Resistance Training Concepts Flashcards
What is the resistance training principle of adaptations?
Adaptation is a function of:
General adaptation syndrome
+
Principle of specificity
What is general
Adaptation syndrome?
A term used to describe how the body responds and adapts to stress.
What are the three stages of general adaptation syndrome?
Hans Selye, a Canadian physician describes this : for adaptation to occur the body must be confronted with a stressor or some form of stress that creates a need for response.
Three stages of response:
- Alarm reaction
- Resistance development
- Exhaustion
What is alarm reaction?
The alarm reaction is the initial reaction to a stressor.
What is a delayed onset muscle soreness?
Pain or discomfort often felt 24 to 72 hours after intense exercise or unaccustomed physical activity.
What is Resistance development?
The body increases its functional capacity to adapt to the stressor.After a while the body is able to efficiently recruit muscle fibers. To increase resistance development the best way is modifying (sets reps intensity rest periods exercise selection)
What are the physiological benefits of resistance training?
Improved cardiovascular efficiency
Beneficial endocrine (hormone) and serum lipid (cholesterol) adaptations
Increased bone density
Increased metabolic efficiency(metabolism)
What are the physical benefits of resistance training?
Increased tissue ( muscle tendon ligaments) tensile strength.
Increased cross sectional area of muscle fibers.
Decreased body fat
Performance benefits of resistance training?
Increased neuromuscular control (coordination)
Increased endurance
Increased strength
Increased power
The general adaptation syndrome reaction of alarm reaction?
increased oxygen and blood supply to the necessary areas of the body
The body is forced to try and adapt to increased amounts of force on bones, joints, muscles, connective tissues and nervous system of recruitment to working muscles.
The general adaptation syndrome reaction of resistance development?
Increased functional capacity to adapt to stressor such as increasing motor unit recruitment.
The general adaptation syndrome reaction to Exhaustion?
A prolonged intolerable stressor produces fatigue and leads to breakdown in the system or injury. Such as:
Stress fractures Muscle strains Joint pain Emotional fatigue There must be appropriate rest and recuperation periods.
What is periodization?
Division of training program into smaller progressive stages.
To prevent training related injuries which more often happen to connective tissue (ligaments tendons)
What is principle of specificity or specific adaptation to imposed demands (said)?
Principle that states the body will adapt to specific demands that are placed on it. Ex:
Repeatedly lifts heavy weights , that person will produce higher levels of maximal strength. Conversely if a person repeatedly lifts lighter weights for many reps that person will develop higher levels of muscular endurance.
What do type 1 muscle fibers do?
Type 1 (slow twitch muscle fibers) Smaller in diameter slower to produce maximal tension and more resistant to fatigue. Important for muscles that need to produce long term contractions necessary for stabilization, endurance and postural control.
