Means Exercising at the same % Vo2max
exercise at a 65% vo2max
VO2 max is the maximum rate of oxygen consumption as measured during incremental exercise, most typically on a motorized treadmill. In general clinical and athletic testing, this usually involves a graded exercise test in which exercise intensity is progressively increased while measuring ventilation and oxygen and carbon dioxide concentration of the inhaled and exhaled air.
The amount of oxygen the lungs can hold at full capacity
Literally terrible. Good would be 60+
Exercise increases vital capacity because the lungs need more oxygen to supply the muscles with vital nutrients and the tougher the exercise the more nutrients needed. the lungs expand during this to account for the extra need hence increasing the vital capacity
Astrand-Ryhming Test (I just had this question on my final).
The gold standard measure of cardiorespiratory endurance is maximal aerobic power ( VO2max). It is the highest rate at which the person is able to consume oxygen during exhaustive, sustained exercise.
Since VO2max is based on weight, you could just simply lose weight to make you VO2max instantly go up. Of course, this isn't advised as a method of improving VO2 max for most runners since losing weight for the sake of losing weight could compromise your health.
Generally, VO2max is a better predictor of aerobic performance and has been studied more thoroughly.
Athletes use the VO2 max test to prove fitness levels it is a fitness test which is completed by measuring the maximum amount of oxygen that your body uses during maximum exercise for a period of a minute. Cristiano Ronaldo is rumored to have a VO2 max test result of 75ml (football clubs don't officially produce these test results) he average male scores 35-40ml.
VO2max. This is one important factor (regarding lung function) which determines the total capacity for physical activity, along with muscle conditioning, nutritional factors and others.
