24 Questions
What are the effects of immobilization on muscle?
Atrophy and fiber conversion, decreased protein synthesis, decreased neuromuscular efficiency
What are the short-term goals of a rehabilitation program?
Control pain and inflammation, maintain or improve ROM, restore and increase strength
How does sudden physical inactivity and injury impact the body?
Leads to rapid generalized loss of fitness, loss of muscle strength, endurance and coordination, decreased neuromuscular efficiency
What is the purpose of using conditioning in rehabilitation?
To prevent injury and recover from injury
What happens to the resting heart rate during immobilization?
It increases approximately 1/2 beat per minute each day of immobilization
What are the major components of a rehabilitation program?
Controlling pain and inflammation, minimizing initial swelling, maintaining or improving ROM, addressing key components
What should be routinely addressed before an athlete can return to pre-injury competitive levels?
Several key components such as controlling swelling and addressing other factors
How does conditioning relate to injury prevention?
Minimizes possibility of injury.
What is the purpose of using therapeutic exercise in rehabilitation?
To apply basic principles of strength training for rehabilitation.
What happens to the muscle when it is unused during immobilization?
Muscle atrophy and fiber conversion occur due to inactivity.
How does sudden physical inactivity impact muscle strength?
Leads to rapid loss of muscle strength.
What happens to the loss of muscle mass during immobilization?
Greatest atrophy occurring in Type I fibers.
Which of the following is one of the primary responsibilities of an Athletic Trainer (ATC) in rehabilitation?
Designing and implementing rehab plans
What is one of the effects of generalized inactivity on a highly conditioned athlete?
Decrease in muscle endurance
What is a key factor in minimizing swelling after an injury?
Elevating the affected limb above heart level
How does immobilization impact muscle atrophy?
It results in the greatest atrophy occurring in Type I muscle fibers
What is a major consideration for rehab progress relative to the injury?
Functional outcomes based on specific criteria
How does sudden physical inactivity impact the cardiorespiratory system?
It leads to an increase in resting heart rate
What are some consequences of immobilization on joints?
Decreased lubrication resulting in cartilage degeneration
What is one of the long-term goals of a rehabilitation program?
Restoring and increasing strength
How does immobilization impact ligaments and bones?
It weakens ligaments and bones due to lack of stress
What is one of the effects of sudden physical inactivity on muscle immobilization?
Atrophy and fiber conversion
What type of exercise can be used to minimize the possibility of injury and recover from injury?
Both conditioning and therapeutic exercise
What is one of the components that a well-designed rehab program routinely addresses before an athlete can return to pre-injury competitive levels?
Minimizing initial swelling after injury
Test your knowledge on the athletic trainer's approach to rehabilitation, including the immediate first aid impact, design and supervision of rehab plans, and short-term goals such as pain control and strength restoration.
