrin et al, 2002), assumed that dancers static balance can be deteriorated with eye closure and dynamic balance during rotational movement can worsen when the base of support was decreased. That has an implication in terms of training programs modifications such as introducing proprioceptive and individual balance training, to avoid the risk of injury related to worse balance parameters.…”

The aim of this study was to assess static and dynamic balance related to rotational movements en pointe and en demi pointe in ballet dance students. The study group consisted of 13 people -students of one of the ballet schools in Poland: 9 dancers from the junior class (14 years old) and 4 dancers form the senior class (18 years old). For the purpose of statistical analysis, the group was divided into 4 subgroups. Each person took part in a static balance test which included a 30s trial with eyes opened and 30s trial with eyes closed. The examination of dynamic balance related to rotational movements was also performed to compare movements en pointe vs. movements en demi pointe. Analyses were performed using the Kistler 9286BA platforms, which are the module of BTS Smart DX 7000. Data processing was performed with the use of BTS Sway and Statistica 10. Accepted level of significance was α = 0.05. Increase in the following center of pressure parameters was observed in the examination with eyes closed: maximal radius, longitudinal range, equivalent area and velocity. Participants from the senior class did not show these differences. There were no differences found between movements en demi pointe in comparison with movements en pointe. Static balance deteriorated with eyes closed in the entire examined group. Participants from the senior class showed more stable parameters of static balance. There were no differences in dynamic balance when the base of support was decreased.

Feed related costs are the main drivers of profitability of commercial poultry farms, and good nutrition is mainly responsible for the exceptional growth rate responses of current poultry species. So far, most research on the poultry feeding behaviour addresses the productivity indices and birds' physiological responses, but few studies have considered the biomechanical characteristics involved in this process. This paper aims to review biomechanical issues related to feed behaviour of domestic chickens to address some issues related to the feed used in commercial broiler chicken production, considering feed particle size, physical form and the impact of feeders during feeding. It is believed that the biomechanical evaluation might suggest a new way for feed processing to meet the natural feeding behaviour of the birds.

. Fouetté turns are repeated pirouettes which begin as a normal pirouette en dehors but include a movement that allows the rotational momentum lost to friction to be regained once each revolution. The purpose of this study was to investigate on orientation density of head/trunk to the front with and without music to which dancers perform the Fouette turn in time. 10 female dancers(21.0±1.4 years old, height; 165.3±3.9 cm, weight: 50.5±5.7 kg) who are the students of S University participated in this study. It took shorter time to perform one revolution of fouette turn with music (930 ms) than without music (961 ms), which reason may be the shorter time of phase 2 in which the rotational momentum is not produced but lost to fiction. Orientation density of trunk to the front was smaller with music (.176) than without music (.196), while the one of head had not significant difference between with and without music. And the path length of marker on 2 nd left metatarsal bone during one revolution was smaller with music (35.7 cm) than without music (40.2 cm) but the difference was not statistically significant (p=.267).
