Why is it beneficial to release The Posterior Chain. (Will also release your sciatic nerve)
Take a look at the skeleton and follow it all the way down to the feet. You can see how the entire bundle of muscle tissue and fibres run all the way on the back of your body in almost a continuous line. If you understand fascial lines you will understand that this corresponds to the superficial back line. .
In life today most of what we do in our daily routine dosent challenge this area to be fully lengthened. (We sit for long periods) For most of us we overuse certain points along this posterior chain and underuse others - common issues such as neck and back pain arises from a highly shortened posterior chain.
Hiding inbetween all these muscle fibres are nerve pathways - When the nerves become restricted , they will not want to fire the muscle up effectively in the range of motion that is most challenging and most restricted. (An example of this would be firing of the glutes/hamstrimgs when sprinting after sitting for a long period, your glutes/hamstrings won't be able fire as well thus resulting in you running slower).
Nerves and congested fibres will just remain tight and continue to get tighter unless you mobilise it frequently and properly. .
Next time, wether your an older person struggling to put on your socks or your an athlete/ sporting person and you feel sluggish, slow or not as powerful as you should maybe take a look and see if your posterior chain is restricted of inhibited. .
Stretching, Treatment or Foam Folling will help loosen these fibres on your posterior chain while also promoting nerve and motor unit function to get you back to your best 👍
