Study on the effect of blood flow restriction training combined with IASTAM on ankle strength and function intervention in athletes with chronic ankle instability in sport dance events.

BACKGROUND: Athletes engaged in sports dance frequently encounter the potential for ankle injuries and instability, factors that may contribute to diminished training efficacy, compromised athletic performance, prolonged recuperation, and heightened susceptibility to recurring injuries. OBJECTIVE: The objective of this study was to investigate the impact of an exercise intervention (comprising blood flow restriction training combined with low-load ankle muscle strength training and balance training) as well as instrument-assisted soft tissue mobilization (IASTM) on the foot and ankle function, strength, and range of motion in sports dance athletes exhibiting ankle instability (CAI). METHODS: Thirty participants exhibiting ankle instability, restriction, or discomfort were recruited and randomly assigned to two groups: the Test group (comprising blood flow restriction training combined with IASTM, n = 15) and the traditional ankle strength training group (n = 15). The intervention spanned 4 weeks, with one session per week. Assessment of the Cumberland Ankle Instability Tool (CAIT), Foot and Ankle Ability Measure (FAAM), and ankle range of motion occurred at three time points: pre-intervention, immediately following the initial intervention, and after 4 weeks of intervention. Ankle strength testing was conducted solely before and after the intervention for comparative analysis. RESULTS: There were no significant variances in baseline characteristics between the two intervention groups. In terms of CAIT scores, both groups exhibited notably higher scores following the initial intervention and after 4 weeks of intervention compared to pre-intervention (P < 0.05). The Test group displayed higher CAIT scores than the control group, signifying a more pronounced enhancement in ankle stability among patients in the Test group. Concerning FAAM scores, both groups significantly enhanced ankle function in CAI patients (P < 0.05), with the Test group demonstrating notably higher FAAM-SPORT scores than the control group (P < 0.05), indicating superior restoration of athletic capability in the Test group. As for improvements in ankle range of motion, both groups demonstrated significant enhancements compared to pre-intervention (P < 0.05). The Test group exhibited significantly superior improvements in dorsiflexion, eversion, and inversion range of motion compared to the control group (P < 0.05), while the control group did not exhibit significant enhancements in plantarflexion and eversion range of motion (P > 0.05). Both groups displayed enhanced ankle strength in CAI patients following the intervention (P < 0.05), with the Test group manifesting notably higher dorsiflexion and inversion strength than the control group (P < 0.05). CONCLUSION: Both blood flow restriction training combined with IASTM and traditional ankle strength and stability training have shown significant improvements in stability, function, strength, and range of motion in CAI patients. Furthermore, the Test group exhibits superior efficacy in ankle stability, daily functional movement, dorsiflexion, and eversion range of motion compared to the control group.

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.

Frequent Sports Dance May Serve as a Protective Factor for Depression Among College Students: A Real-World Data Analysis in China.

PURPOSE: This study aims to investigate the role of frequent sports dance in preventing mental disorders, including anxiety and depression, among college students using real-world data, and to further analyze potential risk factors associated with anxiety and depression. METHODS: We investigated 921 college students from eight universities in China. A survey was completed by 901 students and they were included in the analysis. The anxiety score was evaluated by the Generalized Anxiety Disorder 7-item (GAD-7) scale and the depression score was evaluated by the Patient Health Questionnaire-9 (PHQ-9). Subgroup comparisons were performed among frequent sports dance students and non-frequent sports dance students. RESULTS: Of all the students, 9.98% had moderate-to-severe anxiety and 14.65% students suffered from moderate-to-severe depression. Compared with non-frequent sports dance students, frequent sports dance students had significantly lower depression scores (P=0.04). According to the multiple logistic regression models, when potential confounding factors were all adjusted, frequent sports dance was also significantly associated with less depression (OR=0.55, 95% CI: 0.36-0.84, P<0.01). We also found that higher college grade levels (P<0.01), non-physical education students (P=0.02), higher body mass index (P=0.02), lower exercise frequency per week (P<0.01), addiction to drinking (P=0.02), and previous diagnosis of anxiety or depression in hospital (P<0.01) were significantly associated with more anxiety; higher college grade levels (P<0.01), addiction to drinking (P<0.01), preference for eating fried food (P=0.02), soda as the main source of drinking water (P=0.01), and previous diagnosis of anxiety or depression (P=0.03) were significantly associated with more depression, while higher exercise frequency per week (P<0.01), only-child status (P<0.01), and preference for eating vegetables (P=0.02) were significantly associated with less depression. CONCLUSION: Anxiety and depression are common among college students. Frequent sports dance may serve as a protective factor for preventing depression and it can be recommended for college students.

Special Considerations for Growing Dancers.

Care of young dancers requires a unique approach during a critical time of growth and development. Young dancers' well-being depends on factors including sleep, mental health, growth-associated musculoskeletal imbalances, and nutrition. Puberty is a particularly important time for young dancers. It coincides with an increased commitment to their art form and physical/psychosocial changes. It is imperative for practitioners to understand these various factors in order to optimize young dancers' health and allow them to safely train and perform.

The aim aimed to conduct a research on the impact of modern sports dance on college students' mental health. This study selected 200 non-sports major students from a school in a certain province that did not offer sports dance as the research subjects. Secondly, 100 students were randomly selected from another college in the province to take sports dance courses as an experimental group for a three-month study and training of sports dance courses. Randomly select 100 people from schools that have never offered sports dance as a control group, the control group did not take sports dance courses, but only underwent routine learning and exercise. The experimental period was three months, and the experimental group and the control group were measured with two mental health self-assessment scales before and after the experiment, after statistical analysis, the conclusion was drawn as follows: (1) Sports dance has a promoting effect on the mental health level of college students. (2) Sports dance can improve the physiological condition of college students. (3) Sports dance can improve the interpersonal skills of college students. (4) Sports dance can effectively resist the psychological barriers of college students. Sports dance is a very beneficial physical activity for the mental health of college students, by conducting sports dance teaching, students' social communication ability can be improved, self-confidence can be cultivated, and psychological problems can be prevented. Sports dance teaching, from a subconscious level, increases students' ability to withstand stress and is an effective way to improve their mental health level. This study could also helped to educational institutions to give importance on sports modern dance to increase psychological health of students.(AU)

Cultivation and Differential Development of Mental Health and Subjective Happiness of Seniors Based on Sports Dance / Cultivo y Desarrollo Diferencial de la Salud Mental y Felicidad Subjetiva de las Personas Mayores Basado en la Danza Deportiva

Age-friendly sports can effectively alleviate the pressure of population aging on economy and society. Many studies have discussed the motives, current states, and favorite sports of seniors participating in physical exercise. However, there is little report on the evaluation of the health of seniors in sports dance, or the gradual cultivation of mental health and subjective happiness of seniors. Therefore, this paper explores the cultivation and differential development of mental health and subjective happiness of seniors based on sports dance. Firstly, a scientific evaluation index system (EIS) was constructed for the health of seniors in sports dance. Next, a matter-element extension model was established, and the detection methods were developed for the evaluation criteria. Finally, the flow of index weighting was explained. Through experiments, the authors analyzed the difference among seniors in mental health improvement and subjective happiness cultivation under the intervention of sports dance. The research results provide a reference for how the mental health and subjective happiness of seniors are affected by the scientific training and benign development of sports dance, as well as long-term exercise of sports dance.(AU)
