VO2max/Lactate Threshold Testing
Athletes who excel in endurance sports generally have a high aerobic capacity or VO2max. It is not the sole determinant of endurance performance but it is considered a fundamental measure of physiologic functional capacity for exercise.
The maximum oxygen consumption (VO2max) recorded for competitors in distance running, swimming, cycling and cross country skiing is typically twice that of sedentary men and women. Research also tells us that a VO2max below the 20th percentile for age and sex usually reflects a sedentary lifestyle and is associated with an increased risk of death from all causes.
The measurement of VO2max with gas analysis is considered the gold standard for accuracy. The calibration with our system allows for a 3 percent margin of error.
Our lab allows for testing on the Velotron Cycle Ergometer (photo above) which provides power (watts) readings which have a 1.5 percent margin of error. We can also test you on our Trackmaster Research Treadmill or Concept Two Rower.
Endurance athletes will also know that lactate threshold is another strong indicator of performance. Elite cyclists for example can obtain a lactate threshold which is greater than 80 percent of their VO2max. From a health perspective, if an individual had a lactate threshold lower than 40 percent of VO2max there may be some underlying dysfunction or disease taking place. Considerations could include anaemia, heart or lung disease, or pulmonary disease.
Allow 60-90 mins for the entire process and this includes the presentation of results.
