Quiz 3: Resistance Exercise Flashcards
(117 cards)
What is resistance exercise?
an activity in which a dynamic or static muscle contractions is resisted by an outside force applied manually or mechanically
What is muscle performance?
the capacity of a muscle to do work (force x distance)
What are the 3 key elements of muscle performance?
- strength
- power
- endurance
What are some factors that can affect muscle performance?
- injury
- disease
- immobilization
- disuse
- inactivity may impair muscle performance and result in weakness and muscle atrophy
What is strength?
muscle’s ability to overcome resistance in one powerful effort (ability to lift)
What is functional strength?
neuromuscular system’s (ability to generate force) for everyday tasks
What is strength training?
gradually (increasing resistance) to build muscle strength systematically
What is power?
speed of muscle force application (force x distance/time)
What are some examples of power?
quick intense movements
- vertical jump
- shot put
- racing up a flight of stairs
What is the difference between aerobic and anaerobic?
Aerobic: with oxygen
Anaerobic: without oxygen
What is endurance?
Withstand fatigue during long, low-intensity movements
What is cardiopulmonary endurance (CPE)?
heart and lungs ability to efficiently supply oxygen for prolonged, large muscle movements
What are some examples of CPE?
- walking, cycling, swimming, or upper extremity ergometry
What is dynamic muscle endurance?
the ability of a muscle to contract repeatedly against a fixed resistance over extended period
What is static muscle endurance?
the ability of a muscle to sustain a muscle contraction against a fixed resistance over extended period
What is the overload principle?
alteration of intensity or volume of exercise
What is the SAID principle?
always base the specificity of an exercise program on the projected outcome
What is the reversibility principle?
use it or lose it
What are the 3 energy systems in the body?
- aerobic/oxidative development
- (anaerobic) glycolytic development
- ATP-PCr development
______ stores blood supply
Energy
True or False:
Muscles need adequate sources of energy to contract generate tension and resist fatigue.
True
What does fatigue look like in a muscle?
the diminished response of a muscle to a repeated stimulus
What does fatigue look like in cardiopulmonary (whole body)
The diminished response of an individual to prolonged physical activity such as jogging, walking, cycling, or repetitive work
What is the threshold for fatigue?
stopping point
- the level of exercise that cannot be sustained indefinitely
