Athlete monitoring via wearable technology is often used in soccer athletes. Although researchers have tracked global outcomes across soccer seasons, little information exists on athlete loads during individual practice drills. Understanding these demands is important for athletic trainers in making decisions about return to play.
To provide descriptive information on total distance, total player load (PL), total distance per minute, and PL per minute for practice drill structures and game play by player position among female soccer athletes across a competitive season.
Retrospective observational study.
National Collegiate Athletic Association Division I university.
A total of 32 female collegiate soccer players (age = 20 ± 1 years, height = 168.75 ± 4.28 cm).
INTERVENTION(S): Athletes wore a single global positioning system and triaxial accelerometer unit during all practices and games in a single soccer season. Individual practice drills were labeled by the team's strength and conditioning coach and binned into physical, technical and tactical skills and large- and small-sided competition drill structures.
MAIN OUTCOME MEASURE(S): Descriptive analyses were used to assess the median total distance, total PL, total distance per minute, and PL per minute by drill structure and player position (defender, forward or striker, and midfielder) during practices and games.
Large- and small-sided competition drills imposed the greatest percentage of workload across all measures for each position (approximately 20% of total practice), followed by physical drills. When comparing technical and tactical skills drills, we found that technical skills drills required athletes to cover a greater distance (approximately 17% for technical skills and 15% for tactical skills), and tactical skills drills required higher play intensity during practices across all positions (approximately 18% for technical skills and 13% for tactical skills). Defenders had the highest median PL outcomes of all positions during practices.
Different practice drill types imposed various levels of demands, which simulated game play, on female soccer athletes. Athletic trainers and other clinicians may use this information in formulating objective return-to-play guidelines for injured collegiate women's soccer players.
可穿戴技术在足球运动员中常被用于运动员监测。尽管研究人员已经追踪了整个足球赛季的全球结果，但关于个别训练练习中运动员的负荷却知之甚少。了解这些需求对于运动训练员在决定运动员复出时做出决策非常重要。
提供关于女足球运动员在整个竞争赛季中，按球员位置分类的练习 drills 结构和比赛中的总距离、总球员负荷 (PL)、每分钟总距离和每分钟 PL 的描述性信息。
回顾性观察性研究。
美国全国大学体育协会一级大学。
共 32 名女大学生足球运动员（年龄=20±1 岁，身高=168.75±4.28cm）。
在一个足球赛季中，所有的练习和比赛中，运动员都穿着单个全球定位系统和三轴加速度计装置。个别练习 drills 由球队的力量和体能教练标记，并分为体能、技术和战术技能以及大小场地比赛 drill 结构。
使用描述性分析评估每个位置（后卫、前锋或前锋和中场球员）在练习和比赛中，按 drill 结构和球员位置分类的总距离、总 PL、每分钟总距离和每分钟 PL 的中位数。
大小场地比赛 drill 在所有测量中对每个位置的工作量的占比最大（大约占总练习的 20%），其次是体能 drills。当比较技术和战术技能 drills 时，我们发现技术技能 drills 要求运动员覆盖更大的距离（大约 17%是技术技能，15%是战术技能），而战术技能 drills 在所有位置的练习中需要更高的运动强度（大约 18%是技术技能，13%是战术技能）。在练习中，后卫的 PL 中位数结果在所有位置中最高。
不同的练习 drill 类型对女足球运动员施加了不同水平的要求，这些要求模拟了比赛。运动训练员和其他临床医生可以使用这些信息制定受伤女大学生足球运动员客观复出的指导方针。
