Chapter 13- Resistance Training Concepts Flashcards
SAID Principle (Acronym)
Specific
Adaptation to
Imposed
Demands
Principle of Specificity
The body will get better at what it is repeated asked to do
The General Adaptation Syndrome
- Alarm reaction
- Resistance development
- Exhaustion
(Stage) Alarm reaction - (Reaction)
Initial reaction to stressors such as increased oxygen and blood supply to the necessary areas of the body
ex. working-out for the first time
(Stage) Resistance development - (Reaction)
Increased functional capacity to adapt to stressor such as increasing motor unit recruitment
ex. body accostumes to stimulus
(Stage) Exhaustion - (Reaction)
A prolonged intolerable stressor produces fatigue and leads to a breakdown in the system or injury.
ex. stress fractures, muscle strains
What are the SAID types?
- Mechanical Specificity
- Neuromuscular Specificity
- Metabolic Specificity
Mechanical Specificity
Refers to the weight & movement placed on the body
ex. stronger legs= lunges with heavy weights
Neuromuscular Specificity
Refers to the speed of contraction & exercise selection
Metabolic Specificity
Refers to the energy demand placed on the body
ex. endurance development
Progressive Adaptation from Resistance Training
- Stabilization
- Muscular Endurance
- Muscular Hypertrophy
- Strength
- Power
Stabilization
Get the client stabilized & fire the right muscles in the right amount of force
Muscular Endurance
To produce force for extended period of time. high reps & low to moderate resistance.
Muscular Hypertrophy
Increase the size of muscle fibers.
ex. big biceps= moderate to heavy resistance for intermediate ranges
Strength
Muscle size is not the primary change although it may occur secondary. The goal is to move most weight in one rep 6x= bench press heavy
