What is an acceptable percent asymmetry for athletes?
Based on our literature review the acceptable percent difference between lower body limbs is 10-15%. Anything below this value is also fine, we have seen some high level athletes have asymmetries close to 0%. As well as some high level athletes have asymmetries closer to 10%.
It should be acknowledged that asymmetries are a part of sport, and a lot of the time are what make athletes successful (i.e. single leg jumpers might have a larger asymmetry).
Any asymmetry score that is in the 15-20% range should be a red flag to tailor your training to fix this issue.
The asymmetry may be due to an underlying dysfunction, injury, or muscle weakness. It is up to the coach to determine where the issue lies and how to correct it before competition to limit the risk of injury.
