Exercises for stabilizing the lower back and sacrum
If we want to do a sport or exercise and at the same time optimally burden the body, it is important for all of our joints to be involved in the movement (in dynamic movement as well as in static activity). That can be achieved by a premise that the joint is centered.
That means that the forces involved on the joint surface are evenly distributed. In such case is the joint capsule in minimal tension and the joint ligaments are relaxed. From a biomechanical point of view is the joint under ideal static burden. Position of each joint (joint head and socket) is then mostly affected by the muscles in the close area, as well as by the more distant areas. This muscle activity of the body, controlled by the central nervous system against the external forces can be understood as a stability effort of our body.
