Hydrogels, owing to their superior softness, high water content, and excellent biocompatibility, are emerging as essential functional materials for next-generation wearable devices. In sports medicine and rehabilitation, hydrogel-based sensors enable real-time, noninvasive monitoring of multidimensional physiological and biomechanical parameters—including heart rate, respiration, sweat metabolites, and joint strain—thus providing new technological pathways for performance evaluation, injury risk prediction, and rehabilitation management. This review systematically summarizes recent progress in hydrogel applications for sports monitoring, injury prevention, and rehabilitation training, with a particular focus on stimulus-responsive hydrogels and key engineering strategies such as conductivity enhancement, pressure/strain sensing, self-healing mechanisms, stretchable electronics, and wireless integration. By highlighting advances in artificial intelligence–assisted data fusion, we further elucidate the potential of hydrogels for personalized training feedback and intelligent rehabilitation. Looking ahead, we outline future research directions in multifunctional system integration, interdisciplinary collaboration, and precision rehabilitation. Notably, anisotropic three-dimensional sensing hydrogels inspired by peripheral nerve structures offer new opportunities for complex motion recognition and personalized rehabilitation interventions. Overall, hydrogel-based wearable devices...
