About Strength and Resilience

Body function and movement is produced by three integrated systems that are interdependent. The neural system, muscular system, and skeletal system. The human anatomy is completely wired by the brain and 7 trillion nerves which commands 600 plus muscles to activate force unto a bony skeletal system, creating movement and function. Without the brain sending actions for muscles to perform and muscles being able to respond, we have no action or movement. Muscles are the enforcers of the body generating only three types of actions: concentric (muscle shortening) or producing strength other words force, eccentric (muscle lengthening) or receiving force, and isometric (holding force) or stabilization. Muscles are also attached to bony landmarks on the skeletal system which is the structure of the body known as the framework. As our mind or brain commands muscles to produce force on our bones, the skeletal structure receives force or energy creating body movement or maintaining stationery posture. Hiking is a good example for instants, walking and climbing on uneven terrain such as hills that have hard and soft ground in some. The neuro system calls on large muscle groups to contract, lengthen, and stabilize our movement simultaneously creating balance and stabilization as we move through space. Another example is bicep curls, when executing this exercise you will need to first pick up the dumbbell, which calls for your bicep and triceps to isometrically hold the weight and as you begin to curl the load. As you are curling the dumbbell the bicep contracts (shortens) while the triceps simultaneously lengthens creating what is called a coupled force. Without optimal function the body is partly inoperable and prone to injury.
