The aim of this study was to analyze the sprinting characteristics of female soccer players during matches using the global positioning system (GPS) device method combined with video analysis software. Eighteen Japanese collegiate female soccer players (age: 20.3 ± 1.3 years; height: 161.1 ± 5.7 cm; body mass: 55.6 ± 6.2 kg) were equipped with GPS (10 Hz), and sprinting (> 21 km/h) data during eight official matches was analyzed. Using video cameras, all games were filmed to record the situations when players were sprinting. The videos linked GPS data with the dedicated analysis software, and the data was extracted from the videos. We analyzed 790 samples of sprinting according to ball possession, play situation, and running direction for each playing position. The total number of sprints per match was 98.8 ± 11.2. The total number of sprints per match for each position was 26.7 ± 4.7 for forward, 30.4 ± 6.2 for side midfielder, 10.1 ± 3.9 for central midfielder, 18.6 ± 6.2 for side back, and 12.9 ± 2.1 for center back. The results of the chi-square test showed that the sprinting demonstrated during the game at each position depended on the situation. Our findings suggested that the characteristics of sprinting of Japanese collegiate female soccer players during a match differed depending on the situation and position the players faced.
