The velocity at which a muscle contracts significantly affects the tension that the muscle produces and subsequently affects muscular strength and power. The velocity of exercise is frequently manipulated in a resistance training program to prepare the patient for a variety of functional activities that occur across a range of slow to fast velocities.
Force-Velocity Relationship

Knowledge of the factors that influence the force-producing capacity of normal muscle during an active contraction is fundamental to understanding how the neuromuscular system adapts as the result of resistance training. This knowledge, in turn, provides a basis on which a therapist is able to make sound clinical decisions when designing a resistance exercise program […]

A guiding principle of exercise prescription that has been one of the foundations on which the use of resistance exercise to improve muscle performance is based is the overload principle. Simply stated, if muscle performance is to improve, a load that exceeds the metabolic capacity of the muscle must be applied; that is, the muscle […]

The three elements of muscle performance strength, power, and endurance can be enhanced by some form of resistance exercise. To what extent each of these elements is altered by exercise depends on how the principles of resistance training are applied and how factors such as the intensity, frequency, and duration of exercise are manipulated. Because […]

Muscle performance refers to the capacity of a muscle to do work. Despite the simplicity of the definition, muscle performance is a complex component of functional movement and is influenced by all of the body systems. Factors that affect muscle performance include the morphological qualities of muscle; neurological, biochemical, and biomechanical influences; and metabolic, cardiovascular, […]

Impairments are the consequences of pathological conditions; that is, they are the signs and symptoms that reflect abnormalities at the body system, organ, or tissue level. Impairments can be categorized as arising from anatomical, physiological, or psychological alterations as well as losses or abnormalities of structure or function of a body […]

The ability to function independently at home, in the workplace, within the community, or during leisure and recreational activities is contingent upon physical as well as psychological and social function. The multidimensional aspects of physical function encompass the diverse yet interrelated areas of performance
Balance. The ability to align body segments against […]
