Comparison of Match External Loads across a Men's and Women's Lacrosse Season.

The purpose of this study was to compare external workloads between collegiate men's (MLAX) and women's lacrosse (WLAX) matches and examine positional differences across the season. Athletes (MLAX: = 10; WLAX: = 13) wore a global positional system device during all matches. External load metrics included in the analysis were total distance (TD), sprint distance (SD), accelerations (>3 m/s), sprint efforts, player load per minute (PL/min), top speed, and distances spent in various speed zones. WLAX had higher TD ( = 0.001), SD ( < 0.001), distances in SZs 2-5 ( < 0.001), PL ( < 0.001), and sprint efforts ( < 0.001) compared to MLAX. However, MLAX performed more acceleration ( < 0.001) and deceleration ( < 0.001) efforts. WLAX midfielders (M) and defenders (D) reached higher top speeds and performed more accelerations than attackers ( < 0.001). Midfielders covered the greatest distance at high speeds ( = 0.011) and the smallest distance at low speeds (<0.001) for WLAX. For MLAX, midfielders performed the highest SDs, top speeds, accelerations, decelerations, and distances in higher speed zones ( < 0.001) compared to attackers and defenders. Results indicate that there are significant gender and positional differences in external workload demands during match play, specifically for volume- and intensity-derived workload parameters, between men's and women's lacrosse. Therefore, sports performance coaches should create gender- and position-specific conditioning programs to prepare athletes for match demands.
