Biomechanical Comparison of “Dead” and “New” Pointe Shoe in Female Professional Ballet Dancers

ABSTRACT

Purpose: Available research on pointe shoes often compare pointe shoes to other dance footwear, however there is a lack of studies comparing dancers’ biomechanics when using “new” pointe shoes and pointe shoes that have worn down, “dead”. The aim of this study was to examine the biomechanical differences exhibited by professional ballet dancers while performing relevé, sous-sus, and pirouette in “dead” and “new” pointe shoes. Methods: Thirteen female (20.9 ± 1.9 years old) professional ballet dancers were asked to perform three trials of relevé, sous-sus, and pirouette in “new” pointe shoes and “dead” pointe shoes. Center of pressure sway area and ground reaction forces in the anterior-posterior, medial-lateral, and vertical directions were recorded using one AMTI force plate. Results: The “dead” pointe shoe condition had significantly higher sway area during relevé, sous-sus, and single pirouette (103 ± 95 mm2; 256 ± 133 mm2; 178 ±129 mm2, respectively) than the “new” pointe shoe condition (50 ± 65 mm2; 110 ± 64 mm2; 77 ± 39 mm2, respectively),  p-value < 0.05. In addition, peak ground reaction force in the anterior-posterior direction during relevé movement was higher in “new” pointe shoes (35 ± 6% body weight) than in “dead” pointe shoes (32 ± 6% body weight), p-value = 0.019. No significant differences were observed for the other dependent variables. Conclusions: A larger sway area was observed in “dead” pointe shoes compared to “new” pointe shoes, which indicates that the participant had less balance in the “dead” pointe shoes than in the “new” pointe shoes. The larger sway area in “dead” pointe shoes may indicate that decrease in shoe integrity may contribute to decrease in the support and stability of the pointe shoe while the ballet dancer maintains the ‘en pointe’ position. Moreover, higher forces in the anterior direction state that the dancers can apply more forces in the “new” point shoe. Application in sport: These results can educate ballet teachers and ballet dancers about the mechanical changes in “dead” pointe shoes, which may lead to injury and reduce in performance. Furthermore, these results may lead to enhancements in footwear design.

In the final year of his doctoral coursework at the United States Sports Academy (USSA), Edward currently works as a counselor at Pascagoula High School in Pascagoula, Mississippi. Having run and coached the Nicholls State University cross country team, he has enjoyed working with adolescents in athletics and academics for the past 42 years. In sports, amateurism has always interested Edward; so the connection to Olympism turned into an obvious course of study making his choice to attend USSA a great decision. Son to Edward Senior and Janice Burgo, Edward was the oldest of five children and contributes his drive and passion to his parents, and gives great credit to them for encouragement to continue on the path of education. Special thanks given to Edward Douglas White Catholic High School for the education that has led to Edward’s success.

Coubertin’s Influence on Education, Sports, and Physical Education

ABSTRACT
Pierre de Coubertin, father of the modern Olympic Games, traveled to England and the United States with the hope of changing the educational system in France. His first-hand observance of the effect that sport had on education helped to create his educational philosophy. In his efforts to create an environment of learning for students that would bring a moral and healthy life to the classroom, he changed the world. With Coubertin’s vision and drive, he was able to create an event that incorporated education, art, and a moral character in the design. The growth of the Olympic Games has touched many nations leaving a legacy in host cities that will remind people for generations of the peaceful message the event brings.
