BACKGROUND: Managing athlete training volume is becoming increasing important, but there is little information regarding drill intensities and how drills affect each position. The purpose of this study was to identify drill intensities to determine the training volume for each position. METHODS: Global positioning system units were worn by 27 Division I female lacrosse athletes to gather training metrics, including: distance rate, maximum speed, distance, high-intensity distance (HID), sprint efforts, accelerations, decelerations, and sprint distance. All data was collected and uploaded into VX Sport software where it was trimmed and split for each drill completed in practice. Drills were categorized according to the five classifications: stickwork, small-sided games, conditioning, individual skill work (ISW), and team drills. All training metrics, except distance rate and maximum speed, were analyzed per minute spent in the drill to control for time. RESULTS: The drill database consisted of 99 days of training, which included three drills for stickwork, four drills for ISW, five drills for small-sided games, six drills for conditioning, and five drills for team drills. Analyses revealed a difference in the interaction of type of drill and player position for drill intensity metrics, p < .001. The conditioning drills required higher intensity work than all other drills for each metric analyzed, p < .001. ISW drills were less intense for distance rate, total distance, and accelerations than all other drill types, p = .000-.006. Stickwork was less intense than all other drill types for maximum speed and decelerations, p < .001. By position, attackers exhibited higher distance rate, speed, total distance, sprints, accelerations, and sprint distance than the other two positions, p = .000-.004. Midfielders exhibited greater sprint repetitions (p < .001) and sprint distance (p = .003) than defenders. CONCLUSIONS: Attackers showed higher intensities during training than the other two positions. Coaches can use this information to provide more specific training for each position and to manage the training volume of their athletes. Drill intensities can also be compared to game intensities to provide more specific training for games.
