Why do scientists use the VO2 Max as a measurement with each of the applicants?

Why do the scientists use the VO2 max as a measurement with each of the applicants? They use this because it is the best measurement for aerobic/cardiovascular fitness which tests the body’s ability to utilize oxygen during exercise.

When a muscle is isometrically contracted its length?

Muscle contractions can be described based on two variables: length and tension. A muscle contraction is described as isometric if the muscle tension changes but the muscle length remains the same. In contrast, a muscle contraction is isotonic if muscle tension remains the same throughout the contraction.

Which term is used to describe a muscle that is the primary muscle that contracts and produces a movement?

The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist. One way to remember which muscle is the agonist – it’s the one that’s in ‘agony’ when you are doing the movement as it is the one that is doing all the work.

Do Marathon runners have high VO2 max?

Elite marathon runners can breathe around 200 litres of air per minute during maximal exercise. This combined ability of the lungs and heart to take in and transport oxygen means that elite athletes have a very high VO2 max – the maximum amount of oxygen the body can use in a minute.

What are the 5 types of muscle movement?

What is an elite athletes VO2 max?

VO2 max is regarded as one of the key determinants of endurance performance success. VO2 max values in an average adult are around 30-45 millilitres of oxygen per kilogram of body weight per minute. But in elite endurance athletes, VO2 max increases to 65-80 ml/kg/min.
