Injury Prevention Warm-Ups Cut ACL Injuries by About a Third in Female Team-Sport Athletes, Review of 13 Trials Finds
Exercise-based injury prevention programs lowered the risk of anterior cruciate ligament (ACL) tears in female team-sport athletes by about 38%. That is the finding of a new systematic review and meta-analysis published in Frontiers in Public Health.
What was studied
Girls and women who play team sports such as soccer, basketball and handball are known to have a high rate of ACL injuries. Many teams use neuromuscular warm-up programs that train balance, strength, jumping and landing technique to lower that risk. This review pooled 13 randomized controlled trials involving 13,675 female athletes to estimate how well these programs work, and whether training dose and adherence matter.
Key findings
- Overall injury risk fell by 35% (risk ratio 0.65).
- Lower-limb injuries fell by 33% (risk ratio 0.67).
- ACL injuries fell by 38% (risk ratio 0.62), and ankle injuries by 41% (risk ratio 0.59).
- Programs adding up to 51 to 120 minutes a week were linked with larger reductions than those giving 1 to 50 minutes a week.
- Trials where at least 75% of athletes stuck with the program showed clear protection, while trials with lower adherence showed little benefit.
What it means for people with knee pain
For young female athletes, parents and coaches, a structured warm-up done several times a week is one of the best-supported ways to protect the knee. The key is doing it consistently, not just occasionally. Ask a coach, athletic trainer or physical therapist about an established program your team can use.
Limitations
The authors rated the certainty of evidence for the main overall-injury result as low. The findings on training frequency, session length and adherence came from exploratory subgroup analyses, and the authors say they should not be read as firm thresholds. The trials also differed in sports, programs and how injuries were recorded.
Frequently asked questions
- Can exercise programs prevent ACL tears in female athletes?
- In this review of 13 randomized trials with 13,675 female team-sport athletes, exercise-based injury prevention programs lowered ACL injury risk by about 38% compared with usual training.
- How often should athletes do an injury prevention warm-up?
- Exploratory analyses in this review linked larger benefits with 4 to 5 sessions a week, sessions of 21 to 30 minutes, and 51 to 120 minutes a week in total. The authors say these are signals, not definitive rules.
- Does sticking with the program matter?
- Yes. Trials where at least 75% of athletes kept up with the program showed clear protection, while trials with lower adherence showed little evidence of benefit.
