There is a need to ascertain if an association exists between excessive progression in weekly volume and development of running-related injuries (RRI). The purpose of this study was to investigate if GPS can be used to detect deleterious progression in weekly training volume among 60 novice runners included in a 10-week prospective study. All participants used GPS to quantify training volume while running. In case of injury, participants attended a clinical examination. The 13 runners who sustained injuries during follow-up had a significantly higher weekly progression in total training volume in the week before the injury origin (86% [95% confidence interval: 12.9-159.9], p = 0.026) compared with other weeks. Although not significant, participants with injuries had an increase in weekly training volume of 31.6% compared with a 22.1% increase among the healthy participants. The error of the GPS measurements in open landscape, forest, and urban area of volume was ≤6.2%. To conclude, no clinically relevant measurement errors of the GPS devices were found for training volume. Based on this, GPS has a potential to detect errors in training volume, which may be associated with development of RRI. Based on the results from the current study, increases in weekly training progression may become deleterious at a weekly increase above 30%, which is more than the 10% rule currently used as a guideline for correct progression in weekly volume by runners and coaches. Still, no clear evidence for safe progression of weekly volume exists. But it seems likely that some individuals may tolerate weekly progressions around 20-25%, at least for a short period of time.
需要确定每周跑量的过度增加是否与跑步相关损伤（RRI）的发生有关。本研究的目的是调查 GPS 是否可用于检测 60 名新手跑者在 10 周前瞻性研究中每周训练量的有害增加。所有参与者都使用 GPS 来量化跑步时的训练量。如果发生损伤，参与者会接受临床检查。在随访中受伤的 13 名跑者在受伤前一周的总训练量每周进展明显更高（86%[95%置信区间：12.9-159.9]，p = 0.026），与其他周相比。尽管不显著，但与健康参与者的 22.1%相比，受伤者每周训练量增加了 31.6%。在开阔地、森林和城市地区，GPS 测量的误差≤6.2%。总之，没有发现 GPS 设备在训练量方面存在临床相关的测量误差。基于此，GPS 有可能检测到训练量的错误，这可能与 RRI 的发生有关。基于当前研究的结果，每周训练进展的增加可能在每周增加超过 30%时变得有害，这超过了跑步者和教练目前作为每周训练量正确进展的指南的 10%规则。尽管如此，目前还没有关于每周跑量安全进展的明确证据。但似乎一些人可能至少在短时间内耐受每周 20-25%左右的进展。
