Heart rate is the number of heartbeats per unit of time, typically expressed as beats per minute . Heart rate can vary as the body's need to absorb oxygen and excrete carbon dioxide changes, such as during exercise or sleep....

The test measures a person's heart rates at different loads (e.g. faster speeds on a treadmill). The points are plotted on a graph with heart rate on one axis and load^2 or heart rate on the other axis; the graph's deflection point indicates the aerobic threshold

. The heart rate increases (approximately) linearly up to the deflection point, where the heart rate reaches AT (also known as LT, lactate threshold, in more modern nomenclature). The test continues for a while, under increasing load, until the subject has gone well past the anaerobic threshold.

Accuracy

Modern recent studies have shown the Conconi test to be inaccurate and impractical in assessing the anaerobic threshold, while other recent studies are disputing or have disputed this contention, and still others proposed modifications to improve the test.
