<p>The use of microtechnologies in ice hockey is an emerging approach to the assessment of on-ice practice and match demands. This review aims to explore the use of wearable technologies to assess the locomotor and body external demands in ice hockey, provide position-specific normative data for practitioners and understand the in-depth insights these devices can measure. A scoping review was conducted to ensure methodological transparency and replicability. This design was selected to map the current literature and identify knowledge gaps regarding the integration of wearable technologies in ice hockey. The search strategy followed the specific framework to define eligibility criteria. Inclusion and exclusion criteria were applied to progressively focus on original research using wearable technologies that were used to quantify physical demands of ice hockey. A total of 22 articles were retained for the final analysis. Research predominantly focused on highly trained or elite male adult athletes, with a widespread 100-Hz inertial movement units application compared to Local Positioning System. Accelerations, decelerations, skating distance, PlayerLoad™, skating velocity zones distances, PlayerLoad·min⁻¹, Explosive Efforts and skating velocity were the variables most assessed in the literature. Physical demand metrics were grouped into volume, intensity, and density categories, with volume-based being the most frequently reported. Wearable technologies are increasingly implemented in ice hockey to monitor on-ice performance across training and competition. Future research should aim to assess the validity and reproducibility of the variables extensively used and contextualize data more deeply to enhance training design and optimize match preparation.</p>
