The aim of this study was to determine the acceleration (≥2ms) and deceleration (≤-2ms) profiles of elite female soccer players during competitive matches.
Single cohort, observational study.
An Optical Player Tracking system was used to determine acceleration (≥2ms) and deceleration (≤-2ms) variables for twelve elite female players across seven competitive matches.
In total, players performed 423 (±126) accelerations and 430 (±125) decelerations per match. It was shown that the number of accelerations (p=0.003-0.034, partial η=0.229-321) and decelerations (p=0.012-0.031, partial η=0.233-275) at different intensities (based on the start and final velocity) varied according to player position. Mean and maximum distance per effort was 1-4m and 2-8m, respectively, and differed between each intensity category (p<0.001, partial η=0.753-0.908). The mean time between efforts was 14s for both accelerations (±5s) and decelerations (±4s) and fluctuated between 15min time periods (p<0.001, partial η=0.148-0.206).
The acceleration and deceleration profiles varied according to player position and time period of the match. The results of this study can be used to design match-specific acceleration and deceleration drills to enhance change of speed ability.
本研究旨在确定精英女子足球运动员在比赛中的加速（≥2m/s²）和减速（≤-2m/s²）情况。
单队列观察性研究。
使用光学球员追踪系统，确定12名精英女球员在7场比赛中的加速（≥2m/s²）和减速（≤-2m/s²）变量。
球员每场比赛平均进行423（±126）次加速和430（±125）次减速。结果表明，不同强度（基于起始和最终速度）下的加速次数（p=0.003-0.034，偏η=0.229-0.321）和减速次数（p=0.012-0.031，偏η=0.233-0.275）因球员位置而异。每次加速和减速的平均距离和最大距离分别为1-4米和2-8米，且在各强度类别之间存在差异（p<0.001，偏η=0.753-0.908）。加速和减速之间的平均时间间隔均为14秒（±5秒），且在15分钟时间段内波动（p<0.001，偏η=0.148-0.206）。
加速和减速情况因球员位置和比赛时间段而异。本研究结果可用于设计特定比赛的加速和减速训练，以提高速度变化能力。
