Physical strength is the ability of a person or animal to exert force on physical objects using muscles. Increasing physical strength is the goal of strength training. In physics, force is an influence that may cause an object to accelerate. ... This article or section does not cite any references or sources. ... Strength training is a blanket term for all exercises that develop the strength and size of skeletal muscles. ...

Relation to muscle types

An individual's physical strength is determined by two factors, their genetic inheritance of muscle fiber types and their degree and type of strength training they may undertake. Individuals with a high proportion of type I slow twitch fibers will be relatively weaker than a similar individual with a high proportion of type II fast twitch fibers, but would have a greater inherent capacity for physical endurance. The genetic inheritance of muscle fiber type sets the outermost boundaries of physical strength possible (barring the use of enhancing agents such as testosterone), though the unique position within this envelope is determined by training. Individual muscle fiber ratios can be determined through a muscle biopsy. Other considerations are the ability to recruit muscle fibers for a particular activity, joint angles, and the length of each limb. For a given cross-section, shorter limbs are able to lift more weight. DNA, the molecular basis for inheritance. ... Global view of a neuromuscular junction: 1. ...
