Adaptive Benefits of Resistence Training:
- Psychological
- Physical
- Performance
physiological adaptations to resistance traning
- Improved cardiovascular efficiency
- Beneficial (hormone) and (cholesterol) adaptations
- Decreased body fat
- Increased metabolic efficiency (metabolism)
physical adaptations to resistance traning
- increased tissue (muscle, tendons, ligaments) strength
- Increased cross-sectional area of muscle fibers
- Increased bone density
performance adaptations to resistance traning
1. Increased neuromuscular control (coordination) 2. Increased endurance 3. Increased strength 4. Increased power
Table 13.2 General Adaption Syndrome (G.A.S.)
- Alarm
- Resistance
- Exhaustion
General Adaptation Syndrome:
A term used to describe how the body responds and adapts to stress.
Alarm Reaction:
The alarm reaction is the initial reaction to a stressor.
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.
How do personal Trainers improperly fight against adaptation?
they only increase the weight of the resistance exercise which can put added stress onto the body.
What are Type I muscle Fibers
Slow-twitch muscle fibers are smaller in diameter, slower to produce maximal tension, and more resistant to fatigue.
What do Type I muscle fibers important for?
muscles that need to produce long-term contractions necessary for stabilization, endurance, and postural control.
What are Type II Music Fibers
Type II or fast-twitch muscle fi bers are larger in size, quick to produce maxi-mal tension, and fatigue more quickly.
What do Type II fibers important for?
muscles producing movements requiring force and power such as performing a sprint.
What type of muscle is recruited for muscular endurance exercises?
Type I muscle fiber in which they are recruited with high repetitions.
Periodization:
Division of a training program into smaller, progressive stages
S.A.I.D. Principle
The degree of adaption that occurs during training is directly related to the specificity of the training program:
- Mechanical
- neuromuscular
- metabolic
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.
What are the progressions of the arms during Resistive Training: easiest to hardest
- Two arms
- Alternating Arms
- Single Arm
Mechanical Specificity:
weight and movements placed on the body.
Mechanical Specificity
Muscular Endurance
- light weights and high repetitions.
- training requires prolonged bouts of exercise
- mimimal rest periods between sets
Maximal(Muscular) Strength
- use of heavy weights.
- training requires prolonged bouts of exercise
- longer rest periods
Neuromuscular Specificity:
speed of contraction and exercise selection
Development Stages of Neuromuscular Specificity:
Stabilization training
- controlled unstable environment
- slow speeds
Strength training
- stable environment
- heavier loads
Power training
- plyometric environment
- low weight
- high velocity
Metabolic Specificity:
energy demand placed on the body.
Development Stages of Metabolic Specificity:
Endurance Training
- low weights
- high reps
Strength Training
- high weights
- low reps
Resistance Training Systems
- Single-set
- multiple-set
- pyramid
- superset
- drop-sets
- circuit training
- peripheral heart action
- split-routine
- vertical loading
- horizontal loading
Single-set
Performing one set of each exercise
What are the progressions of the Legs during Resistive Training: easiest to hardest
- Two legs stable
- One leg Stable
- Two legs unstable
- One Leg Unstable
Multiple-set
Performing a multiple number of sets for each exercise
Pyramid
Increasing (or decreasing) weight with each set
Superset
Performing two exercises in rapid succession with minimal rest
