Provides internal pressure (abdominal) that keeps the spine STABLE, reducing stress on the lower back, producing a pressure relief action on lumbar intervertebral discs and stabilizing the spine.
In this regard, one can establish that:
Involves a rapid pace:
Start too fast and use the power as a moment of inertia.
Possibility of sharp increase flexion of the cervical spine.
Shortly real and effective muscle work.
Do not work the eccentric contraction if it gets to the starting position quickly.
A slow rhythm involves:
Longer muscle work.
Use the route eccentric.
Avoid negative aspects of the fast pace themselves.
Chance of isometric stops.
The order of exercises is based on those weaker muscles (whose isolation is more complicated) have to work first. Therefore, in a session designed to abdominal training, working the transverse abdominal and pelvis prior to the devolution of other muscles, could be the most appropriate, in addition to this we could avoid some problems related to overloading in the neck muscles, for lack of fitness in people who start abdominal training programs.
