Exploring the link between shoulder external rotation range and Y-Balance Test performance in young cricketers

Aim. The aim of this study is to investigate the relationship between shoulder external rotation range of motion (ER ROM) and performance on the Y-Balance Test in young cricketers. Specifically, the study seeks to determine whether greater shoulder external rotation is associated with improved dynamic balance, which is crucial for cricket performance, particularly in movements like throwing and bowling. The research aims to provide insights that may help guide training and injury prevention strategies in young athletes. Methods. A total of 50 cricketers were selected based on defined inclusion and exclusion criteria. The active ROM of shoulder external rotation on the dominant side was measured using a goniometer. Participants performed the three directional movements of the YBT using non-instrumented floor markings. Findings. The study analyzed the relationship between Y-Balance Test (YBT) performance and shoulder external rotation range of motion (ROM) in young cricketers. The mean medial component of YBT was 80.42, with a weak positive correlation (r = 0.048, p = 0.82). The superolateral component had a mean of 59.18 and a weak negative correlation (r = −0.284, p = 0.16). The inferolateral component showed a moderate negative correlation (r = −0.365, p = 0.073) with a mean of 74.98. Shoulder external rotation ROM had a mean of 88.12, but no significant correlations were found. Conclusion. Among the three YBT components, only the medial component demonstrates a positive correlation with shoulder external rotation on both the dominant and non-dominant sides. Conversely, the superolateral and inferolateral components exhibit a negative correlation.
