Core stability : Local as well as Global musculature

What is core ?

It is a muscular box with the abdominals in the front, paraspinals and gluteals in the rear, the diaphragm at the top,  and the pelvic floor and hip girdle musculature at the bottom. Within the “box” multiple muscles help to stabilize the
spine and pelvis as well as transmit forces through the kinetic chain.

Defination of core stability ?

The core through three subsystems, the passive subsystem, active subsystem, and the neural control subsystem. It was proposed that these subsystems were highly integrated and optimization of all three were necessary for normal biomechanics of the spine. If any one of these subsystems became impaired it could lead to instability of the spinal column predisposing an individual to injury, dysfunction, and pain.

Generally, core stability comprises the lumbopelvic-hip complex and is the capacity to maintain equilibrium of the vertebral column within its physiologic limits by reducing displacement from perturbations and maintaining structural integrity.

Objective of core strengthening:

Strength is defined as the maximum force that a muscle or muscle group can generate at a specific velocity. Power refers to the amount of force that can be generated in a given time period 10 repeatation maximum squat is a measure of absolute strength, where the force of a racket on a ball a  given velocity determines the amount of power that is Imparted to the ball.

The crucial question is how core strength relates to each of these situations.
