2. 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. Resistance Exercise:
Any form of active exercise in which dynamic or static
muscle contraction is resisted by an outside force
applied manually or mechanically.
Also referred as resistance training
Essential element of rehab pgm for persons with
impaired function
An integral component of conditioning pgm for those
who wish to promote or maintain health and physical
well being
4. STRENGTH:
Ability of contractile tissue to produce tension
Specifically muscle strength is the greatest
measureable force that can be exerted by a muscle or
muscle group to overcome resistance during a single
maximum effort.
Functional strentghn refers to the neuromuscular
system to produce reduce or control forces during
functional activity in a smoth coardinated manner.
5. Strength training :
Strength training : it is defined as a systemic
procedure of a muscle or a muscle group lifting ,
lowering , or controlling heavy loads(resistance) for a
relatively low no of repetition or over a short period of
time.
Most common adaptation to heavy resistance exercise
which result in increase in muscle strength :
A. neural adaptation
B. increase muscle fiber size.
6. 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 or
decreasing the time.
7. Endurance:
Refers to the low intensity, repetitive ,or sustained activities
over 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 or
lower 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 capacities
which allows better delivery and use of oxygen.
8. Overload principle
If muscle performance is to improved, a load that
exceed the metabolic capacity of muscle , must be
applied that is the muscle must be challenged to
perform at a level greater than that to which it is
accustomed.
Application of principle
Strength training program
Endurance program.
