If you’ve ever had an injury at your hamstring injury, you will know about it! You’ll go from comfortable forward bending one day to dramatically restricted, often painful forward bends the next day. This injury occurs where the tendon of the hamstring muscle knits into the membranous lining of the bone, the periosteum. In this case it is where the periosteum covers the ischial tuberosity or sit-bone. Often this is not a tear of the tendon itself but an avulsion, where the periosteum has been pulled or torn away from the bone.
Although we usually think and talk about muscles as being weak or strong, closer to the truth is that muscles are usually inhibited or facilitated, respectively. Inhibition is when neural input (from our nervous system) to the muscle has been down-regulated. Facilitation is the opposite, when neural input to a muscle is excessive or up-regulated. Facilitated muscles are often those muscles compensating for the loss of input into a movement pattern that should come from the muscle that is inhibited.
In Part 1 we looked at some of the biomechanics of neck problems and especially how to eliminate unnecessary tension in our neck when weight-bearing on our hands. In yoga asanas we commonly take our head back, extending our head and neck. Students are often cautious and hold back with this movement, concerned that it may hurt their neck. However, our necks are perfectly designed that we can gaze at the stars with wonder and delight!
Our necks are one of the most vulnerable parts of our body and once we have a neck problem they can be complex to resolve.There are a few reasons why the neck cops the brunt of it. Firstly the neck or cervical spine has the greatest range of movement possible in the entire spine. This is partially due to the specific angle of the facet joints that connect each vertebra to the next but also due to the high ratio of vertebral body to disc height.
When I first started getting into yoga anatomy it was David Keil’s website and videos that I turned to so it is always top of my list to get the chance to sit down and chat with him. Ok so it’s going to be a bit geeky but David always explains things in such an accessible way, and the more you know about the way your body works the better!
Vinyasa Flow teacher Julie Martin is director of Brahmani Yoga and leads workshops and trainings around the world. In this interview we talk about the importance of sequencing, non linear movement and how her own teaching practices have changed over the years to reflect new understandings of human anatomy and injury.
You see, around 75% of the adult population has experienced lower back pain – and I’m not talking about those who practice yoga. It’s a “thing” and not a yoga “thing.” It comes up in yoga a lot, though. Mostly around backbends though honestly, the way we forward bend can often be more to blame. But lets just stick with backbends for now. Because that’s usually where we get scared our body either completely seizes up or totally collapses.
Luckily, there doesn’t have to be an either/or. We have lots of gray to research and learn. But before we get started, lets get something clear: We are NOT going all the way. Now that THAT silly business is out of the way.
