SAID Principle
SAID Principle
Specific Adaptation to Imposed Demands; exercise programs should be built with specificity in mind, as body systems adapt over time to the stresses placed on them.
Specificity of Training
Specificity of Training
Adaptive training effects (strength, power, endurance) depend heavily on the training methods used. Exercises should mimic the desired function.
Overload
Overload
Increasing the intensity or repetitions of exercise, but always considering patient factors (pathology, age, healing) and goals, as well as body system adaptation.
Patient Factors
Patient Factors
Factors such as the patient's underlying health condition, age, and the stage of tissue healing influence exercise prescription and adaptation.

Muscle Performance
- Refers to a muscle's capacity to do work (force x distance)
- Influenced by various body systems (morphological, neurological, biochemical, biomechanical, metabolic, cardiovascular, respiratory, cognitive, and emotional)
- Key elements are strength, power, and endurance
- Limitations in muscle performance can lead to activity limitations and disability.
Resistance Exercise
- Any active exercise resisted by an outside force (manual or mechanical)
- Essential for rehabilitation and conditioning programs
- Aims to improve function, prevent future injury, and enhance physical performance.
- A comprehensive examination is crucial before prescribing a resistance exercise program.
Strength, Power, and Endurance
- Strength: Ability of contractile tissue to exert force during a maximal effort
- Power: Rate at which work is done (force x distance/time)
- Endurance: Ability to sustain muscular contraction over an extended period.
Principles of Resistance Exercise
- Overload Principle: The load must exceed the muscle's current capacity to improve performance.
- SAID Principle (Specific Adaptation to Imposed Demands): Training adaptations are specific to the type of exercise performed.
- Reversibility Principle: Gains in muscle performance will be lost if training is stopped.
Muscle Fatigue
- Muscle (local) fatigue: Progressive decline in muscle response to repeated stimuli.
- Cardiopulmonary fatigue: Decline in the body's overall response to prolonged physical activity, linked to decreased blood sugar, glycogen, or potassium levels.
- Factors affecting fatigue include intensity, frequency, and duration of exercise, as well as the person's age, condition, and more.
Factors Affecting Tension in Muscle
- Morphological factors (fiber type, size and arrangement)
- Biomechanical factors (muscle length-tension relationship)
- Neurological factors (neural recruitment)
- Metabolic factors (energy reserves & availability)
