Resistance Exercise

• 
  Muscle performance is....

• A. The capacity of a muscle to do work
  
  
  

• B. Ability of contractile tissue to produce tension that results in a force

• C. Work/time

• D. Ability to continually contract and resist

• 
  E. Exercise that involves a muscle contraction that is resisted

Muscle performance can be affected by all except:

• A. Biochemical factors
  
  
  
  

• B. Neurological factors

• C. Metabolic capacity

• D. Vestibulo-cochlear system

• E. Cardiovascular system

Power is defined as:

• A. The capacity of a muscle to do work
  
  
  

• B. Ability of contractile tissue to produce tension that results in a force

• C. Work/time

• D. Ability to continually contract and resist

• E. Exercise that involves a muscle contraction that is resisted

The three key elements of muscle performance are:

Strength is

• A. The capacity of a muscle to do work
  
  
  
  

• B. Ability of contractile tissue to produce tension that results in a force

• C. Work/time

• D. Ability to continually contract and resist

• E. Exercise that involves a muscle contraction that is resisted

The overload principle states:

• A. Adaptation of Wolff's law
  
  
  

• B. Is specific to the environment

• C. A load needs to exceed capacity to improve muscle strength or endurance

• D. Too many reps or too much weight results in muscle fatigue

• E. A constant resistance will result in increased strength over time
