In an earlier post on rotational hitting, I discussed the muscles around the spine that contribute to upper rotation during the baseball swing. In this post, I am going to talk about the muscles in the hip joints themselves that contribute to rotating the player’s pelvis during the swing.
There are 8 external or lateral hip rotator muscles that will contract and cause the hips to turn toward the pitcher when the player swings the baseball bat. These 8 muscles are the gluteus maximus, gluteus medius, obturator externus, obturator internus, piriformis, superior gemellus, inferior gemellus and quadratus femoris.
These 8 muscles form the basis of power during the rotational bat swing and are combined not only with the spine rotators but also with the pushing of the back leg’s hip extensors, knee extensors and ankle plantarflexor muscles. Needless to say, this is a huge source of power when swinging the baseball bat.
You can learn about all of the muscles involved in the baseball swing by visiting my channel and in particular, you can learn more about rotational hitting there as well.
All the best.
