Resistance Training Concepts Flashcards
Repetition tempo
The speed at which each repetition is performed
General adaptation syndrome (GAS)
Describes the way in which the body responds and adapts to stress.
The GAS model outlines three stages of response to stress (Cunanan etal., 2018):
Alarm reaction
Resistance development
Exhaustion
Alarm reaction stage
.
The initial reaction to a stressor
Delayed-onset muscle soreness (DOMS)
Pain or discomfort often felt 24 to 72 hours after intense exercise or unaccustomed physical activity.
Homeostasis
.
The process by which the human body strives to maintain a relatively stable equilibrium
Progressive overload
Increasing the intensity or volume of exercise programs using a systematic and gradual approach.
Resistance development
The body increases its functional capacity to adapt to a stressor.
Exhaustion
Prolonged stress or stress that is intolerable and will produce exhaustion or distress to the system.
Principle of specificity
A principle stating that the body will adapt to the specific demands that are placed on it; also known as the specific adaptations to imposed demands (SAID) principle.
Mechanical specificity
Refers to the weight and movements placed on the body.
Neuromuscular specificity
Refers to the speed of contraction and exercise selection
Metabolic specificity
Refers to the energy demand placed on the body.
Adenosine triphosphate (ATP)
A high-energy molecule that serves as the main form of energy in the human body; known as the energy currency of the body
Which term refers to the way in which the body responds and adapts to stress?
General adaptation syndrome
Stabilization
The body’s ability to provide optimal dynamic joint support to maintain correct posture during all movements.
Muscular endurance
The ability to produce and maintain force production for prolonged periods of time.
Muscular hypertrophy
The enlargement of skeletal muscle fibers
Myofibrils
The contractile components of a muscle cell; the myofilaments (actin and myosin) are contained within a myofibri
Strength
The ability of the neuromuscular system to produce internal tension to overcome an external load.
Motor unit
.
A motor neuron and all of the muscle fibers that it innervates
Power
Force × Velocity or Work ÷ Time
Rate of force production
Ability of muscles to exert maximal force output in a minimal amount of time.
Which term refers to a motor neuron and all the muscle fibers it innervates?
