The Strength of Muscles?

The neural adaptation, contraction speed, lever type, several factors involved in determining the power level of the tendon insertion, and cross-sectional area. While others can be improved most, of these factors, are purely genetic and can not be changed.
Motor unit adaptations

Require that motor units are recruited depending on the amount of force. During the first few weeks of resistance exercise, the rapid increase in strength is usually experienced.

As the nervous system adapts to training is due to improvements in motor unit recruitment. Further, enhance its adaptation; the burden is being lifted need to increase steadily over time.

Contraction speed

Contraction speed is an important factor that affects power. A repetition is performed in a slow and controlled motion, it will be admitted that the weight cannot be used due to a low amount of motor units. In contrast, a sharp, yet still control performed, repetition recruits more motor units. Therefore, more weight can be used with the speed of a sharp contraction.

The levers

The third element is a kind of lever force. A lever is a rigid bar that runs the center at a fixed point called. The bones in the human body act as levers and fulcrums pairs work. When muscle contracts, it applies force entry point. This shift in the center and thus causes the bone to pick with the resistance.

Three classes of levers in the body, each of which applied force location, center, and ranked on the basis of the rate of resistance. These features and benefits such as increase or decrease in power levels, the assessment of damages.

First class lever Application Center between the strength and resistance:

This is an example triceps. This muscle covers the olecranon bone (which exerts the force on the applied force) and arm (resistance) elbow (center). First class levers have a balance between speed and power.

In a second class lever, resistance is located between the applied force and the center. Extend the calcareous bone, for example, calves (applied force) to exert power and foot (body (resistance) in the ball center). The increased level of lever force, but declines offers the speed and range of motion.

The third class lever is the most common type of lever body. In this lever, the force is applied between the resistance and the center. This is an example biceps. This muscle exerts the force on the ulna bone (applied force) and performed in the arm (resistance) elbow (center). Third class levers have increased in speed but are lacking in power.

Tendon insertions

Can affect the power level that is a factor of a muscle tendon insertion. Add a tendon that far away from a joint, which is more power that can be generated from muscle. The big moment from the line of action of the muscles of the arm, or the perpendicular distance

One factor that your tendons entry is genetic and cannot be changed

Cross-sectional area

The fifth element of muscle strength is cross-sectional area of a muscle (CSA). CSA stands for one of the widest range of muscle length. A muscle with a CSA will create more power with a smaller CSA.
