Chapter 11: Lesson 5 Flashcards
Cardiorespiratory fitness
The ability of the circulatory and respiratory systems to provide the body with oxygen during activity.
Cardiorespiratory assessments
Protocols intended to measure the aerobic fitness of an individual.
Mitochondria
The part of the cell that uses nutrients to create energy for the cell; commonly known as the powerhouse of the cell.
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).
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.
