The key elements of muscle performance
Strength, Power and Endurance
It is an activity in which dynamic or static muscle contraction is resisted by an outside force applied manually or mechanically.
Resistance Exercise
Resistance Exercise is also referred as?
Resistance Training
It is an essential element of rehabilitation programs for persons with impaired function.
Resistance Training or Exercise
An integral component of a conditioning program for those who wish to promote or maintain health and physical well-being, enhance the performance of motor skills and reduce the risk of injury and disease.
Resistance exercise
Foundation on which a therapist determines whether a program of service of resistance exercise is warranted and likely to be affected.
Comprehensive Examination and Evaluation of the pt and client
A broad term refers to the extent that contractile elements of muscle produce force.
Muscle strength
The greatest measurable force that is exerted by a muscle or muscle group to overcome resistance during a single maximum effort.
Muscle strength
It relates to the ability of the neuromuscular system to produce the appropriate amount of force during functional activities in a smooth and coordinated manner.
Functional strength
It can contribute to major functional losses of even the most basic activities of daily living.
Insufficient muscular strength
High loads; Low Repetitions
Strength training
The development of muscle strength is an integral component of most rehabilitation or conditioning programs of all ages and abilities.
Strength training
The systematic practice of using muscle force to raise, lower, or control heavy external loads for a relatively low number of repetitions or over a short period of time.
Strength training
It is related to strength and speed of movement and is defined as the work (force x distance) produced by a muscle per unit of time ( force x distance/time)
Muscle power
Rate of performing work
Power
High intensity but have short duration
Aerobic power
Low intensity but have high duration
Anaerobic power
The greater the intensity of the exercise and the shorter period is taken to generate force, the greater the muscle power.
Power training
It is a broad term that refers to the ability to perform repetitive or sustained activities over a prolonged period of time.
Endurance
It is associated with repetitive dynamic motor activities walking, cycling, swimming, or upper extremity ergometry, which involve the use of large muscles of the body.
Cardiopulmonary Endurance
The ability of a muscle to repeatedly contract against an external load, generate and sustain tension, and resist fatigue over an extended period.
Muscle Endurance
It is sometimes used interchangeably with muscle endurance.
Aerobic Power
Light load, many repetitions, longer time
Endurance training
It is the systematic practice of using muscle force to raise, lower or control a light external load for many repetitions over an extended period.
Endurance training
The muscle must be challenged to perform at a level greater than to which it is accustomed.
Overload Principle
Light load; many repetitions and longer time
Endurance training
It refers to how much external resistance is imposed on the muscle, whereas the exercise volume includes variables that can be adjusted to increase demands on the muscle progressively.
The intensity of resistance exercise
Variables of the volume of exercise
Repetitions, sets, and frequency
The body will adapt to the specific demands placed on it.
Specific Adaptation to Imposed Demands Principle (SAID Principle)
Bones will adapt based on the stress or demand placed on them
WOLFF’S LAW
Referred to as specificity of exercise, it is a widely accepted concept suggesting the adaptive effects of training for improvement of SPE.
Specificity of training
Carryover of training effects from one variation of exercise or task to another also has been reported.
Transfer of training
Adaptive changes in the body’s system in response to a resistance exercise program are transient unless training-induced improvements are regularly used for functional activities or unless an individual participates in a maintenance program of resistance exercise program.
Reversibility of Principle
Reductions in muscle performance reflect it, begin a week or two after the cessation of resistance exercises and continue until training effects are lost.
Detraining
Factors that Influence Generation in Normal Skeletal Muscle
- Energy Stores and Blood supply
- Fatigue
- Recovery from fatigue /exercise
- Age
- Psychological & Cognitive Factors
Muscle needs adequate _______ to contract, generate tension and resist fatigue. Muscle also needs adequate _____ to provide the tissue with oxygen and nutrients and to transport waste products from muscle to other organs.
Energy stores; and Blood Supply
A complex phenomenon that affects muscle performance
Fatigue
2 types of fatigue
Muscle Fatigue
Cardiopulmonary Fatigue
Two types of fibers
Type I Fiber
Type II Fiber
Phasic, Fast-Twitch
Type II fibers
Tonic, Slow-Twitch
Type I Fibers
Great amount of tension, short time
Type II A Fibers
It is geared toward anaerobic metabolic activity and has a tendency to fatigue more quickly than type II A fibers.
Type II B fibers
Type of fibers that are more resistant to fatigue
Type I fibers
It is an acute physiological response to exercise that is normal and reversible. It is characterized by a gradual decline in the force-producing capacity of the neuromuscular system that leads to a decrease in muscle strength.
Muscle Fatigue
It is the systemic diminished response of an individual to a stimulus resulting from prolonged physical activity such as walking, jogging, cycling, or repetitive work.
Cardiopulmonary Fatigue
Factors that cause cardiopulmonary fatigue
- Decreased blood sugar
- Decreased glycogen stores in muscle and liver
- Depletion of potassium
It is the level of exercise that cannot be sustained indefinitely. It could be noted as the length of time a contraction is maintained, which sets a baseline for adaptive changes.
Threshold for fatigue
Factors that influence fatigue
Patient’s health status
Diet
Lifestyle
Adequate time for fatiguing exercise must be built into every resistance exercise program.
Recovery from Exercise
Muscle performance capability will change across the lifespan.
Age
Psychological & Cognitive Factors for muscle performance
Attention
Motivation and Feedback
A patient must be able to focus on a given task to learn how to perform it correctly.
Attention
It involves the ability to process relevant data while screening out irrelevant information from the environment and to respond to internal cues from the body,
Attention
A patient must be willing to put forth and maintain sufficient effort and adhere to the program over time.
Motivation and Feedback
Physiological Adaptations to Resistance Exercise
- Skeletal Muscle Structure
- Neural System
- Metabolic System
- Body composition
- Connective Tissue
It is well accepted that the initial, rapid gain in the tension-generating capacity of skeletal muscle from a resistance training program is mainly attributed to neural responses.
Neural Adaptations
Skeletal Muscle Adaptations
Hypertrophy
Hyperplasia
Muscle Fiber Type Adaptation
It is an increased in size of an individual muscle fiber caused by increased myofibrillar volume.

An increase of muscle fibers
Hyperplasia
A substantial degree of plasticity exists in muscle fibers concerning contractile and metabolic properties.
