The aerobic capacity is defined as the maximum amount of oxygen that a subject can use per unit of time and body weight. Overflow Metabolism. VO2max is a measure of the ability of a person to use oxygen at a given intensity. It is calculated by dividing the oxygen consumption rate (VO2/kg/min) by the body mass (kg) and multiplying by 100.
The higher the number, the more oxygen is available to be used. In other words, a higher number indicates that the person is more efficient at using oxygen. A person with a lower number would be more likely to over- or under-utilize oxygen, depending on the type of exercise being performed and the individual’s level of fitness.

What is aerobic capacity influenced by?
The aerobic capacity of an individual can be influenced by genetics. Skeletal muscle development is influenced by the VEGF-A gene. It is located on chromosome 15q13.2 and is composed of two exons and two introns. One copy is expressed in muscle cells and the other is not.
VEGFR2 is a transcription factor that regulates the expression of several genes involved in energy metabolism, such as the glycolytic enzymes pyruvate dehydrogenase (PDH) and glycogen synthase kinase 3 (GSK3). PDH enzyme is responsible for the conversion of lactate to acetyl-CoA, which is then used as an energy source for muscle contraction.
GSK3 is an enzyme that catalyzes the synthesis of ATP, a molecule that is used by muscles to generate energy.
Is aerobic capacity skill related?
While aerobic capacity in schoolchildren has been found to be related to the abilities in explosive- and motor skill-demanding movements involving either the legs or arms (Okely et al., 2001), changes in various components of physical fitness during childhood and adolescence have not been investigated. The aim of this study was to investigate the effects of aerobic fitness on the development of motor skills in children and adolescents.
A cross-sectional design was used to examine the relationship between the number of hours per week that children spent in physical activity and their ability to perform motor tasks. The study population consisted of children aged 6–18 years who participated in the National Health and Nutrition Examination Survey (NHANES), a nationally representative sample of the U.S. civilian noninstitutionalized population.
Physical activity was assessed using a self-administered questionnaire administered at baseline and at the end of each school year. Motor skill development was measured using the Child Behavior Checklist-Revised (CBCL-R) and the Wechsler Intelligence Scale for Children (WISC-III). The results showed that the children who spent the most time in moderate-to-vigorous aerobic activity had the highest scores on all three tests.
How does aerobic capacity relate to health and fitness?
Aerobic capacity refers to your body’s ability to efficiently use oxygen. The more aerobic capacity you have, the more intense the exercise you can do. (VO2max) is the maximum amount of oxygen that can be used by your muscles during exercise.
It is measured in ml per kilogram of body weight per minute (ml/kg/min) and is expressed as a percentage of your maximum heart rate (HRmax). The higher your VO 2max, the faster your heart can pump blood to the muscles and the less oxygen is required to do the work of breathing.
This is why it is so important to maintain a high level of aerobic fitness.
What is aerobic capacity quizlet?
The ability to take in, transport and use oxygen to sustain prolonged periods of exercise. Aerobic capacity is a measure of the amount of oxygen that can be taken in and used by the body. It is measured in milliliters per kilogram of body weight per minute (ml/kg/min). The higher the aerobic capacity, the more oxygen is available to be used during exercise, and the longer the duration of an exercise session.
For example, a person who has a VO2max of 100 ml/ kg/ min will be able to exercise for an hour and a half before needing to replenish his or her oxygen supply. A person with an aerobic fitness level of 80-85% will have enough oxygen in the blood to last for at least two hours.
Why is aerobic capacity measured?
If you measure your aerobic capacity, you can see how well your body performs. The more you work on your cardiovascular endurance, the higher your aerobic capacity or VO2 max will be. Aerobic capacity refers to the amount of oxygen you can use during exercise. It is measured in milliliters per minute (ml/min) or kilocalories per kilogram (kcal/kg).
VO 2 max is a measure of your maximum aerobic power, which is the highest level of exercise that you are able to perform at a given intensity. A person who can perform a 100-meter sprint at 80 percent of his or her maximum heart rate will have a VO two max of 80.
This means that he or she is capable of performing 100 meters in less than 80 seconds. In contrast, someone who is unable to maintain a steady pace for more than a few seconds will not have the ability to sustain a sprint for a long period of time.
What is a component of aerobic capacity?
Vo2 max is the maximum amount of oxygen your body can consume during aerobics. The number of liters of oxygen your body consumes per minute is the measurement. Aerobic capacity is measured on a scale from 0 to 100. The higher the value, the more oxygen you can take in during a given period of time.
For example, if you have a VO2max of 100, and you are able to take 100 ml of air in one minute, you will have an oxygen consumption of 1 ml/kg/min. If you were to do this for an hour, that would mean you would have consumed 1,000 ml per hour.
This is why it is important to know how much oxygen is in the air you inhale and exhale, as well as how long it takes you to get back to your starting point.
