Accurately measuring how often young football players experience head impacts is critical for assessing and managing concussion risk, but the estimated number of impacts can vary widely depending on how the data are processed. Researchers investigated how different data-cleaning strategies affect estimates of head acceleration events recorded by instrumented mouthguards (iMGs) in youth tackle football. Fifty athletes ages 8–12 wore iMGs during games across one season, and the research team compared six approaches for filtering the raw sensor data, including time-windowing, proprietary classification algorithms, and video verification. Key findings: 🔹 Unfiltered data produced the highest head acceleration event rates. 🔹 The most rigorous approach (combining time-windowing, algorithm classification, and video verification) reduced estimated events from 67.75 to 0.70 per athlete exposure. 🔹 Data-cleaning choices had minimal effect on impact magnitude, including peak linear acceleration and peak rotational velocity. Standardized and transparent data-cleaning practices will be essential for generating reliable head impact exposure estimates and strengthening efforts to reduce concussion risk in youth sports.
