The Basics
This term refers to the "V" in $VO2 max, representing the amount of oxygen used.
Volume
Because they have larger hearts and more hemoglobin, this gender usually has a higher $VO_2$ max
Males
his is the term for the biological traits passed down from parents that set an individual's initial $VO_2$ max levels
Genetics
This type of training (like a long run) is the best way to improve $VO_2$ max.
Aerobic Training
This habit is the worst for $VO_2$ max because it damages the lungs' ability to take in air
Smoking
VO2 max is the gold standard measurement for this type of physical endurance.
Cardiovascular (or Aerobic) Endurance
This is the approximate age range where $VO_2$ max typically peaks.
18–25 years old
Scientists estimate that this percentage—exactly half—of your aerobic potential is determined by your DNA.
DNA
Training increases this—the amount of blood pumped out of the heart per beat.
Stroke Volume
his gas from smoke blocks oxygen from attaching to your red blood cells
Carbon Monoxide
This is the specific metric used to express VO_2 max relative to body weight.
ml/kg/min
As you get older, your $VO_2$ max drops because this "maximum" heart metric also decreases.
Maximum Heart Rate
Genetics determine the natural size and strength of this specific organ, which limits how much oxygenated blood can be pumped to the muscles.
Heart
This specific training method involves high-intensity bursts followed by rest.
Interval Training
Living in this type of high-up location can actually increase your red blood cell count.
High Altitude
To reach VO_2 max, an athlete must be working at this level of intensity
This blood protein, which is higher in males, is responsible for carrying oxygen to the muscles.
Hemoglobin
This term describes an athlete who, due to their genetic makeup, sees much larger improvements in $VO_2$ max from training than others.
High Responders
Training increases the number of these tiny blood vessels around the muscles
Capillaries
This term describes a lifestyle with very little movement, leading to a weak heart.
Sedentary
In IGCSE terms, VO_2 max is the ability of the body to take in, transport, and do this with oxygen.
use (or utilize) it
After the age of 30, $VO_2$ max generally declines by this percentage per decade.
10%
Genetics dictate the density of these "powerhouses" in the muscle cells, which are responsible for actually using the oxygen to create energy.
Mitochondria
This "Threshold" is the point where the body can no longer keep up with oxygen demand.
Anaerobic Threshold
Since $VO_2$ max is measured per kg of weight, this lifestyle factor is key to a high score.
