Analysis of the physical development of athletes aged 8-10 in dance sports

The article presents a comparative analysis of physical development parameters by age and gender categories. The analysis was conducted among 8-10-year-old athletes from the dance sport of the sports club "Courage" in the city of Kharkiv and the standard of children of Ukraine. The conducted research proves the presence of a fairly high variation of the individual characteristics of the physical development of athletes. The circumference of the chest of male and female partners indicates the normal rate of development of the respiratory apparatus of the athletes under study. The analysis of height and body weight indicates an accelerated rate of maturation of the bodies of female partners of all studied age groups and the bodies of 9-year-old partners. The body weight and height parameters of the 8- and 10-year-old partners are within the limits of the standard for Ukrainian children of this age. The obtained data made it possible to plan training loads adequate to the individual parameters of the studied athletes in dance sports. The collected data will also be used in the selection of athletes for joint sports activities in dance sports.

A deep learning-based approach for emotional analysis of sports dance.

There is a phenomenon of attaching importance to technique and neglecting emotion in the training of sports dance (SP), which leads to the lack of integration between movement and emotion and seriously affects the training effect. Therefore, this article uses the Kinect 3D sensor to collect the video information of SP performers and obtains the pose estimation of SP performers by extracting the key feature points. The Arousal-Valence (AV) emotion model, based on the Fusion Neural Network model (FUSNN), is also combined with theoretical knowledge. It replaces long short term memory (LSTM) with gate recurrent unit (GRU), adds layer-normalization and layer-dropout, and reduces stack levels, and it is used to categorize SP performers' emotions. The experimental results show that the model proposed in this article can accurately detect the key points in the performance of SP performers' technical movements and has a high emotional recognition accuracy in the tasks of 4 categories and eight categories, reaching 72.3% and 47.8%, respectively. This study accurately detected the key points of SP performers in the presentation of technical movements and made a major contribution to the emotional recognition and relief of this group in the training process.

We intend for the first of these Special Issues, in particular, to serve as an intervention from hip hop stakeholders around the world, providing useful insights for those involved in this milestone moment, whether at a cultural community level or those working with intermediary institutions such as World Dance Sport Federation (WDSF) and the IOC.

Upper body posture in Latin American dancers: a quantitative cross-sectional study comparing different postures

BackgroundIn Latin American dance sport (LD), the shoulder girdle and the torso area are particularly stressed due to the dance style specific requirements. The aim of the study was to define differences in various dance specific upper body postures in Latin American dancers and to show gender-specific differences.MethodsThree dimensional back scans were performed in n = 49 dancers (28 f/21 m). Five typical trunk positions in Latin American dance (habitual standing and 4 dance specific positions, P1–P5) were compared with each other. Statistical differences were calculated using the Man-Whitney U test, Friedmann test, Conover-Iman test and a Bonferroni-Holm correction.ResultsSignificant gender differences were found in P2, P3 and P4 (p ≤ 0.01–0.001). In P5, the frontal trunk decline, the axis deviation, the standard deviation of the rotation, the kyphosis angle and the shoulder as well as the pelvic rotation were also significantly different. The comparison of the postures showed significant differences between postures 1–5 (p ≤ 0.01–0.001) in the males, (scapular height, right and left scapular angles and pelvic torsion). Similar results were observed for the female dancers, with only the parameters of frontal trunk decline with the lordosis angle as well as the right and left scapular angles being non-significant.ConclusionsThis study is an approach to better understand the involved muscular structures in LD. Performing LD changes the static parameters of the upper body statics. Further projects are needed to analyse the field of dance even more thoroughly.

ОСОБЛИВОСТІ ЕСТЕТИЧНО-ЦІННІСНОГО СПРИЙНЯТТЯ СУЧАСНОГО СПОРТИВНОГО БАЛЬНОГО ТАНЦЮ

In modern culture sports and art are among the main spheres of human life. Traditionally sports and art are presented as mutually exclusive sociocultural phenomena. In recent decades the situation has changed: the transformation of sports into a global phenomenon requires a scientific study of mutual influence of sports and politics, sports and economics, sports and international cooperation. Within the framework of this study, the question of relations between sports and art seems to be relevant. The article makes an attempt not only to consider the problem of interaction of two cultural phenomena: sport and art, but through the analysis of sports ballroom dance to raise the question of the existence of a certain «set» of visual and expressive means that allow considering dance sport not only as a sport, but also as an artistic one, a work of art with a certain aesthetic value and expressiveness. It is concluded, that dance sport, perhaps, more then any other technical and aesthetic sport is closed to art. Aesthetic expressiveness is inherent in all sports, but it manifests itself and functions in different ways. As for dance sport, the authors are convinced that the synthesis of sport and art in this sport has taken place. The development of dance sport will take place not by increasing the physical capabilities the level of technical skill, but by increasing the expressive capabilities of human corporeality, where is no limit. The multifaceted world, which passes through the prism of human perception and imagination, is transformed into the content of the dance image and is its choreographic reflection. Sports ballroom dance is a modern work of art, manifested through the dancer's mastery of his own body and the ability to convey all the accumulated experience to captivate the viewer and draw him into the world of beauty.

PHYSICAL ACTIVITY FORMATION BY MEANS OF DANCE SPORT

The article reveals the problems of special physical training of athletes-dancers. To master competitive programs, dancers need special physical training, which includes various parameters of locomotor skills and non-standard skills for performing complexly coordinated dance elements. Dance is not only a physical exercise, but also one of the forms of psychological relief. Unlike other physical exercises, dancing has no age restrictions. By examining the structure of dance movements, it can be stated that they have the dynamics of movement abilities, an emotional component, and the rhythmic content of music, which in general create a deep and interesting artistic image. High-speed dance movements performed with maximum amplitude require increased physical effort, strength, endurance, flexibility, and coordination of movements. Athletes- dancers of different age groups and skill levels need not only to improve, but also to maintain their physical form, which allows them to successfully perform at competitions. Therefore, when building the training process, it is worth paying attention to both the complex of general physical exercises and the complex of special exercises.
 Nowadays, it is impossible to achieve success in dance sport without a high level of development of these qualities since a decrease in their level in athletes-dancers leads to a deterioration in sports results.

The subjects of the study were 27 male seniors aged 65 or older living in G-si, Gyeongsangnam-do, and were classified into three groups: Dance Sports Group (n=10), Muscle Exercise Group (n=7), and Control Group (n=10). The experimental group was conducted three times a week for 16 weeks. As a result, in terms of functional body change in the elderly, the dance sports group showed more positive effects than the muscle exercise group and the control group in the 30-second chair stand test, 30-second push-up test, chair sitting and reaching test, backscratch test, and 2.44m up and high test. However, the exercise intervention effect did not appear in the two-minute step-by-step test. In the fall efficacy scale change test, the dance sports group showed better results than the control group. Therefore, in the case of the elderly, through regular physical activity and exercise, the overall physical health of the elderly can be maintained, such as maintaining muscle mass, reducing the prevalence of disease, and maintaining and enhancing functional fitness and fall efficacy. It is thought that the results of this study can be used as useful data for the elderly to form a successful aging process in the future as they maintain their health.

Body Composition and Nutritional Status of the Spanish National Breaking Team Aspiring to the Paris 2024 Olympic Games

Breaking is a sports dance modality that will debut for the first time at the Paris 2024 Olympic Games. This dance form combines street dance steps with acrobatics and athletic elements. It complies with gender equality, maintains aesthetic appeal, and is practised indoors. The objective of this study is to assess the characteristics of body composition and nutritional status of the athletes that make up the Breaking national team. This national team was recruited, and they underwent an analysis of body composition using bioimpedance measurement and a nutritional interview status with the completion of a survey on the frequency of the consumption of sports supplements and ergogenic aids. In addition, they completed a consumption questionnaire for a series of food groups with specified protein, lipid, and carbohydrate content. After that, parameters were analyzed in relation to their nutritional status during a complete medical examination at the Endocrinology and Nutrition Service of the Sports Medicine Center of CSD. A descriptive analysis of the results obtained was carried out to find the mean values of the variables analyzed. The analytical parameters described an adequate nutritional status, except for the mean capillary determination of 25-OH-vitamin D3, which was 24.2 ng/dL (SD: 10.3). Bone mineral density values were higher than those of the general population. This is the first time that a study of these characteristics has been carried out on Breakers, so it is highly relevant to increase knowledge in this area in order to conduct nutritional interventions aimed at improving the sports performance of these athletes.

Youth Sport Participation Trends Across Europe: Implications for Policy and Practice

ABSTRACT Purpose: Despite the known health and wellbeing benefits of taking part in sport for children and adolescents, it is reported that sports participation declines during adolescence. The purpose of this study was to explore current organized youth sport participation rates across Europe for both males and females and update current understanding. Method: Sport participation registration data was collected for 18 sports from 27 countries. In total, participation data was collected from over 5 million young people from Under 8s (U8s) to Under 18s (U18s). Differences in the participation rates between age categories were investigated using a generalized linear mixed effects model. Results: Overall, males were four times more likely to participate in organised youth sport than females’ participants, with this trend apparent across all age categories and across most sports. There was a significant decrease across sports in participation rates for males during adolescence from U14-U16 and U16-U18. There was a significant decrease in participation rates for females from U14-U16 for most sports except but an increase in participation rates from U16-U18 for 12 out of 18 sports. Soccer (1262%), wrestling (391%) and boxing (209%) were the sports that had greater male sport participation rates. In contrast, dance sports (86%) and volleyball (63%) had more female participants than males. This research shows male sports participation is significantly greater than female in youth sport across Europe. Conclusion: Furthermore, findings showed that for both male and female participants, participation rates increased from U8-U14 for the majority of sports followed by reduced participation rates during adolescence. Findings of this research can be used by national governing bodies and sporting organizations to inform youth sport participation initiatives.

TREINAMENTO DE FORÇA DO CORE NA MELHORIA DA COORDENAÇÃO MUSCULAR EM DANÇARINOS ESPORTIVOS

ABSTRACT Introduction: Dance sport is an emerging sport activity. The number of college students devoted to the study of dance is increasing. Basic dance sport skills are inherent to performance. Basic skills training requires dancers to have a certain degree of flexibility, endurance, speed, etc. Currently, we know that CORE strength training can improve the physical function of athletes, but studies are scarce as to its true impact on proprioceptive skills in dance sports. Objective: The purpose of this study was to examine the effect of strengthening the CORE on muscle coordination in sport dancers. This paper examines the relationship between core strength training and dance skills in athletes. Methods: Undergraduate sport dance students were randomly and voluntarily selected. These students undergo a 4-month training protocol in CORE strengthening. The effect of this experiment was evaluated with biomarker and kinetic data collected before and after the experiment. These data were worked out statistically and the results were discussed according to the literature. Results: After the CORE training protocol, the sport dance students had significant differences in physical tests(P<0.05). Conclusion: CORE training can promote physical stability, explosive power and muscle coordination in sport dancers. Level of evidence II; Training research - outcome investigation.

Kinematic analysis of sway motions of elite dance sport competitors

Purpose: This study aimed to identify the potential relationship between scores given by judges and kinematic variables used to characterise the sway movement in the Viennese waltz as performed by dance sport athletes. Methods: The study involved six world-class and six intermediate dance couples. The pairs were asked to perform three identical series of three natural spins of the figure in a Viennese waltz and were all recorded by camera as they danced to music. Six international adjudicators evaluated all trials of each couple from the viewpoint of the technical quality component based on the Absolute Judging System. A triaxial rotational angular velocity measurement device (gyroscope) was placed on the dorsal part of the pelvic girdle and on the posterior part of the thorax of every athlete. Results: The analysis of covariance showed that maximum angular rotation velocities of the thoracic spine in forward sway movements (in the transverse plane) in male dancers were strongly associated with the judging score obtained (F1,9 = 11.5; P < .05; ηp 2 = .05) regardless of the assignment to the given group. Conclusion: According to the study conducted and a comparison of elite and intermediate level athletes, the proposed method of assessing, presenting and reviewing the movement profile of the pelvic girdle and thoracic movement is likely to become useful for the overall assessment of movement technique, and also for carrying out quick and effective qualitative and quantitative biomechanical assessment of selected components of movement technique in dance sport. Keywords: Standard style, technique, ballroom dancing, Viennese waltz, absolute judging system.

INFLUÊNCIAS DO TREINAMENTO DE FORÇA DO CENTRO ABDOMINAL SOBRE A DANÇA ESPORTIVA

ABSTRACT Introduction: The essential characteristics of the unique fitness of sport dancing are composed of the athletes' skill, quality, and physical characteristics. All are directly affected by proper abdominal core strength training. Kick strength is an important variable for controlled balance in lower limb elevation. It is produced by the combined action of the pelvic girdle and thigh muscle groups, beginning at the abdominal core. Objective: This paper explores the effect of abdominal core strength training on the quality of kicking movement in dance sports work. Methods: Forty-six college students majoring in sport dance were randomly selected as volunteers for the research. Randomly divided into control and experimental group, they participated in the experiment for four weeks. The experimental group added a specific strength exercise for the abdominal core at each class, while the control group followed only with the routine exercises. Several indicators of the athletes were tested before and after the end of the experiment. The collected variables went through the statistical methodology and data analysis. Results: The experimental group members showed significantly higher kicks than those of the control group (P<0.05). The balance and stability scores in the experimental group were also significantly higher (P<0.05). Conclusion: Abdominal core strength training significantly affects the quality of lower limb lifting movements in sports dance practitioners and significantly affects the overall performance improvement of athletes.
