The purpose of this study was to estimate the workloads accumulated by collegiate female soccer players during a competitive season and to compare the workloads of starters and substitutes. Data from 19 college soccer players (height: 1.58 ± 0.06 m; body mass: 61.57 ± 6.88 kg) were extracted from global positioning system (GPS)/heart rate (HR) monitoring sensors to quantify workload throughout the 2019 competitive season. Total distance, distance covered in four speed zones, accelerations, and time spent in five HR zones were examined as accumulated values for training sessions, matches, and the entire season. Repeated-measures ANOVA and Student's tests were used to determine the level of differences between starter and substitute workloads. Seasonal accumulated total distance ( < 0.001), sprints (≥19.00 km/h; < 0.001), and high-speed distance (≥15.00 km/h; = 0.005) were significantly greater for starters than substitutes. Accumulated training load ( = 0.08) and training load per minute played in matches ( = 0.08) did not differ between starters and substitutes. Substitutes had similar accumulated workload profiles during training sessions but differed in matches from starters. Coaches and practitioners should pursue strategies to monitor the differences in workload between starters and substitutes.
本研究的目的是估计大学女子足球运动员在一个竞争赛季中积累的工作量，并比较首发球员和替补球员的工作量。从全球定位系统（GPS）/心率（HR）监测传感器中提取了19名大学足球运动员的数据（身高：1.58±0.06米；体重：61.57±6.88千克），以量化整个2019年竞争赛季的工作量。将总距离、四个速度区域内覆盖的距离、加速度以及在五个心率区域内花费的时间作为训练课程、比赛和整个赛季的累计值进行检查。采用重复测量方差分析和学生t检验来确定首发球员和替补球员工作量之间的差异水平。首发球员的赛季累计总距离（P<0.001）、冲刺跑（≥19.00千米/小时；P<0.001）和高速距离（≥15.00千米/小时；P=0.005）显著高于替补球员。首发球员和替补球员之间的累计训练负荷（P=0.08）以及比赛中每分钟的训练负荷（P=0.08）没有差异。替补球员在训练课程中的累计工作量概况相似，但在比赛中与首发球员不同。教练和从业者应寻求策略来监测首发球员和替补球员之间工作量的差异。
