Foot Core Training to Prevent Running-Related Injuries: A Survival Analysis of a Single-Blind, Randomized Controlled Trial.

Researchers in this randomised controlled trial asked a straightforward question: can strengthening the small muscles in and around the foot help prevent the injuries that so often derail recreational runners? They enrolled 118 runners and gave one group an eight-week course of foot-focused exercises, then tracked both groups for a full year. The runners who did the foot training were about 2.4 times less likely to develop a running injury during that year compared to the control group. The link between foot strength, foot posture, and staying injury-free appeared meaningful, especially somewhere between four and eight months into the training.

While this is a solid and well-designed study, the authors themselves note that we still need to understand more about which runners might benefit most and exactly how these foot exercises protect against injury.

If you're a recreational runner dealing with injuries or worried about getting them, this research suggests that targeted foot exercises could make a real difference. In this study, runners who completed an eight-week program of foot-strengthening exercises and then continued training had notably fewer injuries over the next year compared to runners who didn't do this training.

What's encouraging is that the protection showed up fairly quickly, typically within the first few months. That said, the study followed runners for a year in controlled conditions, so how these results apply to your own running situation may depend on things like your current fitness, injury history, and how consistently you stick with the exercises.

The research team is clear that more work is needed to understand which runners benefit most and exactly why these foot exercises help.

This is a well-conducted randomised controlled trial examining foot core strengthening as a prevention strategy for running-related injury. The intervention consisted of an eight-week supervised protocol followed by remote supervision, with injury tracked over 12 months via weekly runner self-report.

The between-group difference was substantial from a relative risk perspective, with the control group showing a 2.42-fold higher injury rate. The biomechanical measures most associated with time to injury were Foot Posture Index and foot strength gains, though the correlation coefficients (0.41 and 0.45) suggest these explain a moderate portion of variance.

One useful observation is that protective effects appeared most evident in the four to eight month window, potentially informing the timing of intervention delivery. The abstract does not specify which injury types occurred in each group or whether subgroups of runners responded differently, so interpreting which runners in your caseload might benefit most remains uncertain.
