Conconi test
The Conconi Test is a sports medicine test intended to measure an individual's maximum anaerobic and aerobic threshold heart rates.
The test measures a person's heart rate at different loads. The points are plotted on a graph with heart rate on one axis and power on the other axis; the graph's deflection point indicates the aerobic threshold. The heart rate increases linearly up to the deflection point, where the heart rate reaches AT. The test continues for a while, under increasing load, until the subject has gone well past the anaerobic threshold.
