Ch 13 - Resistance Flashcards
General adaptation syndrome
how the body responds and adapts to stress
Stages of stress response
alarm reaction, resistance development, exhaustion
Alarm reaction
initial response to stressor; activates protective processes; increases oxygen and blood supply
DOMS
delayed-onset muscle stress, felt 24-72 hours after intense or unaccustomed exercise (an alarm reaction)
Resistance development
increased functional capacity to adapt to stressors
Exhaustion
prolonged or intolerable stress that produces distress and can lead to injury
Periodization
division of training program into smaller components, allows smaller, slower progressions to avoid exhaustion
SAID
specific adaptation to imposed demands, principle of specificity; that body will adapt to specific demands placed on it (get better at what it’s repeatedly asked to do)
Type I muscle fibers
slow-twitch, slower to produce max tension, slower to fatigue, small fibers; needed for long-term contraction (posture, stabilization); used in stabilization training
Type II muscle fibers
fast-twitch, quicker to produce max tension, quicker to fatigue; needed for force and power; used in strength training
Mechanical specificity
weight and movements placed on body (load and reps)
Neuromuscular specificity
exercise selection and speed of contractions
Metabolic specificity
energy demand placed on body (length of time and rest periods)
Stabilization
ability to provide optimal dynamic joint support to maintain correct posture during movement; getting the right muscles to fire with the right force, in the right plane, at the right time
Muscular endurance
ability to produce and maintain force production for prolonged periods; helps with stabilization
