不同學習方法評估街舞基礎律動技巧

Abstract

緒論：街舞為現在廣為人知的舞蹈，不論是電視節目、社團活動都可以看到街舞身影。因應疫情，線上學習為近幾年活絡的趨勢，舞蹈課程也不例外。在學習街舞的課程中，基礎律動無疑是最重要的，如果能透過隨手可得的影片，將舞蹈學習最大化，不但在練習其他街舞動作時能更順暢，也能讓不敢進入舞蹈教室的人，先自行練習，降低對學習舞蹈的恐懼感。目的：比較實際教學及影片教學介入後，各組學習的成果、兩組間及性別上的動作差異。方法：本研究招募十五名具有運動習慣的男性女性，隨機分派至實際教學組及影片學習組，以重複量數二因子進行統計分析，來觀察兩組間學習前後的質心垂直位移、矢狀面上的髖、膝、踝關節彎曲角度及胸口移動位置的變化。結果：在不同教學方法的介入後，所呈現出來髖關節活動度皆有差異；兩組學習後胸口前後位移也有明顯的變大；其餘皆無顯著差異。在性別方面，除了髖關節男性在學習後活動度變大，其餘數值在女性較大。結論：影片教學在髖關節活動度有顯著提升，但是運用不正確的方式增加髖關節活動度，這種狀態在男性的資料上也是，可能為運動習慣所造成的。未來在設計影片內容或教學時，可多加注意這髖關節的教學細節，來達成更好的動作準確性。

Introduction: Street dance has gained significant popularity in recent times, with its presence in TV shows and clubs becoming commonplace. The COVID-19 pandemic has prompted a surge in online learning, including street dance classes. Developing a strong foundation in rhythm is essential for mastering street dance, and if video tutorials can effectively facilitate skill acquisition,they could serve as a valuable resource for practicing various dance techniques and alleviating the apprehension associated with attending in-person dance classes. Purpose: This study aims to compare the effectiveness of learning rhythm through watching basic dance videos versus receiving instruction from a teacher, while also exploring potential differences in rhythm learning between genders. Method: Fifteen participants with regular physical activity but no prior dance experience were recruited for this study. The participants were randomly assigned to two groups: one group learned through video tutorials, while the other received guidance from a dance teacher. Biomechanical parameters were measured before and after the learning sessions. These parameters included the range of motion (ROM) of the hip, knee, and ankle joints, as well as the movement of the center of mass and chest during rhythm-based movements. Statistical analysis was conducted using repeated-measures ANOVA. Results: The two learning methods yielded significant differences in hip ROM, with participants who watched videos exhibiting a wider range of motion. However, both learning methods resulted in a significant increase in chest displacement. When considering gender differences, except for hip ROM, females generally exhibited greater values than males across the measured parameters. Conclusion: The group that watched the videos showed an increased hip range of motion (ROM), but they tended to perform the movements incorrectly. This observation was consistent among males as well. It is possible that this discrepancy is due to their exercise habits. When teaching others, it is important to prioritize focusing on the hip joint to enhance the quality of movement.
