Domains of physical function (7)
- mobility & flexibility
- muscle performance
- stability
- balance
- coordination
- cardiopulmonary fitness
- relaxation
Flexibility
ability to move without restriction and is a term used interchangeably with mobility
what term is used interchangeably with mobility
flexibility
Mobility
ability of structures and body segments to move or be moved
Mobility allows for what
range of motion
Mobility includes
passive mobility and active mobility
passive mobility
dependent on soft tissue length and extensibility
active mobility
in addition to soft tissue length and extensibility, requires neuromuscular activation
muscle performance
capacity of muscle to produce tension and do physical work
strength
the force output of a contracting muscle
Strength is directly related to
the amount of tension a contracting muscle can produce
power
the force output of a contracting muscle x velocity or distance/time
muscular endurance
ability of a muscle to perform repeated contraction over a prolonged period
What should be considered with muscle performance (3)
power, strength, muscular endurance
Stability
ability to hold a body segment in a stationary position or control a stable base during superimposed movement
How is stability achieved
through synergistic coordination of muscle contractions around a joint or joints
Balance (postural stability)
ability to maintain the body’s center of mass over its base of support.
Balance is a complex task that includes
detection, integration, and interpretation of sensory information of the body’s position in space followed by execution of appropriate musculoskeletal responses to maintain equilibrium
coordination
correct timing and sequencing of muscle contractions combined with appropriate muscle tension
Coordination is the basis of what types of movement
smooth, accurate and efficient
Coordination requires appropriate what for movement
initiation, guiding and grading
Coordination is complex integration of systems, what systems are included?
neuromuscular, musculoskeletal, vestibular and visual systems
Cardiopulmonary Fitness (cardiopulmonary endurance)
ability to perform low-intensity, repetitive, total-body activities (hiking, dancing, cycle, swim) over an extended period of time
Does cardiopulmonary system directly produce movement of the body
No
What does the cardiopulmonary system provide that allows for physical activity and function
support for the functioning of the neurological and muscular systems
relaxation requires what to relieve muscular tension and/or reduce stress or anxiety
a conscious effort
Rest
is the cessation of bodily or mental work or effort
Rest is necessary for what
proper functioning of the mind and body
Does simply stopping an activity or sleeping address physical and mental stress
no
Types of exercise (6)
Strength Power Endurance Flexibility Balance / proprioception Relaxation
Muscle Strength
ability of a muscle (and its agonist) to produce tension and force proportional to the load or demands placed on the muscle
Functional strength
the ability of the neuromuscular system to produce, reduce, or control forces in a smooth, coordinated manner during functional activities
Insufficient Muscular strength contributes to
major functional losses of activities of ADLS
Exercises that promote an increase in muscle strength requires what?
a muscle or group of muscles to control or move a heavy load for a set number of reps
What is the most common response to heavy resistance exercise?
an increase in the max force producing capacity of the muscle(s)
increased max force producing capacity of muscles is by (2)
neural adaptation & increase in muscle fiber size (hypertrophy)
how many days per week are recommended for muscle strengthening activities
2 or more
how should muscle strengthen exercises be performed?
to the point at which it would be difficult to do another repetition
how many reps per 1 set should be effective
8 to 12
Overload Principle
If muscle performance is to improve, muscles must be required to perform work against a load that exceeds the metabolic capacity of the muscle
Once the muscle is adapted & metabolic capacity has improved, muscle performance can be maintained, but will not increase unless more load is applied
What does SAID mean
Specific Adaptation to Imposed Demands
SAID Principle suggest
framework of specificity is a necessary foundation on which exercise programs should be built
Specify of training suggests
adaptive effects of training, such as increase in strength in particular muscle, are specific to the training method employed
Reversibility Principle
if a systems’ status and functioning improved as a response to exercise, then the improvement will be lost if exercise is terminated
Positive changes are transient unless (2) (for reversibility principle)
-A maintenance exercise program is sustained
or
-Training-induced improvements are regularly used for functional activities
determinants of a resistance exercise program (10)
- Alignment & stability
- Intensity
- volume
- Exercise order
- frequency
- Rest interval
- Duration
- Mode
- Periodization
- Integration
Alignment & Stabilization of joints and segments is essential
to strengthen muscles effectively & avoid substitute motion
