Topic 1 - Introduction to Exercise Flashcards
A continuum health procedure designed to improve or restore an individual’s function, or to prevent dysfunction.
Therapeutic Exercise
The following are purposes as to why one would incorporate therapeutic exercise into their lifestyle:
1) ___________ or __________ impairments*
2) _________ function*
3) ________ risk of injury/re-injury
4) __________ overall health
5) _________ fitness and well-being
1) Remediating or Preventing
2) Enhancing
3) Reducing
4) Optimizing
5) Enhancing
The following are interrelated components of physical ________.
- Muscle performance
- Cardiopulmonary/endurance
- Mobility/flexibility
- Neuromuscular control/coordination
- Stability
- Balance/postural equilibrium
Function
The process of elongation of contractile and non-contractile tissues.
Stretching
The effects and benefits of _________ include:
- Increasing flexibility and ROM
- Allowing the body to move more efficiently
- Decreasing the chance of injury
- Invigorating the respiratory, circulatory and lymphatic systems
Stretching
What are the 3 types of stretching?
1) Passive Stretching
2) Self-Stretch
3) Dynamic Stretching
A sustained or intermittent external end range stretch force, applied with overpressure by manual contact. Shortened tissue is elongated by moving a restricted joint just past the available ROM, while the patient is as relaxed as possible.
Passive Stretching
Any stretching exercise that is carried out independently by a patient after instruction and supervision by a therapist.
Self-Stretch
Active movements that take joints and muscles through their ROM. They can be functional and mimic the movements of the activity or sport you are about to perform. They can also be a series of movements to get the body ready for a certain exercise.
Dynamic Stretching
Spring-like response, recoil; the stretched material recovers its pre-tensile dimensions after the applied load is removed.
Elastic Deformation
Putty-like response; the linear deformation produced by the tensile stress remains even after the applied load is removed, resulting in permanent deformation.
Plastic Deformation
When a load is applied for an extended period of time, the tissue elongates and does not return to its original length. The amount of deformation depends on the amount of force and the rate at which the force is applied.
Creep
A stretch well beyond the normal range of motion of a joint and surrounding soft tissue, placing heavy loads on tendons and ligaments. This causes micro-tearing and inflammation and can lead to hypermobility and degenerative arthritis.
Overstretch
Tendons can rupture at __% increase in length.
10%
______________ becomes detrimental and creates instability when the supporting structures of a joint and the strength of the muscles around the joint are insufficient and cannot hold a joint in a stable, functional position during activities. Instability of a joint often causes pain and may predispose a person to musculoskeletal injury.
Overstretching
Adaptive shortening of a muscle or other soft tissues that cross a joint; which results in limitation of ROM.
Contracture
The following are conditions that can produce ____________:
- Prolonged immobilization (e.g. cast)
- Restricted mobility (e.g. sling)
- Disease (e.g. MS)
- Tissue pathology due to trauma (e.g. skin grafts, scars)
- Congenital and acquired deformities (e.g. scoliosis, torticollis)
Contractures
Inhibition of a muscle by either its own activity, or that of its antagonist.
Active Inhibition
What are 2 types of active inhibition?
1) Reciprocal Inhibition
2) Autogenic Inhibition (PIR)
The following are ___________ for stretching:
- ROM is limited because soft tissues have lost extensibility
- Restricted motion may lead to structure deformities that may be preventable
- Muscle weakness and shortening of opposing tissue have resulted in limited ROM
- Prevent/reduce the risk of musculoskeletal injuries
- May be used prior to and after exercise to reduce post-exercise muscle soreness
Indications
The following are _________________ for stretching:
- Bony block that limits joint motion
- Recent fracture
- Evidence of acute inflammation or infection (heat and swelling), or soft tissue healing
- Presence of sharp, acute pain with joint movement or muscle elongation
- Hematoma or other indication of tissue trauma
- Hypermobility already exists
- When shortened tissue provides necessary joint stability
- When shortened tissues enable a patient with paralysis or severe muscle weakness to perform specific functional skills otherwise not possible
Contraindications
Any form of active exercise in which a dynamic or static muscular contraction is resisted by an outside force.
Resistance Exercise
A single rendition/occurrence of an exercise (one work interval).
Repetition (Rep)
Pressing two dumbbells straight above your head and then lowering them back down to your shoulders constitutes one complete __________ of the dumbbell shoulder press.
Repetition (Rep)
A group of consecutive repetitions (a group of work intervals) without resting.
Set
When 12 repetitions of the dumbbell shoulder press have been performed, one ___ has been completed.
Set
The period of time between sets, which varies based on the type of exercise being performed.
Recovery/Rest Interval
What are the 3 goals of resistance exercise?
1) Increase muscular _________
2) Increase muscular ________
3) Increase muscular _____
1) Endurance
2) Strength
3) Power
Ability of muscle to perform low-intensity, repetitive, or sustained activities over a prolonged period of time.
Endurance
Muscular _________ is improved by performing exercise against mild resistance for many repetitions.
Endurance
The amount of muscular activity that can be performed without fatigue relates to muscular _________. Tolerance towards moderate levels of work performed for extended periods of time is ideal.
Endurance
Maximum force that a muscle can produce during a single contraction.
Strength
A procedure of a muscle or muscle group lifting, lowering or controlling heavy loads for a relatively low number of repetitions over a short time can increase muscular ________.
Strength
The maximal amount of resistance you can overcome relates to muscular ________.
Strength
