What is meant by specificity principle: -

Definition:
                   The adaptive effects of training in improvement of strength, power and 
                 endurance is highly specific to the training method employed.

Description:
                     Specificity of training should be considered with respect to ....
1. The desired function
2. The mode of contraction
3. The velocity of exercise
4. And the range

  
EX: 1
              If the desired functional activity requires greater muscular endurance than 
              strength, intensity and duration of exercise should be geared.

EX: 2
           If the functional outcome is to  ascend and descend stairs then exercise should  be 
           performed concentrically and eccentrically in a closed kinematic chain pattern.

EX: 3
          Swimming  may enhance performance in swimming but
          may not improve treadmill running

EX: 4
           Isotonic strength training performed
          Concentrically primarily improves concentric muscle  strength and
           Eccentric training primarily improves eccentric muscle strength

Ex: 5
          The range at which strength training performed is the range at which 
          strength gains occur.


   The basis of specificity  training is related to -
                  
               Specific Adaptation to Imposed Demands  (SAID)

They are - 
1. Physiological and morphological adaptation within the muscle
2. Metabolic adaptation
3. Neural adaptation
4. Motor learning
