4. Muscle performance
Muscle performance refers to the capacity of a
muscle to do work (force distance).
• Factors that affect muscle performance include
o the morphological qualities of muscle;
neurological
o biochemical
o biomechanical influences
o metabolic, cardiovascular, respiratory, cognitive,
and emotionalfunction

5. cont….
The key elements of muscle performance are
strength
power,
and endurance
If one or more of these areas of muscle
performance is impaired, functional
limitations and disability or increased risk
of dysfunction may ensue

6. Cont….
• Many factors, such as injury, disease,
immobilization, disuse, and inactivity, may result
in impaired muscle performance, leading to
weakness and muscle atrophy.
• use of resistance exercise is an appropriate
therapeutic intervention to improve the
integrated use of strength, power, and muscular
endurance during functional movements, reduce
the risk of injury or reinjury, and enhance physical
performance.

7. Resistance exercise
• Resistance exercise is any form of active exercise
in which dynamic or static muscle contraction is
resisted by an outside force applied manually or
mechanically.
• An essential element of rehabilitation programs
for persons with impaired function
• An integral component of conditioning programs
for those who wish to promote or maintain health
and physical well-being, potentially enhance
performance of motor skills

8. Potential Benefits of Resistance Exercise
 Enhanced muscle performance: restoration, improvement or
maintenance of muscle strength, power, and endurance
 Increased strength of connective tissues: tendons, ligaments,
intramuscular connective tissue
 Greater bone mineral density or less bone demineralization
 Decreased stress on joints during physical activity
 Reduced risk of soft tissue injury during physical activity
 Possible improvement in capacity to repair and heal damaged soft tissues
due to positive impact on tissue remodeling
 Possible improvement in balance
 Enhanced physical performance during daily living, occupational, and
recreational activities
 Positive changes in body composition: ↑ lean muscle mass or ↓ body
fat
 Enhanced feeling of physical well-being
 Possible improvement in perception of disability and quality of life

9. Strength
• Muscle strength is refers to the ability of contractile
tissue to produce tension and a resultant force based
on the demands placed on the muscle. Or
Muscular strength is the most amount of force that a
muscle is able to generate in a single try or
the amount of force a muscle can produce in a single
effort
• muscle strength is the greatest measurable force that
can be exerted by a muscle or muscle group to
overcome resistance during a single maximum effort.

10. Strength training.
• The muscle strength is an integral component of
most rehabilitation or conditioning programs .
• A systematic procedure of a muscle or muscle group
lifting, lowering, or controlling heavy loads
(resistance) for a relatively low number of
repetitions or over a short period of time.
• The most common adaptation to heavy resistance
exercise is an increase in the maximum force-
producing capacity of muscle, that is, an increase in
muscle strength, primarily as the result of
Neural adaptations and
Increase in muscle fiber size

11. power
• The rate of doing work.
• The work produced by a muscle per unit of time
(force*distance/time)
• Related to the strength and speed of movement
• The rate at which a muscle contracts and
produces a resultant force and the relationship of
that force and velocity
• Anaerobic power
• Aerobic power

12. Basics -Power Training
• Increasing the work a muscle must perform during a
specified period of time or reducing the amount of
time required to produce a given force.
• The greater the intensity of the exercise and the
shorter the time period taken (to generate force) the
greater is the muscle power .
• Many motor skills in our lives are composed of
movements that are explosive and involve both
strength and speed
• Muscle strength is a necessary foundation for
developing muscle power

13. Endurance
• The ability to perform low-intensity, repetitive, or
sustained activities over a prolonged period of time
Cardiopulmonary endurance (Total body
endurance)
Muscle endurance (Local endurance)

14. Basics – endurance Training
• Muscle contract and lift or lower a light load for
many repetitions or sustain a muscle contraction
for an extended period of time
• Low-intensity muscle contractions, a large
number of repetitions, and a prolonged time
period
