This muscular sling is involved in every step we take, and its control is crucial in multi-directional sports like soccer, tennis, basketball, etc.
In my last post I talked about the movement of the core and how the diaphragm, abdominals and the pelvic floor work together to provide stability. A major player to optimal function of the core and the ability to generate force along the anterior abdominal chain is the ribcage position relative to the pelvis.
Optimal skeletal alignment allows the muscles to be in the best position to be able to generate force. A typical standing posture pulls the shoulders back and lifts the ribcage into a posterior tilt, AKA "rib thrust" where the lower ribs lift away from the abdominal wall. This places the abdominals in a lengthened position, the back muscles in a shortened position and the diaphragm in a compromised position to descend on inhale.
A Typical Standing Posture
Once you get the standing position, now you can play with the oblique chain:
