“…We are unaware of any other study that has reported this association in a similar population. While this finding is consistent with other studies in military recruits, 13,15,19,20 BMI remains an equivocal risk factor for any type of lower extremity injury in other studies of high school, recreational, and recruit populations. 23,33,38 A limitation of our finding may be that we used runners' self-report of height and body mass, which may not be comparable to studies that used direct measurement.…”

“…The physical activity of the runners provides an adequate stimulus to strengthen the neuromuscular and skeletal system, and thus, to reduce the risk of running injuries. As other studies show, the risk for running injuries is dependent on the weekly distance of running and previous injuries of the lower extremities [28]. Further studies are required to evaluate the risk factors of running injuries that might occur during the training for a marathon, thereby reducing the increasing number of running injuries.…”

Does marathon running cause acute lesions of the knee? Evaluation with magnetic resonance imaging

et al. 2006

An investigation was conducted into whether running a marathon causes acute alterations in menisci, cartilage, bone marrow, ligaments, or joint effusions, which could be evaluated by magnetic resonance imaging (MRI). Twenty-two non-professional marathon runners underwent MRI of the knee before and immediately after running a marathon. Lesions of menisci and cartilage (five-point scale), bone marrow, ligaments (three-point scale), joint effusion, and additional findings were evaluated and a total score was assessed. Before the marathon, grade 1 lesions of the menisci were found in eight runners, and grade 2 lesions in five runners. After the marathon, an upgrading from a meniscal lesion grade 1 to grade 2 was observed in one runner. Before the marathon, grade 1 cartilage lesions were found in three runners, and grade 2 lesions in one runner, all of which remained unchanged after the marathon. Before and after the marathon, unchanged bone marrow edema was present in three runners and unchanged anterior cruciate ligament lesions (grade 1) were seen in two runners. Joint effusions were present in 13 runners in the pre-run scans, slightly increased in four runners after the marathon, and newly occurred in one runner after the marathon. A total score comprising all knee lesions in each runner showed an increase after the marathon in two runners, whereas no runner showed an improvement of the radiological findings (Wilcoxon signed-rank test, P>0.05). The evaluation of lesions of the knee with MRI shows that marathon running does not cause severe, acute lesions of cartilage, ligaments, or bone marrow of the knee in well-trained runners. Only subtle changes, such as joint effusions or increased intrameniscal signal alterations, were imaged after running a marathon.

“…Several studies conclude that this approach leads to training volume being estimated wrongly (18), possibly because of subject recall bias, and timeconsuming self-reporting may demotivate the participant to continue in the study (13,35). Therefore, the methods used in previous studies to measure running volume by subjective methods (questionnaires, surveys, diaries) should be taken into careful consideration.…”

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.
