Resistance Training Concepts Flashcards
General Adaptations Syndrome (GAS)
Describes the way in which the body responds and adapts to stress
Alarm Reaction Stage
The inicial reaction to an stressor
Delayed- Onset muscle soreness (DOMS)
Pain or discomfort often felt 24-72 hrs after intense exercise or unaccustomed physical activity
Homeostasis
The process by which the human body strived to maintain a relatively stable equilibrium
Progressive Overload
Increasing the intensity of 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 starting that the body will adapt to the specific demands that are placed on it , also known as the specific adaptations to imposed demands ( SAID ) principles
Mechanical Soecificity
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
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 muscle cell, the myofilaments ( actin and myosin) are contrained within a myofibril
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 X Velocity or Work ~ divided by Time
Rate of force production
Ability of muscles to exert maximal force output in a minimal amount of time
