Muscle Performance
Capacity of muscle to do work
Force x Distance
Influenced by all of the body system 3 Elements of Muscle Performance are:
i. Strength
ii. Power
iii. endurance

Resistance Exercise:
Any form of active exercise in which dynamic or staticmuscle contraction is resisted by an outside forceapplied manually or mechanically.
Also referred as resistance training
Essential element of rehab pgm for persons withimpaired function
An integral component of conditioning pgm for thosewho wish to promote or maintain health and physicalwell being

STRENGTH:Ability of contractile tissue to produce tension
Specifically muscle strength is the greatest
measureable force that can be exerted by a muscle ormuscle group to overcome resistance during a singlemaximum effort.
Functional strentghn refers to the neuromuscular
system to produce reduce or control forces duringfunctional activity in a smoth coardinated manner.

Strength training :
Strength training : it is defined as a systemicprocedure of a muscle or a muscle group lifting ,lowering , or controlling heavy loads(resistance) for arelatively low no of repetition or over a short period oftime.
Most common adaptation to heavy resistance exercise
which result in increase in muscle strength :A. neural adaptation
B. increase muscle fiber size.

Power Power: muscle power is defined as work per unit time
Strength x speed of movement.
Strength= force x distance. Power = force x distance/time.
Power training
Power can be enhance by increasing the work ordecreasing the time.

Endurance:
Refers to the low intensity, repetitive ,or sustained activitiesover a prolong period of time.
Cardiopulmonary endurance (total body endurance)
Muscle endurance (local endurance) ENDURANCE TRAININING:
It is characterized by having a muscle contract and lift orlower a light load for many repetition or sustained a muscle
contraction for the extended period of time. Adaptations:
due to increase in their oxidative and metabolic capacitieswhich allows better delivery and use of oxygen.

Overload principle If muscle performance is to improved, a load that
exceed the metabolic capacity of muscle , must beapplied that is the muscle must be challenged toperform at a level greater than that to which it isaccustomed.
Application of principle
