What is Strength?

Strength is the capacity to overcome resistance through muscular action.

Types of Strength

• Force-Resistance: Capacity used for multiple repetitions against prolonged resistance. Loads are light/medium.
• Explosive Force: Capacity to overcome a load with muscle contraction velocity. Done in the shortest time possible.
• Maximum Force: Capacity to oppose a maximum load through voluntary muscle contraction. May involve motion or not.

The Locomotor System

The locomotor system is formed by bones, muscles, and joints. Muscles cover bones. They are formed by fascicles, muscle fibers, myofibrils, and myofilaments (actin and myosin). The function of an agonist muscle is to stretch when its antagonist contracts.
