What best describes VO2 max?

What best describes VO2 max?

VO2 max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can utilize during intense or maximal exercise. This measurement is generally considered the best indicator of cardiovascular fitness and aerobic endurance.

What is VO2 Max determined by quizlet?

Terms in this set (9) What tissues (e.g., heart) and physiological variables (e.g., cardiac output) determine VO2 max? VO2 max depends on the cell’s ability to extract and use oxygen, on the cardiac output of the heart, on the respiratory system’s ventilation (respiratory muscles).

What physiological factors determine VO2 max?

Factors affecting VO2max

• Age.
• Gender.
• Genetics/physiology.
• Altitude.
• Body type/body composition.
• Training status.
• Exercise type.

What is true cardiorespiratory endurance?

Cardiorespiratory endurance is the level at which your heart, lungs, and muscles work together when you’re exercising for an extended period of time. This shows how efficiently your cardiorespiratory system functions, and is an indicator of how physically fit and healthy you are.

What is VO2 max dependent on?

VO2 max depends on oxygen delivery (atmospheric O2, air exchange in the lungs, pumping power of the heart, and arterial blood flow to the muscles) and also oxygen demand by the tissues (mitochondria consume nearly all of the oxygen utilized) [14].

What does VO2 max mean?

VO2 max measures how much oxygen (usually in milliliters) you breathe in while exercising as hard as you can. The more oxygen you inhale, the more energy your body can use. Higher VO2 max usually means better physical fitness.

What does a VO2 measure?

Which of the following is true of VO2 max?

Which of the following is true concerning VO2 max? It is a valid measure of cardiovascular fitness. a combination of aerobic/anaerobic metabolism, with most of the ATP coming from anaerobic sources.

What is VO2 max influenced by?

There are many factors that can influence V̇O2max, e.g. heredity, training, age, gender, and body composition. Generally, V̇O2max declines with age (about 2% per year after age 30) and males typically have a greater oxygen consumption value than females.

What is cardiorespiratory endurance quizlet?

Cardiorespiratory Endurance (CR): – The ability of the ♥, lungs, and blood vessels to deliver adequate amounts of Oxygen to the cells to meet the demands of prolonged physical activity.

What is cardiorespiratory fitness quizlet?

Cardiorespiratory Fitness. -The ability of the circulatory and respiratory systems to supply oxygen-rich blood to skeletal muscles during sustained physical activity. -Ability to perform large-muscle, dynamic, moderate-to-high intensity exercise for prolonged periods.

Is VO2 max related to weight?

The researchers do further analysis to show that relative VO2max is actually inversely proportional to fat mass — that is, the more body fat you have, the lower your relative VO2max. In fact, fat mass is a better predictor of relative VO2max than exercise performance (how far/fast you go in the VO2max test)!

Is VO2 max related to maximal cardiac output?

Central Circulation & VO2 Max Alterations in blood volume have an impact on end-diastolic volume, maximal stroke volume, and therefore maximal cardiac output. Plasma volume expansion acutely, in untrained subjects, has been shown to increase the VO2 max.

Which of the following is true of Vo2 max?

What is Vo2 max heart rate?

Your Vo2 max is a measure of the maximum amount of oxygen your body can use during exercise. The best way to increase your Vo2 max is to exercise near your maximum heart rate. Elite athletes in endurance sports usually have remarkably high Vo2 maxes.

What unit is Vo2 max measured in?

Liters per min
The units of measurement are all metric: Absolute VO2 = Liters per min (L/min) Relative VO2 = milliliters per minute per kilogram (a unit of mass) which is rewritten as milliliters per kilogram per minute or mL/kg/min (1,000 mL = 1.0 L).

What does VO2 max test measure?

A VO2 max test is a maximal exercise test performed on a treadmill or bike while connected to a machine capable of analyzing your expired air. Your test provides data on how much oxygen you use as you exercise and determines the maximal oxygen you can consume during exercise.

What is VO2 max heart rate?

What is VO2 max level?

What are examples of cardiorespiratory endurance activities quizlet?

Examples of cardiorespiratory exercises or aerobic exercises are:

• Walking.
• Jogging.
• Swimming.
• cycling.
• cross-country skiing.
• Water aerobics.
• Rope skipping.
• Aerobics.
