5.20 Resistance Training Concepts Flashcards
Describes the way in which the body responds and adapts to stress (weight in resistance training)
this is considered a good form of stress - eustress
General adaptation syndrome (GAS)
eustress
stress which helps the body adapt over time and become better accustomed to resistance exercise
The GAS model outlines three stages of response to stress
Alarm reaction
Resistance development
Exhaustion
The initial reaction to a stressor.
alarm reaction stage
reaction: An initial reaction to stressor, such as fatigue, joint stiffness, or DOMS
The process by which the human body strives to maintain a relatively stable equilibrium.
homeostasis
Increasing the intensity or volume of exercise programs using a systematic and gradual approach.
progressive overload
The body increases its functional capacity to adapt to a stressor.
resistance development stage
reaction: Increased functional capacity to adapt to a stressor, such as increasing recruitment of muscle fibers
Prolonged stress or stress that is intolerable and will produce exhaustion or distress to the system.
exhaustion stage
reaction: A prolonged intolerable stressor that produces fatigue and leads to injury or a breakdown in the system
condition in which an athlete or fitness client experiences fatigue, declining performance, and burnout. This is a chronic condition and occurs primarily because of overly aggressive training schedules; more particularly, it is a sequence of training bouts that is abruptly increased, exists for an extended period, or entails high-volume or high-intensity exercise with inadequate recovery and regeneration
overtraining syndrome
temporary condition when compared to overtraining syndrome. Like overtraining syndrome, this also involves decrements in performance, often as a result of fatigue. If not identified, it can lead to overtraining syndrome. While these terms may sound the same, the subtle difference has to do with the amount of time for performance restoration, not the type of duration of training stress
Overreaching
A principle stating that the body will adapt to the specific demands that are placed on it; also known as the specific adaptations to imposed demands (SAID) principle.
Principle of specificity
SAID
specific
adaptation to
imposed
demands
Some types of specificity include the following:
Specificity of energy systems (anaerobic and aerobic)
Specificity of mode of training
Specificity of muscle groups and movement patterns
Posture specificity
Refers to the weight and movements placed on the body.
mechanical specificity
Refers to the weight and movements placed on the body.
mechanical specificity
example, the development of muscular endurance of the legs requires light weights and high repetitions when performing leg-related exercises
Refers to the speed of contraction and exercise selection.
neuromuscular specificity
ex: To develop higher levels of stability while pushing, chest exercises will need to be performed with controlled, unstable exercises and at slower speeds
Refers to the energy demand placed on the body.
metabolic specificity
ex: To develop maximal strength or power, resistance training programs require longer rest periods to replenish adenosine triphosphate (ATP), so the intensity of each exercise can remain high. Energy will be supplied primarily via the anaerobic pathways
A high-energy molecule that serves as the main form of energy in the human body; known as the energy currency of the body.
Adenosine triphosphate (ATP)
main adaptations that occur from resistance training include
stabilization, muscular endurance, hypertrophy, strength, and power
The body’s ability to provide optimal dynamic joint support to maintain correct posture during all movements.
stablization
The ability to produce and maintain force production for prolonged periods of time.
muscular endurance
The enlargement of skeletal muscle fibers.
muscular hypertrophy
characterized by an increase in the cross-sectional area of individual muscle fibers resulting from an increase in myofibril proteins
The contractile components of a muscle cell; the myofilaments (actin and myosin) are contained within a myofibril.
myofibrils
The ability of the neuromuscular system to produce internal tension to overcome an external load.
strength
A motor neuron and all of the muscle fibers that it innervates.
motor unit
T/F: strength-focused resistance training is designed to match the characteristics of type I muscle fibers (quick-contracting, high-tension output, prone to fatigue)
false; type II
Force × Velocity
or
Work ÷ Time
ability of the neuromuscular system to produce the greatest possible force in the shortest possible time
power
Ability of muscles to exert maximal force output in a minimal amount of time.
rate of force production
most common method of measurement is
watts
Which term refers to a motor neuron and all the muscle fibers it innervates?
motor unit
Important components that specify how each exercise is to be performed; also known as exercise training variables.
acute variables
Acute variables include the following:
Repetitions Sets Training intensity Repetition tempo Rest intervals Training volume Training frequency Training duration Exercise selection Exercise order
questions a CPT must be able to answer with confidence for all clients
Which exercises are most appropriate for my client?
Which exercises are contraindicated for my client (i.e., should not be used)?
Which exercise intensities are appropriate for my client?
How many exercises are appropriate for my client?
How many sets and repetitions should my client perform?
How many days per week should my client train?
One complete movement of an exercise.
repetition
example, performing 15 repetitions of a biceps curl involves curling the weight upward for a total of 15 times
T/F: Repetitions are inversely related to the load lifted. For example, the heavier the load, the lower number of repetitions can be achieved. Repetitions can be categorized as low (1 to 5), moderate (6 to 12), and high (12+).
true
A group of consecutive repetitions.
set
True/False: There is an inverse relationship between sets, repetitions, and intensity. The individual usually performs fewer sets when performing higher repetitions at a lower intensity (lighter weight) and more sets when performing lower repetitions at a higher intensity (heavier weight).
true
An individual’s level of effort compared with their maximal effort, which is usually expressed as a percentage.
training intensity (i.e., load)
what is commonly expressed as a percentage of one repetition maximum (1RM) and equates to the number of repetitions that can be performed with a given weight.
training intensity
What are the suggested acute variables for:
Training adaptation: Stabilization and muscular endurance
Moderate to high repetitions: ~12–20 or higher
Low to moderate sets: ~1–3 sets
Low to moderate training intensities: ~50–70% 1RM
