1.Muscle size :-
Muscle strength directly depends on the crosssectional area of muscle. It is well known that bigger and larger muscle can produce more force. The force produced by the same size of muscles in males and females is approximately the same but males are found to be stronger because they have larger and bigger muscles in comparison to females.
2. Body weight :-
There is a positive correlation between the body weight and strength individuals with then heavier body weight are stronger than the individual with the lighter weight.
3. Muscle composition : -
The muscle composition is genetically determined and can not be changed by any type of training.
4. Nerve impulses :-
The nervous system also play a role in muscle strength. The brain and nervous system has power to activate more motor units when they need to generate larger amount of force. Through the strength training, the body learns to recruit more motor units and increase these units.
5. Age and gender :- Age and gender is a factor which effects the muscle strength. Muscle strength decline with the age but it is primarily due to a decrease in muscle cross sectional area and decline in the amount of contractil tissues within the muscle fibres. Regular strength training limits loss of muscle strength with ageing.
