chapter 11 lesson 5 Flashcards
Cardiorespiratory fitness
used to evaluate a clients capacity for performing work. this assessment serves as a significant predictor of overall health and longevity
cardiorespiratory assessment
Protocols intended to measure the aerobic fitness of an individual.
VO2 Max
Oxygen consumption (VO2) is a measure of body’s usage rate of oxygen it’s the difference between inspired and expired oxygen.
mitochondria
the part of the cell that uses nutrients to create energy for the cell commonly known as the powerhouse of the cell.
What does a higher vo2 max reflect
greater oxygen utilization and a greater capacity for physical work
YMCA 3-minute step test
An aerobic test that measures the cardiovascular fitness of an individual based on a 3-minute bout of stair-stepping at a specific cadence.
Recovery heart rate (RHR)
The number of heartbeats measured after exercise ceases, which provides some indication of an individual’s fitness level (i.e., more conditioned people recover more rapidly).
what is the ymca 2 minute step test intended for
non athletic adults who appear healthy
Rockport walk test
An aerobic test for deconditioned individuals or those of low fitness levels in which they are instructed to walk as fast as possible and have their pulse taken immediately after completing 1 mile.
1.5-mile (2.4 km) run test
An aerobic test that measures cardiorespiratory endurance by having the participant cover the distance of 1.5 miles in as short a time as possible.
Talk test
An aerobic test that measures the participant’s ability to talk or hold a conversation during an activity at various intensity levels.
Ventilatory threshold 1 (VT1)
The point at which the body uses an equal mix of carbohydrate and fat as fuel sources.
Steady-state (SS) heart rate
Any stage at which the physiological response of heart rate from the cardiovascular system becomes relatively constant in relation to the amount of work being performed (i.e., the heart rate response matches the level of work being performed).
Ventilatory threshold 2 (VT2)
The point where glucose provides nearly all of the energy for the activity.
Anaerobic energy systems
Energy systems used to perform work in which glycogen is converted to glucose and oxygen is insufficient to break down pyruvate and create adenosine triphosphate.
