Anatomy
The invagination of a muscle's cell membrane that serves as a pathway during muscle excitation
What is the t-tubule?
This protein requires energy and maintains the resting membrane potential
What is the sodium potassium pump?
This contraction type produces the highest forces
What is eccentric?
This adaptation describes increases in muscle cross sectional area
What is hypertrophy?
This phase of GAS describes what occurs when a novel, new, or more intense stress than previously applied
What is alarm phase?
The area of the muscle cell that serves as a storage cite for calcium
What is the sarcoplasmic reticulum?
This phase of an action potential describes sodium influx
What is depolarization?
This principle describes orderly recruitment of the skeletal muscle
What is the [Henneman] Size Principle?
Adaptations to this intrafusal fiber results in decreased inhibition
What is the GTO?
Muscle fatigue can occur when there is an accumulation of metabolic byproducts or ______________________.
The area of the brain responsible for voluntary control of the muscle
What is the (primary) motor cortex?
This phase of an action potential describes potassium efflux (out)
This technique records electrical activity of the muscle
What is electromyography?
Muscle tension, damage and _________________ are the primary mechanism of exercise-induced muscle growth
This refers to short-term training, without sufficient recuperation, that exceeds an individual’s recovery capacity
What is overreaching?
The name for the motor neuron and the muscle cell it innervates
What is the motor unit?
This step in sliding filament theory shortens the sarcomere and creates tension
What is the Powerstroke?
This summation type describes an increase in frequency of action potentials
What is rate coding?
The pattern of motor unit recruitment in response to resistance training
What is synchronous?
This refers to performance that is enhanced after overreaching
What is supercompensation,or functional overreaching?
The efferent nerve that carries an action potential to the muscle
What is the alpha motor neuron?
What is ATP?
The tension created when a muscle is stretched beyond its resting length
What is passive?
This describes the ability of skeletal muscles to change in response to physical training
What is myoplasticity?
This refers to long term decrements in performance and prolonged maladaptation
What is overtraining?
