First topic of physical strength

This question is incomplete. Anyway, I will give you an explanation on the most important topics about physical strength.

Explanation:

   Physical or muscular strength can be defined as the ability of a muscle to develop tension against a load in a single effort during contraction.

Strength is an essential component for the performance of any human being and its formal development cannot be forgotten in the preparation of athletes.

When defining force, we distinguish two different concepts: force as a physical magnitude and force as a presupposition for the execution of a sporting movement (Harre, 1994). From the perspective of physics, muscle strength would be the ability of the musculature to accelerate or deform a body, keep it immobile or slow down its movement.

In the field of sport, there are as many definitions of force as there are authors. González-Badillo (1995), defines force as the ability to produce tension in the muscles when activated, or as it is commonly understood, when contracting.

For Verkhoshansky (1999), force is the product of a muscular action initiated and synchronized by electrical processes in the nervous system. Force is the ability of a muscle group to generate force under specific conditions.

Kuznetsov (1989), Ehlenz (1990), Manno (1991), Harre and Hauptmann (1994) and Zatsiorsky (1995) define it as the ability to overcome or oppose external resistance through muscular tension.

Knutggen and Kraemer (1987) define force as the maximum tension manifested by the muscle or muscle group at a given speed.
