Chapter 5: Resistance Training Adaptations Flashcards
Innervation
Stimulation of a muscle cell by a motor nerve. (NSCA CPT, pg. 91)
Recruitment
The process in which tasks that require more force involve the activation of more motor units. (NSCA CPT, pg. 91)
Size Principle
The recruitment of larger and more motor units as a response to an increased force requirement. (NSCA CPT, pg. 91)
Rate Coding
The control of the motor unit firing rate (i.e., the number of action potentials per unit of time). (NSCA CPT, pg. 91)
Hypertrophy
An increase in cross-sectional area of the muscle fiber. (NSCA CPT, pg. 94)
Hyperplasia
An increase in the number of muscle fibers. (NSCA CPT, pg. 94)
Osteoporosis
A disorder characterized by the demineralization of bone tissue that results in a decreased bone mineral density. (NSCA CPT, pg. 95)
Specificity
A strategy to train a client in a certain way to produce a particular change or result. (NSCA CPT, pg. 98)
Sarcopenia
Muscle loss due to aging. (NSCA CPT, pg. 99)
Overtraining
A condition in which a client trains too much or rests too little, or both, resulting in diminished exercise capacity, injury, or illness. (NSCA CPT, pg. 99)
Cocontraction
A condition in which muscles around a joint or the spinal column contract simultaneously to provide stability. (NSCA CPT, pg. 94)
Factors that influence Adaptations to Resistance Training.
Specificity, Sex, Age, Genetics.(NSCA CPT, pg. 98)
Detraining
Partial or complete loss of training-induced adaptations in response to cessation of training or a substantial decrease in training load. (NSCA CPT, pg. 100)
Symptoms of Overtraining from Resistance Exercise
Plateau followed by decrease of strength gains, Sleep disturbances, Decrease in lean body mass (when not
dieting), Decreased appetite, A cold that just won’t go away, Persistent flu-like symptoms, Loss of interest in the training program, Mood changes, Excessive muscle soreness. (NSCA CPT, pg. 100)
