General adaptation syndrome
(GAS) A term used to describe how the body responds and adapts to stress
The 3 stages of of response to stress, per Hans Selye
- Alarm reaction
- Resistance Development
- Exhaustion
Alarm reaction
This reaction is the initial reaction to a stressor
Delayed-onset muscle soreness
Pain or discomfort often felt 24 to 72 hours after intense exercise or unaccustomed physical activity
Resistance Development
The body increases its functional capacity to adapt to the stressor
Exhaustion
Prolonged stress or stress that is intolerable and will produce exhaustion or distress to the system
Periodization
Division of a training program into smaller, progressive stages
Principle of specificity OR specific adaptation to imposed demands (SAID principle)
Principle that states the body will adapt to the specific demands that are placed on it
Mechanical specificity
Refers to the weight and movements placed on the body
Neuromuscular specificity
Refers to the speed of contraction and exercise selection
Metabolic specificity
Refers to the energy demand placed on the body
Examples of the concept of specificity
- Mechanically - standing cable rows vs. seated machine rows
- Neuromuscular - a single leg dumbbell shoulder press vs. a seated machine shoulder press
- Metabolically - resistance training exercises in a circuit fashion w/ no rests in between sets
The benefits of “adaptive programs”
- Physiologic
- Improved cardiovascular efficiency
- Beneficial endocrine (hormone) and serum lipid (cholesterol) adaptations
- Increased bone density
- Increased metabolic efficiency (metabolism) - Physical
- Increased tissue (muscles, tendons, ligaments) tensile strength
- Increased cross-sectional area of muscle fibers
- Decreased body fat - Performance
- Increased neuromuscular control (coordination)
- Increased endurance
- Increased strength
- Increased powers
Muscular endurance
The ability to produce and maintain force production for prolonged periods of time
Muscular hypertrophy
Enlargement of skeletal muscle fibers in response to overcoming force from high volume of tension
