This is an excellent week covering a variety of subjects from the loading phase of the Serratus Anterior to Respiratory function to assessing the Thoracic Spine.
To understand how to load the Serratus Anterior you must know the 3D function of the scapula, and what the SA will do to the scapula. To load the SA you then place the scapula in the position to lengthen the SA, and use the Thoracic Spine and Pelvis as Drivers to create the load. Sounds complex but the beauty of this strategy is it is backed by sound principles of biomechanics and muscle function. It is knowing the Chain Reaction Biomechanics of the body.
In throwing, the elbow can be overloaded in a valgus stress and injure soft tissues, bone and/ or neural tissue. What are the probable suspects of this type of injury. Consider the same side overpronation, reduced 3D motion in the same side hip and Thoracic Spine, and reduced proximal deceleration. Again, the Chain Reaction Biomechanics are key knowing what would increase the valgus extension stress to the elbow.
Breathing is more complex than we realize. Transdiaphragmatic breathing is understanding that the pressure of the diaphragm on the right will compress the liver, send transverse pressure across the viscera, and create and upwards force on the ribcage, thus assisting in expansion of the left lung. The right diaphragm is larger due to the size of the Liver. The Diaphragm is influenced by the fascial trains of the body, along with the position of the spine. Remember there is an appropriate amount of Diaphragmatic motion for each person. We want to avoid over or under inflating the lungs.
In training we can isolate the load on specific muscles by prepositioning joints to shorten or lengthen their friends. This is also called Integrated Isolation. This is a great strategy for training a muscle for sport specific function. Overload it to create a buffer of muscle function i.e the muscle can take extreme muscle loading.
Other topics covered this week included Mostability and taking away support in a subtle manner. Assessing the motion of the Thoracic Spine and Skun (Skip and run). These topics consolidated our knowledge, by drawing together several concepts into a full assessment strategy.
The weeks get better and better as we head towards GG3.
