A Randomized Study of a Strength Training Program to Prevent Injuries in Runners of the New York City Marathon.

Researchers recruited over 700 first-time marathon runners before the New York City Marathon and split them into two groups: one that did a targeted 10-minute strength program three times a week for 12 weeks, and one that simply trained normally. The strength work focused on the quadriceps, hip abductors, and core muscles, areas commonly thought to help prevent running injuries. Despite this well-intentioned intervention, the rates of serious injuries that forced runners to drop out were nearly identical in both groups, around 7 percent.

The study also found no meaningful difference in finishing times between the two approaches. What this reveals is something clinically important: even though lower-limb overuse injuries are genuinely common in first-time marathoners, a straightforward self-directed strength program did not appear to move the needle on injury prevention.

If you're training for your first marathon, you've probably heard that strengthening your hips and thighs can help prevent injuries. This study looked at whether a simple 10-minute strengthening routine done three times a week actually made a difference for over 700 first-time marathoners.

The researchers found that runners who did the program got injured at about the same rate as those who didn't, and their race times were also very similar. This doesn't mean that strength work is useless or that you shouldn't train thoughtfully, but it does suggest that a basic program on its own isn't a magic solution to stopping the high rate of injuries that affect new marathoners.

The fact that nearly half of all runners reported some kind of injury shows how physically demanding marathon training really is.

This randomized trial offers a sobering reality check on the strength-for-prevention hypothesis that many of us lean on in practice. First-time marathoners experienced overuse injury rates of roughly 7 to 8 percent that resulted in noncompletion, and the risk ratio between the intervention and control groups was nearly one, with confidence intervals that included no meaningful difference.

The program itself was pragmatically designed: 10 minutes, three times weekly, targeting well-established anatomical areas. Yet the null finding persists even with reasonable compliance and a clear protocol.

The study population was large and reasonably representative, though injury was self-reported rather than objectively assessed, which leaves room for detection bias. What remains unresolved is whether more intensive supervision, longer training periods, or individualized prescription might yield different results, or whether the injury landscape in marathon running is simply more multifactorial than any single intervention can address.
