Ch. 13 Flashcards
Adaptation
Most common driving force for most clients. Whether cosmetic, health, or performance.
HMS
Human movement system
General Adaptation Syndrome
When the HMS seeks to maintain balance or homeostasis
3 stages:
1) alarm reaction
2) resistance development
3) exhaustion
Alarm reaction
Initial reaction to stressor such as increased oxygen and blood supply to necessary body areas
Resistance development
Increased functional capacity to adapt, such as increasing motor unit recruitment
Exhaustion
Prolonged intolerable stressor produces fatigue and leads to a breakdown in the system or injury
The principle of adaption. SAID.
Specific adaptation to imposed demands.
HMS specifically adapts to the types of demands placed on it
Principle of specificity
Muscular endurance requires light weight and more reps
Muscular strength requires heavy weight and less reps
Neuromuscular specificity
Refers to speed of contraction and exercise selection
Metabolic specificity
Energy demand placed on the body.
For endurance training, use aerobic pathways to supply energy. Long bouts of exercise with minimal rest.
For strength, longer rest periods so intensity stays high. Primarily anaerobic pathways.
GAS
General adaptation syndrome. First established by Hans Selye. 3 stages are alarm reaction, resistance development, exhaustion.
5 categories of strength adaptation
Stabilization Muscular endurance Muscular hypertrophy Strength Power
Stabilization
Must be established before strength and other adaptations. Using the correct muscles, force, plane of motion, and timing.
Muscular endurance
To maintain force production for a time period. Helps increase core and joint stabilization.
Hypertrophy
Enlargement of skeletal muscle fibers in response to increased volumes of tension.
