Do you have many sprinter clients come to you with weak hip extension and lack of glute recruitment?
You can have asymmetries front to back as well. Especially when the muscles work on the same joints.
Take the front, for example. The typical bench and biceps guy that does mostly chest, and anterior chain dominant movements. He looks like a gorilla with rounded shoulders and forward head posture. That is asymmetrical. This will increase the likelihood of shoulder pain due to the lack of stability of the scapula in relation to the shoulder joint/humerous/rotator cuff musculature.

Ditto for the back. FS are more quad dominant than posterior chain. The sprinting and jumping too. They will lack optimum extension of the hips which is a key in speed. Again, I'm not saying you can't be a great athlete with them, but I am saying your more likely to get injured, and there's a chance you can be made faster, if you have better movement.

Personally I don't have any sprinters as patients, but I understand the biomechanics of them, and know others that do find these problems most commonly in the athletes I mentioned before.
