The purpose of this study is to evaluate frequency and magnitude of head impacts in practice drills within a single youth football team. On-field head impact data were collected from 9 athletes (age = 11.1 ± 0.6 years, weight = 97.6 ± 12.2 lbs.) participating in an age and weight restricted youth football team for a single season. Head impact data were collected with the Head Impact Telemetry (HIT) System head acceleration measurement device. Video was recorded for all practices and games and video analysis was performed to verify head impacts and assign each impact to a specific drill. Drills were identified as: dummy/sled tackling, install, kickoff practice, Oklahoma, one-on-one, open field tackling, passing, position skill work, multiplayer tackle, tackling drill stations, and scrimmage. Mixed effects linear models were fitted and Wald tests were used to assess differences in head accelerations and number of impacts. There were significant differences in mean linear (p<0.0001) and rotational (p=0.003) acceleration and number of impacts per player (p<0.0001) among drills. Open field tackling drills had the highest median/95th percentile linear accelerations of 24.7g/96.4g and resulted in significantly higher mean head accelerations compared to several other drills. The multi-player tackling drill resulted in the highest head impact frequency of 6.6 impacts per player in a drill session. This study demonstrates the variability in head impact exposure among practice drills. These data, along with future research, may inform organizations on ways to structure their practice to limit high impact and high frequency drills and make sports safer for youth.
