Strong toe flexors are particularly crucial for efficient propulsion during running and jumping. Therefore, strengthening the feet has gained increased attention in the general population, as well as among athletes and dancers. However, accurately assessing foot muscle strength remains challenging. This study investigated the within- and between-session reliability of toe flexor maximal voluntary isometric contraction (MVIC) using a custom-made dynamometer. <b>Method:</b> Twenty-five vocational ballet students (23 females and two males; age: 16.48 ± 1.2 years; mass: 53.06 ± 8.84 kg; height: 167.14 ± 6.4 cm; forefoot length: 6.55 ± 0.44 cm) participated in two data collection sessions 48 to 72 hours apart with three trials each session.

Analysis was conducted using principles of Grounded Theory. <b>Results</b>: Participants mentioned that being a healthy dancer was based on three main concepts: (1) achieving a dynamic balance of load through self-implemented strategies, (2) receiving support from their team and (3) navigating the aspects inherent to the professional ballet context. Dancers had to maintain a dynamic balance where they would adapt their load according to a constant assessment of their state (ie, pain, fatigue) and situations (ie, casting, opportunities, career). This dynamic balance was impacted by the support dancers receive from their entourage. They needed to establish relationships built on trust to ensure efficient communication and collaboration. Once established, the dancers' entourage contributed to their assessment and the load adaptation strategies. The assessment and adaptation of load by dancers and the support provided were also influenced by contextual elements of ballet culture, including time and financial resources. <b>Conclusion</b>: To provide comprehensive care for dancers and maintain a dynamic balance, it is essential to empower dancers in their self-strategies through education and creating a positive work environment where open communication is encouraged.</p>","PeriodicalId":46421,"journal":{"name":"Journal of Dance Medicine & Science","volume":" ","pages":"407-417"},"PeriodicalIF":1.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145477266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
