Background

This article sets the scene for a critique of the research underpinning 2 common clinical assumptions: (1) training workload is a key factor influencing sports injury risk, and (2) training workload can be manipulated to reduce injury risk. In this clinical commentary, we address why it is important for clinicians to critically evaluate the evidence behind research conclusions.

Clinical question

Has research been designed and conducted well enough to help clinicians answer the questions, "What is the relationship between training workload and sports injury risk?" and "Can the metrics based on training workload be used to decrease injury risk?"

Key results

In the past decade, many sports injury researchers have developed new measures of exposure, based on internal and external training workload, to study the relationship between training load and injury. Some of these metrics may have been embraced by researchers and clinicians because (1) they are apparently supported by the scientific literature, (2) they are simple to calculate and use (averages and their ratio), and (3) there is an apparent reasonable rationale/narrative to support using workload metrics. However, intentional or unintentional questionable research practices and overinterpretation of research results undermine the trustworthiness of research in the training load and sports injury field.

Clinical application

Clinicians should always aim to critically examine the credibility of the evidence behind a research conclusion before implementing research findings in practice. Something that initially looks promising and inviting might not be as revolutionary or useful as one first anticipated. J Orthop Sports Phys Ther 2020;50(10):574-576.
