In kinesiology, the<unk>  <unk> 1) refers to the point during exercise at which<unk> ilation starts to increase at a faster rate than VO2 (V – volume, O2 – oxygen). One's<unk>  is said to reflect levels of anaerobiosis and lactate accumulation. As the intensity level of the activity being performed increases, breathing becomes faster; more steadily first and then more rapid as the intensity increases. When breathing surpasses normal<unk> ilation rate, one has reached<unk> . For most people this<unk>  lies at exercise intensities between 50% and 75% of VO2 max. A major factor affecting one's<unk>  is their maximal<unk> ilation (amount of air entering and exiting lungs). This is dependent on their personal experience with the activity and how physically fit the person is. Comparison studies of more athletic people have shown that your<unk>  occurs at a higher intensity if you are more active or have been training for that exercise; although, in some cases shorter continuous tests can be used because of rapid alterations in<unk> ilation.
