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.
