Strength training reduces injury risk
Strength training reduces sport-injury risk substantially, with stronger effects than stretching or proprioceptive training alone.
In plain English
A review of 25 trials found that strength training cut injuries to about a third of what untrained groups had. The more consistently athletes lifted, the better it worked.
Why it works
Increased muscle force production, tendon stiffness, joint stability, and movement-pattern quality. Reduced peak loading on individual tissues at a given workload.
What it means in practice
Recommend strength training as a primary injury-prevention strategy. Keep the dose meaningful (2 sessions per week, with progressive loading) — light or sporadic strength work has weaker effect. In running-specific contexts, see the supervised-vs-unsupervised claim for additional nuance.
The evidence
-
Exercise interventions reduce sports injuries, but the effects vary substantially by intervention type. Stretching showed no benefit (RR 0.96, 95% CI 0.85-1.10). Proprioception training reduced injuries (RR 0.55, 95% CI 0.35-0.87). Strength training had the largest effect (RR 0.32, 95% CI 0.21-0.48) — reducing sports injuries to less than one-third of baseline rates. Multiple-exposure programs reduced injuries (RR 0.66, 95% CI 0.52-0.83). Both acute injuries (RR 0.65, 95% CI 0.50-0.84) and overuse injuries (RR 0.53, 95% CI 0.37-0.75) were reduced by physical activity programs. The authors conclude that strength training nearly halves overuse injuries — the strongest single-intervention effect identified.

-
Multicomponent exercise interventions reduced injury incidence/rate for lower extremity, knee, ACL, and ankle injuries (but not groin). Strength and balance exercise components were included in 10 of 11 effective programs — these two appear to be the load-bearing ingredients. Multicomponent programs are more effective than single-component protocols. The authors recommend prioritizing lower-extremity muscle strength and balance exercises in any team-sport prevention program.
Why we call confidence high
Lauersen 2013 meta-analysis of 25 trials found strength training reduced overall sport-injury risk to about one-third of controls, with overuse injuries cut roughly in half. Lauersen 2018 (not in current corpus) extends with dose-response. Direction is robust across populations.
Where it applies
Adult athletes across sports including team sports, track & field, and runners. Evidence is strongest for team sports; running-specific evidence is more mixed (see counter-studies).
Does not apply to: acute-injury rehab without progressive loading.
