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


3/9

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


4/9

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.


5/9

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.


6/9

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.


7/9

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.


8/9

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

Strength training program Endurance program.


9/9

Said principle.

(specific adaptation to imposed demand)

Specificity of training

Transfer of training

REVERABILITY PRINCIPAL.
