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
Muscular hypertrophy
enlargement of skeletal muscle fibers in response to overcoming force from high volumes of tension; increase in cross-sectional area of individual muscle fibers
Strength
ability of neuromuscular system to produce internal tension to overcome external load
Power
force x velocity; ability of neuromuscular system to produce the greatest force in the shortest time; achieved through combination of heavyweight strength and lightweight explosive exercises
Pyramid system
increasing or decreasing weight with each set; low weight for 10-12 reps and adding weight to 1-2 reps, or high weight for 1-2 reps and removing weight to 10-12 reps
Giant set
many exercises (more than 3) a in row without rest
Drop set
perform a set to failure, reduce 5-20% for 2-4 reps, repeat for 2-3 drops
Peripheral heart action
alternating upper and lower body exercises in a circuit for 8-12 reps each; distributes blood flow and improves circulation
Split-routine system
training different body parts on different days; commonly chest/triceps/shoulders and back/biceps/legs
Vertical loading
doing 1 set of each exercise (starting with total body and upper body), then repeating the whole set
Horizontal loading
doing all sets of each exercise before moving on to the next
Compound set
a superset of exercises targeting the same body part
