“…The foregoing was confirmed by previous research [5], where attention was paid to the important role of the foot and that of the ankle in the proper shock absorption during a leap. The strong and negative correlation between the maxGRF and the angle in the knee joint at the moment of the first contact of the foot with the ground and the angle in the knee joint when the value of GRF was the highest (maxGRF).…”

The objective of the work was to determine biomechanical parameters influencing loads affecting the musculoskeletal system and shock absorption during the landing phase in Grand Jeté, Entrelacé and Ballonné. Methods: Motion kinematics measurements of the landing phase in GrandJeté, Entrelacé and Ballonné were carried out using the optical APAS system, and measurements of the GRF components-using Kistler platform. The research was carried out for three professional dancers. Kinematic and kinetic parameters of the landing were analysed. Results: The mean maximum GRF value in relation to the classical dancer amounted to 8.16 ± 1.37 N/BW. During landing, the joints of the lower limb are affected by external force moments of high values (ankle-3.04 ± 0.54 [Nm/BW], knee-7.56 ± 5.53 [Nm/BW], hip-10.97 ± 6.80 [Nm/BW]). The maximum value of the external force moments in the joint were strongly negatively correlated with the value of the angle in the hip joint at the moment of the first contact with the ground. It was noticed that the obtainment of maxGRF was preceded by a decrease in kinetic energy of approximately 50%. Conclusions: Factors affecting loads present in the musculoskeletal system during the shock absorption of a leap are: GRF values, the values of external force generated inside the joints and a change in the value of kinetic energy. The safe shock absorption after landing is influenced by properly positioned limb at the moment of the first contact, a greater range of movements in the joints and longer time from the moment of the first contact to the obtainment of maxGRF.

“…Deforth et al [ 24 ] demonstrated that the “scooped” foot with the high arch (Clarke angle > 55 deg) is characterised by the shorter arm of the force transmitted by the Achilles tendon. Because of this, during shock absorption after landing, precisely discussed by Gorwa et al [ 14 ], in relation to such a highly arched foot, muscular force generated by the muscles involved in shock absorption must be proportionally higher (to the shorter arm of the force). A similar muscular work will accompany the ascent to relevé.…”

“…In dance education, exercises increasing the muscular force of feet are introduced in forms 4–5 (at the age of 13 and 14) [ 28 ]. The aforesaid force must be sufficiently high to overcome the ground reaction force of grand jumps (grand jete, sissonne ouverte and grand pas de chat) generating a GRF of 4–9 BW [ 13 , 14 ] and responsible for difficult work in points [ 12 ]. In forms 7–9, the dance curriculum, in addition to grand jumps, includes pirouettes and intense work in points, introduced to enable the performance of grand fouette en tournant, cabriole or entrechat-six [ 28 ].…”

“…According to Liederbach, when performing the above-named element, the dancer generates force equivalent to the 10-fold value of the BW (body weight) [ 13 ]. The “ascent” on the top of points requires the work of lower limb muscles which, at the same time, must be both very strong and flexible [ 14 ]. Many authors agree that the introduction of the aforesaid exercises before the foot reaches its full functional maturity increases its susceptibility to injuries in the future [ 12 , 15 ].…”

“…For dancers, their feet are undoubtedly an important “link” in the mechanism of proper shock absorption [ 14 ]. Feet partly absorb impact forces [ 17 ] and co-adjust postural and stabilometric parameters [ 18 ].…”

This work aims to assess footprint parameters in a group of professional ballet dancers and to determine the correlation between the aforementioned parameters and lateralization, stabilometric parameters, pedobarographic parameters and work environment conditions. A group subjected to tests consisted of 44 elite professional ballet dancers and the reference group was composed of 44 students. The test of balance and thrust under feet involved 30 s-long free standing with open eyes on a podographic platform. The research-related analysis was concerned with footprint parameters (foot length and width, Clarke angle, and Weissflog index), stabilometric parameters (path length and ellipse field, mean value of the velocity and deflection of the displacement of the center of the foot pressure on the ground) and pedobarographic parameters (percentage thrust on the right, left foot as well as the front and rear part the foot). Statistically significant differences between the groups were observed in relation to the stabilometric parameters, the percentage pressure of the left forefoot and the right heel, as well as the value of the Clarke angle (p ≤ 0.05). The longitudinal arch of the foot and the width of the foot in ballet dancers are not dependent on the total and professional career duration and weekly training volume

Footwork is one of the basic features of flamenco dancing and is performed in traditional high-heeled shoes. The purpose of this study was to analyse the mechanical profile of flamenco dancing in terms of vertical ground reaction force, and knee joint kinematics of the supporting limb in footwork technique in order to understand causes which predispose injuries derived from the practice of flamenco dancing. The participant in our study was a professional female flamenco dancer (34 years, 58 kg, 1.65 m) who performed the ZAP 3 test, a sequence of single strikes of the feet performed continuously for 15 s. 3D lower extremity kinematic data were collected using a five-camera motion analysis system (Vicon; Oxford Metrics Ltd., Oxford, UK). Ground reaction forces were recorded using a Kistler force plate. Our analysis was based on 30 cycles of each lower limb consisting of 177 footwork steps. The vertical component of the ground reaction force did not reveal any significant differences between the left and the right limb. The most dynamic strike was provided by the heel (twice the participant's body weight). The mean angular displacement of the supporting limb’s knee was ~27°. Results reveal that these impacts could make the knee joint more prone to injuries.
