Then,we investigated the activity profiles of 24 men’s lacrosse players [attack(AT): 5, midfield (MD): 13, defense (DF): 6] using a global positioning system(GPS) and a player acceleration apparatus to determine their movement andphysiological load.RESULTS: The study revealed that in 13matches (n = 302), top speed was significantly correlated with the 20 m dash,the 50 m dash, and the proagility shuttle (statistical significance: 0.05%).Distance, walk distance, and jog distance for the AT and DF groups weresignificantly greater than those of the MD group, but the MD group’s top speedand sprint distance were the highest. Multiple-comparison tests showed that topspeed, run distance, and sprint distance in the third and fourth quarters weresignificantly smaller than in the first quarter.CONCLUSIONS: The development of physicalqualities likely helps improve the in-game performance of lacrosse players.Particularly, an intermittent method congruent with exercise patterns in actualcompetitions should be used in training, and this study is useful in developingtraining programs for game tactics according to positional characteristics.
