(2024). Relationship between ankle dorsiflexion range of motion and sprinting and jumping ability in young athletes. Journal of Bodywork and Movement Therapies, 39, 43-49. https://doi.org/10.1016/j.jbmt.2024.02.0131360-85921532-9283http://hdl.handle.net/11268/12901Objectives: To investigate the relationship between predicted risk of injury based on the dichotomous classification of the weight-bearing lunge (WBL) test scores and variables related to jumping and sprinting ability in young athletes. Furthermore, to compare the impact of the classical dichotomous classification versus a more specific quartile subdivision of the WBL test scores on the explored variables. Design: Cross-sectional study. Participants: 125 healthy athletes (mean age 10.38 (SD = 2.28) years) were recruited. Main outcome measures: Ankle dorsiflexion was evaluated with the WBL test, jumping distance with the standing long jump (SLJ) test, and maximal running speed with the 14-m and 28-m sprint test. Results: Athletes with WBL test scores lower than 10 cm exhibited significantly poorer results for the SLJ test as well as lower 14-m and 28-m sprint times than those with WBL test scores higher than 10 cm (p < 0.05). Likewise, when WBL test scores were subdivided by quartiles, a positive trend between range of motion and improved performance was shown. Conclusions: Reduced ankle dorsiflexion mobility may affect sprinting and jumping ability in young athletes. In addition, a more detailed classification of ankle restriction by quartiles is proposed in this study in order to prevent injury and enhance athletic performance.engAttribution-NonCommercial 4.0 Internacionalhttps://creativecommons.org/licenses/by-nc/4.0/journal article10.1016/j.jbmt.2024.02.013open accessAtletaJovenEntrenamientoGoal 3: Ensure healthy lives and promote well-being for all at all ages
