What are the 4 criteria for achieving the valid vo2max test?
The criteria for achieving VO 2 max were: (i) to attain an RQ higher than 1.1, (ii) to reach a plateau in oxygen consumption (change lower than 100 mL/min in the last 30-s stages), and (iii) to show a heart rate between 10 beats/min of the age-predicted maximal heart rate (Midgley et al., 2007;Amaro-Gahete et al..
What 4 factors influence an individual’s VO2 max?
There are many factors that can influence VO2max, e.g. heredity, training, age, gender, and body composition. Generally, VO2max declines with age (about 2% per year after age 30) and males typically have a greater oxygen consumption value than females.
What are the requirements of a high vo2max?
Athletes record much higher Vo2 Max scores than others. Most female athletes have a score between 60-85 ml and male athletes between 70-85. Some athletes even record a score greater than 90.
What are 3 ways your VO2 max measures your fitness level?
How is VO₂ max measured?
- Astrand treadmill test.
- 2.4 km run test.
- multistage bleep test.
What are the four criteria used to assess whether a person has reached their VO2 max following the Bruce treadmill protocol?
The criterion used to assess V̇O2max included a respiratory exchange ratio ≥ 1.10, a heart rate in excess of 90% of age predicted heart rate maximum (220-age), and identification of a plateau (<150 ml x min−1 increase) in V̇O2max despite a further increase in velocity.
What is VO2 max determined by?
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 physiological factors determine VO2 max?
Women have a lower VO2 max than men. This is primarily due to physiology. The amount of blood your heart can pump partially determines VO2 max. Blood pumping is a function of the length of the stroke of the valves, the type of fibers in the heart muscle and the size of the heart.
What determines VO2 max?
VO2 max has three primary components: Lung capacity and heart volume: The more oxygen your lungs can intake and the more oxygenated blood your heart can pump, the higher your VO2 score. Muscle efficiency: The more your muscles can extract and use oxygen from your blood, the higher your VO2 score.
What does VO2 max indicate?
VO2max is generally regarded as the best indicator of cardiorespiratory fitness. It reveals how much oxygen your body is able to consume during maximum effort. The higher your VO2max, the more oxygen your body can use – and the better your aerobic fitness.
How often should you do VO2 max training?
These studies (reviewed by Neufer, Sports Medicine 8: 302-21, 1989) have shown that a high VO2max can be maintained on as little as two or three workouts per week if the intensity of training is kept high. However, if the training intensity wanes, VO2max tends to decline as well.
Which four factors indicate that VO2 max has been reached?
Which four factors indicate that V̇O2max has been reached? Carbon dioxide plateau, oxygen consumption plateau, exhaustion, heart rate ≥ 220.
What is an ideal VO2 max score?
For example: The average non-trained male achieves a VO2 max of roughly 30 to 40 mL/kg/min. Elite male athletes V02 max can climb up as high 90 mL/kg/min, while female athletes to up to 80 to 77 mL/kg/min. A good VO2 max score for a 30-year-old man is 50-55 mL/kg/min, while a good a score for a 30-year-old woman is 45-50 mL/kg/min.
What is a good VO2 max?
Your ideal VO2 max will vary depending on your age, gender, and weight. On average, a sedentary man will have a VO2 max of 35 to 40 ml/kg/min; a sedentary woman, on the other hand, will reach approximately 27 to 30 ml/kg/min.
How accurate is the VO2 max calculation?
The results from these runners found that Garmin’s VO2 max estimation was 95% correct and the error was less than 3.5ml/kg/min. The results are reasonably accurate granting most sub maximal testing has an error of 10-15%. While this all sounds too good to be true there are some other factors that come into play.
What is a good VO2 level?
According to the cited article in New Science, VO2 max in normal persons is a range between 40 and 50 ml/kg/min. Nevertheless, in our Wiki article it is given as a single value, approximately 45 ml/kg/min.
